Oil indications confirmed in Dover’s first Egyptian well target
Oilfield services company Schlumberger reported that Dover Petroleum’s first target well in Egypt contains trapped oil in the porous dolomites. Electric logs also indicate that the carbonate reservoirs are extensively fractured.
The fractures in Dover’s East Wadi Araba EWA- 2X well target are the cause of the loss of circulation and the major losses of water to the formation experienced while drilling. Such fractures will enhance the porosity and permeability of the carbonate reservoirs.
However, the single porosity log, which was able to be run in the well, only measures the matrix porosity and thus the resulting porosity determinations of 10 percent and 12 percent are probably too conservative. More porosity through fracturing could lead to more potential oil in the structures.
The two drill stem tests, which were carried out over the Kareem and Thebes zones only, recovered water from the drilling fluids, which were lost to the formation. No formation fluids were recovered during the tests, which were limited to one day for each of the intervals tested. Thus, the tests were not indicative of the reservoir's ability to flow oil or not because reservoir fluids were not produced, rather only fluids introduced during the drilling process.
Dover Petroleum is in further discussions with Schlumberger to extend their independent evaluation to include the results of testing, analyses of the fluids produced on the tests and to integrate these with the drilling history and the log results in a comprehensive study.
Dover's wholly owned subsidiary, Dover Petroleum Egypt I, has a 56.25 percent interest in Dover Egypt I Joint Venture, which is a party to an Option Agreement entitling that joint venture to acquire 100 percent of the Operator's interest in the East Wadi Araba Concession Agreement. — (menareport.com)
