Application of Advanced Stimulation Technologies in the Appalachian Basin: Field Case Study of Well Performance Several Years Later (SPE 51047)

Summary

In the Rose Run low permeability sandstone, wells were previously acidized and treated with less than 3 ppg 20/40 sand.  Ceramic proppant was not locally available, but wells fractured with up to 5 ppg sand showed excellent production and were among best wells in the field.

Abstract

From December 1993 through October 1996 the Gas Research Institute (GRI) and several local producers were involved in field case studies which applied Advanced Stimulation Technologies (AST). The objective of the studies was to demonstrate new and emerging technologies that would help the operators optimize hydraulic fracture treatment design, execution, and evaluation. The technologies were demonstrated by applying them to wells (study wells) in the areas of interest. The technologies demonstrated included coring, special logging, pre- and post-fracture welltesting, production data analysis, in-situ stress profiling, 3D hydraulic fracture design, real-time fracture diagnostics, and quality control (QC). For each study, a benefits analysis was performed by comparing production from the study wells to offset well production to determine if the application of the technologies was beneficial to the operators. All the studies showed some economic benefit to the operator in the form of increased production, reduced treatment costs, or a combination of both.
