Abstract: A procedure is described for determining the power output of a downhole drilling motor, when the motor is inside the wellbore. The technique uses stand-pipe pressure and fluid flow rate as the main inputs. The power output of the motor is calculated by carrying out two low flow stall tests at flow rates lower than the drilling flow rate. These tests result in "off-bottom" and stall pressures at the two flow rates. Another off-bottom pressure is taken at the actual flow rate that will be used during drilling operations. From the use of the off-bottom and stall pressure measurements, a determination is made of the differential pressure across the motor and the stall pressure at the actual drilling fluid flow rate. A full power curve and a predicted operating stand-pipe pressure for optimal power generation are provided based on an experimentally verified assumption regarding the change in rotation rate of the motor versus the differential pressure across the motor power section.

Abstract: Apparatus for determining the density of underground formations surrounding a borehole, such as a wireline logging tool or a logging-while-drilling tool, includes a neutron source for irradiating the formations from within the borehole and at least one detector which detects neutrons and gamma rays in the borehole resulting from the irradiation of the formations with neutrons. Multiple detectors can also be used to separately detect neutrons and gamma rays. Detected neutron and gamma ray signals are each analyzed and combined to determine the density of an earth formation.

Abstract: An apparatus and method are disclosed for actively cooling instrumentation, in particular electronic circuits, in especially, high temperature environment. This apparatus has a tank containing a cooling agent, a heat exchanger to transfer heat from the instrumentation to the cooling agent, a compressor and a tank to hold cooling agent removed from the first tank. In this operation, the cooling agent tank is located in close proximity to the instrumentation. As the instruments generate heat, the heat is transferred through the heat exchanger to the cooling agent. The cooling agent boils and vaporizes from the heat and is pumped out of the tank by a compressor. As the cooling agent vaporizes and is pumped out of the tank, heat contained in the cooling agent is transferred out of the tank as well. The rate at which the vapor is pumped out of the tank controls the temperature of the cooling agent in the tank.

Abstract: The present invention provides a new method to determine corrected characteristics of materials using the measured quantities obtained by a measurement and an extensive set of database points representing laboratory and modeled results in well defined environments. In particular the invention relates to the measurement of the characteristics of the formation around a wellbore as well as of the borehole with a well logging tool. Using a dynamic parametrization technique, the environmental corrections and the transformations from the measured to the physical characteristics can be achieved in a more accurate, robust and flexible way. The dynamic local parametrization is based on a weighted multiple linear regression over the entire database to obtain the local coefficients for the transformation which can be expressed as a simple equation.

Abstract: The formation porosity of a partially invaded gas reservoir in subsurface earth formation is determined from the sum of percentages of density and neutron tool porosities. During the method of this invention, density tool and neutron tool porosity measurements are taken of the formation. These porosity measurements are fitted to a predetermined porosity to determine the percentage of each porosity measurement that will be summed to estimate the formation porosity of the gas reservoir. The percentages of the density and neutron porosity measurements are dependent on a correction factor that is determined from the fitting process.

Abstract: A multiple coring bit tool and method for taking multiple core samples of a formation traversed by a borehole in one well logging run. In this tool, multiple coring bits are used to cut the core samples. One bit is used to cut each sample. Once the core sample has been taken, the cutting bit containing the core sample is stored. For the next core, a new cutting bit is used and that cutting bit contains that core sample once the coring process is completed. Multiple cutting bits are held in two or more chambers prior to use in the coring process. The bits in one chamber are used to cut core samples from formation location above a certain hardness and the bits in the second chamber are used to cut cores in formations below a certain harness. Two other chamber are incorporated in the tool for storage of the cutting bits once the core sample has been obtained.

