Abstract: A method for heating/removing and/or preventing solids in onshore or subsea pipe or wellbore tubular includes pumping a solution or suspension containing carbon nanotubes (CNT) and/or CNT based derivatives into the pipe or wellbore to a position proximate the solids and applying electromagnetic energy or electric current at one or more selected frequencies to the pipe proximate the solution. The pipe or wellbore tubular itself may be pre-coated with carbon nanotube containing material and exposed to radio frequency energy, microwaves, and electric current upon formation of solids therein.

Abstract: A method for characterizing subsurface formations penetrated by a wellbore includes accepting as input to a computer measurements of a physical parameter of the formations made over a selected axial interval of the wellbore. At least one attribute of the measurements is determined from a change in the measurements over the selected axial interval. At least one characteristic of the formations in the selected axial interval using the at least one attribute.

Abstract: A method for removing acid-gases from water includes introducing acid into a flow of aqueous solution having acid-gases and associated conjugate bases having an initial pH to lower the pH. The lowered pH solution has a stripping gas passed therethrough, resulting in a vapor phase of liberated acid-gas and stripping gas vapors, and a liquid phase comprising a lower concentration of acid-gases and associated conjugate bases than the aqueous solution. The liberated acid-gas and stripping gas vapors are collected and treated to remove acid-gas components, resulting in clean stripping gas product. The liquid phase is separated and collected with a second treating step, resulting in a final aqueous product having a lower concentration of acid-gases and associated conjugate bases than the liquid phase.

Abstract: Methods and systems of enhanced carbon dioxide recovery from an inlet gas stream are provided, by introducing the gas stream to one or more membrane-based separation units to produce a permeate byproduct gas stream having increased concentration of carbon dioxide compared to the inlet gas stream and then introducing the permeate byproduct gas stream to one or more pressure swing adsorption units or trains to enhance recovery of hydrocarbons, such as methane, lost in the byproduct stream and to produce a substantially pure carbon dioxide stream, while minimizing process compression and eliminating process heat for process regeneration. The methods introduced herein are for enhancing product recovery by enhancing carbon dioxide recovery from gas streams with pressures greater than atmospheric conditions. Further refinement to the methods would be the introduction of hydrogen sulfide polishing units within the process to produce product that meets or exceeds sales quality specifications.

Abstract: A system for cementing a wellbore penetrating an earth formation into which a pipe extends. A cement material is positioned in the space between the wellbore and the pipe by circulated capsules containing the cement material through the pipe into the space between the wellbore and the pipe. The capsules contain the cementing material encapsulated in a shell. The capsules are added to a fluid and the fluid with capsules is circulated through the pipe into the space between the wellbore and the pipe. The shell is breached once the capsules contain the cementing material are in position in the space between the wellbore and the pipe.
