Create Uniform Fractures That Improve Well Productivity
Your goal is to get the most out of every cluster across each stage, but initial production rates may have you questioning your fracture treatment – and its ability to stimulate the reservoir effectively.
Well productivity depends on the number of effective fractures that are created and connected to the wellbore. However, many factors – such as stress orientation, heterogeneity, natural fractures, and completion design – can affect how evenly and effectively fractures propagate.
From stage spacing to an increased number of clusters, you have fine-tuned the optimal completion combination to mitigate downside risk and achieve profitable results, only to discover that all fracture treatments are not created equally – and, too often, they are not pumped as designed. When faced with stress shadowing, even well interference, the performance of a fracture treatment can be compromised – resulting in screenouts, uneven fracture growth, and, ultimately, limited well productivity.
If you want to drain the reservoir as completely and consistently as possible, then it’s time to get even – with automated stimulation services and leading completion technologies that optimize cluster efficiency by evenly distributing proppant and fluid across each stage, well to well, pad to pad.
Automated stimulation for consistent fracture treatments
The first few minutes of the stimulation treatment, when the fluid first interacts with the reservoir, are critical in establishing fracture geometry behavior for the remainder of the job. To establish an ideal behavior, the Prodigi™ intelligent fracturing service provides an automated stimulation treatment that controls pump rate breakdown for a more consistent fracture treatment.
At first glance, getting to treatment pressure may appear like a rudimentary process, but inconsistencies can often lead to costly screenouts, unnecessary well cleanups, and lost reserves. Using proprietary algorithms that are grounded on the engineering principles of fluid flow during limited-entry stimulation, Prodigi dynamically adjusts rate step amplitude and timing, based on the instantaneous pressure response of the reservoir. With these parameters, Prodigi determines the most optimal configuration for pumps to engage in, and then disseminates automated equipment commands within milliseconds.
By applying adaptive rate control, Prodigi promotes a more consistent and efficient breakdown of each perforation cluster for improved fracture connectivity and stage-to-stage performance.
On multiple pads and wells, in both the Marcellus and Utica shale plays, Prodigi has shown to provide an improvement in treatment consistency (15 to 35% improvement in treating pressure variation), as well as a reduction in treatment pressures (up to 10%). A 20% improvement in normalized production against comparable offsets, either on the same pad or offset pads, has also been realized.
Quantify cluster efficiency in real time
Wouldn’t you like to validate and compare which completion strategies worked best? With the permanent installation of our StimWatch® distributed fiber optic service, Prodigi provides a uniformity index that quantifies cluster efficiency in real time. Using distributed acoustic sensing (DAS), StimWatch measures proppant distribution per cluster while pumping, giving you the insight to validate the level of performance achieved, and to compare completion strategies and their effectiveness.
With Prodigi, you can get the data, make the decisions, and take the actions that matter most while pumping. Contact us today to learn how.
