Abstract:
The focus and context of the great powers' interest in the Persian Gulf has altered —often subtly, sometimes dramatically —since Britain established its hegemony in the region in the 19th century. Britain engaged in a lucrative trade, but primarily sought to protect imperial communications and the approaches to India. Today, it is oil that gives the region its strategic importance. For a number of years after World War II, Britain remained the paramount power in the area, maintaining maritime peace, handling the external affairs of the Gulf sheikhdoms, mediating local disputes, dominating trade. Since Britain's withdrawal from the Gulf in 1971, the situation has become somewhat more messy.

Abstract:
Objectives: This study aims to assess (1) the difference in the prevalence of headaches, pain, and other associated symptoms between Gulf War I (1990–1991) and Post-Gulf War I (1992–2015) veterans who served as active military personnel in the Persian Gulf and (2) how the durations of deployment may affect the prevalence of those symptoms. Methods: With institutional human subject committee approval, veterans who were accepted to the Gulf War Registry at the VA San Diego Healthcare System between July 2013 and June 2015 ( N = 367) were included in this retrospective chart review study and grouped according to the Gulf War period they served under or how long they were deployed to the Persian Gulf. Chi-square was used for categorical data analyses and analysis of variance was conducted for continuous outcomes. All analyses were two-tailed, where applicable, with α = 0.05 and Bonferroni for pairwise group comparisons. Results: Veterans who served during Post-Gulf War I or both Gulf War I and Post-Gulf War I exhibited more pain and neurological symptoms than Gulf War I veterans ( p = 0.005, p = 0.003). In addition, veterans who served ⩾12 months reported more overall pain symptoms and analgesic use than those who served less time ( p < 0.001, p = 0.024). Conclusion: The findings suggest that the length of deployment and Persian Gulf deployment period may play a role in acquiring headaches, pain, and other associated symptoms with increased analgesic consumption.

Abstract:
American policy in the Persian Gulf since the end of the Gulf war has dangerously overemphasized military instruments to protect United States interests in the region. This military focus suggests that threats to American interests are external and visible. At the same time it neglects the challenges posed to U.S. interests by internal political upheaval in the pro-American regimes of the Gulf Cooperation Council and ignores the societal disruptions associated with modernizing societies. Despite their considerable oil wealth, these polities will be increasingly vulnerable to instability if the regimes in power continue their monopoly on political power. Moreover, the highly visible and active presence of American armed forces in the Gulf today intensifies the perception of the U.S. as an imperial super power and unknowingly threatens to undermine the stability of the GCC states by providing opposition groups with a powerful symbol with which to challenge the political status quo....Persian Gulf War, U.S. Persian Gulf Policy, Gulf Cooperation Council (GCC), Political Development in Arabian Peninsula, Modernization in Arabian Peninsula

Abstract:
On 2 August 1990 Iraq invaded and occupied the Emirate of Kuwait, setting in motion a chain of events that led to the largest military build up since the Second World War. These events, which have come to be known as the Persian Gulf Crisis and War of 1990/91 provide an important background for the analysis of New Zealand's 'decision' to provide military personnel to the multi-national force being assembled in the Gulf in December 1990. Unlike many of its traditional friends and allies New Zealand had not been invited to join the United States sponsored coalition and military force due to the strained relationship that had existed between New Zealand and the United States since the ANZUS dispute of the mid-1980s. However, membership was not contingent upon an 'invitation' and New Zealand came under pressure from domestic and external sources to join the coalition, which it did so in December 1990. It is argued that this decision was possibly the catalyst for a significant improvement in the New Zealand-United States relationship and lead to a much more active international role for New Zealand in the following decade.

Abstract:
The world is faced with a difficult energy crisis due to the lackage of fossil fuels, the COVID-19 pandemic, and the effects of the Russia-Ukraine war. The regions where fossil energy resources are found and produced in the world and the regions with high-energy consumption are separated from each other. For this reason, the transportation of energy from the source regions to the regions where the use consumption is done highly brings along cost and energy security problems. The political stance of Iran and regional conflicts are being dictated that together with Hormuz, the Bab-el Mandeb strait will also be another crisis point and geopardise the fuel transportation to Europe. Closing the Strait of Hormuz will put Europe in a more difficult energy situation. The Strait of Hormuz is an important transit point controlling the outflow of the fossil-energy-rich Persian Gulf, located between Iran and Oman (the Arabian Peninsula). In this study, the possible effects of the European Union on energy security in the event of the closure of the Strait of Hormuz because of possible political crises have been examined and strategic approaches have been proposed about what alternative transportation routes and lines should be to meet energy needs.

