New Oil Tally for Rally in Egypt’s West Issaran

Rally has successfully completed drilling of the West Issaran No.1 exploratory well to a total depth of 2,552 feet.

The well was drilled to evaluate the potential of the three main Issaran producing formations, and according to the company, oil pay was encountered in two of the three formations.
Rally said that the well was drilled to test three formations of interest, the Nukhul, the Lower Dolomite, and the Upper Dolomite. All three zones were penetrated, however the deepest zone, the Nukhul, was tight and not hydrocarbon bearing.

At the Lower Dolomite level, the well encountered 120 feet of dolomite oil pay and in the Upper Dolomite drilling encountered 224 feet of potential net oil pay
The company said that there were excellent hydrocarbon shows encountered while drilling. Image logs did not reveal any significant fracturing present within this zone, indicating to management that the well had, in all probability, discovered another encouraging reservoir of thermally recoverable reserves. Testing of the well has commenced at the Lower Dolomite level and upon determination of results within 3-4 weeks, the well will be placed on production.
Based on existing 3-D seismic data, Rally initially anticipates two additional West Issaran wells will be drilled in the next several months to delineate the extent of the Upper and Lower Dolomite accumulations and to evaluate the ultimate reserves potential from thermal recovery methods.
