The Significance of Early Time Data in Interference Testing for Linear Boundary Dectection

PDF Version Also Available for Download.

Description

This paper considers the significance of early time data for detecting linear boundaries using interference testing. When the ratio r{sub 2}/r{sub 1} is greater than 5, existing methods of analysis may be used. For ratios of r{sub 2}/r{sub 1} smaller than 5, special considerations are needed. When the ratio of r{sub 2}/r{sub 1} is smaller than 2, there is no significant indication of the presence of a linear boundary in the pressure response. The effects of missing pressure data during the early time flow period, and earth tides on the linear boundary analysis are described and demonstrated with a flow ... continued below

The effects of missing pressure data during the early time flow period, and earth tides on the linear boundary analysis are described and demonstrated with a flow test in the Ohaaki geothermal field in New Zealand.
