Abstract
A cutting element includes a modified gilmoid having two planes defining a plurality of cutting edges thereon, and a first support extending from a central area of a first of the two planes and a second support extending from a central area of a second of the two planes. The supports are sized and positioned such that when the cutting element is resting against a planar surface such that one of the plurality of cutting edges and the first support are in contact with the planar surface the first plane forms an acute angle with the planar surface.

A cutting element, comprising
- a modified gilmoid having a plurality of surfaces two of which are planes, the two planes define a plurality of edges formed by intersections of the two planes with the plurality of surfaces of the modified gilmoid;
- and
- a first support extending from a central area of a first of the two planes and a second support extending from a central area of a second of the two planes, the first support being sized and positioned such that when the cutting element is resting against a planar surface due to gravity alone with one of the plurality of edges and the first support in contact with the planar surface, the first plane forms an acute angle with the planar surface.
An apparatus for drilling subterranean formations, comprising:
- a support surface;
- a plurality of cutting elements for placement on the support surface, wherein each of the plurality of cutting elements include a base defined as a modified gilmoid having a peripheral upper end edge defined by intersections of surfaces of the modified gilmoid with at least one of the surfaces defined as a first plane having at least one first lateral support extending therefrom and a peripheral lower end edge defined by intersections of the surfaces of the modified gilmoid with at least one of the surfaces defined as a second plane having at least one second lateral support extending therefrom wherein the peripheral lower end edge engages the support surface and the peripheral upper end edge is disposed at a distance from the support surface, the base having the at least one second lateral support extending therefrom such that random placement of the plurality of cutting elements on the support surface results in at least some of the plurality of cutting elements being positioned such that the peripheral lower end edge and the at least one second lateral support is simultaneously in contact with the support surface at spaced locations on the support surface.
A plurality of cutting elements configured for placement on a support surface, the plurality of cutting elements each comprising:
- a base having a peripheral upper end edge defined by intersections of surfaces of a modified gilmoid with at least one of the surfaces defined as a first plane having at least one first lateral support extending therefrom and a peripheral lower end edge defined by intersections of the surfaces of the modified gilmoid with at least one of the surfaces defined as a second plane having at least one second lateral support extending therefrom wherein the peripheral lower end edge engages the support surface and the peripheral upper end edge is disposed at a distance from the support surface, the base having the at least one second lateral support extending therefrom such that random placement of the plurality of cutting elements on the support surface results in at least some of the peripheral lower end edges and the at least one second lateral support being simultaneously in contact with the support surface at spaced locations on the support surface.