Abstract:
The Persian Gulf connects to the Indian Ocean via the Strait of Hormuz. In this study, a three-dimensional hydrodynamic model (COHERENS) is employed in a fully prognostic mode to derive sound velocity profiles in the Persian Gulf, an evaporation-driven inverse estuary that is governed by import of surface water from the adjacent ocean and export of saline bottom gulf water through the Strait of Hormuz. During spring and summer, a cyclonic overturning circulation establishes along the full length of the Gulf. During autumn and winter, this circulation breaks up into mesoscale eddies, laterally stirring most of the Gulf’s surface waters. Output of the model shows that sound velocity in the Persian Gulf depends mainly on the temperature in the surface layer whereas the bottom layer as well as the southern part of the Gulf depends on temperature and salinity. Maximum sound velocity occurs during summer in the Persian Gulf which decreases gradually moving from Strait of Hormuz to the north western part of the Gulf. A gradual decrease in sound velocity profiles with depth was commonly observed almost at all stations in the Gulf. However, an exception occurred in Strait of Hormuz during winter. The results of the model are very close to previous observations.

Abstract:
This paper presents some of the challenges faced during a project aimed at preparing long-term wave climatology in the Persian/Arabian Gulf. Using the hourly CFSR wind fields as forcing, an attempt was made to produce a comprehensive hydrodynamic and sea state conditions data set. By comparing the wave results to various in-situ and satellite measurements, an obvious seasonal difference was observed. Wave conditions were well reproduced during winter while the wave height was generally overestimated and scattered during the summer period. After comparing the wind fields against measurements it was believed that other sources were playing an important role in wave growth and propagation. Based on available measurements, it was shown that in the summer period, where the air temperature is higher than the sea temperature, wave growth rate is lower than in the winter period. Similar real cases have been reported in some lakes, but the influence of atmospheric stability on wave climate in a relatively large sea like The Gulf has not been documented yet to the authors’ knowledge. This paper focuses on the importance of including atmospheric stability effects into wave modelling. In order to account for the stability effects, the friction velocity and surface roughness were modified in the 3rd generation wind-wave model, MIKE 21 SW, using the Monin-Obukhov similarity theory. Improvements were seen in the quality of modelled wave heights in the summer period. The Gulf is also highly affected by changes in the sea water density. The effects of varying water density on wave climate were also studied in this paper. In order to reproduce the best quality wave climatology in The Gulf, it was concluded that seasonal modelling is required and the effects of atmospheric stability should be included.

Abstract:
In recent years, application and evaluation of the efficiency of different data assimilation methods has been a subject of interest in both wave hindcasting and forecasting systems. The main goal of the current study is to assess the efficiency of an ensemble Kalman filter (EnKF) data assimilation scheme in improving the wave simulation results in Persian Gulf. The so called region plays an important role in the oil and gas industry due to its Geographical and Morphological location and housing a large number of offshore platforms. A third generation wave model, SWAN, was employed in order to simulate the wave fields in the region. The three hours updated ECMWF wind data were used as the main driving force. The OpenDA toolbox, especially developed for efficient data assimilation purposes, was employed to smooth the chaotic nature of the non-linear wave simulation scheme. The OpenDA utilizes a number of methods that are based on Kalman filter algorithm but do not require the amount of computation efforts that are incurred by the classical filter algorithm. The EnKF is a variant of Kalman filter, where probability density function of a model state is represented by an ensemble of the model state. Two sets of records for significant wave heights and peak wave periods were used in the analysis process with EnKF to estimate the error covariance matrix. At analysis time, the forecast error covariance was computed by using the model forecasts ensembles. In overall and for the wave climate modeling, the initial conditions of the numerical model were updated using the improved system state, up to the current computing time level. This is achieved by incorporating the previous measurements into the Kalman filter algorithm. The model was then run into the future, driven by the new improved state conditions. The statistical results and diagrams showed that applying EnKF scheme leads to a noticeable improvement in significant wave heights. However, the accuracy of this technique was subjected to the location and number of observation stations and also ensemble size. With larger ensembles, results of error covariance estimation are more accurate but there is a limitation due to execution time of process and efficiency of the computations.

