WRI - Model AquaTex™ COG - Wastewater Treatment Solutions for the Upstream Oil & Gas Industry
From Industrial Product
We offer AquaTex COG for deployment to oil and gas fields to reclaim, pretreat, and recycle well wastewaters (i.e. drilling fluids, frac flowback, and produced water). It can be deployed as a rugged mobile pretreatment plant, installed as a central pretreatment plant, or integrated as a pretreatment device on the front end of our advanced wastewater treatment plant. Our robust pretreatment train removes suspended solids (TSS) from well and mine wastewaters. Prior to recycling treated wastewater, AquaTex COG's proprietary flocculation/separation/clarification process removes unwanted TSS in a single enclosed ISO-rated tank. It pretreats all wastewaters prior to additional frac stages to significantly reduce water management costs or prior deep well injection to extend the life of the injection well. As a versatile, scalable pretreatment train, it also pretreats acid mine drainage and other mining wastewaters.
AquaTex COG Advanced
AquaTex COG Advanced integrates advanced treatment technology with our pretreatment train to remove both TSS and TDS (total dissolved solids) from well and mine wastewaters. It reclaims, treats, and recycles wastewater or distributes treated wastewater for beneficial uses. Our advanced product line is deployable to oil and gas fields or remote mining operations as mobile or as central treatment plants. Its unique pretreatment process removes TSS and its multi-stage filtration process removes TDS to regulatory standards or producer specifications. Treated wastewater may be recycled onsite, deep well injected, surface discharged or reused beneficial purposes.
Automation Features - Every automated wastewater treatment plant engineered for the upstream and mining industries comes equipped with a state-of-the-art computerized control panel with the latest Siemens PLC technologies, a user-friendly color touch screen for onsite system monitoring and management, and Internet connectivity with full reach-back capabilities to the corporate office for remote system monitoring and management.
Water Treatment Costs - Direct management costs, those related to water acquisition, transport, treatment, and disposal, can range from $3.00 to $10.00/bbl. Water consumption at each new horizontal gas well averages 4 million gallons or 95,000 barrels. If direct management costs average $8.00/bbl to frac a gas well, total water management costs are $750,000 or more. When the average cost to drill a horizontal well is $4 million, the total water management costs can exceed 19% of drilling and completion costs.
Deploying AquaTex COG and COG Advanced can reduce total water management costs by 40% or more over the lifecycle of a gas field or copper mine. If 100 new wells are being drilled in a new natural gas field, treating and recycling well wastewaters could save a producer millions of dollars compared to the traditional offsite hauling/disposal model. The real water management costs begin when wastewaters leave the field.
Variables impacting cost reductions include:
- wastewater quality and volume
- treatment specifications
- freshwater acquisition costs
- water and wastewater hauling costs and
- waste disposal costs.
