Title: Wellbore logging
Inventor: MICKAEL MEDHAT W
IPC: G01V5/12
Filed: 1997-08-06
Abstract: A method of measuring the density of a earth formation penetrated by a wellbore includes irradiating the earth formation with gamma rays from a source 11 detecting Compton scattered gamma rays at a plurality of locations 20-28 spaced apart from the source along the wellbore, calculating a apparent density of the formation from the detected gamma counting rate at each of the locations, calcalating differences in apparent density between pairs of the apparent densities, calculating a correction for the apparent density from a distal one of the locations by scaling the differences in apparent density according to a empirical relationship, and calculating the density by combining the correction with the apparent density from the distal one of the locations. In a preferred embodiment, the empirical relationship is determined by measuring the apparent densities and differences in apparent density at a plurality of known values of density of the formation and a plurality of values of density and thickness of a medium interposed between the formation, and the source and the spaced apart locations. Scaling coefficients are determined by minimizing the value of an error function representing the difference between the known value of the density and the density determined according to the empirical relationship.

Title: Drilling and completing multilateral wells
Inventor: ALLEN DAVID WAYNE
IPC: E21B/
Filed: 1997-11-26
Abstract: The time required for establishing a multilateral well is reduced by enlarging a section of a wellbore and running a multilateral tool 7 into the enlarged wellbore section. The multilateral tool, which is suitable for running into a wellbore on a primary casing string 32, includes a preassembled combination of casing sections that are used to form dual casings strings extending from the primary casing. The multilateral tool incorporates three casing sections, which maintain the diameter of the primary casing, including: a carrier section 2, a lateral section 8, and a main section 5. In use, the tool is run with the lateral section 8 releasably held in coaxial alignment within the carrier section 2, and with the main casing section 5 fixed to the lower end of the carrier section 2. Once in place in the enlarged section of the wellbore, the lateral section 8 is released and diverted out of a preformed window 4 in the lower end of the carrier section 2 and runs generally parallel to the main casing section (Fig 2e). In this manner a lateral junction is formed at the carrier casing window 4 in which dual casing strings are connected to the primary casing 32. A second window 16, which is preformed in the upper end of the lateral section 8 is aligned with the bore of the primary casing 32 when the lateral casing section 8 is fully extended out of the carrier section window 4, thus permitting recovery of a diverting device 10 incorporated in the carrier casing section through the second window 16. The dual strings are then individually drilled and completed to target locations with pressure integrity between the dual strings maintained by using straddle equipment across the lateral junction.

Patent GB-2334478-A (GB)
Title: Workpiece support
Inventor: STARKE BERNWARD
IPC: B41F15/18
Filed: 1998-02-23
Abstract: Workpiece support comprises a plurality of pins (1) which can be advanced so that the forward ends lie in a support plane, some of the pins (1) being left retracted to form a recess in the support plane. A movable holder (4) is movable between lifting means (6) and a face plate (2) to advance the pins (1) through the face plate (2). Each pin (1) is engaged in a cartridge (3) comprising an electrical coil (9) and a permanent magnet (10). Energising the coil (9) overcomes the force of the magnet (10) to release a magnetic tappet (11) to fall into a recess in a shuffle plate (5). Diagonal movement of the shuffle plate (5) removes the tappet (11) from below the pin (1) and allows a head (1a) of the pin to pass through an aperture (13) in the shuffle plate when the holder (4) is advanced, which aperture (13) is too small to allow a tappet (11) to pass therethrough. The lifter (6) reloads the tappets (11) after the holder (4) is retracted.

Title: A borehole measuring system employing electromagnetic wave propagation
Inventor: THOMPSON LARRY W
IPC: G01V3/30
Filed: 1995-03-07
Abstract: This invention is directed toward the determination of geophysical parameters of earth formations (32, Fig 1 not shown) penetrated by a borehole (34). The invention is more particularly directed toward the determination of geophysical properties from measures of electromagnetic properties of earth formations (32) in the vicinity of a borehole either during the drilling of the borehole or subsequent to the drilling of the borehole. The downhole instrument (36) component comprises one or more transmitters 203-209 and a plurality of receivers 211,213 axially spaced along a downhole subassembly, and is preferably conveyed along the borehole by means of a drill string (37). Processor 221 controls oscillator 223 to transmit, via antennae 203, 205, a series of signals at different frequencies into the surrounding formation. These propagate through the formation to receiving antennae 211,213. Measurement and comparison with the transmitted signals provides phase shift and attenuation values which indicate resistivity and permittivity. A mathematical model can then be used to derive an indication of the nature of the surrounding rock formation and possible hydrocarbon presence. Measurements are taken up- and down-hole to eliminate system influences.