Abstract:
Abstract Offshore reservoirs in the Southwest Persian Gulf are commonly oil-wet limestone with an average permeability of 10 md. High production of hydrogen sulfide and carbon dioxide is often encountered in the oil producer wells. The tight reservoirs are commonly drilled with water-based reservoir drill-in fluid (DIF) with high concentrations of lubricants. DIFs based on sodium chloride or calcium chloride brines with corresponding optimal breakers to remove the filter cakes were formulated and evaluated to optimize production in newly drilled wells. Fluid displacement by return permeability (RP) testing was used to evaluate the fluid/limestone rock interaction. This paper discusses the compatibility of a sodium chloride-based and a calcium chloride-based DIF with limestone formation and the necessity of introducing an optimal breaker to maximize the opportunity to achieve high production rates. RP tests are widely used to determine the potential damage caused by the DIF and production enhancement after removing the DIF filter cake with a breaker. Desired results for RP tests performed with the brine-based DIF in limestone cores were a minimum of 75% regain permeability to oil production. The cores used for the RP tests were from an analogue limestone outcrop from a Mississippian formation with permeability between 9-16 md and 14-18% porosity. DIF properties were determined following API RP-13I recommended practices. Emulsion tendency for the fluids was determined by using emulsion tendency testing with a high-speed mixer to mimic shear at the pore throat. A 10.0 lb/gal sodium chloride water-based DIF with a high content of ester-based lubricant was designed for drilling a limestone formation. A high pH close to 10 was necessary to control H2S and CO2 corrosion. The return permeability of the 10.0 lb/gal fluid was 44% using LVT-200 oil as an analogue for the native hydrocarbon permeating fluid. The low return permeability was likely caused by emulsion blockages generated by the saponification of the ester-based lubricant used in the sodium chloride-based DIF. Emulsion tendency was observed between the DIF filtrate and permeating fluid in a fluid/fluid compatibility evaluation. Therefore, a breaker system was formulated and customized to enhance RP from 44% to a minimum of 75%. In contrast, a 11.0 lb/gal calcium chloride-based DIF with pH of 9.0 and same ester-based lubricant content was evaluated using a comparable limestone analogue core and demonstrated a high return permeability (&gt;80%). Filtrate of the calcium chloride-based DIF did not form emulsions during fluid displacement in the RP test. Compatibility evaluation (return permeability) between drill-in fluids and reservoir rock is essential for oil producer wells in order to determine and avoid potential problems caused by interactions between them.

Abstract:
Abstract Water-based drill-in fluids (WB DIF) with high concentrations of lubricants and other materials that assist in reducing the fluid loss are commonly used to drill tight and high overbalance reservoirs in the south-west Persian Gulf. Exposure and damage of the formation by these products is highly possible due to the characteristic high fluid loss of WB DIF. This paper discusses the improvement of a WB DIF by adding a non-damaging polymeric product to enhance filtercake packing. The chemistry and the particle size of the polymeric product enhances the bridging properties of the calcium carbonate, thus improving the wellbore strengthening and reducing formation damage. Return permeability (RP) testing is widely used in the oil industry to evaluate fluid-rock interaction. RP testing indicates potential causes of production impediments generated after drilling by filtercake deposition and filtrate invasion. Limestone outcrops from Mississippian formation with a permeability between 9-16 md and 14-18% porosity were used for the RP tests. Damage minimization from the drill-in mud with no requirement for a breaker were the main goals for the fluid development to drill the tight limestone reservoir. Therefore, higher RP values to permeable oil was the desired outcome of the tests. The solid particles used in the drill-in fluid should generate optimal packing to achieve lower filtrate invasion. Software simulation and calculations for bridging optimization are highly recommended, but brittle particles such as calcium carbonate could deviate from the predictions after passing though the drilling nozzles and changing their size with no control. The use of non-damaging polymeric and deformable particles could help with the packing of the bridging agents and improve the wellbore strengthening by reducing filtrate invasion. This paper presents results for a fluid before and after the addition of bridging enhancer. In the study, the addition of the non-damaging polymeric material had no effect on the rheological properties of the fluid. Furthermore, the fluid loss decreased almost 40% at 160°F and 85% at 250°F using paper as a filtration media. The RP of the original WB DIF was 79.7% at 4 cm3/min using LVT-200 as a permeating oil and 89% after centrifugation, indicating connate water damage. The RP of the enhanced fluid was 92.7% at 4.0 cm3/min and 93.5% after centrifugation, indicating no damage by connate water and a significant decline in the formation damage by filtrate invasion due to the improved packing of the bridging agents. No breaker was required for the fluid due to the high RP thus decreasing cost of the operation by reducing rig time and chemical treatments. Return permeability evaluation between the drill-in fluid and reservoir rock is essential for oil producer wells to determine damage caused by the fluid, filter cake, and filtrate. Improving the packing of the bridging agents enhances fluid loss and decreases formation damage.

