Solution gas drive reservoirs are characterized by rapid and continuous decline of reservoir pressure. This rapid and continuous decline of reservoir pressure causes direct decline of reservoir performance at early stages ...

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 ...

A major drawback of directional and horizontal well drilling is the numerous complex computations required to be done while planning a well. These computations are very stressful and time consuming especially when done ...

Failure of offshore oil and gas pipelines occurs under certain conditions due to some applied mechanical forces. These conditions constitute a potential threat to the integrity of in-service life span of the pipelines ...

The study explores the investigation of the chemical composition, microstructure and mechanical properties of steel and cement mortar used in reinforced concrete. The compositions and mechanical properties of the locally ...

Many building collapsed cases have been reported throughout the West African regions. It is recorded that during some of these subsidences, many lives are lost and the vast majority end up in hospitals and clinics with ...

Like any industry, the economic success of the oil and gas industry can be no swifter than its success in corrosion control/prevention. Some oil and gas industries operate in hostile offshore environment that harbors ...

Wearing of mining tools leads to high replacement costs, machine downtime and loss of business opportunities. This work was however, aimed at improving the wear resistance of AISI 1065 and 1070 proeutectoid steels used for ...

Our ability to power modern airplanes and land based engines depends largely on the thrust generated most importantly by aero engines. Over the past 30 years material cost has become an important factor, especially in ...

Carbon dioxide (CO2) corrosion, also known as sweet corrosion of steels has increased in recent years due to the injection of CO2 into oil wells in order to increase oil recovery and production. Despite the fact that carbon ...

The cost and losses associated with corrosion annually is approximately $ 276 billion or 3.1% of the GDP in the USA, 3 - 4% of GNP in Australia, Great Britain, Japan and other countries. The associated cost and losses ...

Patients living with sickle cell disease are perpetually plagued with painful crisis episodes, caused by vascular occlusion. Over time, this leads to oxygen deprivation and the eventual damage of starved tissues and organs. ...

This paper presents the effect of polymer concentration on the release of fungicidal antimicrobial (AM) agent to prolonging the shelf life of packaged food. This project aimed to produce and test AM films with varying ...

The increasing rate of cancer patients worldwide, and especially Africa has led to numerous efforts to battle it. One approach to this has been localized drug delivery to reduce the quantity of drugs needed for therapeutic ...

This research focuses on the design of a robust but flexible prodigiosin eluting stent coating for possible coronary cardiovascular implant. When coated with the drug embedded polymer matrix, the stent would be expected ...

Bioinspired design involves the use of concepts observed in natural biological materials in engineering design. The hope is that the leveraging of biological materials in the engineering domain can lead to many technological ...

Epoxy, a thermosetting polymer due to its attractive properties, has been widely used in many industries as a coating material such as the oil and gas industries. This study provides an insight into the corrosion behavior ...

Conversion of lignocellulosic biomass from bamboo (Bambusa vulgaris) to butanol is an important alternative energy source. In this work, bamboo was used as biomass feedstock for the production of butanol by the fermentation ...

Wellbore instabilities are responsible for 10-20% of the total drilling cost. It has been estimated that wellbore instability causes an annual economic loss of US$ 500 - 1000 million in the oil industry across the world. ...

The corrosion behavior of uncoated and cut-back bitumen coated X65 Steel samples are being investigated in environments of different pH (2, 3, 4 and 7). Immersion tests were carried out on the samples at 25oC. The comparison ...
