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 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 MAIntEnAnCEScomi Oiltools also has highly skilled staff to ensure equipment are correctly installed, fully operational and well-maintained. 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 MAnAGEMEntIn 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.
