Abstract: A service tool and methods for performing subterranean hydrocarbon services in a wellbore. The service tool can include a body that having an aperture formed therethrough. A valve system can be connected to the body. The valve system can selectively form a flow path between a first portion of the aperture and a second portion of the aperture; a flow path between a first flow port formed through a first portion of the body, the aperture, and the outer diameter of the body; and/or a flow path between a channel formed in a portion of the body, a second flow port formed through a second portion of the body, and the second portion of the aperture.

Abstract: A technique facilitates sand control in a wellbore. A lower completion and an upper completion are run downhole into the wellbore and deployed. The lower completion assembly employs a plurality of packers to isolate well zones. The lower completion assembly also has gravel pack ports which are independently opened to enable gravel packing of each individual zone via a tool run downhole. Additionally, the lower completion assembly has a production port in each zone. A shifting tool is employed to open the production ports and to enable production from the well zones.

Abstract: A method for the automated analysis of digital images, particularly for the purpose of assessing mitotic activity from images of histological slides for prognostication of breast cancer. The method includes the steps of identifying the locations of objects within the image which have intensity and size characteristics consistent with mitotic epithelial cell nuclei, taking the darkest 10% of those objects, deriving contours indicating their boundary shape, and smoothing and measuring the curvature around the boundaries using a Probability Density Association Filter (PDAF). The PDAF output is used to compute a measure of any concavity of the boundary—a good indicator of mitosis. Objects are finally classified as representing mitotic nuclei or not, as a function of boundary concavity and mean intensity, by use of a Fisher classifier trained on known examples. Other uses for the method could include the analysis of images of soil samples containing certain types of seeds or other particles.

Abstract: A rotary drill bit for use in drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, a number of blades formed on the leading face of the bit and extending outwardly away from the axis of the bit so as to define between the blades a number of fluid channels leading towards the gauge region, a number of cutting elements mounted side-by-side along each blade, and a number of nozzles in the bit body for supplying drilling fluid to the fluid channels for cleaning and cooling the cutting elements. In each of the fluid channels, adjacent the gauge region, is an opening into an enclosed passage which passes internally through the bit body to an outlet which, in use, communicates with the annulus between the drill string and the wall of the borehole being drilled. The gauge region of the drill bit comprises a substantially continuous bearing surface which extends around the whole of the gauge region.

Abstract: A folding device for folding a sheet of thin material, such as paper, comprises a first sheet holder for holding a first portion of the sheet, a second sheet holder for holding a second portion of the sheet, and a pivoted linkage connecting the first sheet holder to the second sheet holder in such a way as to allow relative movement between them. In use relative movement between the holders causes the sheet to be folded in opposite directions along two lines so as to form a zig-zag shape.

Abstract: A rotary drill bit for drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, and a plurality of blades formed on the leading face of the bit body and extending outwardly away from the axis of the bit towards the gauge region so as to define a fluid flow channel between the leading edge of each blade and the trailing edge of the adjacent preceding blade. A plurality of cutting elements are mounted along the leading edge of each blade, and there is provided, in one or more of the channels, a main nozzle which directs fluid along the leading edge of one blade so as to clean and cool the cutting elements on it, and a subsidiary nozzle which is located and orientated so as to direct fluid along the trailing edge of the preceding blade in a direction opposite to the direction of flow from the main nozzle, so as to tend to enhance partial recirculation of fluid flow in the flow channel between the blades.

Abstract: A drill bit for drilling a borehole with a steerable drilling system, the drill bit comprising a longitudinal axis, and a cutting profile with a leading face section blended with a curved region into a tapered gauge region having a tapered gauge profile. The tapered gauge region being tapered with respect to the longitudinal axis determined by the steerable drilling system. The cutting profile and the gauge profile lie wholly within a bit profile envelope made up of a three dimensional surface of two complimentary conical sections set at the tilt angle and separated by and blended with a rounded section which forms an outermost diameter of the bit profile envelope. The rounded section has a diameter substantially equal to a maximum allowable API diameter for the drill bit, and further has a radius of curvature substantially equal to one-half the diameter.
