Tethys Petroleum Limited updated on its oil production activities at the North Urtabulak field in Uzbekistan. Tethys announced that it has now tested and put on production the newly drilled NUR116 well at the North Urtabulak Field in Uzbekistan with a test rate of some 610 barrels of oil per day (bopd) after acidisation.
The well was drilled to a total depth of 2,484 metres (8,150 feet) into the Jurassic reef carbonate reservoir. With production from this well current gross production from the North Urtabulak attributable to Tethys' Production Enhancement Contract would be over 2,000 bopd. One of the issues on the field at present is reduced gas lift pressure which is resulting in lower production rates than should be obtained. This issue is currently being addressed. A full field reservoir simulation model is currently being finalised which should give a better understanding of how to extract the remaining reserves from this field. Obtaining the pressure data for this reservoir model has resulted in several producing wells on the field being shut-in to gather these data but this will result in a more effective development of the field in the future.
Graham Wall, Chief Operating Officer of Tethys Petroleum commented: "We are pleased that we have completed this well and successfully tested it at a solid rate. Over the past few days it has tested at rates varying between 403 and 610 barrels of oil per day, in part due to fluctuating gas lift supply pressure. We will conduct further tests over the next week but this initial rate is encouraging and we have already begun to accumulate commercial production from the well for this month. We are about to commence our radial drilling programme on other selected wells on the field, which is expected to further increase production in the near future."
