Summary Minimum miscibility pressure (MMP) is one of the key design parameters for gas injection projects. It is a physical parameter that is a measure of local displacement efficiency while subject to some constraints due to its definition. Also, the MMP value is used to tune compositional models along with proper fluid description constrained with other available basic phase behavior data, such as bubble point pressure and volumetric properties. In general, carbon dioxide (CO2) and hydrocarbon gases are the most common gases used for (or screened for) gas injection processes, and because of

In extrusion of aluminium alloys, using porthole dies, the billet metal is split into separate metal streams during flow into the ports. After that, the streams join by seam pressure welding in the weld chamber of the die and finally flow through the die exit emerging as the desired extrusion. Because of re-joining of the metal streams the extrusion will contain as many extrusion seam welds as there are bridges in the die. Dependent on the die design the metal will flow in such a way that a gas pocket may form behind the die bridge and remain stable here throughout the course of the extrusion

One measure of geomorphic activity is sediment yield, which is defined as the amount of sediment per unit area removed from a watershed by flowing water during a specified period of time. Changes in sediment yield can signal changes in many elements of the ecosystem, including rates of weathering and erosion, climate and human activity. In present research scenario application of Remote Sensing (RS) and Geographic Information System (GIS) has useful advantages for soil erosion rate assessment with proper management planning, particularly for the remote area (Sharma et al., 2001)[1].

An oblique detonation wave in two-phase kerosene–air mixtures over a wedge is numerically studied for the first time. The features of initiation and stabilisation of the two-phase oblique detonation are emphasised, and they are different from those in previous studies on single-phase gaseous detonation. The gas–droplet reacting flow system is solved by means of a hybrid Eulerian–Lagrangian method. The two-way coupling for the interphase interactions is carefully considered using a particle-in-cell model.

Summary In a number of experiments, the efficiency of solution-gas drive for both light and heavy oils was studied. In these experiments a special coreholder was used to visually observe the formation of gas bubbles on the rock surface of a Berea core and the production from the core outlet. The results from all the experiments reveal that the critical gas saturation for three hydrocarbon liquids; 1. a light model oil, 2. an 11-API gravity oil, and 3. a 35-API gravity oil, does not exceed 3%. However, the gas mobility for the heavy oil is very low and for the light model oil very high. Consequ

Abstract. Laboratory studies have revealed that alkene-derived RO2 and longer chain alkane-derived RO2 (> C3) radicals rapidly convert to HO2 and then to OH in the presence of NO in a fluorescence assay by gas expansion (FAGE) detection cell (Fuchs et al., 2011). Three different FAGE cells that have been used to make ambient measurements of OH and HO2 in the University of Leeds ground-based instrument have been assessed to determine the sensitivity of each cell, when operating in HO2 detection mode, to RO2 radicals. The sensitivity to this interference was found to be highly dependent on ce

Abstract Sulfide stress cracking (SSC) is a kind of hydrogen related problem of pipeline steels for transportation of crude oil and natural gas containing hydrogen sulfide. To improve SSC resistance, the various techniques during steel making processes are required such as: addition of proper alloying elements, microstructure control, high cleanness and Ca treatment. However, the effect of metallurgical factors on SSC is not clearly understood in a lot of reports for improvement of SSC resistance. In this study, SSC resistance of three high strength steel plates with different microstructures

The first part of this work presents a comparison of predictions obtained with several two-equation type RANS turbulence models commonly used in industry against experimental data obtained by Whitelaw et al [1]. All examined models yield a relatively poor match in the flow region very close to the wall; agreement with the measurements improves significantly when moving further away from the wall. This concerns both the internal normal stress profiles and the average velocity profiles, the latter show improved prediction of the recirculation zone area when moving further into the main stream.

ABSTRACT: Analysis of early production data from shale condensate gas wells is crucial in assessing the effectiveness of reservoir fracturing processes. This paper presents a productivity prediction model for multistage fractured horizontal wells that considers slip flow, Knudsen diffusion, surface diffusion, and rock stress-dependent in shale condensate gas reservoirs. The model combines the multiphase material balance method and the constant component expansion test to accurately describe the phase behavior changes during the development process of condensate gas reservoirs.

The effects of creep time, eccentricity distance, cement sheath modulus of elasticity and internal casing pressure on wellbore stress were investigated using the finite element method. The results show that for a given eccentricity, the stress on the wellbore increases with creep time, affecti

However, when shale is in the plastic stage, the mathematical expression of the effective stress coefficient is still unclear. Based on Prandtl-Reuss model, the incremental constitutive relation of shale in elastic-perfectly plastic condition is established. The plastic effective stress coefficient of shale in this condition is obtained.
