Conventional
Heavy Oil

As part of a long-term partnership with this client, Vista completed the detailed engineering design and procurement of a $3.5 million grassroots heavy oil treating battery processing 2,700-4,000 barrels of oil per day (BPD) or 430 – 635 m3/day of 15 API oil, featuring:

• Production manifold and test treated
• Direct fired treater with desand system
• Inlet emulsion/sales oil exchanger and sales oil tankage with pipeline tie-in
• Produced water skimming, filtration and water reinjection pumping facilities
• Desand and recycle tankage and associated pumps
• Utility systems: glycol heating system serving both process and utility requirements, instrument air, fuel gas and flare

Vista also completed the detailed engineering design and procurement for the battery’s free-water knock-out (FWKO), test treater, and production satellite.  The project was needed for this heavy oil battery expansion to handle 5,000 BPD or 800 m3/d of oil and 20,000 BPD or 3,200 m3/day of water, featuring:

• Direct fired FWKO vessel with desand system
• Direct fired test treater sized for 60 m3/d oil and 150 m3/d water
• Produced gas cooler
• Inlet manifold extension
• Remote satellite manifold

As part of a long-term partnership with this client, Vista completed the detailed engineering design of a grassroots heavy oil treating battery processing 4,000 barrels of oil per day (BPD) or 635 m3/day of 15 API oil, featuring:

• Production manifold
• Two test treaters
• Direct fired treater with desand system
• Inlet emulsion/sales oil exchanger and sales oil tankage with truck loading
• Produced water cooling, skimming, filtration, and water reinjection pumping
• Desand and recycle tankage and associated pumps
• Glycol heating system serving both process and utility requirements
• Onsite generation of electrical power (480v, 3ph, 60hz)
• Fuel and flare utility systems

Vista was also engaged to complete detailed engineering design and procurement of multiple battery expansions to this facility including the addition of:

• a pressurized FWKO to increase water handling capacity to 10,000 BPD or 1,590 m3/day, as well as a produced gas dehydration system and an instrument air package;
• a second 6,000 BPD or 950 m3/day water disposal pump with filter and booster pump, as well as a second oil emulsion inlet manifold

Vista completed the detailed engineering design for a grassroots heavy oil treating battery processing up to 1,900 BPD (300 m3/day) of 18 API oil, featuring:

• Production manifold with pig receiver
• Indirect fired test heater and test separator
• Direct fired treater with chemical injection
• Sales oil storage tankage with pipeline tie-in
• Produced water skimming, filtration, and water injection pumping facilities handling 600 m3/day
• Recycle tankage and pumps
• Sour produced gas compression (40 103 m3/day)
• Utility systems: glycol heating system, instrument air, fuel gas and flare

In order to optimize the steam generation and fuel and power usage at a client’s in-situ toe-to-heel air injection (THAI) project, Vista undertook a study to evaluate the potential for combustion of low-BTU gas in the project’s on-site turbine.

The project was completed on time and on budget between February and July 2009.

Vista performed the detailed engineering design for a client planning to drill additional production wells at an existing conventional oil battery. Vista was contracted to design the emulsion tanks and related gas and fluid treatment and handling processes, as well as the piping from the production wellhead to the on-site tank farm.

The project was designed to meet the client capacity specifications of 300 m3/day of sour oil production as well as produced gas. The test and production tanks required 4-day production storage capacity.

As part of a long-term relationship with this client, Vista completed engineering studies, pre-FEED, FEED and detailed engineering design for a grassroots oil treating battery initially processing 3,000 barrels of oil per day (BPD) or 412 m3/day.

Vista was also engaged to perform subsequent expansion work to increase the production rate to 15,000 BDP or 2,060 m3/day. Features included:

• Production manifold and test tank
• FWKO and direct fired treaters with desand systems
• Inlet emulsion/sales oil exchanger, sales oil cooler, produced water cooler
• Coalescing tank and sales oil storage tanks with future pipeline tie-in
• Produced water skimming, filtration and water reinjection pumping facilities
• Desand and recycle tankage and associated pumps
• Utility systems: glycol heating system (process & utility) glycol cooling system for produced gas cooling, instrument air, fuel gas, and flare
• Steam expansion – grassroots thermal steam generation facility with water treatment system, three 50 MM BTU/hr steamers, steam distribution system to 15 wells, and thermal production gathering system complete with manifold and test separator
