Bring wellsite portable equipment that cleans up most of initial produced gas to pipeline sales standards. |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Green Completions: The common practice in completing a gas well following drilling or workover is to flare or vent initial produced gas to scour the producing zone of drilling fluids, sand, and water. An alternative is to bring to the wellsite portable equipment that cleans up most of the initial produced gas to pipeline sales standards. Equipment includes portable sand traps, separators, and a dehydrator if the permanent installation is not completed or is out of service for maintenance. For low-pressure wells, it may be necessary to include a portable compressor that can take suction off the sales line to inject gas into the well to initiate flow and then boost the gas to the sales line until liquids and solids are unloaded. This practice is called "green completions' by some Gas STAR partners." [see Table 2 and 3 in the source document for cost, benefits and production characteristics] |
