Luna开发独特的高分辨率岩石应力测量概念
(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.
Businesses that rely on underground operations, such as the petroleum and geothermal industries, require accurate estimates of in-situ stress, which refers to the existing pressure that exists underground before a hole is drilled. This affects drilling, surveying, and fluid injection (hydraulic fracturing, water flooding, CO2 sequestration) as well as phenomena such as fault re-activation and induced seismicity.
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.
“这项新技术的发展 - 使用现有的Luna光纤传感器和我们的ODISI仪器 - 让石油和天然气行业评估否则不可估量的关键参数,”Scott Graeff说,Luna总裁兼首席执行官。“We greatly appreciate Shell GameChanger for its support as well as its expertise with use cases in the oil & gas industry. Together, we show how the industry’s toughest test, measurement, and analysis challenges can be tackled with ideas like CHISL.”
Luna.’s CHISL sensor integrates fiber optic sensors into a flexible hydraulic sleeve, which applies pressure to a borehole wall until small longitudinal fractures are formed. Unlike hydraulic fracturing, where fluid flows into the fractures and causes them to grow in length away from the borehole, CHISL does not allow the fluid to flow into the induced fractures.
“对原位应力的可靠估计对于石油和天然气行业的许多应用至关重要。例如,液压压裂在Shales中的成功大大取决于所产生的骨折高度,这又通过深度的应力变化强烈控制。壳牌的阿列克谢Savitski评论了Luna的技术将估计压力深度概况,以前所未有的解决方案评论,壳牌的Geomechanics主题专家。“最大水平应力是最不确定的地下特性之一,通常从其他数据推断出来。但是,CHISL将使这种不确定性显着减少,这对于评估故障重新激活和诱导地震性的风险至关重要。“
CHISL传感器将提供新的数据类型that can be leveraged to increase safety, production efficiency and optimization of future subsurface engineered systems. Future field operations using a ruggedized sensor could yield in-situ stress measurements for unprecedented lengths of boreholes and in less time than traditional hydraulic-fracturing techniques. Apart from the stress profiling of rock formations for planning of hydraulic fracturing, other applications include caprock integrity sensing for oil wells and optimized drilling of complex oil wells.
