Salt Water Disposal Facility Design

Confidential Client, Mountrail County, North Dakota

Salt Water Disposal Facility DesignEngineering Analytics staff prepared plans and specifications for a new salt water disposal facility in Mountrail County, North Dakota. The commercial facility is designed to take produced water and frac flowback and process the fluids prior to injecting down a deep disposal well permitted for 5,000 bbl/day. Fluids are received by tanker truck, filtered to remove solids, and sent to a tank battery for further settling and processing. Oil separation is enhanced by a gunbarrel separator prior to fluids entering injection feed tanks. EA provided project management, coordinated site surveying and geotechnical investigation, was the Engineer of Record for design, and facilitated procurement of major equipment, piping materials, and construction contractors. Mechanical equipment, including the injection pump, transfer pumps, and filtration, is housed in a custom designed pump house with a separate electrical control and equipment room.

Produced Water Treatment & Surface Discharge Support

Energy Corporation of America, Carbon County, Montana

Produced Water Treatment & Surface Discharge SupportEngineering Analytics staff provided technical support for a conventional oil and gas production facility through the characterization of a 3,000 bbl/day produced water stream. EA analyzed water constituents, and evaluated viable water management options such as underground injection, on-site evaporation, treatment, and surface discharge. On-site treatment by reverse osmosis (RO) to reduce the total dissolved solids (TDS) with a final chemical addition reduce the pH and sodium adsorption ratio (SAR) was recommended.

Salt Water Disposal Facility Design & Soil Remediation

Confidential Client, Burke County, North Dakota

Salt Water Disposal Facility Design & Soil RemediationEngineering Analytics staff prepared engineering plans and specifications to construct surface facilities at a remediated salt water injection site. The facility is designed to take produced water and inject it into a deep disposal well. Oil separation is enhanced by a gunbarrel separator prior to fluids entering injection feed tanks. The civil design plans corrected site drainage, addressed protection of a nearby wetland lake, and improved delivery truck access and safety for unloading. The site and facility drawings included a grading plan, civil site layout, piping and instrumentation diagrams, piping layouts with a bill of materials, electrical area classification plans, electrical site layout, a power distribution one-line diagram, panel schedules, and control system architecture drawings.

Produced Water Treatment & Surface Discharge Support

Baldwin Lynch Energy Corporation, Carbon County, Montana

Produced Water Treatment & Surface Discharge SupportEA staff characterized a 1,500 bbl/day produced water stream and evaluated management options. The owner/operator selected on-site treatment by reverse osmosis (RO) followed by surface discharge under a Montana Pollutant Discharge and Elimination System (MPDES) permit. EA staff provided technical support in design of the treatment process which included final chemical conditioning for pH and SAR. The treated water stream is surface discharged to an ephemeral drainage which intersects the Clarks Fork of the Yellowstone River one mile downstream. EA staff prepared and negotiated the MPDES application for an Individual Permit. EA also designed a lined surface impoundment/pit for on-site management of concentrated brine solution and prepared the pit permit application for Montana Board of Oil and Gas Conservation.
