Noreco has completed the first stage of appraisal drilling on Huntington discovery in block 22/14b in the UK Central North Sea.
Drillstem testing of two intervals within Paleocene Forties oil pay yielded maximum flow rates of 2,100 bbl/d and 5,208 bbl/d. An appraisal well targeting Jurassic Fulmar sands will commence shortly.
At Noreco-owned Huntington oil find located in Block 22/14b, which was discovered in June this year, appraisal drilling of the northwestern half of the Paleocene Forties oil accumulation has been completed. Drill-stem testing of two intervals within 101 vertical feet of oil bearing Paleocene Forties oil pay was conducted on the eighth (8th) appraisal well bore.
The first test was conducted across 20 feet of perforations from 9,982-10,002 feet measured depth close to the free water contact. Oil flowed from this first test at a maximum rate of 2,100 bbl/d through a 44/64th inch choke at 371 psi flowing pressure. The second test was conducted through 75 feet of perforations from 9,870-9,945 feet measured depth at the top of the reservoir interval.
The maximum oil flow recorded from this second test was 5,208 bbl/d of 44 degrees API oil through a 72/64 inch choke at 380 psi flowing pressure. No water or sand was recovered in either test.
Drilling operations will commence shortly on the next phase of appraisal drilling at Huntington. This single appraisal well bore will attempt to target the oil/water contact in the Jurassic Fulmar sands on the flank of the structure well below the elevation tested by the discovery well drilled in the second quarter. This well is expected to be completed in the first quarter of 2008.
