Feasibility of Increasing Oil Recovery by CO2 Injection in Syrian Fields (Deir ez -Zour Region)
Abstract
Oil-production from enhanced oil recovery (EOR) project continues to supply an increasing percentage of the world's oil, about 3% of the worldwide production
Now comes from (EOR), and this percentage is increasing with time, because of the conventual’s oil production has continued to full and is not – currently – enough effective, therefore, the importance of choosing the "best" recovery method becomes increasingly important to petroleum engineers.
The objectives of this research: to present technical and economical feasibility for (EOR) by using miscible carbon dioxide (CO2) in Syrian oil fields (Deirez-zour region, essentially Alm field), so that CO2-EOR improvement displaces oil left in place (after primary production and secondary water flooding which has been successfully injected in these fields for many years) via achieving several properties especially:
1) Reduction of oil viscosity,
2) Swelling of oil volume and
3) Acidic effect on rock.
The candidate Alm field in Deirez-zour was studied in order to determine potential (EOR-CO2) by knowing the Alm characteristics (geological and engineering review) that adapted with CO2 condition injection and presenting exhaustive screening, it was recommended that CO2 miscible (water-alternative -gas) or CO2-WAG has accepted as an effective technique for (EOR) with Alm reservoir conditions.
The recovery factor predicted by CO2 in Alm about 12% OOIP (original oil in place), that mean about 32 MMBO (million barrels of oil).
Economical analysis: (capture, compression, transportation and injection costs), capital expenditures (CAPEX), operational expenditures (OPEX) were presented depending on previous and current onshore experience.
