Formation damage Experts

Most hydrocarbon reservoirs have been in a state of relative equilibrium for millions of years. In attempting to release hydrocarbons, well operations disturb the natural balance of ancient hydrocarbon bearing strata causing formation damage or stimulation. Formation Damage can occur during any stage of a well’s lifecycle. Failure to address this can result in missed opportunities, deferred production, lost production or injection. The global cost of Formation Damage is estimated as billions of dollars annually. Remedial operations producing even a 1.5% increase in permeability can unlock millions of dollars.
