The summer 2000 founding of the TU-CTMRC was based on successful coiled tubing mechanics research conducted at The University of Tulsa since 1989. This has included groundbreaking work on plasticity and fatigue modeling and measurement as well as 2 Joint Industry Projects (JIPs) focused on specialized areas of study:
Over 1,400 tests have been conducted on tubing samples using two unique CT test fixtures.
Data from these tests facilitated the accurate modeling of CT ballooning and elongation under
complex, realistic loading histories. Detailed information about fatigue damage accumulation
have been used to tune CT fatigue life prediction algorithms. These routines are in use all
over the world to monitor the structural integrity of strings throughout their entire life.
Data from samples with defects have led to new and interesting discoveries about the factors
that control their influence on fatigue.
