Scomi Oiltools Realising Potential. OUR STRATEGY Scomi Oiltools Drilling Waste Management Services reduce the waste generated during drilling activities to acceptable environmental levels. Our waste management services are based on our Waste Management Hierarchy which governs the way we deal with solids control and waste disposal, in all of our drilling activities worldwide. In its basic form, this hierarchy is divided into four levels: reduction at source recycling treatment disposal To ensure that these steps are adhered to, accurate planning, which takes into account both environmental protection as well as cost-effectiveness, is imperative. This involves studies to review both the project and the disposal criteria. Ultimately, the methods employed follow the Best Practicable Environmental Option (BPEO) and Best Available Technology Not Entailing Excessive Cost (BATNEEC) practices. Installation, Operation and Maintenance Scomi Oiltools has highly skilled staff to ensure that our equipment is correctly installed, fully operational and wellmaintained. Our employees are on-call worldwide, 24 hours a day, everyday and are trained to provide support at a moment s notice. In addition, our company carries comprehensive spares in numerous stocking locations to ensure minimum disruption or down-time to our clients operations arising from any technical incidents. Project Management In order to achieve specific objectives within a specified timescale and budget, Scomi Oiltools has developed a clear and concise Drilling Waste Management Programme. This programme, which is available to clients as a whole or in parts (according to clients needs), enables us to: identify waste streams, discern performance indicators and offer the best, cost-effective technical solutions and resources available. determine the best methods for safe and healthy operational practice and management controls. provide our clients with a report on specific performance data that includes recommendations for future improvements.
