Effects of Fiscal Systems on Reserves Recognition and Investment Metrics
(2019-06-23)
Petroleum reserves are affected either negatively or positively by the type of fiscal system and elements governing them. Governments, investors, policymakers, and other stakeholders have from the past been a victim of the ...
Diagnosis of Water Production using Artificial Neural Network Models
(2017-12-16)
A data-driven approach to solving the problem of excess water production was the focus of this study. In this research, several reservoir models were simulated for 26 years, and data obtained after simulation was used to ...
Analysis of Horizontal Air-Silicone Oil Plug-To-Slug Transition Flow
(2019-06-23)
The analysis of the experimental data for the air-silicone oil plug-slug transition in a 67mm id and 6m long horizontal pipe was carried out in this work. The superficial gas and liquid velocity ranged from (0.05 – 4.73) ...
Comparative Analysis of Barite Production in Africa
(2019-06-12)
Successful oil and gas well drilling require hole stabilization. Barite comprised of barium sulphate is a common mineral chiefly used by oil and gas companies in their drilling operations. Barite is used in the drilling ...
Fiscal System Design and Economic Evaluation for Petroleum Resource Development in Ghana
(2019-06-12)
Petroleum fiscal regime defines the extent to which the host government and the prospective investor can apportion risks and share project rewards.
Ghana’s petroleum industry has become an attractive place for most investors ...
Techno-Economic Feasibility of Ethane Based Enhanced Oil Recovery in Nigeria (CASE Study: Niger Delta)
(2017-12-15)
Increasing oil recovery has been one of the issues enlisted for attention in oil producing countries around the world for past decades. So many forms of oil recovery techniques have been considered; infill drilling of new ...
Pressure Transient Analysis of Bingham Fluids using Tiab’s Direct Synthesis Approach
(2019-07-23)
This study investigated transient flow response of heavy oil that exhibit Bingham fluid characteristics. Four wellbore conditions in naturally fractured reservoirs were considered which include horizontal well, hydraulically ...
Quantifying the Risks of Wellbore Failure during Drilling Operations Using Bayesian Algorithm
(2019-06-23)
The wellbore integrity plays an important role in petroleum operations like drilling, well completion and production. Caliper, Electrical image logs, Acoustic televiewers (ATV) and Optical televiewers (OTV) are some of the ...
Improving Lifting Capacity and Modelling Hydraulics of Local Based Muds Flowing Through Vertical Pipes
(2019-06-12)
Drilling mud plays an integral part in drilling operations to perform several functions some of which are to cool drill bits, provide hydrostatic pressure and give information about subsurface formation. The cutting ...
