Patent number: 5213168Abstract: A curve drilling assembly operable with a rotary drill string is provided for drilling a curved subterranean borehole. The assembly includes a curve guide, a rotary drill bit, an imbalance force assembly, and a bearing assembly. The curve guide is connectable with the drill string for deflecting the drill string toward the outside radius of the curved borehole. The imbalance force assembly, which preferably is provided by selectably disposing cutting elements on the drill bit, is rotatable with the drill string for creating a net imbalance force along a net imbalance force vector substantially perpendicular to the longitudinal axis of the drill bit during drilling. The bearing assembly is rotatable with the drill string and is located in the curve drilling assembly near the cutting elements of the drill bit for intersecting a force plane formed by the longitudinal bit axis and the net imbalance force vector and for substantially continuously contacting the borehole wall during drilling.Type: GrantFiled: November 1, 1991Date of Patent: May 25, 1993Assignee: Amoco CorporationInventors: Tommy M.

Patent number: 4837753Abstract: Method and apparatus for logging a borehole of the type in which an acoustic energy signal scans the borehole wall at a plurality of different depths thereby generating signals reflected from a reflecting boundary which are indicitative of the condition of the reflecting boundary. A downhole microcomputer generates a sync signal for firing a transducer thereby directing an acoustic pulse toward the borehole wall. The transducer is rotated by a stepper motor. The computer synchronizes the number of transducer pulses with the number of stepper motor pulses thereby generating a constant number of transducer pulses per motor revolution. Reflected acoustic energy generates an electrical pulse which is amplified and summed with a signal relating to the rotational orientation of the transducer and the occurrence of the transducer firing pulse. The summed signal provides information relating to the condition of the reflecting boundary and may be used to generate a video image thereof.Type: GrantFiled: April 10, 1987Date of Patent: June 6, 1989Assignee: Amoco CorporationInventors: Steven A. Morris, Houston B. Mount, II, John T. Penn

Patent number: 4802145Abstract: An apparatus and method of use thereof are disclosed herein for determining cement conditions adjacent a casing set within a wellbore. At least one acoustic transmitting and receiving transducer and at least one acoustic receiving transducer are positioned into contact with the interior surface of the casing. At least one pulse of acoustic energy is transmitted into the media surrounding the wellbore from the at least one acoustic transmitting and receiving transducer. Electrical signals are generated in response to acoustic energy received by both transducers from the surrounding media. Representations of the generated electrical signals are recorded as a function of the depth within the wellbore and are indicative of the cement conditions, including the casing-cement bond, the cement-formation bond, cement thickness, and the acoustic velocity associated with the cement.Type: GrantFiled: May 26, 1988Date of Patent: January 31, 1989Assignee: Amoco CorporationInventor: Houston B.

Patent number: 4774573Abstract: Apparatus for creating a video display from information generated by acoustically scanning a reflecting boundary circumferential of a borehole. A downhole tool generates a first signal each time a rotating transducer therein passes through magnetic north. Acoustic pulses emitted from the transducer are radially transmitted toward a borehole reflecting boundary. At least a portion of each pulse is reflected back to the transducer where the same is detected and converted to an electrical pulse representative of the reflected acoustic pulse. The peak of each electrical pulse is detected and the value digitized. A series of different addresses is associated with each digital value from a single 360.degree. borehole scan and the same are accumulated in a RAM with each digital value being stored therein at its associated address. A central processing unit selects a block of video memory locations in a video memory responsive to the magnetic north signal.Type: GrantFiled: April 10, 1987Date of Patent: September 27, 1988Assignee: Amoco CorporationInventors: Houston B.