Abstract: The present invention provides an antenna assembly capable of operating in high temperature and pressure environments without delaminating. In this antenna assembly, the ferrites are separately impregnated with an epoxy resin under pressure and temperature and maintained at said temperature and pressure until each is cured. A low viscousity resin having a low glass transition temperature can be used to assure that the ferrites were completely impregnated with resin. The impregnated resin ferrites are then assembled into an antenna assembly and wrapped with fiberglass reinforcement. Thereafter, the entire antenna assembly is then potted under temperature and pressure to eliminate voids or air spaces, between assembly components, in order to assure a void free assembly. The fiberglass acts as a band to hold the antenna assembly together. Since the fiber has a low coefficient of expansion in the direction of the wrap, the assembly is held tightly together and is more reliable during well-logging procedures.

Abstract: A printed circuit is provided that is capable of operating at temperatures above 200.degree. C. A printed wiring board has a plating scheme of Tin plating over sulfamate nickel plated over copper. The materials are electroplated in the pattern of the desired circuit. The copper provides a conductive material for carrying electrical current. The sulfamate nickel is a ductile material that serves as a barrier between the copper and the Tin and is able to maintain its strength under temperatures of above 200.degree. C. The Tin is compatible with the new solder compound that is used to solder electrical components to the board. The solder compound is comprised of Tin and Silver. This solder has a higher initial melting point than traditional Tin/Lead solders but has a lower solder reflow temperature than conventional HMP solder compounds. This new solder is also stronger than conventional HMP solder and contains virtually no Lead component.

Abstract: This invention provides a method and system for logging an earth formation with a logging tool that is stuck (lodged) in a well bore traversing the earth formation while fishing for the stuck logging tool. This procedure is accomplished by re-establishing communication between the stuck logging tool and surface equipment during the fishing process. Communication is established by reconnecting the electrical conductors in the supporting cable after the cable has been severed in order to install fishing equipment in the well bore around the cable supporting the logging tool. The procedure to reconnect the electrical conductors requires identifying conductors in each end of the severed cable and appropriately matching conductors from each cable end to achieve electrical communication. Once there is electrical communication between the stuck logging tool and surface logging equipment, logging procedures can be continued even during the fishing for the stuck logging tool.

Abstract: A method for measuring formation density corrected for activated gamma radiation. The formation adjacent the borehole is irradiated with low energy gamma radiation from a density tool source. At least one gamma ray detection means is spaced longitudinally from the source. A gamma ray spectrum containing gamma rays that result from density source radiation and also activated gamma rays is detected by the detection means. The activated gamma rays are identified and subtracted from the total number of detected gamma rays which results in the gamma ray count from the density tool source. This gamma ray count can then be used in conventional density calculation processes to determine formation density that has been corrected for activated gamma rays caused by naturally occurring gamma radiation and from other logging equipment that induces gamma radiation.

Abstract: A method of monitoring formation fractures in real-time is performed in which a fluid containing a radio-active tracer element is pumped at a high pressure down a wellbore into a formation. As the fluid creates fractures and moves through the formation gamma-rays are emitted from the radio-active tracer element in the fluid. Detector means placed at predetermined locations in the wellbore continuously detect these gamma-rays. Gamma-rays emitted from wellbore fracture fluids are distinguished from formation gamma-rays and the detected formation gamma-rays are counted. As the fracture fluid approaches the height or vertical depth of these detecter means, the gamma-ray count increases. Once the gamma-ray count reaches a predetermined level, the fracture will have reached a desired location in the formation and pumping of the fracture fluid will stop.

Abstract: A method and apparatus for detecting natural gamma-ray signals of an earth formation and correcting these gamma-ray signals for effects from borehole gamma-rays. Gamma-ray signals are detected at two detector locations in the borehole. The borehole effects are derived from the differences between the detected signals. After the borehole effects are determined, the detected gamma-ray signal is corrected for these effects and measurements of the formation elements are derived. A differential signal between the two detectors is created by excluding a small volume of borehole fluid from one of the detectors from the borehole fluid, before detecting gamma-rays at both detectors. The excluder displaces a known volume of borehole fluid equal to the volume of the excluder. Both detectors record gamma-ray generated from the formation and borehole. The additional volume of borehole fluid at one detector causes the detected signals to be different.
