Mitchell Rotary Rig #21 is the newest and most advanced rig in the Illinois Basin. It has depth capabilities of up to 12,500 feet (3.81 km) total vertical depth (TVD) and full horizontal and directional capabilities.

Rig #21 has a 17 foot (5.2 m) Kelly Bushing Height (KB) and is outfitted with an 800 Bbl steel pit system that is equipped with dual shaker technology as well as 1,000 GPM mud cleaning capabilities. This rig can be outfitted with up to two 1,005 hp triplex pumps with 5,000# fluid ends. Rig #21 has handling equipment for slim hole and regular hole drill strings. It is outfitted with a full stack blowout preventer (BOP) and can also utilize a rotating head if requested.

Carbon Capture Sequestration and Enhanced Oil Recovery (CCS-EOR)

In an effort to make oil and gas production (as well as other industries) carbon-negative , the demand for deeper drilling technology is on the rise to pump and store carbon dioxide (CO2) below ground. This technology is called Carbon Capture Sequestration (CCS).

Carbon dioxide gas can also be injected into aging oil fields to boost production - a procedure known as enhanced oil recovery (EOR). Crude absorbs CO2 which makes the oil less viscous helping it to flow more easily. Additionally, approximately 50% of carbon may remain trapped in an oil formation which can provide a storage opportunity to isolate CO2 from coal-fired power plants and other industrial factories.

Mitchell Rotary Rig #21 has the capability to drill the depths required Carbon Capture Sequestration and Enhanced Oil Recovery (CCS-EOR) technologies.
