Abstract
A fluid used in a borehole containing suspended solid objects made by an additive manufacturing process. An additive process of solidifying a liquid composition at a succession of selected locations within a workspace, in accordance with a digital design allows a wide variety of shapes to be made. The fluid may be a drilling fluid or a borehole treatment fluid used prior to cementing and the objects may act, possibly in conjunction with other solids, to block loss of fluid into fractures in the formation around the borehole.
Claims20
A method of providing a borehole fluid containing suspended solid particles, comprising making solid objects by an additive manufacturing process, suspending the objects in a fluid and delivering the fluid into a borehole.
A method of inhibiting loss of borehole fluid into apertures in formation bounding the borehole, comprising making solid objects by an additive manufacturing process and suspending the objects in the borehole fluid to obstruct flow into the apertures.
