A Simulation Study of Simultaneous Acid Gas EOR and CO2 Storage at Apaches Zama F Pool
The Plains CO2 Reduction (PCOR) Partnership is working with Apache Canada Ltd. (Apache) to validate the stored amount of CO2 during ongoingenhanced oil recovery (EOR) operation at the F pool of the Zama oil field situated in northwestern Alberta, Canada. Apache is capturing CO2 and H2S from a nearby gas-processing plant and injecting this stream into the F pool for simultaneous EOR and CO2 storage. Acid gas injection was initiated in December 2006 and is continuing to date. The present compositional flow simulation study aims to evaluate ways for maximizing incremental oil recovery and CO2 storage capacity in this depleted and closed pinnacle reef structure. Two different versions (Version 1 and Version 2) of a constructed static geologic model were used for performing dynamic simulations. In the first simulation scenario that used, the Version 1 static model, additional storage capacity gain by pressure management through water extraction (no oil production) from the water zone below the oilwater contact (OWC) was investigated. The results clearly indicate the viability of formation waterextraction for increasing storage capacity in a closed geologic structure. The second iteration of the constructed static geologic model (Version 2) was chosen for simulating cases of continuing the current EOR scheme with and without a bottom water extractView/Download Document
