20130020134 | Fixed Cutter Drill Bit With Core Fragmentation Feature - A drill bit has a plurality of blades that include a coring blade, a plurality of flow courses that include an evacuation slot disposed between the plurality of blades, and a conical insert disposed on or proximate a bit centerline of the drill bit. Coring blade includes a first cutting element disposed at a first radial position from the bit centerline. Also, coring blade includes a substantially vertical surface and an angled surface. During drilling, first cutting element cuts formation to generate a core sample fragment at bit centerline. Core sample fragment is then broken away from formation using angled surface or conical insert after core sample fragment reaches a certain length. Core sample fragment then exits drill bit via an evacuation slot, from where core sample fragment is transported via an annulus to the surface of formation for testing and analysis. | 01-24-2013 |
20150068815 | FIXED CUTTER DRILL BIT WITH MULTIPLE CUTTING ELEMENTS AT FIRST RADIAL POSITION TO CUT CORE - A fixed cutter drill bit may include a bit body having a bit centerline; a plurality of blades extending radially from the bit body and separated by a plurality of flow courses therebetween, each of the plurality of blades being spaced a radial distance from the bit centerline to define a core-forming region; a plurality of cutting elements disposed on the plurality of blades, the plurality of cutting elements comprising at least two coring cutting elements disposed on the plurality of blades, the at least two coring cutting elements being the radially innermost cutting elements on the plurality of blades. | 03-12-2015 |
20150068816 | ORIENTATION OF CUTTING ELEMENT AT FIRST RADIAL POSITION TO CUT CORE - A fixed cutter drill bit may include a bit body having a bit centerline; a plurality of blades extending radially from the bit body and separated by a plurality of flow courses therebetween, each of the plurality of blades being spaced a radial distance from the bit centerline to define a core-forming region; a plurality of cutting elements disposed on the plurality of blades, the plurality of cutting elements comprising at least one coring cutting elements disposed on at least one of the plurality of blades, the at least one coring cutting elements being the radially innermost cutting element on the plurality of blades, wherein a coring angle of the coring cutting element is less than a inner cone angle thereof. | 03-12-2015 |
