Group Mutual Exclusion in Opportunistic Network
(2016-06-15)The Opportunistic network is an interesting development in the Mobile Ad hoc Network (MANET) environment. It has no end-to-end connectivity among nodes. Unlike MANETs, the nodes in Opportunistic network are independent on ...

Generic Animation Tool for Traffic Simulation
(2016-06-15)Traffic simulation has become one of the most used approaches for traffic analysis in support of the design and evaluation of traffic systems. Although traffic flow models have been applied for almost a century to describe, ...

Technological Considerations for Devs-Based System Control
(2016-06-15)System control has grown from manual control where humans sense the environment, analyse the result and determine control actions to semi-automated control. In semi-automated control sensing is done by sensing devices and ...

Effect of Pipe Eccentricity on Hole Cleaning and Wellbore Hydraulics
(2010-12-12)The consideration of pipe eccentricity and its impact on hole cleaning has not been widely reported in literature. Pipe eccentricity affects the average velocity of the drilling fluid in the annulus which is one of the ...

Comparative Analysis of Reserves Determination Techniques in Overpressured Gas Reservoirs
(2010-12-15)Conventional methods used in determining initial gas-in-place and reserves for a dry gas reservoir entails the use of P/z vs cumulative production data. In a normally pressured gas reservoir, the only important production ...

Practical Approach to Effective Sand Prediction, Control and Management
(2010-11-12)The production of formation sand is a problem associated with most oil deposits in the world. Major Sand production effects affect safety, well or field economics and continuous production. This has prompted the continued ...

Theoretical Analysis of Gravity-Controlled Waterfloods
(2009-12-15)The concept of dumpflooding is to flow water from a high pressure aquifer zone to a low pressure oil producing zone by natural force of gravity through a well connecting the two zones to enhance oil sweep into a producing ...

A Review of the Rheological Effects of Power Law Drilling Fluids on Cuttings Transportation in Non-Vertical Boreholes
(2009-12-15)Cuttings transportation during in non-vertical boreholes is necessary for oil and gas wells. Adequate cuttings removal from a well in drilling is critical for cost-effective drilling as high annular cuttings buildup often ...
-
Review of Application of Pressure Derivative Concept to Multirate Tests
(2009-12-15)Pressure build-up data in low permeability reservoirs take too long and are usually of poor quality. A pressure buildup test is perhaps the most widely performed transient test. In pressure buildup test, a well which has ...

A Case Study of Natural Flow and Tubing String Design for a Water Drive Reservoir
(2009-12-15)The design of natural flow and artificial lift tubing strings for the whole life of a water drive reservoir was carried out using data based on synthetic reservoir performance based on a material balance. The effects of ...

Pressure Analysis of a Well With an Inclined Hydraulic Fracture in a Naturally Fractured Reservoir
(2009-12-15)Hydraulic fracturing has been an effective technique to stimulate damaged wells or wells producing from low-permeability formation. It has been established that the orientation of a hydraulic fracture is perpendicular to ...

A Study of the Effect of Liquid Flow Rate, Pipe Size and Pipe Orientation on the Liquid Hold-Up Using Beggs and Brill Correlation
(2009-12-15)The effect of liquid flow rate, pipe size (diameter) and pipe orientation (inclination) on liquid hold-up was investigated. Liquid flow rate between 500 STB/day and 5000 STB/day was studied. An oil of 25 ̊API at an average ...
