04/01/2017 - Oil&GasOCTG supplier perspective: Lessons Learned from supply to Extreme HPHT Projects
Case study 1 – A VAM® Connection Tailored to ApplicationAn HPHT well in Asia downhole conditions were at around 19000psi, 350degF, along with mild H2S exposure. The requirement was for the 125ksi production casing to withstand loads and be suitable in terms of weight requirements. The existing solution of 10 ¾" 110.2# VAM® HP SC 80 exceeded the performance requirements. The test data was already available per connection envelope and well loads. However, it was not suitable for the application due to dimensional constraints, and therefore a new OD and design were required.
Lessons Learned:Success requires active involvement from all partners at the initial stages. This process allows definitions of requirements to be clearly communicated, and highlights all aspects (testing, timing, contingency) along with 'risk' effect.
