What Citadel Drilling does

Citadel Drilling Inc. is a privately held Canadian oilfield services company headquartered in Calgary, Alberta that designs, owns, and operates a fleet of six technologically advanced AC triple drilling rigs — the proprietary TA²CT Series 1 and Series 2 — capable of drilling 15,000–25,000 foot vertical and horizontal wells. Its rigs feature an integrated walking system with the lowest compaction rate in the market, 2450hp Quatro pumps with a 7500psi API-certified circulating system, a first-of-its-kind catwalk design for tubular and top-drive handling in North America, dual-fuel capability (up to a 70/30 blend of natural gas and diesel), and programmable anti-collision drilling features. Citadel complements its rig fleet with wholly-owned subsidiary Opla Energy Ltd., which provides managed pressure drilling (MPD) hardware (PMD, MPDSmart manifolds, 3K eRCD) and software platforms (OplaSim simulation, OplaSmart cloud platform with digital twin and machine learning) that integrate into the rig operations.

The company serves oil and gas producers in Western Canada and the United States (primarily west Texas, with operations also referenced in New Mexico) through a B2B direct enterprise sales model, with a VP of Business Development leading client engagement. Citadel generates revenue primarily from drilling rig services billed on a quote-based, contract basis to enterprise E&P clients; pricing is not publicly disclosed. It operates from corporate headquarters in Calgary and operations centers in Odessa, Texas and Leduc/Nisku, Alberta. The company is backed by ARC Financial Corp., which holds board representation, and is led by founder-CEO Dan Hoffarth, COO Dave Hoffman, and CFO Doug Robinson (named CFO in November 2024). Citadel also maintains a ZERO² goal of zero workplace injuries and zero environmental incidents, supported by an externally audited QHSE management system.

Citadel was established in 2014 as part of the "modern energy wave" by experienced drilling professionals — many recruited from Nabors Drilling — who designed the TA²CT rig platform from the ground up incorporating feedback from potential clients. The company incorporated Opla Energy as an in-house MPD engineering arm, creating a vertically integrated rig-plus-MPD offering that distinguishes it from peers who must purchase MPD capabilities from third parties. Citadel remains private, with no public ticker, no disclosed funding rounds, and no publicly available revenue figures.
