Abstract
Provided is a cutting element, a drill bit, and a well system. The cutting element, in one aspect, includes a cutting section, the cutting element including a cutting section thickness (tc) and a cutting face. The cutting element, according to one aspect, further includes two or more shaped cutting features extending from the cutting face, wherein each of the two or more shaped cutting features is convex shaped, but also angles inwardly and downwardly from a radial exterior point of its shaped cutting feature to a radial interior point of its shaped cutting feature.
Claims23
A cutting element, comprising:
- a cutting section, the cutting section including a cutting section outer perimeter edge and a cutting section CenterPoint (CP) defining a distance (d), a cutting section thickness (tc) and a cutting face;
- and
- two or more shaped cutting features extending from the cutting face, wherein each of the two or more shaped cutting features is convex shaped having a peak and two edges, the peak angling continuously inwardly and downwardly from a radial exterior point of its shaped cutting feature to a radial interior point of its shaped cutting feature, wherein the two or more shaped cutting features come together proximate the CenterPoint (CP).
A drill bit, comprising:
- a bit body;
- one or more blades attached to the bit body;
- one or more pockets formed in the one or more blades;
- and
- one or more cutting elements fixed in the one or more pockets, wherein each cutting element includes:
- a cutting section, the cutting section including a cutting section outer perimeter edge and a cutting section CenterPoint (CP) defining a distance (d), a cutting section thickness (tc) and a cutting face;
- and
- two or more shaped cutting features extending from the cutting face, wherein each of the two or more shaped cutting features is convex shaped having a peak and two edges, the peak angling continuously inwardly and downwardly from a radial exterior point of its shaped cutting feature to a radial interior point of its shaped cutting feature, wherein the two or more shaped cutting features come together proximate the CenterPoint (CP).
A well system, comprising:
- a wellbore formed through one or more subterranean formations;
- and
- a drill bit located in the wellbore, the drill bit including:
- a bit body;
- one or more blades attached to the bit body;
- one or more pockets formed in the one or more blades;
- and
- one or more cutting elements fixed in the one or more pockets, wherein each cutting element includes:
- a cutting section, the cutting section including a cutting section outer perimeter edge and a cutting section CenterPoint (CP) defining a distance (d), a cutting section thickness (tc) and a cutting face;
- and
- two or more shaped cutting features extending from the cutting face, wherein each of the two or more shaped cutting features is convex shaped having a peak and two edges, the peak angling continuously inwardly and downwardly from a radial exterior point of its shaped cutting feature to a radial interior point of its shaped cutting feature, wherein the two or more shaped cutting features come together proximate the CenterPoint (CP).
