UK-based engineering and technical services business RSK Group acquired Drilling Supplies & Hire Services, a supply and engineering company that services the site investigation, geothermal and water well markets across the UK. Financial terms were not disclosed. By joining forces, RSK will now be able to source site consumables and drill tooling in house for its services in the UK and abroad. As part of RSK’s contracting division under the direction of Claire Knighton, Drilling Supplies & Hire Services will remain a supply-only company and will not be involved in contractual or site work. “RSK has already developed a close business relationship with Drilling Supplies & Hire Services and I am excited to develop this relationship further now that it is part of the RSK group,” Alan Ryder, RSK founder and CEO.
