(4.2) CASING EXTERNAL/INTERNAL COLD CUTTERS
We are delighted to introduce our Split Frame Cold Cutting tools used mostly in cutting and preparing pipe end for wellhead installation and other fire field weld preparation. This is an integral aspect of the Well head services, but can be carried out as stand-alone service for Clients, who have such specific need.
In addition to eliminating the need for hazardous flame cutting, the cold cutting method enables operators to meet all potential requirements, both onshore and offshore.
Our cold cutting system produces a lathe-type beveled finish on casing ends without altering metallurgical properties. Cutting equipment quickly splits to mount to casing O.D. and requires minimal radial and axial clearance. The cold cutter can be set up and operational in less than
30 minutes. Stonewall cold cutters are portable, lightweight and compact, allowing for easy transport of equipment to tubular yards and to the wellsite.
(4.3) WELLHEAD INTEGRITY SURVEY & MANAGEMENT
Stonewall supports its customers in delivering hydrocarbons safely throughout the life of their wells, through smarter well integrity management, supported by a comprehensive range of well service, cased hole evaluation, well intervention and remedial services.
With a strong emphasis on preventative well integrity management systems, our consultants and engineers provide a highly responsive service to meet your full range of well integrity needs with clear objectives of maximizing well availability and productivity while minimizing regulatory and HSE risks.
Services provided ranges from assessment of existing well integrity management system; the design, implementation and management of a new well integrity management system; through to the planning and execution of any well site services required to assess or remediate your wells.
These capabilities are relevant throughout the entire well lifecycle, from initial design through to eventual abandonment.
