摘要： An oil sample is subjected to nuclear electromagnetic irradiation downhole, and the electron and/or mass density of the oil sample is determined by measuring the attenuation of the irradiation and relating the attenuation to the electron density. If the irradiation is high energy gamma ray irradiation, the attenuation is considered to be a function of Compton scattering only, which in turn is related to the electron density of the sample. If X-rays are utilized, attenuation is preferably measured in two energy windows. Using the two different attenuation values found in the different windows, the attenuation due to Compton scattering can be found and related to the electron and/or mass density of the sample. In addition, attenuation due to photoelectric absorption may also be determined and related to the presence of one or more heavy elements in the oil (e.g., sulfur) and/or sanding.

摘要： Samples of hydrocarbon are obtained with a coring tool. An analysis of some thermal or electrical properties of the core samples may be performed downhole. The core samples may also be preserved in containers sealed and/or refrigerated prior to being brought uphole for analysis. The hydrocarbon trapped in the pore space of the core samples may be extracted from the core samples downhole. The extracted hydrocarbon may be preserved in chambers and/or analyzed downhole.

摘要： A method of retrieving a formation fluid from a formation adjacent a borehole wall includes estimating at least one of a permeability of the formation and a viscosity of the formation fluid. A first tool is selected based on the estimation, the first tool being selected from one of a heating and sampling tool, an injection and sampling tool, and a coring tool. An attempt to retrieve a formation fluid sample from the formation is then made with the first tool, and a formation fluid sample is retrieved from the formation. A second retrieval process may then be initiated, in which the second retrieval process includes increasing the mobility of the formation fluid.

摘要： The instant invention relates to a method and apparatus to determine the thermodynamic properties of a gas medium without making a determination of gas composition. In the instant invention, the pressure and speed of sound of a gas medium in a vessel are determined at multiple temperature points. According to the preferred embodiment, this information may be on a single isochore. Once the physical information is determined, an interpolation routine is executed by which initial estimated parameters such as the density and the compressibility of the gas medium will converge to accurate values. From these parameters, the thermophysical properties of the gas medium may be determined.

摘要： Electrostatic transducers (10, 100) for generating and/or sensing percussion waves have an internal rigid unitary element comprising an insulating sleeve (17, 117), an electrode backplate (21, 121) situated within the sleeve (17, 117), and a dielectric layer (22, 122) which secures the electrode backplate (21, 121) within the sleeve (17, 117). The dielectric layer (22, 122) is a generally continuous layer and has support fingers (24, 124) protruding outwardly away from the electrode backplate (21, 121) for supporting an electrode diaphragm (26, 126), preferably a durable metal foil. The electrode diaphragm (26, 126) may be hermetically sealed to a housing (111), which encloses the unitary element so that the transducers (10, 100) are better suited for harsh, extreme high/low temperature, and/or extreme high/low pressure environments. Furthermore, the interior region (32, 132) of the transducer (10, 100) can be evacuated via a throughway (31, 131) so that the transducer power can be increased.
