Oil & Gas / Midstream

ETA team members have performed independent engineering project feasibility analysis, and owners engineer project planning and execution to the oil & gas / midstream industry sectors.  We can streamline developer decision making, project planning, ensure successful project execution, and ultimately successful project finance. Our team can develop project conceptual designs, lead optimal commercial technology selection, and ensure project regulatory and financial viability. ETA has the expertise to validate preliminary designs to successfully acquire entitlements for construction and operation, then evaluate bid packages to select optimal EPC designated technologies, schedule, budget, terms, and conditions.

ETA can identify and mitigate potential project technical and business risks and help negotiate appropriate risk allocation among transaction, development, or project finance parties.  Once the project is approved, ETA can perform construction monitoring and EPC contract management support. ETA can also leverage its working relationships with industry recognized technical specialists to perform additional required detailed analysis, evaluation, and detailed design.

Notable Projects

• Confidential Oil & Gas Project, USA – An ETA member managed a feasibility study that led to the engineering and procurement of an oil/water/gas gathering system and central processing facility for a 700+ well horizontal drilling program. The facility incorporated the economic and environmental mitigation recommendations of the study in a design that allows for future expansion. Having this efficient infrastructure in place has allowed the owner to remain one of the lowest cost producers in the region.
• PHMSA UGS Subject Matter Expert – ETA provides support to the DOE Pipeline and Hazardous Material Safety Administration. (PHMSA), as a subject matter expert in underground natural gas storage. ETA worked with PHMSA auditors to provide technical expertise on multiple facilities, including cavern storage, reservoir storage and aquifer storage. ETA continues to assist PHMSA in performing site inspections, records reviews, and interviews of site personnel. Deliverables include facility specific exit interviews and “90-day” reports.
• NGL Storage Development – An ETA member provided project owner’s engineer role technical review of development plans to construct multiple bedded salt caverns for NGL storage to serve natural gas liquids (NGL) markets in Appalachia, the Mid-Atlantic and the Northeast. The reviews examined the geology of cavern intervals, including integrity of top sealing formations, cavern drilling and completion plans, related proposed cavern design, cavern mining plans, and the effect of NGL operations on cavern integrity and potential subsidence.
• Bitumen Pipeline Acquisition – An ETA member provided a technical review supporting the financing and acquisition of dual pipeline assets, including pumping, storage, blending, and measurement facilities for the transportation of bitumen blend and diluent between heavy oil extraction facilities and refining terminals.
• Wolf Infrastructure ACTL CO2 EOR and Sequestration​ – An ETA member provided technical due diligence to an institutional investor for the acquisition and construction of the Alberta Carbon Trunk Line (ACTL), a 149-mile CO​2​ pipeline including collection and compression of anthropogenic CO​2​ from multiple industrial sources in northern Alberta for utilization in enhanced oil recovery (EOR). The ETA member also performed a comprehensive technical review of the CO​2​ EOR project’s design and expected performance for two mature Alberta oil fields owned by a consortium partner.
• Petra Nova West-Ranch Field CO2 EOR and Sequestration​ – An ETA member provided an international debt consortium with a technical due diligence review of a coal powered generation carbon capture CO​2​ EOR project, including CO​2​ compression, design, and construction of an 80-mile CO​2​ pipeline, and detailed design for complete redevelopment of the multiple reservoir CO​2​ EOR field. The technical review included review of the field geology, EOR simulation results, production surface facilities, recycled CO2 capture/treatment/recompression facilities, and financial model inputs.
• Magnum Development – ETA members aided in the development of a 13 Bcf cavern storage project in central Utah, assisting with pre-engineering design and cavern optimization studies. These studies included an evaluation of various combinations of seasonal versus high frequency storage cycle operations, with simulations including optimal gas compression sizing for compensated brine versus natural gas pad designs. Investigations were also undertaken on the performance of an integrated 60-mile bidirectional natural gas pipeline header. The facility is currently storing light hydrocarbons underground, and is part of the Magnum Western Energy Hub, that is soon to become part of the world’s largest green hydrogen production and storage project.
