Abstract
Embodiments disclosed herein describe a rotating flow coupler that is configured to couple multiple sections of a casing for a horizontal well, wherein the rotating flow coupler is configured to rotate relative to the casing allowing an additional degree of freedom for equipment being lowered into the well. This may allow for equipment such as coil tubing, drilling string, casings strings, etc. to reach a total distance of deeper laterals.
Claims22
A rotating flow coupler configured to couple multiple sections of casing comprising:
- a first casing element;
- a second casing element;
- an outer tool with an outer diameter configured to be positioned proximate to sidewalls of a borehole, wherein the outer tool positioned between the first casing element and the second casing element;
- an inner tool configured to be positioned adjacent to an inner diameter of the outer tool, the inner tool configured to rotate relative to the outer tool, wherein the inner tool positioned between the first casing element and the second casing element;
- a first bearing positioned between the inner tool and the outer tool, the first bearing being configured to allow the inner tool to rotate relative to the outer tool while the outer tool remains fixed in place.
A rotating flow coupler configured to couple multiple sections of casing comprising:
- an outer tool with an outer diameter configured to be positioned proximate to sidewalls of a borehole;
- an inner tool configured to be positioned adjacent to an inner diameter of the outer tool, the inner tool configured to rotate relative to the outer tool;
- a first bearing positioned between the inner tool and the outer tool;
- and
- first crossovers configured to couple the outer tool to the multiple sections of the casing.
A method of utilizing a rotating flow coupler to couple multiple sections of casing, the method comprising:
- positioning an outer diameter of an outer tool proximate to sidewalls of a borehole, wherein the outer tool is positioned between a first casing element and a second casing element;
- positioning an inner tool adjacent to an inner diameter of the outer tool, wherein the inner tool is positioned between a first casing element and a second casing element;
- rotating the inner tool relative to the outer tool via a first bearing positioned between the inner tool and the outer tool while the outer tool remains fixed in place.
