在二叠纪盆地压裂作业中，对两口井中一次性分布式光纤记录的方位角和强度进行积分，并与通过介入光纤获得的返排后生产分配和干扰测试进行比较，以确定导水裂缝区域和偏移之间的通信井。即使在没有应变数据的情况下，生产分配/干扰测试方法似乎也能揭示水力连通的裂缝。
基于干预的光纤已被证明是了解压裂期间和返排后井和段性能的有价值且具有成本效益的工具。压裂期间诊断，例如来自偏移监测井的井间应变测量，描述了裂缝与监测井相交的位置，并揭示了方位角、裂缝扩展速度以及激活和再激活统计数据等细节。这些关键数据点有助于为集群、阶段和井距决策提供信息。
In Permian Basin fracturing operations, azimuths and intensities recorded by single-use distributed fiber optics in two wells are integrated and compared with post-flowback production-allocation and interference testing acquired with intervention fiber optics to identify areas of hydraulically conductive fractures and communication between offset wells. The production-allocation/interference testing method appears to reveal hydraulically connected fractures even in the absence of strain data.
Intervention-based fiber optics have proved a valuable and cost-effective tool in understanding during-fracturing and post-flowback well and section performance. During-fracturing diagnostics, such as crosswell strain measurements from an offset monitor well, describe where fractures intersect the monitor well and reveal details such as azimuth, fracture-propagation velocity, and activation and reactivation statistics. These critical data points help inform cluster, stage, and well-spacing decision-making.
