Fann Instrument Company

What Fann Instrument Company does

Fann Instrument Company, headquartered at 14851 Milner Road in Houston, Texas, designs and manufactures instruments for measuring the physical and chemical properties of fluids — particularly flow, viscosity, filtration, and cement strength. Founded in 1938/1939 and operating continuously for over 85 years, the company is organized as a private corporation and operates as a wholly-owned subsidiary of Halliburton (evidenced by Halliburton-linked corporate governance pages on the Fann website). The product portfolio is the most comprehensive in the oilfield testing instrumentation category, spanning rotational viscometers (Model 35 — described as the industry standard — Model 45 APV, RheoVADR, Model 50SL, iX77), HPHT consistometers (Model 640/640CC, 422, 415C, 415SGS) rated up to 40,000 PSI and 600°F, ultrasonic cement analyzers (Model 304, Twin Cell UCA 420ATC, Model 520 HT UCA, Modular UCA), filter press units (API LPLT and HPHT), permeability plugging apparatus, retort kits, mud balances, roller ovens, and an array of portable mud test kits. Supporting products include chemical reagents, lab equipment and supplies, and a Windows-based Data Manager software used to control and report on Fann instrument testing. Most instruments conform to American Petroleum Institute (API) and American Society for Testing and Materials (ASTM) standards; selected products carry IEC/EN 61010 electrical safety certifications.

Revenue is generated through three streams: (1) one-time hardware sales of instruments, accessories, test kits, portable laboratories, reagents, supplies, and replacement parts; (2) software licenses for Data Manager and related control software (Model 50, UCA, MACS II, Model 290); and (3) technical support and repair services, including a 24/7 Technical Support Hotline and Return Material Authorization (RMA) workflow staffed by qualified field-service technicians. The company serves vertical end markets in oilfield testing — drilling fluids, completion fluids, fracturing fluids, oil well cement, and industrial slurries — with named use cases spanning laboratory research and remote field operations; additional use cases extend into industrial applications such as water drilling, horizontal directional drilling, drilled shaft construction, and mining. Customers include oilfield operators, drilling contractors, and service companies.

Go-to-market combines direct sales for US customers (Customer Service 1-800-347-0450, PO Box 4350, Houston, Texas 77210, with RMA shipping at Gate 5A, Houston) and a global authorized distributor network of 25+ regional partners covering 9+ geographic regions across Africa, Asia, Australia/New Zealand, Canada/Mexico, Europe, Middle East, the United States, CIS, and South America. Marketing channels center on the corporate website, a YouTube channel hosting product introduction videos and a Houston facility tour, technical documentation and data sheets, and distributor-led engagement. Pricing is not publicly disclosed; quotes are obtained via direct contact or distributor inquiry. The company maintains trademarks across its portfolio including Fann, Multi-Mixer, RheoVADR, PORTA LAB, MACS II, and iX77.
