Abstract: The disclosure provides a system to capture greenhouse gas, such as carbon dioxide, from exhausts of greenhouse gas emission sources on industrial sites, such as industrial grade power generators, and liquefy it for temporary onsite storage for collection and transportation to specifics sites for permanent carbon dioxide sequestration or utilization. The system can integrate the greenhouse gas emission source, with exhaust gas collection equipment, greenhouse gas capture equipment, greenhouse gas liquification equipment, and greenhouse gas fluid storage equipment for the onsite collection of the captured greenhouse gas from the greenhouse gas emission sources.

Abstract: The disclosure provides a system to capture on-site greenhouse gas, such as carbon dioxide, from exhausts of greenhouse gas emission sources. The carbon dioxide is mixed with water to form a carbonated fracking fluid portion to combine with a proppant fracking fluid to form the fracking fluid for injection into a subsurface. The carbon dioxide in the carbonated fracking fluid portion is then sequestered into the formation through chemical attraction. The system can be an in-situ closed loop system in that the capture of the wellsite’s carbon dioxide emissions and injection into the formation occur at the same wellsite or nearby wellsites in the same field to avoid long-term surface storage and transportations. The system can be modular, scalable, and transportable. The system can be installed as decentralized individual units coupled with each greenhouse gas generating equipment at the wellsite..

Abstract: The disclosure provides a modular, scalable, and transportable system for capture and sequestration of wellsite greenhouse gas emissions, such as carbon dioxide, by integrating exhaust gas collection equipment, greenhouse gas capture equipment, greenhouse gas compression equipment, and a method enabling sequestration of the gas into well construction equipment and processes. The captured gas can be compressed or otherwise formed into a denser gas fluid, and injected into a geological formation, such as a shale formation. Enhancements to fracking processes can be provided by intercalating or otherwise mixing the gas fluid with fracking fluid. The gas fluid can be geologically sequestered by its interaction with and adsorption into the formation. The sequestered gas fluid can enhance hydrocarbon recovery by reduction of oil interfacial tension in the formation and desorption of methane from the formation. The gas fluid can also be absorbed into the formation or sequestered in other wells or storage facilities.

Abstract: A transportable unit has a skid with a pivot connector to pivotally attach to a first mast leg of a drill rig mast. The skid also has a support connector to attach to a second mast leg support of the drill rig mast and a substructure connector to attach to a substructure of a drill rig.

Abstract: A mast system includes a first leg of a mast pivotally connected to a pivot support and a second leg of the mast pivotally connected to a leg support. The leg support has a first support end with a surface connector to attach to a rig surface and a second support end with a leg connector to connect to the second leg to form a joint. A cable with a first cable end is attached to the leg support, and a force is exerted on the leg support through the cable that causes the leg support to rotate about the joint when the mast is lowered.

Abstract: A box substructure for a drill rig has a box frame including a medial side oriented towards a space located under a drill floor of the drill rig. A trolley structure is connected to the box frame and protrudes away from the medial side. The trolley structure also has an overhanging end opposite of the medial side.
