Drilling fluids storage ponds
In Geotechnical engineering, drilling fluid is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. The main functions of drilling fluids include providing Hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole.
A prime objective in all drilling operations is to minimize safety and environmental risks, while maintaining drilling performance.Operators and service companies alike take a proactive stance to reduce the potential for hazardous incidents. So there is always a need for sealed ponds in which Drilling fluids are kept and therefore earth pollution is prevented. Geomembranes are extensively used for construction of theses sealed ponds.
