The evaluated gravel pack PoSD is then used to compute the filter efficiency of the pack for various formation sand sizes. Sand production through the gravel pack is predicted analytically by applying the filter efficiency data to any given formation PSD under the assumption that straining is the dominant sand-retention mechanism for a gravel pack.

Sand production is one of the problems that many operators have been dealing with. Sand production can occur based on high flow rates, stress regime, rock geomechanical properties, and completion design. The prediction of sand production is very important since it helps production engineers to come up with sand control strategies. Based on actual …

new pits are 300 feet apart. If all the test pits show sand and gravel, it is assumed that the entire area, 300 feet by 300 feet contains sand and gravel. Test pit E is excavated but no sand and gravel are found. This means the gravel deposit ends somewhere between B and E. It can be assumed the gravel material stops halfway, or in this case, 150

The sand failure pattern is found to largely differ from that of a sandstone reservoir, whereas fractures, wormholes, and fluidized channels are successively developed along with a large scale of sand production and inlet pressure variation. Followed is a steady flow state with a stable inlet pressure without noticeable sand failure.
