Real-time stimulation optimization software
Use surface and downhole data to facilitate immediate decisions during fracturing and acidizing operations.
WellWatcher Stim stimulation monitoring service improves hydraulic fracturing, acidizing, and other well operations by confirming downhole events in near-real time. With fast setup and a minimal location footprint, the service verifies events such as actuation ball landing, plug setting, port shifting, fluid entry into the reservoir, and fluid diversion.
Corrective measures (for example, reruns or additional ball drops) can be immediately implemented if required, saving time and money by avoiding later remediation operations and production losses.
During pumping, powerful high-frequency pressure pulses travel downhole. A downhole restriction, such as a fracture or change in tubing diameter, reflects part of the pulse energy back to the surface. WellWatcher Stim service uses proprietary algorithms and technology to analyze and visualize these returning pulses during stimulation treatments, detecting and verifying critical events such as interstage diversion, interstage isolation, and fracture hits in offset wells. The technology has been proved in wells up to 20,000-ft [6,100-m] MD.
Conventional methods of optimizing treatment designs monitor surface pressure trends to identify the occurrence or depth of downhole events. However, other factors such as slurry density, pump rate changes, and fluid transmissibility can also affect surface readings, influencing the accuracy of such techniques, especially in multistage fracturing operations.
WellWatcher Stim service is strongly recommended for exploration wells, where reservoir knowledge is limited and the stimulation strategy is unproven. By providing conclusive evidence of stimulation effectiveness for each zone, it enables you to fine tune your strategy and optimize production.
Abandon the cookie-cutter approach to restore efficiency, economics, and effectiveness to unconventional developments.
The increasing trend of drilling infill wells (more than 60% of new wells in 2017) comes with the significant risk of well interference.
Improve fracturing, acidizing, and other well operations via near-real-time confirmation of downhole events.
Minimize the risk of communicating with neighboring wells or fracturing into undesirable zones.
In two infill wells, WellWatcher Stim service sees frac hits in up to 61% of stages stimulated with conventional fracturing, North Dakota.
