7/13/2018 | For the testing process the flow of our wells is as follows;
From the well, through a sand knockout and into a high pressure, three phase separator that separates out oil, gas and water. Each well produces into its own dedicated high pressure separator.
The gas is initially sent to a single Q-5000 combustor where it is burned. Once the well cleans up it is no longer burned but sent down the well flowline to the production facility so that it can be sold.
The oil is pushed from the high pressure separator into a low pressure separator. The low pressure separator is in place to allow the oil to flash at a lower pressure. That gas is piped from the low pressure separator, through a liquid knock out and into an ECD that burns those vapors. The oil then goes from the low pressure separator to either a sealed tank or down the flowline and into the production facility where it can be sold. The water goes from the high pressure separator into a sealed tank. Both oil and water tanks are sealed forcing any VOC’s through a liquid knock out so they can be burned.
During the testing phase, all tanks are set inside of a 2 ft high containment. For 1 well we will set one High Pressure separator, 1 Low pressure, 2 sealed water tanks and 1 sealed oil tank, 1 Q-5000 (can handle up to 3 wells), 2 smaller Cimarron style burners. |

Test separators, associated flow lines and sand traps shall be installed on-site to accommodate green completions techniques pursuant to COGCC Rules. During flowback, production will be sent through a high pressure separator and into separate sealed oil and water tanks. The tanks will have a dedicated VOC line to capture any vapors. VOC lines are routed a minimum of 75’ away from the tanks to a combustor to burn. Any sales gas from the separator will be routed a minimum of 75’ away to an enclosed combustor to burn. This is only until the well cleans up to the point that it can go down the flowline to the production facility.
The flowback tanks are anticipated to be on location for ~90 days. |
