Abstract: A recursive method of optimizing rate of penetration while drilling a well. The method can include collecting historical data on a plurality of drilling parameters, performing a mathematical analysis on the historical data to correlate each drilling parameter to a rate of penetration, determining an importance of each drilling parameter, establishing an operating envelope for each drilling parameter, and adjusting at least one drilling parameter to achieve a desired rate of penetration. The steps can then be repeated at a user defined interval.

Abstract: A method for quantifying frac hits within a few days using a novel pressure-transient analysis technique called differential pressure-transient analysis (DPTA). Unlike pressure transient analysis (PTA) methods, focused on single-well analyses, DPTA evaluates pressure response from two or more wells simultaneously to (1) determine the existence of frac hits, and (2) determine the degree of interference, defined as the ratio of inter-connected to total number of primary fractures from a given well. The output from (2) can be subsequently used to accurately predict oil and/or gas production rates for infill and offset wells.

Abstract: An annular packer (10) for use with an annular blow out preventer (20) formed of a plurality of blades or elements (21,30,72) where each of the blades (21,30,72) is curved and arranged in the annular bore such that the curve of the blade is not parallel with the longitudinal axis of the assembly. This creates an “iris” type of geometry which, as the iris closes, the annular bore (24) transforms from a parallel cylindrical shape to a smaller bore with a shape having at least one waist or pinch point (32,34,73,75) of smaller cross-section.

Abstract: A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs. A first bidirectional power converter is employed in a sealed battery unit having no external electrical contacts. A second bidirectional power converter is employed in a corresponding cart bidirectional power converter assembly. The battery unit and the cart bidirectional power converter assembly cooperate to wirelessly transmit power from the battery unit to a load of the cart bidirectional power converter assembly and from a power source to the battery unit via the cart bidirectional power converter assembly.

Abstract: A power controller for an electrical load is disclosed. The power controller includes a power stage operable to selectively provide an output voltage to the load. An input voltage generator supplies an input voltage to the power stage. A hysteretic comparator is operable to compare a reference voltage to a feedback output voltage from the load, the feedback output voltage being at least a portion of the output voltage, and provide a hysteretic comparator output to the power stage which controls the output voltage. A synthesizing circuit is operable to generate a synthesized voltage and couple the synthesized voltage with the feedback output voltage before the feedback output voltage is compared with the reference voltage by the hysteretic comparator. Coupling of the synthesized voltage with the feedback output voltage synchronizes the hysteretic comparator output with the input voltage provided to the power stage.

Abstract: The invention relates to an apparatus (10) for installing a wellbore (12) on a seabed (14). The apparatus includes a suction member (16) including a housing (17) defining a chamber (18). The housing (17) has an open end (20). The open end (20) defines a leading edge (22) for engagement with the seabed (14).

The conduit (28) extends from the wellhead means (24) through the chamber (18). When the wellbore (12) is installed on the seabed, the apparatus (10) provides a barrier or well barrier, which is capable of isolating and/or maintaining a wellbore pressure. The apparatus (10) allows for the installation of a wellhead (24) and/or a conduit (28) without the need of prior drilling and/or jetting operations at a wellbore site.

Abstract: A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate in near real time for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs.
