Science-Based Forecaster Tool "SBF"
The Physics-Based Approach to Type Well Profiles (TWPs)



Proud Partners With


USI leverages a streamlined and automated workflow driven by full-field CMG simulations to generate physics-based type curves for primary and infill wells in unconventional reservoirs.

Our Science-Based Forecaster (SBF) software uses reservoir, completion, production and pressure data to quickly reveal solutions for widespread industry challenges such as:

  • Infill well underperformance due to well interference, primary depletion, and downspacing

  • Drainage area miscalculations for vertical stacking, lateral spacing, and fracture mitigation

  • Negative impact of total recovery due to shut-ins, crossflow, proppant damage, and flowback strategies

  • Reserves revisions using statistical and analytical methods

  1.  "We can forecast production in resource plays more accurately using simulation than with conventional decline curve analysis or conventional construction of type wells.

  2.  Our methodology makes simulation a practical tool because hundreds of thousands of simulations have been run previously, stored, and accessed for reservoir and completion properties within a certain known range. This process is both rapid and rigorously based on fundamental physical principles, unlike conventional DCA and type well construction.

  3.  Our methodology allows us to model interference between wells, influenced both by well spacing and timing of start of production in primary and infill wells.

  4. We applied our methodology to Contango wells in the Delaware Basin and demonstrated its practical advantages over alternative approaches." Dr. Lee

USI's Mission

USI Technology is at the intersection of leading reservoir simulation technology and the high demand for quality and integrity in SEC Reserves reporting. We help address major engineering challenges for unconventional reservoirs.

USI Customer Testimonials

"Using USI has been insightful experience to get a better understanding of well performance. I appreciate their usage of physics based type curves to honor the fundamentals of reservoir engineering."  Yogashri Pradhan, P.E., SPE Permian Basin Section Chairman 2020-2021, and Sr. Reservoir Engineer at Endeavor Energy Resources.

Wade Wardlow, Sr. Reservoir Engineer at Contango Oil & Gas stated that “USI has taken some of the best modeling tools available, numerical and analytical modeling, and innovated a cutting-edge approach that has provided us with physics-based results.  Their process has given us the ability to evaluate a wide range of development scenarios in short amount of time.  They have provided us with innovative technical solutions that have proven to be very cost effective for our project.  I highly recommend USI and plan to utilize their expertise in upcoming projects.”
