补救性防砂的挑战在于，系统必须通过上部完井的限制，才能理想地符合需要防砂的区域的内径 (ID)。完整的论文描述了多层开孔基质聚合物 (OCMP) 系统在海上气井中首次水平部署的资格。该系统能够通过紧密的油管限制进行补救部署，同时在水平井眼中提供一致的防砂，而无需砾石充填，这使得该方法对于表面空间有限的情况特别有价值。
2006 年，CH-20、CH-19 和 CH-18 气井最初在哥伦比亚近海 Chuchupa 油田的 B2 区钻探并完井。CH-20、CH-19 和 CH-18 气井分别于 2016 年末、2018 年和 2020 年从含水层中突破水流。
The challenge of remedial sand control lies in the fact that the system must pass through restrictions in the upper completion before ideally conforming to the inner diameter (ID) of the zone requiring sand control. The complete paper describes the qualification of a multilayer, open-cell matrix polymer (OCMP) system for the first horizontal deployment in an offshore gas well. The system is capable of being deployed remedially through tight tubing restrictions while providing conformant sand control in a horizontal wellbore without the need for gravel packing, making the approach particularly valuable for scenarios where surface space is limited.
During 2006, gas Wells CH-20, CH-19, and CH-18 were originally drilled and completed in the B2 zone in the Chuchupa field offshore Colombia. Wells CH-20, CH-19, and CH-18 experienced water breakthrough from the aquifer in late 2016, 2018, and 2020, respectively.
