... was performed to simulate the LF-DAS response to fracture propagation with embedded distributed optical fiber strain sensors under these conditions. The objectives of this research are to generate two hydraulic fractures of known geometry, measure the strain response along distributed fiber sensors embedded...

... by overcoming the requirement to install additional costly detection components. The unique sensor probe employs a circumferential array design, comprised of up to 512 individual elements which are electronically controlled from advanced imaging software. The integration of machine vision algorithms has led...

... Abstract This study discusses sensor-based, real-time detection and monitoring of emissions generated at a wellsite during a hydraulic fracturing treatment. The sensors recorded live data, which was visualized on dashboards and generated alarms whenever the threshold levels were reached beyond...

... been developed to embed a pressure sensor in existing hardware that is used in standard fracturing operations. This reduces operational complexity and enables gathering of critical bottomhole measurements including pressure and temperature as a function of time. This case study will address design...

..., along with sensitivity to 'stick and slip' effects on toolstring motion. Both technologies are also affected to differing degrees by the well fluid and the presence of diverters and proppant in perforations. The recent introduction of a toolstring able to simultaneously acquire images from both sensor...

... Abstract Low-frequency distributed acoustic strain-rate sensors (LF-DAS) experience strain changes due to far-field fracture propagation. To better understand the LF-DAS response to fracture propagation, we performed laboratory-scale hydraulic fracture experiments with embedded optical strain...

.... To monitor the effectiveness of mitigation after pre-loading, the team placed wellhead pressure sensors on pre-loaded primary wells, and primary wells in the adjacent pad. Sensors were installed on select vertical wells perforated through the target zones. In addition, wirelessy connected, high-pressure...
