NuStar Technologies Surface Wellhead Equipment are configurable to meet customers’ specific casing and drilling programs, for different well pressures (2,000 psi to 15,000 psi), well temperature ratings (K to U and X), well fluid conditions (Standard to Sour Service per NACE MR0175 requirements) etc.
The NuStar Compact Wellhead enables multiple casing and tubing strings to be suspended in a single wellhead housing. The benefit from such a compact wellhead shall be the reduction in number of times the BOP stack connection is detached and reattached thus saving significant rig time.
Surface wellhead consists of components at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
