Indonesia-focused Lion Energy Ltd. reported Friday that Lofin-2 appraisal well in Seram (Non-Bula) Production Sharing Contract (PSC) in eastern Indonesia has reached a depth of 19,229 feet (5,861 meters) measured depth (MD). Gas chromatography and oil shows in the primary objective were encountered through to total depth. Ongoing operational issues involving stuck drill string have resulted in the decision to test a 1,433 feet (437 meters) open hole section of the Manusela limestone.
Since Lion’s last update on the Lofin-2 well April 30, wireline logging to 17,949 feet (5,471 meters) MD and deepening of the 6 inch hole to the current total depth of 19,229 feet (5,861 meters) MD was completed, with gas and oil shows continuing to be encountered in the primary objective. Analysis of pressure data support an interpreted significant gas column in the large Lofin structure.
Lion’s CEO Kim Morrison noted “While it is clearly disappointing to have encountered the operational problems on Lofin-2, the results to date are highly encouraging and we look forward to the testing results.”
Lofin-2 Appraisal Well
The Lofin-‐2 appraisal well spud October 31, 2014. The well is being drilled to appraise the 2012 Lofin-1 discovery which flowed gas and some oil/condensate from the Manusela Formation. The well is operated by CITIC Seram Energy Ltd (51 percent) with other co-venturers being KUFPEC (Indonesia) Ltd. (30 percent) and Gulf Petroleum Investment Company (16.5 percent).
Lofin-2 had a planned total depth (TD) of 17,799 feet (5,425 meters) MD (17,457 feet or 5,321 meters total vertical depth referenced to sea level (ssTVD) with the primary objective Manusela Formation projected at 14,724 feet (4,488 meters) MD (14,383 feet or 4,384 meters ssTVD). The primary objective was intersected at 15,141 feet (4,615 meters) MD (14,790 feet or 4,508 meters ssTVD), some 410 feet (125 meters) deeper than prognosed. Wireline logging of the open-hole section above 17,949 feet (5,471 meters) MD (17,546 feet or 5,348 meters ssTVD), including pressure measurements, provide strong evidence that the hydrocarbon column continues deeper and therefore the well was drilled to a revised Total Depth of 19,229 feet (5,861 meters) MD (18,654 feet or 5,686 meters ssTVD). Encouraging gas and oil shows continued to be recorded while drilling through to the revised total depth within the Manusela limestone.
Since Lion’s last update on the Lofin-2 well April 30, wireline logging to 17,949 feet (5,471 meters) MD and deepening of the 6 inch hole in the Manusela limestone objective to the current total depth of 19,229 feet (5,861 meters) MD was completed. Analysis of pressures obtained on wireline, combined with pressures obtained in the Lofin 1 discovery well, support an interpreted significant gas column in the large Lofin structure.
On pulling out of hole the drill pipe became stuck and on attempting to pull free the drill pipe parted with the top of the stuck drill string at 16,486 feet (5,025 meters) MD (16,236 feet or 4,948 meters ssTVD). Numerous attempts to free the stuck pipe have been unsuccessful. Operation are currently focused on fixing a hydraulic problem with rig equipment. Once rectified the decision will be to test the open reservoir section of 1,434 feet (437 meters) above the stuck drill string. The test will confirm fluid content and flow potential of the Manusela down to the base of the tested section.
