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) ...

More than three decades have passed since Stewart Myers coined the term “real options” and introduced this new paradigm into the investment science. In the following years a number of publications in both the finance and ...

In recent time, one of the ways of optimizing hydrocarbon production is commingling production from stacked reservoirs. Commingled production refers to the production of hydrocarbon from two or more separate zones through ...

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 ...

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 ...

Niger Delta generates higher revenues for Nigeria through its abundant oil and gas resources. The region over the years has been faced with environmental challenges resulting from oil and gas operations. This study is aimed ...

In this project, the optimum position of ESP is evaluated for horizontal wells. The inflow and outflow performance of the horizontal well has been estimated using Joshi’s steady-state approximation for horizontal flow and ...

Nigeria is blessed with mineral resources but unfortunately many have been poorly exploited. This has resulted to spending huge sums of money to import these minerals rather than taking advantage of available local natural ...

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 ...

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 ...

Numerical reservoir simulators are employed to obtain meaningful and reliable solutions for an actual case due to extreme complexity of the reservoirs systems. Wilcox formation is a reservoir in the gulf of Mexico with ...

The understanding of the behaviour of vertical upward and downward two-phase flow in large diameter pipes is very important in chemical, petroleum and nuclear sector where safety is of utmost concern. This work helps to ...

Gas hydrate is one of the major plagues of gas wells in the industry, capital costs to prevent hydrate blockage in pipelines is an dissociation temperatures for the operating pressures. The model developed was tested on ...

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 ...

Wellbore instability (WI) is one of the major challenges experienced during drilling operations costing the oil and gas industry over $1 billion yearly. During the drilling, borehole breakout and drilling induced fractures ...

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 ...

Unconventional resources are of major importance to the oil and gas industry due to its enormousness, however, due to the low permeability of these resources, there is a need for hydraulic fracturing. Hydraulic fracturing ...

The main challenge of heavy oil (bitumen) is the high viscosity making it not flow easily to production wells at normal reservoir conditions. Thermal recovery methods are used to exploit heavy oil reservoirs, where oil ...
