Estimation of Drilling Wastes – an Environmental Concern While Drilling Oil and Gas Wells
(2011-10-20)
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 ...
Quantification of Uncertainty and Risks for Developing Marginal Fields in the Niger Delta
(2011-11-20)
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 ...
Effects of Partial Completion on Productivity Index
(2011-12-12)
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 ...
An Approach to Identifying the Optimal Time to Initiate Stimulation Operations.
(2011-11-20)
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 ...
Pressure Transient Analysis of Hydraulically Fractured Wells in Multilayered Reservoirs
(2011-12-20)
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 ...
Development of Generalized Well Semi-Analytical Coning Models
(2011-11-20)
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 ...
Temperature Prediction Model for Flowing Distribution in Wellbores and Pipelines
(2011-12-12)
Down-hole temperature and pressure data are important information needed to understand flowing conditions and production optimization. For example, knowing the wellbore temperature profile is useful in predicting the wax ...
Prediction of Surge and Swab Pressure Profile for Flow of Yield Power Law Drilling Fluid Model through Eccentric Annuli
(2011-12-12)
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 ...
Pressure Transient Analysis in Anisotropic Composite Reservoirs – A Three Dimensional Semi-Analytical Approach
(2011-12-20)
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 ...
Deepwater Petroleum Exploration and Production in the Gulf of Guinea: Comparative Analysis of Petroleum Fiscal Systems Performance
(2011-12-12)
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 ...
