Additional properties of the earth formation are predicted using the pore-scale model. The additional properties may be based on additional measurements of properties ... 07/20/06 - 20060161352 - Estimating formation properties from downhole data Methods and systems for extracting formation properties from formation logging data is disclosed. A method includes obtaining a deconvolution filter; and processing the formation logging data using the deconvolution filter to produce estimates of the formation properties. The estimates of the formation properties may be further processed with a diffusion ... 06/08/06 - 20060122779 - Interpretation methods for nmr diffusion-t2 maps A method is disclosed for interpretation of multi-dimensional nuclear magnetic resonance data taken on a sample of an earth formation. Specifically, a set of NMR data is acquired for a fluid sample located either in a borehole or in a laboratory environment. From the set of NMR data, a multi-dimensional ... 03/09/06 - 20060052938 - Method for creating facies probability cubes based upon geologic interpretation A method for creating a facies probability cube is disclosed. A S-grid containing facies is first created. The grid includes layers of cells and columns of cells. Vertical facies proportion data for the layers of cells is derived from sources such as well data, conceptual vertical geologic sections and graphs ... 01/26/06 - 20060020390 - Method and system for determining change in geologic formations being drilled The present invention provides a method and system for determining change in geologic formations being drilled. In accordance with one embodiment of the present invention, a method for determining change in geologic formations includes receiving a plurality of values of formation change indicators. For at least one formation change indicator, ... 01/19/06 - 20060015258 - Method and device for determining the resistivity in a geological formation crossed by a cased well The invention concerns a method for determining the resistivity in a formation crossed by a cased well, in which one carries out at least one resistivity log in the cased well and one uses the results of at least one resistivity log in the non-cased well, carried out in the ... 09/01/05 - 20050192753 - Method of determining planar events from borehole or core images The present invention relates to a user-guided dip picking method from electrical borehole images using Hough Transform. It includes defining a top and bottom reference curve, applying the Hough Transform to the borehole image limited by the top and bottom reference dips so that the Hough Transform space is restrained ... 08/25/05 - 20050187715 - Method for measuring formation properties with a time-limited formation test An apparatus and method for determining at least one downhole formation property is disclosed. The apparatus includes a probe and a pretest piston positionable in fluid communication with the formation, and a series of flowlines pressure gauges, and valves configured to selectively draw into the apparatus for measurement of one ... 08/18/05 - 20050182566 - Method and apparatus for determining filtrate contamination from density measurements The present invention provides a downhole method and apparatus to determine the percentage of oil based mud or water based mud filtrate contamination in a formation fluid sample. The present invention determines the percentage of filtrate contamination in a sample comprised of a mixture of crude oil and an oil ... 08/04/05 - 20050171699 - Method for determining pressure of earth formations 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, ... 07/28/05 - 20050165554 - Fluids chain-of-custody A method of assuring the collection of reliable and quality fluid sample includes the steps of acquiring a fluid sample at a point of acquisition, analyzing physical and chemical properties of the fluid sample at the point of acquisition; recording the point of acquisition sample properties in an electronic database ... 07/28/05 - 20050165553 - Method for evaluating formation properties Methods for evaluating the properties of formations surrounding a borehole, include the steps of measuring electrical properties of the formation from within the borehole; deriving a model of parameters of the formation surrounding the borehole; and estimating the properties of the formation using the model to interpret the measured electrical ... ### FreshPatents.com Support |
