US 2020/0399989 A1 · EVALUATING HYDRAULIC FRACTURING BREAKDOWN EFFECTIVENESS

Abstract

The disclosure improves the analysis of the hydraulic fracturing (HF) break down process of a well system. The analysis can use as inputs collected HF data such as the HF fluid pressure, HF fluid flow rate, and HF fluid composition over one or more time intervals. In some aspects, the perforation parameters and stratigraphic well placement can also be used as inputs. The analysis can also use as inputs the HF model inputs that were used in collecting the HF data. The analysis can determine an effectiveness parameter of the received inputs. HF model inputs can be selected that would best fit a HF job plan goal for the current well system. In some aspects, the HF model inputs can be communicated to a well system controller of the current well system to further direct HF job plan operations.

Dependent claims

A method to determine a hydraulic fracturing (HF) job plan for a current well system, comprising:

receiving HF data and corresponding HF model inputs for one or more previous well systems, wherein the previous well systems contain a similar subterranean formation as the current well system, and wherein the HF model inputs include, over a time interval, at least one of a HF fluid pressure, a HF fluid flow rate, and a HF fluid composition;
calculating a fitted function utilizing an analysis of a HF breakdown within each of the previous well systems utilizing the HF data;
computing an effectiveness parameter for each of the fitted functions and the HF model inputs;
selecting HF model inputs utilizing the effectiveness parameter;
and
modifying the HF job plan utilizing the HF model inputs.
