SURFACE COMPLETION

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.

NuStar Technologies Multiple Completion Wellhead System allows the drilling and completion of multiple wells within a single conductor pipe. It integrates two compact wellhead and Christmas tree system into a main starter head assembly, to maximize the production output from a single slot.

NuStar Technologies Multiple Completion Wellhead System allows the drilling and completion of multiple wells within a single conductor pipe. It integrates three compact wellhead and Christmas tree system into a main starter head assembly, to maximize the production output from a single slot.

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.
