JV TASK 7-FIELD APPLICATION OF THE FREEZE-THAW/EVAPORATION (FTE) PROCESS FOR THE TREATMENT OF NATURAL GAS PRODUCED WATER IN WYOMING

摘要: The freeze-thaw/evaporation (FTE{reg_sign}) process treats oil and gas produced water so that the can be beneficially used. FTE{reg_sign} is coupling of evaporation freeze-crystallization, in climates where subfreezing temperatures seasonally occur, this improves economics compared to alone. An added benefit a quality suited for variety beneficial uses produced. evolution, from concept successful commercial deployment, treatment natural has now been completed. In document, histories two individual deployments are discussed. Wyoming, as many other states, permitting regulation disposal and/or facilities depend upon legal relationship between owners facility wells which ''owner-operated'' regulated by Wyoming Oil Gas Conservation Commission (WOGCC) defined an entity only processes comes fields they have equity interest. However, if themore » no interest, considered ''commercial'' permitted Department Environmental Quality. For reason, discussed one related facility, relates facility. Case 1 summarizes permitting, design, construction, operation, performance at located Jonah Field southwestern Wyoming. This was originally owned McMurry Company later purchased Alberta Energy (now EnCana). 2 Great Divide Basin south central Permits required construction operation each described detail. respective qualities feed water, treated concentrate stream presented along with relative yields Treated owner-operated used drilling dust abatement, land application. requirements evaluation use results research confirm economic commercial-scale Further, suitable such irrigation, mix, wildlife or livestock watering, abatement on local roads.« less
