多重压裂水平井在初始返排后会遭受高碳氢化合物递减和含水率的影响。这种现象的部分原因是近场和远场断裂电导率损坏。重复压裂作业（酸或支撑剂）可以缓解这些问题，产生良好的清洁性能和稳定的石油回收趋势。完整的论文详细介绍了在 Wolfcamp A 地层中使用酸增产技术，在开创性的定制金属氧化物 (TMO) 纳米颗粒流体的帮助下，成功提高长期油井性能的试点。
用TMO纳米流体代替普通表面活性剂的原因是它能够在断裂相和岩石基质之间形成键合，克服普通表面活性剂所表现出的问题，并提供长期的生产维持。
Multifractured horizontal wells suffer from high hydrocarbon decline and water cuts after initial flowback. This behavior is in part because of near- and far-field-fracture conductivity damage. Refracturing operations (acid or proppant) can mitigate these problems, yielding a good cleanout performance and stable oil-recovery trends. The complete paper details a successful pilot to improve long-term well performance using acid stimulation aided by a pioneering tailored metal oxide (TMO) nanoparticle-based fluids in the Wolfcamp A formation.
The reason for replacing normal surfactants with the TMO nanofluid was its ability to create bonds between the fracture phase and rock matrix, overcome the problems normal surfactants demonstrate, and provide long-term production maintenance.
