The research described in this report is focused on the dynamics of the brine strings utilized in solution-mined caverns. In Configuration 3, fluid enters the system from the top of the brine string and exits via the annulus between the brine string…
This report documents the development of a set of Guidelines for the use of subsurface safety valves in gas storage wells. The final version of the Guidelines is included in Appendix A at the end of the report. The Guidelines were formulated based on…
The purpose of the work is to assess the safety and operational advantages and establish guidelines for using subsurface safety valves in gas storage well applications.
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…
Brine solutions are often produced during gas storage operations, and when these solutions encounter changing temperature or pressure, salt can precipitate. This salt (NaCl) can impair productivity and may even result in abandonment of wells.…
An industry survey, dominated by PRCI member companies, was undertaken to gather key information regarding the design, operation and inspection of well bore casing strings. The aim of the survey was to gather information regarding the design…
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…
Design and construction of 5.5 inch prototype downhole inspection tool and electronics module. Implement preliminary software acquisition and display module. Integrate hardware and software systems. Conduct operational field test…
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…
