The Frigg Field was discovered by well 25/1-1\r\nin 1971. Production from the field started in 1977. A main objective of well\r\n25/1-7 was to establish a reference monitoring station for the production of\r\ngas from the Frigg Field. The objective of the re-entry 25/1-7 R was to record\r\nthe fluid contacts. \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\u003eSemi-submersible installation Nortrym\r\narrived the 25/1-7 location on 8 February 1987.
