Abstract:
<em>With an aim of contributing to the reduction of the greenhouse gas effect resulting from the incorporation of ordinary Portland cement as a binder material in construction and to further encourage the building of environmentally conscious structures using alternative binders, the strength characteristics of oyster shell ash and periwinkle shell ash as environmentally friendly additives to lateritic soil for pavement construction was investigated. Naturally occurring lateritic soil having a reddish-brown color was obtained from a borrow pit located at Ikorodu Local Government Area of Lagos

Abstract:
This paper presents the results of a laboratory study on the evaluation of the shear strength of compacted iron ore tailings (IOT) treated lateritic soil. Lateritic soil used was treated with 0 up to 16% IOT by weight of dry soil. Test performed include index test, compaction (using British Standard Light, BSL and West Africa Standard, WAS energies) and shear strength test. One-way analysis of variance was carried out using Microsoft Excel to determine the level of significance of IOT on the treated soil. The results of the triaxial test show that there is an improvement in the shear strength

Abstract:
To mitigate exploration risk in deepwater settings, subsurface analysis increasingly has to rely on integration of qualitative with quantitative techniques. To predict pay in turbidite sandstones, proven statistical and analytical methods can routinely be run on well and seismic inversion data. However, quantitative interpretation (QI) should begin with a responsible audit of available well logs and seismic data, succeeded by data conditioning, proceeding with quality control, and placing elastic attribute responses within their geologic context. To address these issues, we evaluate geologic c

Abstract:
Large quantities of oil contaminated soils result from pipeline vandalization, onshore and offshore oil spills every year in Nigeria. An extensive laboratory program was carried out to determine the effect of varying compactive efforts on the hydraulic conductivity behaviour of oil contamination lateritic soils. Hydraulic conductivity tests were carried out on both the natural and oil contaminated soil samples at the Reduced British Standard Light (RBSL), British Standard Light (BSL), West African Standard (WAS) and British Standard Heavy (BSH) compaction energies.

Abstract:
Pore-pressure estimation is an important part of oil-well drilling because drilling into unexpected highly pressured fluids can be costly and dangerous. However, standard estimation methods rarely account for the many sources of uncertainty, or for the multivariate nature of the system. We have developed the pore-pressure sequential dynamic Bayesian network (PP SDBN) as an appropriate solution to both these issues. The PP SDBN models the relationships between quantities in the pore-pressure system, such as pressures, porosity, lithology, and wireline-log data, using conditional probability dis

The cost saving benefits of aggregate replacement in concrete works are well documented. The utilization of Supplementary Aggregate Materials (SAMs) in concrete engineering without compromising standards in concrete works remain very attractive to both infrastructure developers and design engineers. However, there is continual search for low cost beneficial substitute materials. The mechanical properties of green concrete produced from Palm Nut Shell (PNS) as coarse aggregate was investigated.

Abstract:
Abstract Deepwater wells in offshore West Africa traverse through a complicated faulted block with sand bodies ranging in 10s of meters of thickness. A horizontal or deviated configuration allows wells to intersect and produce from multiple sand formations at once. This also brings in complexity of segmentation along the wellbore with chances of either tapping into gas cap or potential gas build up in zones around the wellbore in time which could render the well uneconomical. The study provides insight into designing advanced well completions in offshore West Africa wells with Autonomous Inflo
