Artificial Neural Network for Diagnosis & Mitigation of Water Production
(2016-06-12)
From the inception of the oil and gas industry, water production has always been an aching problem for various operators. Throughout the productive life of a field, oil production is often accompanied with some amount of ...
Analysis of Void Fraction Phase Distribution of Gas-Liquid Flow In a Horizontal Pipe Using Wire Mesh Sensor Data
(2014-12-15)
The scope of this work was to make detailed analysis of phase distribution in a horizontal pipe. This detailed analysis has been successfully carried out. Data obtained from wire mesh sensor (WMS) were used for the analyses. ...
Effect of Linear Drift on Radial Transport of Tracer in Homogeneous Porous Media
(2014-12-12)
Analytical models can be valuable tools to investigate solute transport in porous media. The application of analytical solutions is limited by the perception that they are too cumbersome to derive while their implementation ...
An Experimental Model to Predict and Control Oilfield Emulsion Tightness: a Novel Approach
(2010-12-12)
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 ...
Optimization of Strategies for Natural Gas Utilization: Case Study of the Niger Delta
(2010-12-12)
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 ...
Prevention of Hydrates in Pipelines using Hybrid Thermodynamic Inhibitors
(2010-12-12)
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. ...
Combined Effect of Rheological Model and Equivalent Diameter Definitions on Pressure Losses/Equivalent Circulating Density Estimation
(2011-12-12)
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 ...
Development of a Computer Program for Solids Control
(2011-12-15)
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 ...
Building and Ranking of Geostatistical Petroleum Reservoir Models
(2010-12-12)
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 ...
Graphical Evaluation of Cuttings Transport in Deviated Wells using Bingham Plastic Fluid Model
(2011-11-23)
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 ...
