20100080260 | METHOD OF DETERMINING THERMOPHYSICAL PROPERTIES OF SOLID BODIES - The invention is related to the methods of solid bodies' thermophysical properties determination, particularly, to the methods of heat conduction and volumetric heat capacity determination. In accordance with the method heating of the reference sample and surface and sequentially located samples of the solid bodies in question is performed using a thermal energy source moving at a constant speed relative to the reference sample and samples-in-question. Excessive temperatures of the reference sample and samples-in-question at the points on the heating line are measured and by the excessive temperatures values the thermophysical properties are determined. Arbitrary shape samples are used and the samples' heat conduction and volumetric heat capacity are determined by solving the inverse-factor heat conduction problem. | 04-01-2010 |
20110078987 | CENTRIFUGAL SEPARATOR FOR SEPARATING LIQUID PARTICLES FROM A GAS FLOW - A centrifugal separator for separating liquid droplets from a gas flow can be used for scrubbing gases to be emitted into the atmosphere, as well as for separating water, oil and gas condensate droplets from a gas flow in any industry. The separator comprises a cylindrical body with axial gas flow inlet and outlet pipes and separated liquid removal sections located on the end surfaces of the body. A swirler and a central perforated pipe are installed in series and in axial alignment in the body from the gas inlet side. A conical displacer is installed in the perforated central pipe. Separation stage vanes are located between the central pipe and the conical displacer along the entire length of the displacer, and hydraulic seal vanes are placed at the same level between the central pipe and the body. The separator design provides a more efficient separation of liquid droplets from a high-velocity gas flow and can operate in any position. | 04-07-2011 |

20140020890 | Sampling Assembly For A Single Packer - A sampling assembly of a single packer assembly may have more guard drains than sampling drains. The single packer assembly having the sampling assembly may be deployed in a wellbore formed in a subterranean formation, and the single packer assembly may be deployed on a wireline cable or another deployment or conveyance. The number and the area of the sampling drains, the number and the area of the guard drains, and the positions of the sampling drains and the guard drains may be designed so that the guard drains which are operational may provide a fluid intake rate exceeding a predetermined threshold if one of the guard drains is congested and/or blocked. | 01-23-2014 |

20110155464 | METHOD FOR THE IDENTIFICATION OF THE FORMATION FLUID INVASION MOMENT - The method of the formation fluid invasion moment identification consists in the sinking of an apparatus for the sampling of the fluid mixture into the uncased wellbore; the apparatus consists of the body, standard probe, hydraulic system, sample storage chamber and pumping module. Then the fluid mixture is pumped out and simultaneously the temperature of the fluids being pumped out is measured using at least one temperature transducer positioned in the sampling apparatus hydraulic system. Based on the values obtained the graph of the derivative temperature of the pumped out fluids as function of time is built up and the formation fluid invasion moment is identified. | 06-30-2011 |
20130094624 | METHOD FOR CORE THERMAL CONDUCTIVITY DETERMINATION - A method for core sample effective thermal conductivity provides for scanning a core sample by X-ray micro-computed tomography scanner and transferring a three dimensional scan image to an image analysis computer for processing. Then a layer thickness to be analyzed is set and a layer with maximum thermal resistance is defined within the image. The value of core effective thermal conductivity is defined by the allocated layer. | 04-18-2013 |
20140056326 | METHOD FOR DETERMINING THE THERMAL CONDUCTIVITY OF AN IMPREGNATED POROUS MEDIUM - This invention relates to methods for determination of thermophysical properties of porous media filled with fluid, gas, or other mineral medium, and can be used, in particular, in the oil and gas industry. When implementing the method, it is necessary to initially determine a composition of a saturated porous medium and thermal conductivity coefficients of its components. A three-dimensional image of a sample of the porous medium is obtained by X-ray scanning. A thermal conductivity coefficient of the medium is determined by solving thermal conductivity problems, based on decomposition of a computational domain followed by composition. | 02-27-2014 |
