Protocol for Verification and Validation of HPHT Equipment

This report focuses on an evaluation process for HPHT equipment in the petroleum and natural gas industries which includes design verification analysis, design validation, material selection considerations, and manufacturing process controls necessary to ensure the equipment is fit-for-service in the applicable HPHT environment. where HPHT environments are intended to mean one or more of the following well conditions exist: a) the completion of the well requires completion equipment or well control equipment assigned a pressure rating greater than 15,000 psig or a temperature rating greater than 350°F; b) the maximum anticipated surface pressure or shut-in tubing pressure is greater than 15,000 psig on the seafloor for a well with a subsea wellhead or at the surface for a well with a surface wellhead; or c) the flowing temperature is greater than 350°F on the seafloor for a well with a subsea wellhead or on the surface for a well with a surface wellhead.
