Without accurate estimation of annular pressure losses it is possible to face serious problems that would yield to interruption in drilling operation and sometimes lead to the abandonment of the well. Therefore, exact ...

The Niger Delta is Nigeria’s and Africa’s most prolific producing basin and has some untapped oil resources because of their marginality. The development of marginal oil field in Nigeria has now become an important strategic ...

This research work mainly investigates the development and the behavior of cones (both water and gas cones) in oil reservoirs supported by strong aquifer, and from which analytical correlations are developed for quick ...

Computer software is used extensively to increase productivity and reduce man's hours of labour. This work presents the development of a solids control software (SOLCON) which is designed for real time mud system management ...

The transportation of cuttings and efficient hole cleaning are indispensible in any drilling program. This is because a successful drilling operation is the key to a profitable business in the oil and gas sector. A successful ...

Petroleum Fiscal System (PFS) is a major determinant of investment decision in the exploration and production of oil and gas in any country. It basically describes the profitability relationship between the host government ...

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 ...

As reservoirs become more complex and drilling operations more expensive, the need to reduce both inefficiencies and costs for constructing and analyzing high quality static models is essential. The effective and efficient ...

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 ...

Waterflooding is one of the most common secondary recovery mechanisms available for improving oil recovery from known accumulations. Due to the limitation of available water for injection, there's a need to optimize the ...

Reservoir characterization has long been identified as the ultimate process employed in detailed description of a reservoir in order to properly book the reserve and also to optimally place the wells and drain the reservoir. ...

Techniques in Geostatistics are increasingly being used to generate reservoir models and quantify uncertainty in reservoir properties. This is achieved through the construction of multiple realizations to capture the ...

Nigeria is endowed with huge proven gas reserves estimated to be 184 trillion cubic feet (Tcf). It ranks as the 7th holder of natural gas reserves in the world, and the largest in Africa. Nigeria also flares more natural ...

Appropriate selection of rheological models is important for hydraulic calculations of pressure loss prediction and hole cleaning efficiency of drilling fluids. Power law, Bingham-Plastic Herschel-Bulkley models are the ...

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. ...

The research is aimed at the understanding of the various diagnostic plots for the analysis of water production that are available as well as the application of these methods in a case study. It also aimed at the establishment ...

Maximum production from an oil well can be achieved through proper selection of tubing size. The selection of optimum tubing size must be evaluated when completing a well in any type of reservoir especially solution gas ...

The practical application of various production parameters and relations to predict the well performance analysis of a solution gas drive reservoir is the primary objective of this study. These parameters include: IPR ...

Well stimulation consists of several methods used for enhancing the natural producing ability of the reservoir when production rate declines. A de tailed literature review of some of the well published stimulation models ...
