TechnipFMC has been awarded an additional contract and received notice to proceed by ExxonMobil affiliate Esso Exploration and Production Guyana Limited for its Yellowtail development in the Stabroek Block offshore Guyana.
High temperatures, high pressures and/or abrasive formations can make for unmanageable conditions. A proprietary MWD technology has been developed to endure harsher downhole environments than previous measurement logging tools.
As operators search for reserves in challenging HPHT environments, new technology is required to support these projects. An innovative expandable liner hanger, which offers a gas-tight metal-to-metal sealing system, is capable of superior hanging capacity for installing casing strings of various lengths.
New valves and piping designs mitigate the detrimental effects of HPHT conditions and extreme pressure drops, as well as severe erosion and caustic environments.
To navigate continually changing HPHT design and regulatory requirements, a collaborative approach is required. The team is qualifying a 20,000-psi rated BOP. Engineers are hopeful that the HPHT design process will reach the same level of standardization as today’s 15,000-psi equipment, after completion of this and similar qualification efforts.
Calculating the collapse strength of casing installed in HPHT wells is challenging due to the complexity of the casing’s geometrical and mechanical properties, as well as the loading conditions that can impact overall performance.
