Tethys Petroleum Limited is pleased to announce the success of Well AKK19, the third shallow gas exploration well of its 2014 programme. Analysis of data from the well indicates it has a pay zone twice as thick as the AKK15 well which tested gas at a stable rate of approximately 7 million ft3 (195 000 m3 or 1167 boepd, and the AKK19 well is anticipated to test at significantly more than that rate.
The AKK19 well was drilled to a depth of 800 m (2624 ft) some 5 km (3.1 miles) south-east of AKK15 and encountered an 8 m (26 ft) interval of gas bearing Tasaran sand with an average porosity of 30%. This compares favourably to the AKK15 well which encountered a 4 m (13.1 ft) gas-bearing interval of similar quality, and which will be tied in as part of this year's programme. The AKK19 well will now be cased and prepared for production testing later in the year in conjunction with the AKK17 and AKK18 wells in order to be cost effective with resources.
The current shallow gas programme includes the drilling of up to 10 new exploration wells, based on the latest seismic data, as well as workovers and tie-ins, and is targeting a three fold increase in gas production by the beginning of 2015.
Graham Wall, Chief Operating Officer of Tethys commented, "This is a very good result and log indications would suggest we could test the well significantly in excess of the flow achieved from the AKK15 well. We now have three successes from the first three wells in this year's shallow gas programme and continues to validate our geological model with further wells planned on similar targets in the vicinity."
Tethys is focused on oil and gas exploration and production activities in Central Asia and the Caspian Region. This highly prolific oil and gas area is rapidly developing and Tethys believes that significant potential exists in both exploration and in discovered deposits.
