    Abstract: A method of re-processing used TSP material layers to form cutting elements, bits with such cutting elements mounted on their bodies, and bits having re-processed TSP material layers attached to their bodies, as well as such cutting elements and bits are provided. The method includes providing a used TSP material cutting element having a TSP material layer and substrate, or a bit having a TSP material layer attached to the bit, removing the used TSP material layer from the cutting element or bit, cutting the used TSP material layer to a new shape, if necessary, optionally re-leaching the used TSP layer and re-using the TSP material layer to form a cutting element, or in forming a bit body. The formed cutting element may be mounted on a bit body.

    Abstract: A bottom hole assembly containing a drill bit. The drill bit additionally has a plurality of primary cutter elements mounted thereto. The plurality of cutter elements comprise one or more first cutter elements and one or more second cutter elements. The second cutter element differs from the first cutter element in at least one cutter element property. The first cutter element has a diamond body containing a first region comprising an infiltrant material disposed within the interstitial regions. The first region is located remote from the working surface of the diamond body. The first cutter element also contains a second region comprising interstitial regions that are substantially free of the infiltrant material. The second region is located along at least the working surface of the diamond body. Also included are a cutter element, method of designing a bottom hole assembly as well as method of designing a drill bit.
