The production of formation sand is a problem associated with most oil deposits in the world. Major Sand production effects affect safety, well or field economics and continuous production. This has prompted the continued ...

As the demand for petroleum resources increases, drilling of oil and gas wells are often carried out in challenging and hostile environments. Among the top ten drilling challenges facing the oil and gas industry today is ...

The Heart Disease according to the survey is the leading cause of death all over the world. The health sector has a lot of data, but unfortunately, these data are not well utilized. This is as a result of lack of effective ...

Liquid holdup was predicted for slug flow using the neural network toolbox available in MATLAB. Experimental data contained Liquid holdup measured at an interval of 5 seconds over a period of 12,000 time points for both ...

Surge and swab pressure computation is very important in drilling hydraulics. Most blowout problem in oil wells have been as a result of surge and swab pressures developed from running or pulling of tubular goods in ...

Energy efficiency is paramount in the quest to achieve sustainable development in the 21st century. Statistics in recent research have shown that in many sectors in any nation’s economy, which include buildings, industries ...

Hydraulic fracturing is an effective well stimulation technique which is introduced in the 1950s and widely used in the oil and gas industry. Most of the works about hydraulic fracture assumed that the fracture is symmetric ...

Hydraulic fracturing has been an effective technique to stimulate damaged wells or wells producing from low-permeability formation. It has been established that the orientation of a hydraulic fracture is perpendicular to ...

A composite reservoir is one with multiple lateral compartments; each having distinct rock and fluid properties separated by geologic discontinuities. Geologically, composite reservoirs separated by leaky faults are rife ...

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 ...

New equations for bilinear, formation linear and pseudo-radial flow regimes in an infinite commingled fractured multilayered reservoir have been developed. The equations have been extended to Tiab’s Direct Synthesis Technique ...

This dissertation presents an overview of the research work with the above caption. This research is divided into five major sections or parts. Part one deals with interfacial adhesion studies of the layers relevant to ...

Chemical method is the most efficient and flexible method of hydrate control in offshore operations. In recent times, polymers and surfactants have been used to influence the kinetics of hydrate growth and coagulation. ...
