Core Flow Testing


Core Lab’s Core Flow Testing offers a broad range of services related to formation damage, completions and stimulation. Whether it is testing to compare the damage created by different fracturing fluids or effectiveness of different acidizing packages, the core testing group’s goal is to get you more value out of your well service dollar. Unbiased comparisons of different service company products allows the operator to better choose which product is right for his application and to avoid pitfalls that could cost thousands in lost revenue by testing products before field application.


Core Flow Testing

Examples of Core Flow Testing services offered are:

  • Fluid compatibility and critical velocity flood testing
  • Fracturing and gravel packing fluid formation damage testing
  • Mud damage and removal evaluations
  • Matrix acidizing of sandstones and carbonate formations
  • Capability to flow brine, oils and methane gas
  • Capability to evaluate very low permeability down to 1 microdarcy
  • Custom designed equipment and test procedures to meet customer needs

In addition to our major services, the Core Flow Department offers other services such as, capillary suction time tests for fluid compatibility, routine API and dynamic fluid loss studies, water analysis, oil analysis, paraffin and asphaltene content of oils, gel residue, and API proppant and gravel pack sand quality control. Other departments provide support with x-ray diffraction analysis, SEM, fluid rheology, CT scanning, and routine core analysis for air permeability and porosity.

We pride ourself in custom designing tests and equipment to more closely simulate the down-hole application to give more realistic results. To this end a number of pieces of specialized equipment have been build, such as, the dyanmic leakoff core holder pictured that provides full face exposure of the core to simulate formation damage from gel during a fracturing treatment or mud during drilling operations. Other equipment includes a perforation tunnel model, true radial flow cell, and multiple pressure tapped core holders. An on-site machinist allows us to rapidly develop equipment for special testing needs.
