Abstract
A gas extraction device includes a housing having a drilling fluid inlet and a drilling fluid outlet. A drilling fluid path can extend between the drilling fluid inlet to the drilling fluid outlet. Moreover, a plurality of drilling fluid disruptors, e.g., baffles, can be installed along the drilling fluid path. The drilling fluid disruptors liberate entrapped gas in the drilling fluid as the drilling fluid flows across the drilling fluid disruptors.
Claims20
A device for extracting gas from a drilling fluid, the device comprising:
- a housing having an exterior wall;
- a housing having a drilling fluid inlet and a drilling fluid outlet;
- a drilling fluid path extending between the drilling fluid inlet to the drilling fluid outlet;
- and
- a plurality of drilling fluid disruptors installed along the drilling fluid path, wherein the drilling fluid disruptors liberate entrapped gas in the drilling fluid as the drilling fluid flows across the drilling fluid disruptors.
A system for conducing subterranean drilling operations, the system comprising:
- at least one drill having a drill string and a drill bit;
- at least one pump for providing a drilling fluid to the drill string and the drill bit, the pump having an in-line and a return line;
- a bypass valve installed along the return line;
- and
- a gas extraction device connected to the bypass valve, wherein the bypass valve can be selectively opened to provide drilling fluid to the gas extraction device, wherein the gas extraction device tumbles drilling fluid within a housing of the gas extraction device to extract entrapped gas from the drilling fluid.
A method of extracting gas from a drilling fluid, the method comprising:
- bypassing a portion of a drilling fluid from a return line to a gas extraction device;
- tumbling the drilling fluid within the gas extraction device to release entrapped gas from the drilling fluid;
- and
- transmitting the entrapped gas to a test station for analysis.
