The first horizontal well to be drilled targeting the Ordovician Bir Ben Tartar Formation in the Ghadames Basin of Southern Tunisia was completed on July 1, 2012 with the rig release of the TT16 well.
The TT16 well is the first multi-stage, hydraulically fractured horizontal well in Tunisia. It is also the largest multi-stage job attempted by Schlumberger on the African continent. Despite the significant challenges associated with logistics, equipment, and manpower, the operation was completed successfully and represents a valid test of this recognized technology in a new application. The target reservoir on the BBT concession is a thick (up to 50 metres of pay column), low permeability (average close to one millidarcy permeability), heterogeneous clastic reservoir that demonstrates commercial flow rates from stimulated vertical wells. The application of horizontal wells in this low quality, conventional reservoir is an attempt to increase the rate per well and ultimate recovery relative to what can be achieved with fractured vertical wells.Sanoi Chinook
Kahden viikon päästä pitäisi olla kuukauden edestä testausta takana. Useimmiten tuollainen itsensä ja kumppanien onnittelu pelkän reijän rykäisystä on huono merkki tulevan kannalta. Tiedotteen mukaan poraus ja frakkus on onnistunut, joten testilukujen pitäisi antaa realistinen kuva kaivon potentiaalista.
