Enhanced Oil Recovery Studies

Primary and secondary recovery methods typically recover 30 to 40 percent of the oil initially in place. Capillary trapping of oil and limitations of the primary and secondary recovery methods leave behind a substantial volume of oil in the reservoir.  Advanced tertiary recovery methods, such chemical, gas and thermal recovery techniques, can be successfully implemented to enhance oil production from mature reservoirs.

Designing EOR methods requires laboratory tests and numerous simulation studies to select EOR methods, estimate EOR benefits, assess uncertainties, and appropriately forecast performance. D&M has performed feasibility studies, supervised laboratory tests, designed field pilots, and performed field-scale evaluations on numerous fields, examining:

Chemical EOR
Gas EOR
Thermal EOR

Since 2000, D&M has completed multiple detailed studies of miscible gas, miscible water-alternating-gas, and chemical surfactant-polymer injection in several fields in North Africa.  We have also performed a detailed field-pilot study on miscible gas and chemical EOR for a large field in Middle East. More recently, we have completed detailed studies of gas EOR for fields in Alaska.
