The New Frontier in Reserves Estimation 


Proud Partners With

USI leverages a streamlined and automated workflow driven by full-field CMG simulation to generate physics-based type curves for unconventional reservoirs.

Our Science-Based Forecaster (SBF) software utilizes engineering data to quickly reveal solutions for widespread industry challenges such as:

  • Drainage area definition for vertical stacking and lateral spacing

  • EUR changes from Fracture Driven Interaction, downspacing and offset well timing

  • Total Recovery effect from bottom-hole pressure drawdown

  • Reserves revision using statistical and analytical methods

December 2019 - USI welcomes Dr. John Lee to the Board

“Some publications have documented conditions under which reservoir simulation has been found to be a reliable technology. When these conditions are satisfied, we can be confident that we can use simulation to establish EUR in a reservoir. We can use simulation to establish with confidence the characteristics of our static reservoir model, particularly original oil in place (OOIP) in the reservoir. ” -Dr. Lee

Unconventional Subsurface Integration LLC is at the intersection between leading reservoir simulation technology and the high demand for quality and integrity in SEC reserves reporting along with addressing major engineering challenges for unconventional reservoirs. Our clients include PE backed, large privately owned and independent operators.  

A few of the companies familiar with our work are shown below.
