Environmental, Health, and Safety Guidelines for Offshore Solids Control Equipments

Nov. 19, 2010 - PRLog -- Solid and liquid waste management Use of high efficiency solids control equipment to reduce the need for fluid change out and minimizing the amount of residual fluid on drilled cuttings.

Water-Based Drilling Fluids (WBDF): Fluids where the continuous phase and suspending medium for solids is seawater or a water miscible fluid. There are many WBDF variations, including gel , salt-polymer , salt-glycol and salt-silicate fluids; · Non-Aqueous Drilling Fluids (NADF): The continuous phase and suspending medium for solids is a water immiscible fluid that is oil-based, enhanced mineral oilbased, or synthetic-based.

Typically, the solid medium used in most drilling fluids is barite (barium sulfate) for weight, with bentonite clays as a thickener.
Drilling fluids also contain a number of chemicals that are added depending on the downhole formation conditions.

Drilling fluids are either circulated downhole with direct loss to the seabed along with displaced cuttings, particularly while drilling well sections nearest to the surface of the seabed, or are recirculated to the offshore facility where they are routed to a solids control system. In the solids control system, the drilling fluids are separated from the cuttings so that they may be recirculated downhole leaving the cuttings behind for disposal.
These cuttings contain a proportion of residual drilling fluid. The volume of cuttings produced will depend on the depth of the well and the diameter of the hole sections drilled.
