Abstract
A system, in certain embodiments, includes a horizontal fracturing tree. The horizontal fracturing tree includes a first hydraulic fracturing bore configured to flow a first fluid, wherein the first hydraulic fracturing bore extends along a first horizontal axis, and the first horizontal axis is generally perpendicular to a vertical axis of a wellhead.
Claims22
A system, comprising:
- a fracturing tree, comprising:
- a lateral branch configured to couple to a wellhead, wherein the lateral branch comprises a first lateral flow path, wherein the first lateral flow path extends along a first axis, and the first axis is substantially perpendicular to a central axis of the wellhead;
- and
- a first connection operatively connected to the first lateral flow path, wherein the first connection comprises a first upward flow path that extends in an upward direction toward the first lateral flow path, wherein the first upward flow path extends a first length that is greater than half of a height from a ground level portion of the fracturing tree to the first axis of the first lateral flow path, wherein a first hydraulic fracturing flow path is configured to flow a hydraulic fracturing fluid in a flow direction through the first upward flow path, the first lateral flow path, and a downward flow path into the wellhead, wherein the lateral branch and the first connection are configured to reduce bending moments at least partially caused by connected piping.
1 more element
A system, comprising:
- a fracturing tree, comprising:
- a wellhead having a main bore extending along a central axis;
- a first lateral tree branch coupled to the wellhead, wherein the first lateral tree branch comprises a first lateral flow path, and the first lateral flow path extends along a first axis crosswise to the central axis;
- a first valve disposed along the first lateral flow path;
- and
- a first connection operatively connected to the first lateral flow path, wherein the first connection comprises a first upward flow path that extends in an upward direction toward the first lateral flow path, wherein a first hydraulic fracturing flow path is configured to flow a hydraulic fracturing fluid in a flow direction through the first upward flow path, the first lateral flow path, and a downward flow path into the wellhead, wherein the fracturing tree comprises at least one of:
- the first upward flow path extends a first length that is greater than half of a height from a ground level portion of the fracturing tree to the first axis of the first lateral flow path;
- or
- a first lateral length of the first lateral flow path is greater than half of the height.
6 more elements
A system, comprising:
- a fracturing tree, comprising:
- a lateral branch configured to extend laterally away from a wellhead, wherein the lateral branch comprises a first lateral flow path, wherein the first lateral flow path extends along a first axis crosswise to a central axis of the wellhead;
- and
- a first connection operatively connected to the first lateral flow path, wherein the first connection comprises a first upward flow path that extends in an upward direction toward the first lateral flow path, wherein a first lateral length of the first lateral flow path is greater than half of a height from a ground level portion of the fracturing tree to the first axis of the first lateral flow path, wherein a first hydraulic fracturing flow path is configured to flow a hydraulic fracturing fluid in a flow direction through the first upward flow path, the first lateral flow path, and a downward flow path into the wellhead.
1 more element
A method, comprising:
- routing a hydraulic fracturing fluid through a first lateral tree branch portion of a fracturing tree along a first hydraulic fracturing flow path between a main bore of a wellhead and a first connection, wherein the first connection is operatively connected to a first lateral flow path through the fracturing tree, wherein the first connection comprises a first upward flow path that extends in an upward direction toward the first lateral flow path, wherein the first upward flow path extends a first length that is greater than half of a height from a ground level portion of the fracturing tree to a first axis of the first lateral flow path, wherein the first hydraulic fracturing flow path flows the hydraulic fracturing fluid in a flow direction through the first upward flow path, the first lateral flow path, and a downward flow path into the wellhead.
