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 ...

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 ...

Data analytics has only recently picked the interest of the oil and gas industry as it has made data visualization much simpler, faster, and cost-effective. This is driven by the promising innovative techniques in developing ...

A gas condensate reservoir is a type of gas reservoir that exists when the reservoir temperature is between the critical temperature and the cricondentherm. Compositional simulators are used to simulate these types of ...

Numerical simulators estimate the recovery volumes and the volume of fluids in-place in the reservoir as a function of time and space by solving complex partial differential fluid flow equations. For gas condensate reservoirs, ...

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 ...

A gas condensate reservoir is a type of gas reservoir that exists when the reservoir temperature is between the critical temperature and the cricondentherm. Compositional simulators are used to simulate these types of ...

The Dykstra-Parson techniques stands as the most widely used waterflood methods. The authors developed a discrete, analytical solution from which waterflood performance parameters were determined. Reznik et al extended the ...

There is insufficient literature for annular flow and applications of Machine Learning in the petroleum industry; thus, this thesis is centred on annular flow prediction. Liquid holdup and flow behaviour during annular ...

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 ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...
