.... The principle of superposition will be used in order to obtain a solution to the problem of interference testing of an active horizontal well in the presence of an active vertical well. The principle of superposition allows calculations of pressure drop created by horizontal well at that location...

... of images formed due to the inclination and dimensionless well design affect the dimensionless pressure gradients and their derivatives. For n images, shortly after very early time for each inclination, dimensionless pressure gradients of 1.151(N+1)/L D for the horizontal well and 1.151(N+1) for vertical...

... Abstract At inception of a production rate regime, a horizontal well is expected to sweep oil within its drainage radius until the flow transients are interrupted by an external boundary or an impermeable heterogeneity. If the interruption is an impermeable heterogeneity or sealing fault...

Mathematical procedure employed is based on selection of relevant source and Green’s functions for a horizontal well during infinite...

... Abstract Horizontal wells have become increasingly important in the development of oil and gas fields due to their added advantages such as increased offtake rates, high drainage areas, and reduced pressure drawdowns. However, many horizontal wells experience rapid production decline due...

... Abstract Horizontal wells are susceptible to early water breakthrough (EWBT) due to reservoir heterogeneity and "the heel-toe effect", caused by frictional pressure losses along the well that lead to a non-uniform production profile. Also, with heavy oil reservoirs, early water breakthrough can...

This novel work presents the pressure behavior of horizontal wells with non-Newtonian fluid flow in porous media as well as the methodology for analyzing pressure transient data from non-Newtonian reservoirs. The main...

... Abstract In this paper one of the areas of conflicts observed with the performance of horizontal wells standoff with respect to development of thin oil rim reservoirs is examined. In a technical paper as part of the critical review of literature on the exploitation of thin oil rim reservoirs...

... Abstract The job of pressure testing the tubing while running in a well was left up to running a standing valve to a nipple profile with a slick line unit. This involved multiple runs to set, test, and pull the standing valves, and with the advent of horizontal well's completion, the completion...

... Abstract The use of inflow control devices (ICD) have been used to balance flux around wellbores and also delay breakthrough of unwanted fluid into completions.1-2. Inflow-control devices (ICDs) were developed to avoid coning problems in long horizontal wells. The model for the ICD consists...

... Abstract Oil rim reservoirs are often troublesome to produce commercially as a result of the adverse effect of coning and cusping/cresting. In this study, deviated and horizontal wells were employed to determine the optimal well type to be drilled in the "GISO" oil rim reservoir in order...
