摘要： Methods and apparatus for investigating a hydrocarbon bearing geological formation traversed by a borehole are disclosed. A borehole tool is used to acquire a sample of fluid in the formation. Compositional analysis of the fluid sample is conducted to provide a determination of the composition of the sample. The sample composition is then related to a model of the thermodynamic behavior of the fluid; i.e., the mass fractions of the fluid components are used as inputs to an equation of state (EOS) to predict the phase behavior of the fluid.

摘要： A method for determining formation pressure at a depth region of formations surrounding a borehole, including: keeping track of the time since cessation of drilling at the depth region; deriving formation permeability at the depth region; causing wellbore pressure to vary periodically in time and determining, at the depth region, the periodic and non-periodic component of pressure measured in the formations; determining, using the time, the periodic component and the permeability, the formation pressure diffusivity and transmissibility and an estimate of the size of the pressure build-up zone around the wellbore at the depth region; determining, using the time, the formation pressure diffusivity and transmissibility, and the non-periodic component, the leak-off rate of the mudcake at the depth region; determining, using the leak-off rate, the pressure gradient at the depth region; and extrapolating, using the pressure gradient and the size of the build-up zone, to determine the formation pressure.

摘要： The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.

摘要： An operating mechanism (50,182) for providing mechanical advantage for mating and unmating a fixture (10) to a receiver (150) manually at a separable interface for mating complementary arrays of electrical connectors (12,152) for use in testing equipment. The leading end (80,88) of the operating mechanism (50) of the fixture is inserted into a receptacle (182) of the receiver and locks to secure the fixture to the receiver, simultaneously unlocking a subassembly (58) within the operating mechanism to be manually rotated to fully mate the now-adjacent arrays of connectors. The subassembly (58) is movably secured within an outer barrel (54) affixed to a frame (20) of the fixture and includes an axially spring biased central shaft (70) movable within an inner barrel (72). Arrays of locking balls (76,82) within apertures 86,90) of the inner barrel move between annular grooves 78,84) of the central shaft (70) and annular grooves 186,142) of a surrounding cylinder (either the receptacle 182) or the outer barrel (54)) to lock and unlock the central shaft from being axially moved with respect to the particular surrounding cylinder. An acme screw (100) within the operating mechanism converts manual rotation of a handle (52) into gradual axial movement with substantially enhanced force.
