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 ...
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 ...
Implications of Production Decline Patterns, Cost Depreciation Methods and Fiscal Regimes on Offshore Profitability in Nigeria
(2011-12-20)
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 ...
Modeling and Simulation of Reservoir Formation Damage due to Chemical Precipitation and Particulate Processes
(2011-11-20)
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 ...
Practical Approaches for Solving Lost Circulation Problems while Drilling
(2011-12-12)
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 ...
Evaluating Uncertainty in the Volumes of Fluids in Place in an Offshore Niger Delta Field
(2011-12-12)
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 ...
