GEOS attached great importance to environmental awareness and invested in waste management systems that focuses on reducing drilling waste at source and reusing it further in drilling and non-drilling related activities.
Drilled cuttings, drilling fluids on cutting, discharged drilling fluids, drilling fluid losses on surface, rain water and waste water used for cleaning and cooling are classified as drilling waste. An effective drilling waste management strategy is required for eliminating as much drilling waste going to landfill as possible, maximizing recovery and reuse of material at source.
We work closely with our clients, construction companies and rig contractors to optimize solids control and waste management system configurations based on project needs.
GEOS’s waste management system relies on the hierarchy below
Project specific wellsite construction
Drilling fluids discharge by efficient solids control
Drilling fluids by recovering from wet drilled cuttings
Water by Dewatering and maximizing water recovery from waste and rain water
Waste with chemicals for stabilization
Waste - Waste transportation & Disposal
