Good Engineering Practices Achieve a 30-Fold Increase in Injection Rates in Selected Niger Delta Reservoirs

Horizontal Screen Failures in Unconsolidated, High-Permeability Sandstone Reservoirs: Reversing the Trend

“…Key points of successful implementation of pressure maintenance scheme by water flooding has been examined in a separate paper. 11 Another factor, which has been found to promote screen collapse, is premature bridging. This often occurs in high rate water pack or gravel packing operations, opposite a thief zone where a sand dune continues to be built up during transport due to rapid fluid loss until the velocity in the annulus increases to the critical settling velocity of the solid gravel particles in the carrier fluid.…”
