Abstract
The West Delta Deep Marine (WDDM) fields are a Pliocene gas fields located in offshore Nile Delta, approximately 120km North-East of Alexandria, Egypt. These fields are comprised of sandstone reservoirs which are dominated by unconsolidated sandstone.
Sand production has become one of the main issues in WDDM since the discovery of a hole in the body of a liquid outlet valve from the onshore slug catcher. On further inspection, it was discovered that the hole had developed due to the presence of sand/fines causing erosion at the interface in the liquid handling system. Scarab-Saffron field was the primary source of sand production in WDDM with screen failure as the cause of the problem.
This paper details a method for determining maximum safe production rates for sand control wells. This method was developed from a thorough compilation of data from around 51 sand control wells. As a result of this analysis, a simple function of screen erosion limit has proved to be very reliable at identifying wells operating safely from those resulting in damaged screens or unacceptable amounts of produced sand.
