Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system, comprising: a land-based horizontal fracturing tree, comprising: a first hydraulic fracturing bore configured to flow a first fluid, wherein the first hydraulic fracturing bore comprises: a horizontal flow path extending along a first horizontal axis; and a vertical flow path extending along a vertical axis of a wellhead, wherein a horizontal flow path length of the horizontal flow path is greater than a vertical flow path length of the…
