(Quick Connect)

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.

The primary purpose of the wellhead is to provide the suspension point and pressure seals for the casing strings that run from the oil or gas reservoir to the surface pressure control equipment.

The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead.

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.
