On the horizontal-well pumping tests in anisotropic confined aquifers [PDF]

Journal of Hydrology, 2001
A method that directly solves the boundary problem of flow to a horizontal-well in an anisotropic confined aquifer is provided. This method solves the point source problem first, and then integrates the point source solution along the horizontal well ...

Pseudo-Horizontal Well: Alternative to Horizontal and Vertical Wells

Proceedings of International Conference on Horizontal Well Technology, 1996
Abstract Horizontal wells are getting more and more widely used in oil and gas fields development due to plenty of its merits. However, there are examples when horizontal well drilling did not justify hopes. It is shown in this paper, that layered and anisotropic structure of the reservoir may lead to decrease of initial oil flow rates ...

Horizontal Wells – Are They Worth the Cost?

PetroVietnam, 1995
ABSTRACT Horizontal and extended-reach wells are making an important contribution to world's oil production. Well over five thousands horizontal wells and drainholes have been drilled, with approximately fifteen hundreds such wells in Canada.

Horizontal-Well Pressure Analysis

SPE Formation Evaluation, 1987
SummaryThis paper presents an analysis of the pressure-transient behavior of a horizontal well or a drainhole. The performances of horizontal wells and fully penetrating vertical fractures are compared. Dimensionless wellbore pressures are computed for two classic boundary conditions: infinite conductivity and uniform flux.

Thermal Well Testing For a Horizontal Well

Annual Technical Meeting, 1992
Abstract Horizontal wells are becoming popular for primary and enhanced oil recovery operations because of unique advantages of horizontal wells in comparison to those for vertical wells. Monitoring the progress of a steam injection process requires a knowledge of the steamswept volume, as this provides a measure of
