Laboratory Services

NSI Laboratories offers a broad range of testing services to meet the petroleum industry's needs in drilling, completion, and well stimulation. Through our relationship with the University of Oklahoma we now offer a complete line of petrophysical services as well.

The laboratory's mission is to collect and measure data that improves understanding of the fracturing process in a given reservoir, thus simplifying an otherwise complex process and improving the likelihood of success on any fracturing program.

Rock Mechanics Lab

Fracturing Software

At the heart of our services is the rock mechanics laboratory that consists of a triaxial load cell on which stress-strain measurements can be made to determine:

  • Young's Modulus
  • Poisson's Ratio
  • Ultimate rock strength
  • Pore volume compressibility
  • Effects of Stress Cycling
  • Failure envelope

Additionally, a "Built for Purpose" fines migration and embedment testing service is available for determination of the optimum completion technique for wells producing from unconsolidated reservoirs and to establish gravel size criteria. Other laboratory capabilities include proppant quality control testing, particle size distribution, and proppant stress cycling affects on fracture conductivity.
