Page 50 of 99 | August 2018 | 49 HYDRAULIC FRACTURING: TECHNOLOGY (no forklifts, limited exposure to silica dust). The system integrates with our inventory control processes and is seamlessly integrated into our operational software to enable direct implementation of job designs right from the sales contract. Perhaps most importantly, the Automated Stimulation Delivery Platform enables us to be more efficient with people on location, enabling us to grow faster as we free experienced personnel to start new frack crews." To enhance production, in 2018 Schlumberger OneStim began using the new WellWatcher Stim stimulation monitoring service to evaluate fluid placement in real time on frack jobs. The WellWatcher Stim service imports expertise in signal processing from seismic technology into the fracturing domain to extract information about subterranean situations from acoustic analyses of the observed pressure behav- ior of a well under treatment. "We have learned to extract information about which zones accept fluid, and we can also directly evaluate plug integrity and well integrity using this service," MacKay said. "This service can be coupled to our existing BroadBand Sequence fracturing service (near-field diversion) and BroadBand Shield frac- ture-geometry control service (far-field diversion) techniques to deliver state-of-the-art control over fracture geometry." These services, bundled together, represent a step- change in the tools available to control interwell interactions, or "frack hits," in infill drilling cam- paigns. Schlumberger has already been able to solve significant problems for operators facing challenges such as casing failures without needing to abandon significant portions of a horizontal wellbore using this approach. "Schlumberger's OneStim business line uses a new and potent set of tools for subterranean fracture engi- neering to assist our customers with design, detection and control of fracturing jobs," MacKay added. "The Kinetix Shale reservoir-centric stimulation-to-pro- duction software and Planar3D fracturing design simulator based on a planar 3-D model offer rapid results based on new achievements in computational efficiency based on improved algorithms and cloud computing. For Lonestar Resources Ltd. Kinetix Shale software helped increase production by up to 86% in the Eagle Ford Shale." Additional automation technology in the field of hydraulic fracturing is expected, but it is still early days for most. Whether it's an algorithm-driven workflow for selecting and designing frack stages or volumetric water and sand handling, industry is making strides toward introducing new automated components to fracking operations. However, these innovations are expected to be met with their own set of challenges. "I think the challenges for industry will be the technical complexity of the challenges we're trying to solve and boiling down a lot of complicated engi- neering into a single algorithm or something that is going to drive full automation," Halliburton's Gale The Automated Stimulation Delivery Platform automates and streamlines surface operations, resulting in a smaller footprint, sustained efficiencies and substantially reduced NPT.
