We use the poroelastic signals to compute a simple, accurate, affordable pressure-based fracture map by matching the observed responses in the monitor well to a digital twin. The fracture map includes fracture half-length, height, asymmetry, and azimuth and how fast these dimensions grew.
With the fracture map and DiverterSCAN technology, we compare the largest fracture’s growth rate before and after the diverter drop so you can determine the success of a given design. A successful diversion design results in stopping or significantly slowing the fracture growth rate after the diverter drop. An unsuccessful diversion design results in the largest fracture continuing to grow post-diversion. The technology documents these two scenarios. With this information, you can determine which diversion design is best for the geology and completion.
With this information, our customers have realized a 10% to 30% increase in production on subsequent pads.
An operator working in the Stack/Scoop, wanted to test several diversion designs and evaluate which one would be right for ﬁeld-wide implementation.
Before the operator began fracking the well, we worked with the operator’s completion engineers to develop a comprehensive data acquisition plan that accounted for the planned fracking sequence and any field operations constraints, such as a zipper fracking manifold and the reach of overhead cranes. The data acquisition plan was included in the field operating guidelines. A real-time data stream was set up to transmit pumping data – pressure, rate, and proppant concentration – and offset wellhead pressure to our office.
Once fracking concluded on each stage, a team of our geoscientists and completion engineers finished the data processing and quickly analyzed the individual diverter drops. The team immediately let the operator know whether the diversion stopped or failed to stop the largest fracture growth in that stage. With all of these data, the operator could make an informed, better decision about the right diversion design
“We’re applying Reveal Energy Services’ DiverterSCAN technology to optimize our completions in a new and quicker manner. Within two hours, we received analysis that allowed us to evaluate the effectiveness of our diversion implementation while completing wells on one of our Stack/Scoop pads. With these quick results, we determined the most effective diversion design on the remaining stages, instead of relying on one unverified design for the entire completion.” Byron Cottingham, P.E.
