  • SYSTEM AND METHOD FOR DECLUSTERING SUBSURFACE DATA ON A PER-SLICE BASIS
    Publication number: 20120084007
    Abstract: Wellbore data samples taken within a subsurface volume of interest are declustered. A weighting-based, interpolating technique is employed in a layer-based, two dimensional manner to separate slices within the subsurface volume of interest. The performance of declustering on a slice-by-slice basis may make the process less costly and/or may reduce certain artifacts or effects associated with subsurface data interpolation.

  • Shrinking balloon catheter having nonlinear compliance curve
    Patent number: 5403340
    Abstract: A balloon catheter, having a non-linear compliance curve, made up of a single layered balloon, that was molded from a polymeric material to have a specific nominal diameter and then shrunk to a diameter that is less than the specific nominal diameter. When the shrunk balloon is expanded it has the characteristics of a compliant balloon until its diameter has been expanded to its original specific nominal diameter after which it follows the non compliant compliance curve that it would have had it not been shrunk.

  • Shrinking balloon catheter having nonlinear or hybrid compliance curve
    Patent number: 5348538
