Significant volumes of metallic waste (swarf) can be generated during slot recovery operations which typically requires the removal of a section of the original casing, usually by milling, prior to drilling a side-track to access a new production zone. Large volumes of swarf waste can also be produced when decommissioning a well where access to the annulus usually involves milling through the casing as part of the plug and abandonment activity. The reliable separation and removal of the milled metal swarf helps to prevent unnecessary damage to rig processing equipment, minimising the risk of rig downtime, whilst also allowing for the re-use of recycled drilling fluid. A safe, reliable and efficient means of removing metallic waste at surface, without the need for human intervention, is therefore a critical pre-requisite for most Operators and Drilling Contractors.
The ROMAR Solution
The ROMAR Swarf Handling System has been developed in-house by our own engineering staff and incorporates the cumulative knowledge, experience and operational expertise amassed over several years as a specialist provider of magnetic separation technologies to the oil and gas industry. The system has been designed with efficient metal particle separation and manual handling safety as the main considerations in order to provide a safe, highly efficient solution for the processing of liquids or slurries contaminated with metallic particles. The ROMAR Swarf Handling System involves a three stage swarf separation and recovery process, two of which involve the use of ROMAR’s patented magnetic separation technology to ensure the effective removal of metallic contaminants from the drill fluid. We have recovered over 1,000,000 Kg of swarf from over 100 wells worldwide with an unrivalled safety and service quality record.
