据哈特能源10月9日消息，10月8日，哈里伯顿公司获得了埃克森美孚非水相流体砾石充填(NAFPac)技术的国际许可，该技术将用于埃克森美孚公司的砾石充填完井。
井眼稳定性和页岩抑制是裸眼完井成功安装的关键。通常选择NAF来优化钻井工艺，但在进行筛分作业之前将钻井液置换到盐水中，可能会出现井眼稳定性问题。
NAFPac工艺是一种砾石充填技术，该技术可使作业者在NAF中进行砾石充填筛管、砾石充填井，然后将套管置换至完井盐水中，整个过程只需一次作业。在NAF中运行筛管可以显著提高筛管安装成功和砾石充填完成的概率。
哈里伯顿完井工程副总裁Mark Dawson表示：“作为全球完井的领导者，哈里伯顿很高兴与埃克森美孚合作，扩大NAFPac解决方案在客户中的使用，帮助他们实现资产价值的最大化，这一现场验证技术进一步加强了我们领先的防砂组合技术。”

Halliburton Wins License To Run Exxon Mobil’s Open Hole Completion Technique
Halliburton has been awarded an international license for ExxonMobil’s patented Non-Aqueous Fluid Gravel Packing (NAFPac) technique for gravel pack completions on Oct. 8.
Hole stability and shale inhibition are keys to successful installation of open-hole completions. NAF is often selected to optimize the drilling process, but hole stability issues can occur when displacement to brine is done prior to screen running operations.
The NAFPac process is a gravel packing technique that enables an operator to run the gravel-pack screens in NAF, gravel pack the well, and then subsequently displace the casing to completion brine, all in a single trip. Running the screens in NAF significantly increases the probability of successful screen installation and a complete gravel pack.
“As the global completions leader, Halliburton is pleased to collaborate with ExxonMobil to expand the use of the NAFPac solution to our customer base to help them maximize asset value,” Mark Dawson, vice president of Completion Tools for Halliburton, said. “This field proven technique further enhances our leading sand control portfolio."
