Keystone Engineering is a leader in many fields of engineering, and our Mechanical Engineering service provides a great example. Our comprehensive approach to projects means that you can expect high quality deliverables without affecting your project schedules.
Keystone provided front end engineering design (FEED) and detailed engineering design for a 30 MMSCFD Enhanced Oil Recovery Pilot in the Eagle Ford black oil area. The pilot area consists of two adjacent pads, with 21 injection wells separated by six buffer wells to monitor pressure and communication. The project scope included extending the well pad to accommodate gas injection and processing trains. The new processing train compresses, sweetens, and dehydrates gas utilized for fuel gas and flare purge with the remaining volume entering a header common with the injection compressor suction and gas lift pipeline.
Keystone provided project management, engineering, and design services for the West Karnes Gas Expansion Project. West Karnes Central Facility’s original processing capacity was 20 MBOPD liquid and 60 MMSCFD Gas. The production forecast for West Karnes indicated that liquid processing capacity was not a concern at the time. However, future compression requirements and the forecast gas throughput exceeded the original capacity of the gas train. The expansion increased the gas train capacity to 100 MMSCFD. The project elements included new gas cooler, two filter coalescers, dehydration system, fuel gas scrubber, and an amine plant.
Keystone’s scope included engineering and design services for the installation of new and relocation of existing equipment, demolition/abandonment, piping, civil/structural, and instrumentation and electrical design.
To support facilities associated with the Centralized Storage, Keystone provided project management, engineering, and design FEED services. The scope included the installation of temporary storage and stabilization capabilities for the Eagle Ford Region to act as a surge for the Condensate Trunkline. Additionally, the project involved future expansion capabilities for an additional storage tank and vapor recovery to gather the flash gas. The stabilization capabilities were necessary to get RVP to an acceptable level for sales contract. The design criteria associated with the scope included a design storage capacity of 30,000 BBL and a design facility average flowrate of 120,000 BOPD.
To support an increase in the water gathering infrastructure, Keystone provided the engineering, design, and analysis necessary to increase the throughput and capacity as well as mitigate corrosion and improve control. The scope of work included the redesign the pump suction headers to accommodate 75,000 BPD of throughput, the addition of a third water transfer pump with recommendations to increase the current capacity another 50%, replacement of process header piping with internally plastic coated piping to mitigate corrosion, and the addition of two connections to the discharge pump header.
Additionally, the scope included modifying the inlet headers from two separate pipelines with automated control valves and individual flow meters to allow for flow control into the facility as well as the modification of the existing control systems architecture to accommodate the additional valves and instrumentation.
Keystone provided project management, engineering, and design services for the Lake Boeuf Grand Coteau Facility design to support the addition of two new wells and working over the existing Well #1. The new wells required a full facility to produce, separate, store, and sell the oil and gas production.
The scope of work for the new facility design included well flowline rated for SITP of the well (<10,000 psig) for Well #1, well flowline rated for SITP of the well (<15,000 psig) for Well #2 and #3, line heater with line heater fuel gas scrubber, slug catcher, HP and LP separator, fuel gas/instrument gas scrubber, oil heater treater, glycol dehydration package, amine unit for CO2 removal, dewpoint control unit, oil storage tanks, three 500 BBL water storage tanks, one spare storage (slop) tank, tank recirculation/offloading pump skid, HP flare scrubber and pump, LP and HP flare, and LP flare liquid blowcase.
Keystone provided project management, engineering, and design services to add a new offtake/delivery point at the existing Dewitt Central Facility. The project design of the new offtake/delivery point at the current facility pad involved 40Mbpd of unstabilized oil from the Eagle Ford asset. The design also provided constant flow with the existing stabilizer and utilized the existing Eagle Ford Pipeline pressure to provide the motive force.
The scope of the work associated with the new delivery point included a new incoming 12” lateral, 12” pig receiver, provisions for future booster pumps (preliminary sizing, space/footprint requirements, flanged tie-points, and I&E spares), dual/redundant free Water Knock Out packaged skids, interconnecting piping to available tie-points, interconnecting I&E back to the existing facility control system, sleeper/rack supports, and 480VAC power supply to switchrack.
