Abstract: According to the
low-cost development strategy of Dongsheng Gas Field, the potential of vented
gas of pilot production wells shall be tapped. Based on recovering processes
comparison and vented gas emission characteristics, a low-cost recovering
process suitable for Dongsheng Gas Field was proposed. Moreover, economic
evaluation was performed on the process, the conclusion is that vented gas
recovery by means of CNG is practicable, the recovering project of vented gas
is short in payback period, high in IRR, and low in investment risk.
Keywords: Dongsheng gas field;
vented natural gas; recovery; process; economic evaluation
