| 20110181277 | METHOD OF DETERMINING FORMATION PARAMETER - A nuclear magnetic resonance relaxation dispersion method to determine the wettability and other parameters of a fluid in a porous medium such as in an earth formation is provided. The method includes the steps of measuring the spin-lattice relaxation time T | 07-28-2011 |
| 20120273273 | ANALYSIS OF DRILLING CUTTINGS FOR PERMITTIVITY - Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement. | 11-01-2012 |
| 20130329859 | Segmented Radiation Detector And Apparatus And Method For Using Same - Systems, methods, and devices involving segmented radiation detectors are provided. For example, a segmented radiation detector may include a segmented scintillator and an optical-to-electrical converter. The segmented scintillator may have several segments that convert radiation to light, at least one of which may detect radiation arriving from an azimuthal angle around an axis of the segmented scintillator. The optical-to-electrical converter may be coupled to the segmented scintillator. The optical-to-electrical converter may receive the light from the segments of the segmented scintillator and output respective electrical signals corresponding to the amount of radiation detected by each segment. | 12-12-2013 |
| 20140046628 | Method for Analyzing at Least a Cutting Emerging from a Well, and Associated Apparatus - The method comprises the following steps: —disposing at least a cutting ( | 02-13-2014 |
| 20140132258 | ASPHALTENE EVALUATION BASED ON NMR MEASUREMENTS AND TEMPERATURE / PRESSURE CYCLING - Asphaltene content and its spatial distribution in a reservoir containing crude oil is an important factor in determining the potential for formation damage and pipeline impairment, as well as planning for processing and refining of the oil. Exemplary uses include: reservoir modeling, development and depletion planning, pressure maintenance, and surface facilities management. A convenient method has been developed which uses two-dimensional NMR techniques during a temperature and/or pressure cycle to quantify the asphaltene content of the crude oil without the need for extracting the oil from the reservoir rock. The technique can be applied to core, down-hole logs, or, a combination of both. | 05-15-2014 |
| 20140184230 | MATRIX PERMITIVITY DETERMINATION (IS10.0565-US-PCT) - A method and system for determining a rock matrix dielectric permittivity. The method and system use a matching liquid with a temperature dependant permittivity. The matching liquid may be used in an automated and/or downhole system for measuring matrix dielectric permittivity of rock formations. | 07-03-2014 |
| 20140311229 | DETERMINATION OF INTERFACIAL OR SURFACE TENSION - A method and apparatus for measuring interfacial or surface tension of a first fluid dispersed in a second fluid, the method involving providing at least one substantially spherical droplet or bubble of the first fluid in a flowing stream of the second fluid in a flow channel, followed by passing the flowing stream comprising the droplet or bubble through a constriction in the flow channel, the constriction being sufficiently constricting so as to cause the droplet or bubble to deform away from its substantially spherical shape and measuring and comparing a physical property of the flowing stream both before and after the constriction, wherein the physical property changes as a result of the deformation of the droplet or bubble, and thereby inferring the interfacial or surface tension from the measured physical property. | 10-23-2014 |
| 20140338439 | METHOD AND APPARATUS FOR DETERMINING FLUID FLOW CHARACTERISTICS - A measurement device is configured in a shaped charge package to be utilized in a perforating gun section tool string. The measurement device may include for example thermal conductivity detectors (TCD) configured to measure fluid flow velocity and/or thermal characteristics of the flowing fluid. The measurement device may include for example a pair laterally spaced TCDs each having sensor faces positioned co-planar with a surface across which the fluid flows. The measurement device may include a recessed TCD, having a sensor face recessed below an opening in the exterior surface. | 11-20-2014 |
