In early December 2019, Petrosilah Petroleum Co successfully tested the development well Silah 1-4 at the Silah field, Silah (Dev) block, Gindi Basin. The well, which was spudded on 25 October 2019 and drilled to a TD of 2,160 m encountered oil in two Cenomanian intervals: a 8-ft net oil pay in the G Member of the Abu Roash Formation and a 28-ft net oil pay in the Upper Member of the Bahariya Formation. The well is expected to come onstream rapidly.  The Silah field was discovered in September 2008 after the new field wildcat Silah 1 encountered oil in the Abu Roash G and Upper Bahariya members at depths between 1,500 and 2,200 m. The field was brought onstream in September 2009 and further developed until June 2011. Production improved recovery started in early 2014 with the commissioning of the first water injector Silah 02P-WI1.  Petrosilah Petroleum Co, a JV between EGPC (50%) and Merlon Petroleum El Fayum Co (50%) operates the Silah (Dev) block since May 2010.
