EN-FAB

What EN-FAB does

EN-FAB, Inc. is a Houston, Texas-based engineering, fabrication, and packaging company founded in 1980 by Daniel Industries Inc., specializing in custom surface equipment for the upstream and midstream oil and gas industry. The company designs, fabricates, and commissions skidded and modular equipment across four primary product lines: Enhanced Oil Recovery (EOR) systems including once-through steam generators, feed water treatment, multi-media filters, waterflood packages, and chemical injection; gas gathering and oil production equipment such as early production facilities, separators, heater treaters, desalters, and produced water packages; oil and gas pipeline infrastructure including slug catchers, surge control, pipeline launchers/receivers, and gas conditioning; and fiscal metering and measurement stations for custody transfer, including LACT units, city gate stations, meter provers, leak detection, and quality analyzers. EN-FAB holds the exclusive worldwide license from Shell Oil Company to manufacture, market, and service the DAN-SQUID Two-Phase Steam Distribution System and the associated DAN-STM portable steam quality measurement system, both of which address a key technical challenge in thermal EOR (maintaining vapor-liquid ratio across branched steam injection wells). The company has 69 employees and operates from headquarters in Houston with regional offices in Bakersfield, California (USA West Coast), Mexico City, and Muscat, Oman, the latter established through the 2018 acquisition of Oman Metal Industries and Contracting LLC (OMI).

EN-FAB generates revenue primarily through project-based custom equipment sales to enterprise customers in the oil and gas industry, complemented by a Design, Build, Own, Operate, Maintain (DBOOM) service offering for EOR and cyclic steam injection projects. Equipment pricing is quote-based with no published rate cards, and sales cycles are long-term enterprise engagements requiring technical specifications, engineering design, and fabrication. The customer base consists of national oil companies (PDO, KOC, Pemex), pipeline operators (Caspian Pipeline Consortium, Energía Mayakan), and EPC contractors (WorleyParsons, Fluor Daniel Williams Brothers, SICIM), with project scopes ranging from single steam generator units to 108-skid pipeline packages and 11-station crude oil metering systems. The company is ISO 9001, ISO 14001, and OHSAS 18001 certified, holds ASME U/U2/S/PP stamp accreditation and National Board of Boilers & Pressure Vessels Inspectors (NB & R) registration, and received the U.S. President's 'E' Award for Exports in 2016 in recognition of export sales growth from 40% of total revenue in 1995 to nearly 90% by 2016. Over its 35+ year operating history, EN-FAB has delivered 2,141 projects, created 3,918 engineering drawings, and supplied 236 steam generators across 11+ countries. Go-to-market is direct enterprise field sales through the four regional offices, supported by a corporate website with Request a Quote functionality, trade show presence, and a 24/7 DBOOM operations capability that includes asset lifecycle management and on-site training.
