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…
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…
Through a partnership development with Gas Technology Institute (GTI) and Nucsafe, Inc., the goal of this project is to package patented RSD technology (“Radiography by Selective Detection of Scatter Field Velocity Components,” U.S. Patent 7,224,772,…
Technical report on a project intended to quantify natural gas losses in storage wells attributable to threaded casing connectors. Tests were conducted on a simulation apparatus of 5.5-inch K-55 casing using API 8 Round, Long, and Short threaded…
Casing corrosion in storage wells is a matter of considerable concern to the gas storage industry. Such wells are typically flowed through the casing rather than through production tubing, to facilitate high flow capacities. When failures occur, gas…
A considerable background of prior work indicates that corrosion damaged casing in gas storage wells is largely due to the development of individual corrosion pits, which occur either on the inside or outside wall of the casing. Such pits are…
Steel pipe casing used in underground gas storage is subject to corrosion primarily on the outside pipe surface. Corrosion in the form of pitting and wall thinning can cause serious maintenance and operational problems. Early detection and…
This report documents the work performed to evaluate the possibility that temperature log anomalies (“cold spots” or departures from temperature linearity with depth) can be indicators of well leaks. The natural gas cavern storage industry does not…
