Circular Economy Applied to Synthetic Oil-Based Drilling Fluids


 Circular economy has become in the last decades one of the major subjects of debate for corporations around the globe. The ever-growing attention towards the environment and a more sustainable exploitation of the resources of the planet have led the major Oil Companies worldwide to reconsider their internal processes and approaches to business. In this context, the efforts aimed at identifying and implementing initiatives and operative processes pertinent to the concept of circular economy triggered to reconsider Synthetic (low-toxic) Oil-Based drilling fluids (muds) as one of the main actors in terms of successful operative circular initiatives in the oil business. Thanks to their inherent durability in time and scarce tendency to degrade, Synthetic Oil Based Muds unfold many opportunities of recycling and re-use which could not be possible with other drilling fluids systems. In this regard, a correct management of Oil Based drilling fluids which permits treatment, storage, and re-utilization in new wells of the same field or new projects, can significantly reduce the CO2 emissions related to drilling fluids life cycle.
 The aim of this paper is to quantitatively show the results that can be achieved in terms of reduction of emissions of greenhouse gases by the recycling of Synthetic Oil Based drilling fluids thanks to a considerable volume requirement decrease in relation to drilling operations, and the correlated utilization of resources.
