Drilling waste management options can be roughly grouped into three categories: offshore discharge, re-injection on-site, and onshore disposal. All three groups of waste management options come with their own set of advantages and limitations. A deeper understanding of the specifics of each technology is required for key stakeholders to make the best decisions in the regulatory process.
Offshore Discharge: Offshore discharge is in most cases the least expensive and operationally uncomplicated, of the three options. In evaluating the viability of this option, one must consider whether the fluid can meet regulatory requirements for discharge, the technical drilling requirements, and the potential environmental impact.
Onshore Disposal: If drilling wastes are not handled onsite either via discharge or CRI, they will need to be transported to shore for disposal. Consideration of any onshore disposal option must also include consideration of the offshore operations and transport associated with getting the drilling waste to shore. There are a number of environmental, operational, and economic disadvantages to the selection of onshore disposal. These operations require extensive use of support vessels to take the cuttings to a shore location.
GN Solids Control now can supply cutting dryer, hi-G shaker, and also have some good partners supplying screw conveyer, so this means now we can supply all the equipment for the whole drilling fluid plant.
In CIPPE 2012, we will show all the equipment in our booth, if you are interested, come to visit: E2216; if you need more information, email to sales@gnsolidscontrol.com