Abstract:
Fixed offshore platforms or Jacket type platforms are the most common offshore structures used for oil & gas Exploration & Production industry in Persian Gulf, because water depth is such that the shallow water condition is dominant. Sea waves as dominant environmental loading are cyclic and have random nature. The applied cyclic sea wave forces will lead to fatigue damages in jacket’s joints. There are different methods to investigate the fatigue life of jackets such as deterministic method, simplified method, spectral method and transient method. Spectral method is a suitable method, which can consider the random nature of sea waves in fatigue analysis. Deterministic-spectral method developed by Bishop et al. is used to estimate the fatigue life of shallow water jacket platforms. However, in this method the frequency spectrum of waves is used in the analysis, but generally sea waves are propagating in different directions with different frequencies, so directional wave spectrum can consider wave randomness more properly. In this paper, frequency domain spectral method using Deterministic-Spectral approach has been used to estimate the fatigue life of a typical jacket platform (SPD1 at South Pars Field - Persian Gulf). Base wave cases were chosen from joint histogram of height & period that is calculated based on scatter diagrams of South Pars Field. First the jacket was modeled by ANSYS software, then by applying base wave cases to it and analyzing the critical TT joint under internal cyclic forces, hot spot stress transfer functions at 8 nodes around the intersection of joint were obtained. Using JONSWAP standard spectrum and the spreading function proposed by Goda, sea state’s Power Spectral Densities (PSD) and directional spectrums are multiplied to obtain stress spectra. The fatigue damage and fatigue life then are calculated. Results indicate that the fatigue life based on frequency spectrum is less than the fatigue life based on directional spectrum.

Abstract:
Abstract Complete mud loss is a severe costly drilling problem which increases drilling time and makes wells challenging to control. Such situation was encountered during drilling of three wells from a platform in an offshore field in Persian Gulf. This unexpected problem occurred while other wells from this platform were drilled and completed according to the routine plan. Further investigations using 3D seismic data showed that, these wells had penetrated through a massive collapse feature causing extended drilling times. Buried collapse features are developed as result of karstification due to dissolution of carbonate rocks. Although karstification may be evaluated as a disturbing parameter of reservoir properties, the most critical concern about this phenomenon is difficulties in forecasting drilling mud weight due to highly unpredictable fluid transmissibility. Collapse feature has different viscoelastic properties from its surrounding sediments, therefore, it generates different seismic responses in terms of amplitude and frequency. This aspect was utilized for identification of encountered collapse feature where, a practical semi-automated approach based on seismic derived multi-attributes cubes and neural network analysis was taken. Once a sinkhole cube was generated based on the above approach, geobody of the collapse feature was extracted. Results then were thoroughly validated by mud loss intervals at wells. Close investigation of the sinkhole cube revealed that seven collapse features exist in the area of study in which, problematic wells pass through one of them. It was discovered that all collapse features are interconnected with deep-seated faults which acted as hydrocarbon migration conduit. This incident obviously emphasizes role of geohazards analysis before any offshore drilling, even in a developed field with several number of wells. As experienced, a significant part of well non-productive time can be avoided if an integrated multi-disciplinary approach is taken. The authors will describe an effective proactive approach towards geohazards and present lessons learned in the case presented to address unexpected geo-drilling incidents.
