Well 34/10-33 CR is the re-entry of well 34/10-33 C, which\r\nserved as a host well for the long-term production test 34/10-T-33 C. \u00A0In this\r\ntest the production logging tools failed and the bottom hole pressure recorders\r\nwere only partly functioning in the long-term production test. Furthermore, an\r\nunexpected increase in GOR occurred during the test, and this could not be\r\ninterpreted based on the available data. Therefore the programme for the\r\nre-entry included a new test from the same perforation interval. A further objective\r\nof the re-entry was to retrieve and read two pressure recorders that were left\r\nin the well 34/10-33 C after the test production. The mean reservoir pressure\r\nshould be estimated from these data. After testing the well bore would be\r\npermanently abandoned.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eAppraisal well 34/10-33C was re-entered\r\nwith the semi-submersible installation Deepsea Bergen on 24 February 1990. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe pressure recorders were retrieved,\r\nbut both had failed to work.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eNo cores were cut and no wire line fluid\r\nsamples were taken.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eAfter testing the well was permanently\r\nabandoned on 27 April 1990 as an oil and gas appraisal well.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eTesting\u003c/span\u003e\u003c/b\u003e\u003cspan lang=EN-GB\u003e \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThree drill stem tests were attempted\r\nfrom perforations in the interval 3448 to 3517 m (3347.3 to 3395.4 m TVD MSL).\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eDST 1 was not initiated due to technical\r\nreasons.\u003c/span\u003e",
