The consideration of pipe eccentricity and its impact on hole cleaning has not been widely reported in literature. Pipe eccentricity affects the average velocity of the drilling fluid in the annulus which is one of the ...

Pipes that make up oil and gas wells are not vertical but could be inclined at any angle between vertical and the horizontal which is a significant technology of modern drilling-Experimental data on time varying liquid ...

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 ...

Gas condensate reservoirs are initially discovered as single-phase gas reservoirs. As the reservoir is produced below the fluid dew-point pressure, an increase in condensate saturation in the near wellbore region occur ...

A new method for analysing productivity index (PI) on vertical wells is the main objective of this study. Well performance is often measured in terms of the well’s productivity which is dependent on a number of factors ...

New sources of energy should be found to relieve the high demand of energy. Even though heavy oil and bitumen are difficult to produce due to their high viscosity which can be reduced by heating, with increased oil price, ...

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 ...

Despite its numerous benefits the search and production of crude oil poses a lot of dangers to the environment. Among these include land, water and air pollution. Prominent among the major sources of E&P waste is drilling ...

The purpose of this work is to evaluate the uncertainty in the volumes of fluids in place in Fault Block A (Segment 3) of the G-1 Sands in the OND field located offshore Niger Delta. The evaluation was performed in three ...

Determination of optimal well locations for infill drilling is a challenging task because engineering and geologic variables affecting reservoir performance are often nonlinearly correlated and have some degree of uncertainty ...

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 ...

Worldwide awareness of thin-bedded reservoirs (including turbidites) has become increasingly important with about 30-40% of the world’s oil in-place resources confined within thin-bed laminated reservoirs (Tyagi et al. ...

One of the ways of maximizing recovery from a reservoir is by drilling infill wells. Infill well placement is challenging because many well scenarios must be evaluated when undertaking the optimization program and very ...

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 ...

The AK field is an oil field draining the Agbada Formation, one of the three units of the Niger Delta Province, which started forming about 50 million years ago. Reservoirs from the AK field are sandstones and are located ...

Formation of water-in-oil emulsions are among the major challenges encountered by production and surface facilities engineers during the recovery of crude oil, especially in a large multi-wells system in both onshore 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 ...

Enhanced oil recovery (EOR) using ethane gas or flue gas has proven to be successful in some regions of the world, but these methods have not been implemented in the Niger Delta. This work investigates the technical and ...
