US 2021/0277760 A1 · ENHANCING SUBTERRANEAN FORMATION STIMULATION AND PRODUCTION USING TARGET DOWNHOLE WAVE SHAPES

Abstract

The embodiments herein relate generally to subterranean formation operations and, more particularly, systems and methods for achieving target downhole pressures having target downhole wave shapes for enhancement of subterranean formation stimulation and production. In particular, a treatment fluid is introduced into a subterranean formation and a downhole pressure wave in the subterranean formation having a downhole wave shape is determined, and a surface pressure wave having a surface wave shape is determined. The downhole wave shape and the surface wave shape are compared, followed by adjustment of the surface pressure to achieve a target downhole pressure wave in the subterranean formation having a target downhole wave shape. The target downhole pressure and target downhole wave shape may be selected to maximize production of the subterranean formation.

Dependent claims

A method comprising:

(a) introducing a treatment fluid into a subterranean formation at a surface pressure above a fracture gradient of the subterranean formation to create or enhance at least one fracture therein at a first target interval;
(b) determining a downhole pressure wave in the subterranean formation, the downhole pressure wave having a downhole wave shape;
(c) determining a surface pressure wave at a surface location, the surface pressure wave having a surface wave shape;
(d) comparing the downhole wave shape and the surface wave shape;
and
(e) adjusting the surface pressure at the surface location to achieve a target downhole pressure wave in the subterranean formation, the target downhole pressure having a target downhole wave shape.
