| Title: |
Connect Casing to VRU. |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Connect Casing to VRU. Crude-oil wells produced with downhole pumps accumulate gas in the casing that may be vented directly to the atmosphere to prevent vapor lock of the pump. Connecting the casinghead vent directly to an existing VRU can reduce methane emissions. Operating requirements may include a pressure regulator if low-pressure casinghead gas is combined with higher-pressure sources at the suction of a VRU. Only small-diameter piping is required to join a casinghead vent to the VRU." [see Table 2 and 3 in source document for cost, benefits and production characteristics] |

| Cost-Benefit Analysis: |
Cost & Benefits:
Equipment Cost=
$1,000;
O&M Cost=
$3,400;
Saleable Gas Saving (Mcf/d)=
27.0;
Expected Payback=
Less than one year, around one month
with price assumption $5/Mcf;
Operating Requirement=
Pressure regulators may be required;
Basis for cost saving=
Connecting one casing to an existing
stock tank with VRU, O&M cost is incremental
electricity;
Other Benefits=
Reduce VOC and HAP emissions. |
