 Stim-Lab has designed and built specialized testing equipment that bridges the gap
between laboratory size and field size equipment. Field size mixing equipment and
a stainless steel heat exchanger unit are used to match a desired shear history
prior to measuring rheology and proppant transport. Measurement options include
pipe rheology through 4 sizes of pipe, slot rheology at simulated reservoir temperatures
up to 300 degrees F, and dynamic and static proppant settling in a high pressure,
high temperature slot. Fluid may also be loaded dynamically into a Fann 50 viscometer
or Stim-Lab Low Shear Rheometer to obtain rheology data.
Research is carried out by the Stim-Lab consortium for "The Investigation of the
Rheology and Proppant Transport of Common Fracturing Fluids". This group studies
various topics including theoretical models for proppant rheology and the transport
of foams and high temperature fluids. Membership in the consortium is available
on a yearly basis.
Research is also carried out by the Stim-Lab Screen Cleanup Consortium. Testing
evaluates various cleanup methods for plugged screens in horizontal wells as well
as screen performance under open-hole conditions and in the presence of a gravel
pack.
Stim-Lab has made a major equipment commitment in order to get the closest possible
simulation and prediction through Large Scale Testing. |
