The\r\nobjective of the re-entry was an elaborate testing program to obtain a number\r\nof reservoir engineering parameters.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 31/6-8 re-entered (31/6-8 R) on 22\r\nJuly 1985 with the semi-submersible installation Treasure Seeker. The well was\r\ntested without significant technical problems. Operations took 63 days. After\r\ntesting the well was plugged and permanently abandoned on 22 September 1985 as\r\na gas and oil appraisal.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eVarious tests were performed, including a\r\nproduction test, a sand production test, and fracture testing. Test 1 was a\r\nproduction test from the interval 1537.6 m to 1557.6 m as a high-rate test on a\r\nspecial production string. The test produced through gravel pack at maximum\r\n3900000 Sm3 gas /day on a double 2" choke, which was considered a world\r\nrecord for an offshore well. The liquid production at this rate was ca 105 Sm3,\r\ngiving a gas/liquid rate of ca 137000 Sm3/Sm3. The maximum temperature during\r\nthis test, from a gauge at 1528 m, was 68.5 deg.
