Abstract: An electric submersible pump contains an AC permanent magnet motor having three or more phases A, B, C and has a drive circuit for supplying varying drive signals to all the phases of the motor at the same time. Each drive signal is constituted by a cyclically smoothly varying voltage applied to the corresponding motor phase during driving of the motor. The circuit comprises switches (902, 903) for each motor phase, a control arrangement for turning the switches (902, 903) on and off at a frequency greater than the frequency of the cyclically smoothly varying voltages, and a filter (907, 908) for filtering the output voltages of the switches (902, 903) to produce the cyclically smoothly varying voltages. Such a drive circuit drives all the phases of the motor continuously such that damaging transients will not arise and without requiring the motor emf or drive signals to be sinusoidal.

Abstract: Improved methods and apparatuses for directly monitoring well casing strain and structural integrity are disclosed that allows for monitoring of potentially damaging strain from any orientation or mode and over long stretches of well casing. In a preferred embodiment, optical fiber sensors are housed within a housing and attached to the exterior surface of the casing. The sensors may be aligned parallel, perpendicular, or at an appropriate angle to the axis of the casing to detect axial, hoop, and shear stresses respectively. The sensors are preferably interferometrically interrogatable and are capable of measuring both static and dynamic strains such as those emitted from microfractures in the well casing. Analysis of microfracture-induced acoustics includes techniques for assessment of relatively high frequencies indicative of the presence of microfractures. Assessment of the timing of the arrival of such acoustics at various sensors deployed along the casing further allows for the location of strain to be pinpointed.

Abstract: A gripping apparatus (100) for supporting a tubular includes a longitudinal opening extending therethrough. A bowl (25) is formed on an inner wall of the housing to provide an incline surface for one or more gripping members (20). As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions (11, 12) coupled together using one or mores hinges (35). In one aspect, the bowl is formed as a recess in the inner wall (42) of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus.

Abstract: An expandable threaded connection between segments of expandable tubulars provides multiple sealing points along the pin and box members (10, 20) that can withstand high pressure. A gap (a) is utilized that is created between the pin nose (31) and the back (32) of the box member (20) when the threaded connection is made up and a reverse trapping angle ( θ ) machined into the pin nose end (32) and the back (32) of the box (20). The radial expansion of the tubulars causes axial movement of the pin nose (31) and the box member (20) until the pin nose (31) is in contact with the back (32) of the box member (20), thereby closing the gap (a) and forcing the pin nose (31) into sealing engagement with the back (32) of the box member (20). The reverse trapping angle ( θ ) forces the nose (31) of the pin member (10) outwardly ( i.e., toward the outer diameter of the expandable tubular string) as it is forced into contact with the back (32) of the box member (20) during the expansion process. The force imparted on the pin nose (31) by the reverse trapping angle ( θ ) creates a high pressure radial seal between surfaces of the pin member (10) and the box member (20). The contact point between the nose (31) of the pin member (10) and the back (32) of the box member (20) creates a high pressure axial seal. By controlling the initial gap size (a) and the reverse trapping angle ( θ ), it can be ensured that the axial and radial sealing points are strengthened by the expansion process. The combination of the radial and axial seals created by the expansion process provides an expanded threaded connection that is capable of withstanding high pressure.
