Water based mud was used down to 1080 m and an\r\nAncoVert oil based mud from 1080 to TD. Well 25/10-8 found the Heimdal Fm to be\r\nwater wet, the Upper Jurassic sands to contain gas and oil and the Middle\r\nJurassic and Rotliegendes sands to be water wet. A core was cut from 2080 -\r\n2107 m in the Heimdal Formation, a second core was cut from 2518 - 2546 m in\r\nCallovian Jurassic to Triassic sediments. After testing the well was plugged\r\nback to the 13 3/8" casing on 4 April 1997 as an oil and gas\r\ndiscovery. Sidetrack 25/10-8 A was\r\nkicked off from 1067 m and drilled to a total depth of 3460 m (2537 m TVD RKB)\r\nin Late Jurassic. An 8 1/2" hole was drilled to core point at 3110 m using\r\noil based mud. Three cores were cut in the Late Jurassic; 3110 to 3147 m, 3147\r\nto 3165 m , and 3165 to 3202 m. No wireline logs were run in well 25/10-8 A,\r\nonly MWD. No fluid samples were taken. All reservoir sands were found water wet\r\nand sidetrack 25/10-8 A was permanently abandoned as a dry well on 27 April\r\n1997.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 25/10-8 was perforated from 2391.4 -\r\n2398.4 m in the Upper Jurassic.
