A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing COinto an absorber; b) flowing the flue gas through an absorber having an absorbent with a water-lean solution having less than 50% water and one or more amines, with the absorbent capturing the COand forming a reduced COcontent gas having a baseline COcontent; and c) washing the reduced COcontent gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous COinto the wash solution. In this method, the washing removes the amines from the reduced COcontent gas and produces a reduced amine content gas exiting from the wash column.

Acid gas compounds are removed from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a COremoval unit to remove a substantial fraction of COfrom the desulfurized gas.

A cementing method includes positioning a bottom plug at a casing shoe, rupturing the bottom plug, signaling when a top plug reaches a target position, and releasing a chemical into a cement slurry below the top plug in response to the signaling. The signal may comprise a mechanical trigger changing its position due to movement of the top plug past the target position.

Cementing methods and systems employing a smart plug

The present disclosure relates to cementitious fluids comprising additives configured to form a permeable cement matrix after curing of the cement. The cementitious fluids can comprise a cementitious medium (e.g., a cement slurry) with a plurality of fibers dispersed therein. The fibers can be hollow, can be porous, and can be degradable. The cementitious fluid particularly can be used in methods of stimulating hydrocarbon bearing formations. Specifically, the cementitious fluid can be injected into the formation to form or enlarge a fracture, and the fluid can be cured to form the permeable cement matrix, said permeability arising from a loosely assembled tubular network and/or passages remaining after degradation of the fibers.

Cementitious fracture fluid and methods of use thereof

Systems and methods that utilize bremsstrahlung radiation may be used to facilitate the setting of a settable composition. For example, a method may include providing a settable composition in a portion of a wellbore penetrating a subterranean formation, a portion of the subterranean formation, or both; conveying an electron accelerator tool along the wellbore proximal to the settable composition; producing an electron beam in the electron accelerator tool with a trajectory that impinges a converter material, thereby converting the electron beam to bremsstrahlung photons; and irradiating the settable composition with the bremsstrahlung photons.

The present invention includes methods relating to the setting of fluids or slurries in a wellbore. In one embodiment, a method of isolating a portion a wellbore by preparing a sealant composition comprising a fluid component and a polymeric additive component, placing the sealant composition into a wellbore and subjecting the sealant composition to ionizing radiation. The ionizing radiation can cause bonding between polymeric additive components and create a polymer matrix within the sealant composition that increases the mechanical strength of the sealant composition.
