Australia-based oil and gas company Cooper Energy has completed the reservoir section of Sole-3 production well located offshore Australia with preparations now underway for flow back.
Cooper spudded the Sole-3 well located in VIC/L32 Gippsland Basin, offshore Victoria at the beginning of May by the Diamond Offshore-owned Ocean Monarch drill rig.
On May 31 Cooper Energy said that activities to complete the reservoir section of Sole-3 had started, with the well having been drilled to total depth (TD) and intersected reservoir and recorded gas observations consistent with the pre-drill expectation.
Come Tuesday, June 12 and Cooper completed the 97 meter near-horizontal reservoir section of the well. Cooper said that the production string is being installed and testing and preparations will soon start for well flow back.
It is expected Sole-3 will be ready for flow back within five to seven days. This is approximately one week later than previously anticipated due to operational issues associated with the downhole service tool.
The Sole-3 reservoir section has been completed using a standalone screen design without the gravel pack. The sand screens installed in the well are specifically designed and engineered based on test results to provide an effective screen of the Top Latrobe Group sandstone reservoir. This completion is expected to have inflow performance equivalent to the original design.
After the clean-up and flow of Sole-3, the drilling rig will be moved to Sole-4 which is some 40 meters away to resume drilling and completion of that well.
Sole-4 has already been drilled to a depth of 532 mMDRT (metres measured depth below rotary table) in the Gippsland Limestone, with 13 3/8” casing installed and cemented in place and the Sole-4 wellhead has been installed and tested.
