The development of the Fluid Rock Interaction Laboratory (FRIL) was motivated by operators wanting to couple the geomechanical response of a core sample to fluid contact. For example, under a specific stress state, an acid may be injected into a sandstone to remove near wellbore damage and may weaken the rock. Being able to evaluate structural changes as well as injection/production behaviour of the core, simultaneously, is the key driver behind this.
FracTech now has the capability to run core flood tests on samples under a wide range of conditions. Example studies include:
Equipment
Three core flood test rigs to 5000psi, 150C
Hastelloy components for acid handling (including HF)
Real time bulk compressibility measurements to assess porosity changes (soft chalks for example)
Fann 35 for YP, PV
HPHT filter press
Grace rheometers
High shear mud mixing equipment with hot oven rolling
Low shear solids addition safe mixing
