  • Publication number: 20140155738
    Abstract: An apparatus comprising a convex probe, a receiver and an image generating device. The convex probe includes a number of transducer elements configured to transmit a number of sets of ultrasound signals. Each set of the ultrasound signals includes a non-steered frame and at least one steered frame angled toward the non-steered frame. The receiver is coupled to the probe and configured to receive a non-steered echo frame for the non-steered fame and at least one steered echo frame for the at least one steered frame. The image generating device is coupled to the receiver and configured to generate a non-steered image using the non-steered echo frame and a needle-enhancement image using the steered echo frame and combine the non-steered image and the needle-enhancement image into a compound image.

  • Patent number: 8739874
    Abstract: Systems and methods for treating a subsurface formation are described herein. Some embodiments generally relate to systems, methods, and/or processes for treating fluid produced from the subsurface formation. Some methods include providing heat to a first section of the hydrocarbon containing formation from a plurality of heaters located in the formation; allowing the heat to transfer from the heaters to heat a portion of the first section to mobilize formation fluid; and producing formation fluid from the formation.

  • Patent number: 8561720
    Abstract: A method of steering a drill bit to form an opening in a subsurface formation, comprises a) determining a distance from design of a well, and b) determining an angle offset from design of the well wherein angle offset from design is the difference between the inclination and azimuth of the hole and the inclination and azimuth of plan, c) wherein at least one distance from design and at least one angle offset from design are determined in real time based, at least in part, on a position of the hole at the last survey, a position at a projected current location of the bit, and a projected position of the bit.

  • Publication number: 20130270005
    Abstract: A method of controlling a direction of drilling of the drill string used to form an opening in a subsurface formation, comprises varying a speed of the drill string during rotational drilling such that the drill string is at a first speed during a first portion of the rotational cycle and at a second speed during a second portion of the rotational cycle wherein the first speed is higher than the second speed, and wherein operating at the second speed in the second portion of the rotational cycle causes the drill string to change the direction of drilling.
