The story of valves and actuators is one of changing demands. Over the course of history, valves have evolved to meet the needs of the user. In the oil and gas industry, valves met their toughest customers. This is increasingly true today.

Although the industry considers 15,000 psi and 350°F to represent “high-pressure/high-temperature” (HPHT) conditions, these are rapidly becoming the category’s lower limits. Since subsurface safety valves are the emergency fail-safe flow-controlling devices within a completion, they must have superior performance and reliability throughout a well’s life. Additional validation techniques must be employed to ensure robust, fit-for-purpose performance early in the development process.

Advances in exploration and drilling technology are enabling the oil and gas industry to target more complex reservoirs in extreme environments, requiring new designs for intelligent completion tools. A new generation of interval control valves (ICVs) that tolerate higher pressures and temperatures has been developed to cater to these harsher environments.

Shale gas development presents many flow-control challenges, requiring valves selected specifically for this environment. Conditions vary considerably from one shale basin to another, and effective valve design and selection criteria must consider HPHT and volume demands, as well as abrasive media and corrosion.
