Method for evaluating shaped charge perforation test cores using computer tomographic images thereof
Patent number: 8590382Abstract: A method for determining effects of perforation on a rock formation includes obtaining a sample of the rock formation. A perforation tunnel is created in the sample of the rock formation. The core sample is either subdivided into subsamples and a three dimensional tomographic image is made of each subsample and/or a three dimensional tomographic image is made of the sample of rock formation and the image thereof is segmented into sub images of selected subvolumes of the rock formation sample. At least one physical property of the rock formation is estimated from each tomographic image.Type: GrantFiled: July 19, 2010Date of Patent: November 26, 2013Assignee: Ingrain, Inc.Inventors: Theodore E. Zaleski, Jr., Avrami S. Grader, Henrique Tono -
Patent number: 8583410Abstract: A method and system for obtaining a consistent and integrated set of physical properties of a sample specimen of porous media, e.g., rock, in which a specimen is prepared for imaging. The specimen is imaged multiple times to yield a set of images that undergo a segmentation process to provide a digital representation of the sample specimen. The digital representation provides a view of the solid phase and pore space of the sample specimen. The digital representation may be used to determine a plurality of physical properties of the sample porous specimen, such that the sample porous specimen may remain intact throughout the method.Type: GrantFiled: May 28, 2010Date of Patent: November 12, 2013Assignee: Ingrain, Inc.Inventors: Carl D. Sisk, Theodore E. Zaleski, Jr.

Patent number: 8172008Abstract: A rotary drilling apparatus and method for drilling subterranean formations, including a body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation, so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per rotation of the drilling apparatus, as well as to control the amount of torque experienced by the drilling apparatus and an optionally associated bottomhole assembly regardless of the effective weight-on-bit are all disclosed. The exterior of the drilling apparatus may include a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the drilling apparatus against the bottom of the borehole without exceeding the compressive strength of the formation rock.Type: GrantFiled: September 29, 2011Date of Patent: May 8, 2012Assignee: Baker Hughes IncorporatedInventors: Mark W. Dykstra, William Heuser, Michael L. Doster, Theodore E. Zaleski, Jr., Jack T. Oldham, Terry D. Watts, Daniel E. Ruff, Rodney B. Walzel, Christopher C. Beuershausen
