Gulfsands Petroleum, the oil and gas company with activities in Syria, Morocco, Tunisia and Colombia has confirmed a new shale gas discovery within the Rharb Centre Permit in Northern Morocco.
The Douar Ouled Balkhair 1 gas exploration well was cemented and perforated over the primary reservoir interval, completed and then subjected to a flow testing and pressure survey period for evaluation of well flow performance and connected gas volumes. The primary reservoir target interval on prognosis at a depth of approximately 808 metres MD.
During initial clean up flow operations over this reservoir, the well produced natural gas at an estimated rate in excess of 10 million standard cubic feet per day (“mmscfpd”) on a 48/64th inch choke setting. During subsequent multi-rate flow testing, a stable flow of 6.2 mmscfpd was established for a period of 4 hours on a 32/64th inch choke setting, with a final wellhead flowing pressure of 1084 psi. No formation water was detected in the gas production stream during testing operations.
The secondary reservoir target interval for the well was encountered at a depth of approximately 1075 metres MD. Significantly elevated gas readings were encountered over the interval 1075-1127 metres MD.
However, after the completion of wire line logging operations, mechanical problems with well bore integrity above this interval prevented further access to or production testing of this deeper potential reservoir.
The Company is currently reviewing all available data in order to determine the optimal path for further exploration of this reservoir section, which may include a re-deepening of this well at a later date post production of the shallower gas zone, potentially employing in this future operation a modified and strengthened well design.
Mahdi Sajjad, the Company’s CEO commented:
“We are delighted with the results of the drilling and flow testing operations at well DOB-1. This is the third consecutive successful exploration drilling result that the Company has achieved in Morocco utilising the 3D seismic data acquired and processed in 2013-2014.
We are continuing with our efforts to commence production from these discoveries and are receiving much appreciated assistance from ONHYM to ensure this is achieved as soon as possible”.
According to the Energy Information Agency (EIA) estimates, Morocco has untapped shale gas potential with 20 trillion cubic feet and 200 million barrels of technically recoverable shale gas and oil resources, respectively.
These resources include those located in the Western Sahara territory and are mostly located in the Tindouf basin, with smaller amounts in the Tadla basin.
