  • Weighted scrub brush
    Patent number: 7481594
    Abstract: A weighted scrub brush has a brush head defining a leading end, a trailing end, a pair of laterally opposing ends, a downwardly facing bristle support surface, and an upwardly opening weight recess. A weight having first and second opposing ends is removably positioned within the weight recess. Mating support members support the first end of the weight, while a cantilevered support latch partially overlaps the second end of the weight to secure the weight within the weight recess. A conduit extends from a liquid intake port, through the handle, and to the brush head to dispense liquid from the conduit to the plurality of bristles. A roller is secured to a central body portion of the brush head forward of the handle, such that the brush head may be pivoted to a forward, inverted position to roll the brush.

  • Method and apparatus for conducting earth borehole operations using coiled casing
    Patent number: 7481280
    Abstract: A method and apparatus for conducting earth borehole operations include a reel (28) of continuous coiled casing (30), and an injector (20) for moving the coiled casing. The bottomhole assembly including at least a motor (54) and a bit (56) is connected to the free end of the coiled casing, and injected into the earth while circulating fluid through the coiled casing to form a drilled earth borehole having a borehole wall. The coiled casing drill string may be retrieved from the borehole, the bottomhole assembly removed, and the coiled casing again injected into the borehole, then suspended from a wellhead assembly. After severing the coiled casing, a bonding agent such as a cementitious material may be injected into the suspended coiled casing and into the annulus between the coiled casing and the borehole.

  • System and method for producing fluids from a subterranean formation
    Patent number: 7451814
    Abstract: The system of subterranean wells includes a subsurface flow line 20 having at least a portion within or underlining one or more subterranean formations 12. One or more drainage wells 26, 28, 30, 32, and 34 each extend from the surface and intercept at least one of the subterranean formations at a respective interception location. A lower portion of each drainage well is in fluid communication with the subsurface flow line. A recovery well 42 extends from the surface and is also in fluid communication with the subsurface flow line, so that fluids entering the drainage well flow into the subsurface flow line and then into the recovery well.

  • Downhole flapper circulation tool
    Patent number: 7434625
    Abstract: The circulation tool 10 for use downhole in a well includes a housing 22 having one or more bypass ports 52 for circulation between a bore 33 in the housing and an annulus surrounding the housing. Sleeve 50 is axially movable within the housing, and axially spaced seals 36, 56 seal between the sleeve and the housing when the sleeve is in the closed position. A flapper 84 is pivotally mounted to the sleeve, and includes a seat about a central bore 85 in the flapper for engagement with the plug. A stop 40 prevents pivoting of the flapper to an open position until the sleeve has moved axially and the seals seal between the sleeve and the housing.
