Abstract:

A gauge carrier which is tubing conveyed with a wireline retrievable gauge system for more effectively evaluating reservoir potential and whether it is economically feasible to complete the well and place it into production. The gauge carrier and method of this invention provides effective solutions to problems which arise when endeavoring to measure and accurately record bottom hole pressure during temporary flow tests as well as on a permanent hookup on a well completion. The gauge carrier can be run on the tubing or drillstem above or below a packer as a part of a temporary or permanent completion and the gauge assembly can be retrieved by the use of a wireline after the well completion process has been completed. The gauge carrier provides a support structure for mechanical or electronic gauges utilizing components which are readily available or easily constructed to enable the measuring gauges to be retrieved, checked and easily run back into the gauge carrier if additional information is required at any time during flowing and/or shut-in conditions.
