GB Tubulars Test Summaries

This report summarizes a resonant Fatigue Test performed on 7" OD, 26.00 ppf, P-110 Casing finished with GB CD (Casing Drilling) Connections. The test was performed to determine fatigue life of this casing/connection combination in a test frame simulation of rotating through a 14° per 100-ft. build section.

This document summarizes the testing performed to qualify GB DWC Connections for ConocoPhillips which has particular interest in fatigue resistant connections for Drilling with Casing operations in their South Texas Lobo Field.
