This research describes the application of a production economic approach which attempts to quantity stimulation treatments performed on different wells undergoing a decline phase in their production and to obtain based ...

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 ...

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 ...

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 ...

Oil deposits are often found in association with a communicating gas or water zone. The production of the oil often leads to the coning of water or gas. This dynamic interaction can be captured by a properly detailed ...

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 ...

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 ...

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 ...

Upstream petroleum industry remains one of the most prolific industries in terms of technology and risk capital transfer. Consequently, governments all over the world try to formulate political as well as economic structures ...

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 ...

One of the major challenges in reservoir engineering is the accurate description of the reservoir. This description is essential in all aspects of petroleum engineering, and is typically achieved through reservoir ...

Formation damage is an undesirable operational and economic problem that can occur in many phases of field development including drilling, completion, workover, production, stimulation, waterflooding and enhanced oil ...

Formation damage is an undesirable operational and economic problem that can occur in many phases of field development including drilling, completion, workover, production, stimulation, waterflooding and enhanced oil ...

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 ...

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 ...

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 ...

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 ...

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 ...
