Halliburton’s integrated sensor diagnostics service combines far-field and near-wellbore sensors with proven engineering practices to solve your unconventional challenges.
Well and fracture spacing are two subsurface challenges that have the largest impact on net present value in large-scale field development of unconventional wells. Pinnacle’s integrated sensor diagnostics service overcomes these challenges and more using customized sensors and engineering strategies. Our service delivers subsurface insight to help you make financially important decisions relating to well spacing, fracture spacing and stimulation design, based on characteristics of the reservoir and your needs.
Purpose-driven sensor acquisition drives engineering value to drastically reduce the learning curve surrounding pad and asset optimization. The far-field monitoring sensors that comprise the integrated sensor diagnostics suite include FracTrac? down hole micro seismic, surface microseismic imaging and FracNetSM micro deformation monitoring, while the near-wellbore sensors consist of Fiber Watch? distributed optical sensing and pressure gauges.
Pinnacle’s unique approach combines subsurface insight from far-field and near-wellbore sensors collected throughout the life of a pad, from completion to stimulation to production. This knowledge is then integrated with proven fracture and reservoir engineering techniques to address the challenges.
Optimizing Well Spacing
Halliburton has developed tools to improve confidence in selecting well spacing strategies and to quantify the impact of well spacing on your development goals.
Integrating near-wellbore and far-field downhole sensors, such as fiber optic monitoring and microseismic mapping, provides the ability to quantify the impact of completion and fracture design on well spacing. Through our integrated service diagnostics suite, the subsurface insight gained from these sensors is combined with fracture and reservoir modeling to define a roadmap for improving pad development for optimum well spacing.
Optimizing Fracture Spacing
Halliburton’s integrated sensor diagnostics suite helps define the best approach for optimizing fracture and completion strategies to improve fracture spacing. Fiber optic analysis has proven to be the go-to sensor for identifying fracture fluid placement by stage. Through integrated sensor diagnostics, this analysis is combined with production decline per stage and is used to calibrate fracture and reservoir models in order to develop a focused effort on optimizing fracture spacing.
Optimizing Completion Design
The Halliburton integrated sensor diagnostic suite utilizes both near wellbore and far field sensing to determine completion effectiveness. The impact as a result of completion design can then be quantified using proven engineering practices such as fracture and reservoir modeling. Cluster efficiency, isolation effectiveness and fluid placement all drive well productivity. Capturing and improving completion design effectiveness is a key benefit to the ISD approach.
Every shale formation is different, to some degree. Optimizing the asset can be a complex undertaking that involves understanding and integrating a vast scope of data to form a unified picture of the asset, from early planning through exploration and development to long-term production.

Near Wellbore Sensors
FiberWatch Distributed Optical Sensing
FiberWatch? sensing centers around distributed temperature and acoustic sensing results. These data provide real-time results during the fracture treatment to determine cluster efficiency, fluid distribution, and completion effectiveness. These are valuable inputs for the calibrated fracture model.
Pressure Gauges
Downhole pressure sensors are important for understanding fluid movement in a wellbore and fracture fluid movement between wells. Their value to integrated sensor diagnostics is tied to accurate bottom hole pressure results during well production.
Far Field Sensors
FracTrac Downhole Microseismic
Pinnacle pioneered this fracture mapping technology. The results from microseismic determine fracture geometry, azimuth, and fracture complexity. This is crucial to the integrated diagnostic solution as it provides critical inputs for the calibrated hydraulic fracture model.
Surface Microseismic Imaging
Pinnacle offers surface imaging to complement the down hole microseismic solution. The results again provide valuable fracture geometry information used to constrain the hydraulic fracture model. The far field geometry is critical for integrated sensor diagnostics.
FracHeightSM Microdeformation Monitoring
This tool combines the sensitivity of Pinnacle’s patented downhole tiltmeter sensors with downhole microseismic receivers conveyed on a fiber optic wireline. This hybrid tool array provides insight on actual fracture deformation as a function of depth. The focus for fracture geometry is on accurate hydraulic fracture height.
FracNetSM Microdeformation Monitoring
The FracNetSM monitoring solution is a deformation based solution developed to better understand fracture geometry. The patented technology provides clarity around fracture azimuth, orientation, and complexity; all of which are important for integrated sensor diagnostics.
Integrated Sensor Diagnostics Workflow
Project Setup
Understanding the project objectives is the first critical step to successful integrated sensor diagnostic implementation. To meet these objectives, ISD lays out a plan that places the correct sensors in the optimum locations and aligns the results with the correct engineering tactics.
Real-time Stimulation Analysis
Real-time stimulation diagnostics is a staple within Pinnacle’s core business expertise. Near well-bore fluid distribution and far-field fracture geometry form the framework for integrated sensor diagnostics.
Calibrated Fracture Modeling
Performing calibrated fracture modeling based on the fracture geometry and fluid distribution is the best method to take results indicating fluid placement, and turn that into proppant placement. Pinnacle professionals perform this step to further constrain the calibrated reservoir model and have more confidence in the end result.
Production Analysis
Production analysis is the step that makes the critical leap between fracture interpretation and the final reservoir interpretation. This analysis is performed through Pinnacle’s professionals using the distributed fiber-optic data throughout the well life.
Calibrated Reservoir Modeling
Reservoir modeling is performed by Pinnacle’s professionals on the complete project using the results acquired during injection through production. Once all this data is compiled, a final calibrated reservoir model is generated.
Asset Optimization
The final step of integrated sensor diagnostics ties all these pieces together. Pinnacle, along with the operator, can now go back and assess the project objectives and answer those most pressing questions. Pinnacle professionals will deliver engineering-based optimization recommendations built on this complete process.
Stage to Well
Real-time analysis and adjustments can be made on a per stage basis. These lessons can be applied throughout the entire well stimulation process, with the end goal of improving well performance. Integrated sensor diagnostics has a large, focused goal of asset optimization that begins during the very first stage. These include diversion effectiveness and completion effectiveness.
Well to Pad
Significant improvements can be made with each well analyzed using integrated sensor diagnostics. These real-time results are studied and analyzed by Pinnacle professionals and immediate lessons from the well applied to the remainder of pad operations. These include perforation cluster efficiency and stimulation design optimization.
Pad to Field
The end of the stimulation operations for a pad is quickly followed by the acquisition and analysis of production data. These lessons, when tied into the fracture and reservoir modeling results, produce asset optimization recommendations that can be applied throughout the entire field. These include stage spacing and lateral well spacing designs.
