Liquid Loading In A Horizontal Shale Gas Well: Prediction, Prevention & Remediation
This GATEKEEPER article focuses on the prediction, prevention and remediation of liquid loading, including discussion of liquid loading analysis.
Collapse Strength Of Casing Subjected To Combined Load
Casing and tubing that are subjected to combined loads have higher collapse strength than previous formulas would predict, permitting the use of thinner walled, or lower strength, pipe than formerly required.
Collapse Strength of Casing Subjected to Combined Load
Triaxial evaluation of loads is used extensively for casing and tubing string design and analysis. The paper presents a method of determining the triaxially based collapse strength of casing and tubing subjected to simultaneous axial and internal pressure loads.
Wellbore Thermal and Mechanical Fingerprinting
A method is presented such that two parameters can be used to fully describe the thermal characteristics of a tubing string undergoing an injection or production process.
Real World Implementation of QRA Methods in Casing Design
This paper was prepared for presentation at the SPE Applied Technology Workshop on Risk Based Design of Well Casing and Tubing held in The Woodlands, Texas, U.S.A., 7-8 May 1998.
Designer Casing for Deepwater HPHT Wells
Deepwater high pressure, high temperature (HPHT) drilling environments present difficult challenges to well engineers.
LRFD Derived Performance of a Qualified API Connection Population
This work is a discussion of how the limit performance is being defined and quality systems are being revised for API connections in accordance with the objectives of the LRFD method for OCTG.
Annular Pressure Buildup: What It Is and What To Do About It
When tubing heated by hot formation fluids contacts colder fluids entrapped in the annulus, the result is fluid heating and pressure buildup. Proper well design is critical in subsea wells.
Advanced Technology Solutions for Next Generation HPHT Wells
This paper describes research efforts and technology development associated with the next generation of high pressure, high temperature (HPHT) well designs.
