A cyclic steam soak (CSS) stimulation method for producing heated hydrocarbons from a viscous hydrocarbon-containing formation comprises the steps of: a) drilling a well () having a substantially horizontal or inclined lower section () into the viscous hydrocarbon-containing formation () substantially along the trajectory of the minimum compressive horizontal stress Sh; b) cutting at selected intervals along the length of the lower well section () substantially disk-shaped cavities (A-D) into the viscous hydrocarbon-containing formation () by a rotating hydraulic jet cutting device (); c) completing the well (); d) injecting steam into the well () and disk-shaped cavities (A-D) at such an elevated pressure that the hydraulic pressure in at least one disk-shaped cavityA is above the formation fracturing pressure, thereby fracturing the formation () and permitting the steam to invade the formation surrounding the fracture and to heat hydrocarbons in the steam invaded zone; e) interrupting steam injection and producing heated hydrocarbons via the well (); and f) repeating steps (d) and (e) a number of times.

Cyclic steam stimulation method with multiple fractures

A system is provided for injecting an injection fluid into an earth formation via a wellbore formed in the earth formation and for producing hydrocarbon fluid from the earth formation via the wellbore. The system comprises an injection conduit extending into the wellbore and being in fluid communication with a plurality of outlet ports for injection fluid, and a production conduit extending into the wellbore and being in fluid communication with at least one inlet section for hydrocarbon fluid. The injection conduit is arranged to prevent fluid communication between the injection conduit and each said inlet section.

System for cyclic injection and production from a well

A system including a mechanism for recovering oil and/or gas from an underground formation, the oil and/or gas comprising one or more sulfur compounds; a mechanism for converting at least a portion of the sulfur compounds from the recovered oil and/or gas into a carbon disulfide formulation; and a mechanism for releasing at least a portion of the carbon disulfide formulation into a formation.

System and methods for producing oil and/or gas

A method is provided of reducing an amount of a waste component present in a hydrocarbon fluid produced from an earth formation via a wellbore formed in the earth formation, the hydrocarbon fluid flowing in a stream of fluid through the wellbore. The method includes (a) inducing at least part of the amount of the waste component to move into a second fluid present in the stream of fluid; (b) separating the second fluid with the at least part of the amount of the waste component included therein, from the hydrocarbon fluid; and (c) disposing the second fluid with the waste component included therein by injecting it into the earth formation via at least one of the wellbore and another wellbore formed in the earth formation.

Waste component removal from crude oil or gas

The invention relates to a method of reducing an amount of a waste component present in a hydrocarbon fluid produced from an earth formation via a wellbore formed in the earth formation, the hydrocarbon fluid flowing in a stream of fluid through the wellbore. The method includes the steps of: a) inducing at least part of the amount of the waste component to move into a second fluid present in the stream of fluid as the stream flows through the wellbore; and b) separating the second fluid with the at least part of the amount of the waste component included therein, from the hydrocarbon fluid.
