In water-wet gas storage reservoirs, the imbibition force promotes the retention of water in the pore space, which curtails the deliverability of gas to the wellbore during periods of high demand. Similarly, the injection of gas during the fill cycle…
A comprehensive review of the technology currently used by the industry has been prepared and storage field operators assessments of the relative costs and benefits of the deliverability enhancement techniques being used have been obtained. A…
A parametric study was performed to investigate the effects of numerous well and reservoir parameters on gas well productivity. GMODl, an analytical model for gas production in homogeneous reservoirs, was used to calculate production data for more…
This report summarizes results of a horizontal gas storage well field experiment at the Howell Storage Field in Howell, Ml. A new horizontal well was successfully drilled in the Niagaran formation offsetting a vertical well on the same location. TVD…
This Final Report summarizes the results of a project to develop a preliminary screening process to assist reservoir engineers in evaluating various gas reservoir prospects. A gas reservoir screening program was developed during the project. Designed…
Each year, more than 17,000 gas storage wells in the United States lose from 3–5% of their storage capacity and deliverability. In addition, the gas storage industry spends $80–100 million annually to revitalize existing wells
This report summarizes the test results of a joint horizontal gas storage well field experiment undertaken at the West Edmond Storage field in Oklahoma. An existing vertical well with 7-in. casing set through the Red Fork sand was plugged and…
This report identifies, classifies, and illustrates the importance of a number of reservoir, operational, and well design parameters that are likely to strongly influence horizontal well performance in gas storage reservoirs. The objective of this…
The problem of unsteady-state flow of gas in porous media is not new to research workers. They have, by analogy, arrived at approximate solutions to the classical unsteady-state gas flow equation. Some have used heat flow formulas to accomplish their…
The primary aim of this study is to addresses this specific question. In addition, this study also establishes techniques to conduct cost-benefit analyses on deliverability enhancement treatments, quantitatively determine the impact of operational…
