Luna Develops Unique High-Resolution Rock Stress Measurement Concept
(ROANOKE, VA) - Luna Innovations Inc. (NASDAQ: LUNA) today announced that, working in partnership with Shell’s GameChanger™ early-stage-technologies program, it has developed an innovative concept for measuring in-situ stresses in subsurface rock using its fiber optic sensing solutions. When deployed, this technique would provide critical measurements with unmatched consistency and depth resolution, allowing safer and more efficient well operations.
依赖地下业务（如石油和地热产品）的企业需要准确的原位应力估算，这是指在钻孔孔之前地下存在的现有压力。bobapp综合体育下载这影响钻井，测量和流体注入（液压压裂，水驱，CO2封存）以及现象，如故障再激活和诱导的地震性。
The new technology, Luna’s Continuous Horizontal In-situ Stress Logger (CHISL), uses Luna’s high-definition fiber optic sensing (HD-FOS) and ODiSI® product to obtain direct, high-resolution strain measurements of induced micro-fractures and borehole deformation. New algorithms then process the strain measurements at the borehole to estimate in-situ maximum and minimum horizontal stress and their orientations.
“The development of this new technology - using existing Luna fiber optic sensors and our ODiSI instrument - lets the oil & gas industry assess critical parameters that have otherwise been unmeasurable,” said Scott Graeff,President and Chief Executive Officer of Luna.“我们非常感谢Shell Gamechanger的支持以及石油和天然气行业用例的专业知识。在一起，我们展示了行业最艰难的测试，测量和分析挑战如何与智商这样的想法进行解决。“
Luna的ChiSl传感器将光纤传感器集成到柔性液压套筒中，该液压套筒将压力施加到钻孔壁，直到形成小的纵向骨折。与液压压裂不同，其中流体流入裂缝并导致它们远离钻孔的长度，ChISL不允许流体流入诱导的骨折。
“A reliable estimate of in-situ stress is critical for many applications in oil and gas industry. For example, the success of hydraulic fracturing in shales greatly depends on the created fracture height, which in turn is strongly controlled by the stress variations with depth. Luna’s technology would allow stress depth profiles to be estimated with unprecedented resolution,” commented Alexei Savitski, Geomechanics Subject Matter Expert at Shell. “The maximum horizontal stress is one of the most uncertain subsurface properties and is usually inferred from other data. But CHISL would allow this uncertainty to be reduced significantly, which is critical for assessing the risks of fault re-activation and induced seismicity.”
CHISL传感器将提供新型数据，可以利用，以提高未来地下工程系统的安全性，生产效率和优化。使用粗糙化传感器的未来现场操作可以为前所未有的钻孔长度和比传统的液压压裂技术更少的时间产生原位应力测量。除了岩层的应力分析外，还为液压压裂规划，其他应用包括石油井的完整性感测，以及复杂油井的优化钻孔。
