at least one bearing around the shaft, the at least one bearing including a journal bearing having an inner sleeve and an outer sleeve, a radial clearance between an outer diameter of the inner sleeve and an inner diameter of the outer sleeve being between 1 ?m and 1 mm;
an impeller around the shaft and the at least one bearing, the impeller including a magnetized portion;
a spring axially between the at least one bearing and the housing, the spring being configured to compress when a fluid applies an axial compressive force to the impeller; and
a sensor configured to sense a rate of rotation of the impeller, measure the axial compressive force on the impeller, or both;
pumping the fluid into the wellbore, the fluid causing the impeller to rotate, at least a portion of the fluid flowing through the radial clearance between the inner sleeve and the outer sleeve; and
determining at least one property of the fluid using the electronics assembly and data related to the rotation of the impeller.

SWIVEL PRESSURE HEAD AND METHOD OF USE

1. A swivel pressure head comprising:an upper housing including a top surface, a bottom surface, an interconnecting side surface, and an internal bore formed by an internal bore wall, the internal bore extending from a fluid inlet to an opening on the bottom surface of the upper housing;
a lower housing including a top surface, a bottom surface, and an interconnecting side surface, the lower housing having a central bore extending from the top surface to the bottom surface, the central bore formed by a central bore wall, the central bore including a reduced diameter upper section and an enlarged diameter lower section;
a fixation mechanism detachably securing the bottom surface of the upper housing to the top surface of the lower housing whereby the internal bore of the upper housing is in communication with the central bore of the lower housing;
a pressure sleeve having an outer cylindrical surface and an internal bore extending from an upper fluid inlet to a bottom fluid outlet, the pressure sleeve including an enlarged outer-diameter bottom section and a reduced-outer diameter extension section, the enlarged outer-diameter bottom section including a top shoulder surface and a bottom surface;
a locking nut operatively engaging the pressure sleeve and configured to operatively engage a swivel stem so that rotation of the swivel stem rotates the pressure sleeve, the locking nut containing an internal bore having an upper portion dimensioned to accommodate the reduced outer-diameter extension section of the pressure sleeve and a lower portion dimensioned to accommodate the enlarged outer-diameter bottom section of the pressure sleeve, the locking nut being positioned within the enlarged diameter lower section of the central bore of the lower housing, the reduced outer-diameter extension section of the pressure sleeve extending upward through the reduced diameter upper section of the central bore of the lower housing and into the internal bore of the upper housing; and
a packing assembly positioned in the internal bore of the upper housing, the packing assembly providing a fluid seal between the internal bore wall of the upper housing and the outer cylindrical surface of the pressure sleeve to define a fluid path from the fluid inlet of the upper housing, through the internal bore of the upper housing, and through the upper fluid inlet and internal bore of the pressure sleeve.

SHAKER SCREEN ASSEMBLY

1. An apparatus comprisinga screen frame having a screening surface provided by an array of openings separated by transverse ribs; and
a scalping surface having a plurality of openings formed therethrough;
a vertical base portion contacting the screen surface of the screen frame such that the vertical base portion connects the scalping surface to the screen frame; and
a scalping surface support member disposed vertically between the scalping surface and the vertical base portion such that the scalping surface support member spaces the scalping surface a vertical height above the screening surface of the screen frame.

AUTOMATED PIPE TRIPPING APPARATUS AND METHODS

Ensco Services Limited, ...

1. A method, comprising:lifting a string at a relatively constant speed defining a tripping speed;
moving an inner frame downward with respect to an outer frame to a first location;
moving an iron roughneck relative to the inner frame into an upper position inside of the inner frame as the inner frame is moving downward with respect to the outer frame;
moving the inner frame upwards relative to the outer frame at the tripping speed to align the iron roughneck with a threaded joint of the string; and
breaking out the threaded joint with the iron roughneck.
