Halliburton Company is a US-based energy services company and one of the world’s largest providers of products and services to the upstream oil and gas industry, with a patent portfolio spanning drilling systems and directional drilling, measurement and logging while drilling, hydraulic fracturing and stimulation, cementing and drilling fluids, well completions and production tools, artificial lift, wireline and perforating, reservoir evaluation and formation testing, coiled tubing and intervention, and digital, automation, and subsurface software. Its filings cover fracturing fluid chemistry and proppant delivery, downhole tool and sensor design, geosteering and closed-loop drilling automation, cementing and zonal isolation, completion and perforating systems, and data and modelling platforms for well construction and production. The company operates through its Completion and Production and Drilling and Evaluation divisions, and the portfolio reflects more than a century of oilfield technology research across multiple decades and jurisdictions.
Halliburton’s patent portfolio comprises 77,336 patents distributed across 19,247 simple families and 18,137 extended families. The portfolio spans 73 jurisdictions and includes patents associated with drilling, hydraulic fracturing, completions, cementing, reservoir evaluation, well intervention, and digital oilfield technologies.

Halliburton’s portfolio consists of 32,974 active assets and 44,301 inactive assets. Active holdings include 21,061 granted patents and 11,913 patent applications. The large inactive base, led by abandoned applications and patents expired due to term and maintenance fees, is characteristic of a research portfolio accumulated over more than a century of oilfield technology development.
Halliburton’s patents span 73 jurisdictions, with the United States accounting for the largest share of filings and grants.
Total Patents: 77,336
The portfolio is distributed across North America, Latin America, Europe, and Asia-Pacific. The strong presence in Canada, Australia, Norway, the United Kingdom, Brazil, Mexico, and Argentina is distinctive and reflects the geography of major conventional, offshore, and unconventional basins, including the North Sea, Canadian heavy oil, Brazilian pre-salt, and the Vaca Muerta shale in Argentina, where Halliburton’s drilling, fracturing, and completion technologies are deployed.
Halliburton’s patent portfolio is led by the industrial domain covering drilling equipment, fracturing systems, and completion tools, followed by a substantial consumer goods share reflecting equipment and materials classifications. Notably, software accounts for roughly 19% of the portfolio and computer systems a further 13%, together reflecting Halliburton’s significant investment in drilling automation, geosteering, and subsurface software platforms such as LOGIX and its digital and data management offerings.
The citation network is dominated by the small group of firms that lead oilfield services technology. Beyond Halliburton’s own filings, the largest citation volumes involve direct competitors SLB (formerly Schlumberger), Baker Hughes, Weatherford, and NOV, alongside major operators ExxonMobil, Shell, Chevron, and ConocoPhillips and national programmes in Saudi Arabia and China. The dense mutual citation among Halliburton, SLB, and Baker Hughes underlines the intensely competitive and heavily cross-cited nature of the sector.
Halliburton’s litigation dataset includes 107 patents that have been involved in litigation matters, 64 petitions, 30 reexaminations, and 55 Chinese Patent Reexamination Board proceedings. The dataset also includes 3 active cases, 76 inactive cases, 18 appeals, and 135 related parties, reflecting the competitive and heavily cross-licensed nature of the oilfield services sector and the frequent patent disputes among its leading firms.
Halliburton’s patent portfolio consists of 75,094 originally assigned patents and 2,242 acquired patents, meaning approximately 97% of the portfolio was developed internally. Acquired patents originate largely from operating companies, reflecting Halliburton’s history of targeted technology acquisitions to complement its extensive in-house research base.
2025 / 2026 – Technology-focused acquisitions (Sekal and InformatiQ)
Halliburton has recently pursued targeted software and automation acquisitions to strengthen its digital drilling portfolio. It acquired Sekal, a Norway-based drilling automation specialist, integrating its technology into the LOGIX automation platform to deliver closed-loop drilling that produced back-to-back record wells for Aker BP in Norway. In 2026 Halliburton announced the acquisition of InformatiQ AS, another Norway-based software company, converting a long-standing collaboration into full ownership to strengthen its agile asset management offerings.
2016 – Terminated Baker Hughes merger
Halliburton’s proposed acquisition of rival Baker Hughes, announced in 2014 at a value of approximately US$28 billion, was abandoned in 2016 after failing to obtain antitrust clearance from US and European regulators. Halliburton paid Baker Hughes a US$3.5 billion break-up fee, one of the largest in corporate history, and the two remain direct competitors, a dynamic reflected in their dense mutual patent citation.
Halliburton’s scale reflects a long history of oilfield acquisitions, most notably the 1998 merger with Dresser Industries, which brought Baroid, Sperry-Sun, and other drilling and fluids businesses into the company, along with numerous subsequent technology and services acquisitions across drilling, completions, and production.
Halliburton Company is a publicly traded energy services company listed on the New York Stock Exchange (HAL) and a component of the S&P 500. It operates through two divisions, Completion and Production and Drilling and Evaluation, and is the world’s second-largest oilfield services company and the largest provider of hydraulic fracturing services, with headquarters in both Houston, Texas and Dubai.
