  • Patent number: 4203161
    Abstract: A method of enhancing a "gather" formed of a plurality of unmoved out common depth point (CDP) data traces. The gather is formed of a plurality of seismic traces arranged in a display in which time varies along the horizontal axis and distance between source and detector (range) varies along the vertical axis. The gather is incrementally processed by cross correlating trace segments within a defined area or search window. To this end, the center trace within the window is selected as a reference trace which is multiplied by a taper function and cross correlated with the other traces in the window to provide a coherent trace and a separate noise trace, both of which are produced in the output. The window is shifted on the gather and the procedure is repeated until every trace has been processed. In the cross correlation technique, the trace segments in the window are examined along a derived hyperbolic curve.

  • Patent number: 4199953
    Abstract: A radiation detector assembly is enclosed in a heat pipe which is positioned in a dewar flask. A thermo-electric cooler is joined to one end of the heat pipe. The heat exhaust of the thermo-electric cooler is communicated to a heat dissipation device in the form of a fin assembly. A thermistor senses the temperature at the heat pipe. When the thermistor indicates a temperature in excess of that corresponding to a reference signal, a control singal is produced by a control device to cause a power source to operate the thermo-electric cooler to remove heat from the heat pipe to the fin assembly. The vacuum within the dewar flask effectively limits the environmental heat passing to the heat pipe to radiant heat. The detector assembly and temperature stabilization system may extend to the interior of a conduit or other housing containing material whose radiation is to be detected, while the fin assembly is exposed to the atmosphere.

  • Patent number: 4200154
    Abstract: The production of hydrocarbons from a subterranean hydrocarbon-bearing formation containing acid-soluble components, such as one containing clays or siliceous minerals as exemplified by sandstone, shale, etc. is stimulated by injecting into the formation a composition comprising an aqueous solution of a mineral acid and a fluorine-containing acid or salt and having dissolved therein an oxyalkylated acrylamido alkanesulfonic acid polymer. The indepth increase in the permeability and porosity of the formation achieved utilizing the method of invention results in a substantial improvement in hydrocarbon recovery.

  • Patent number: 4200789
    Abstract: In a pipeline or container at any of various petroleum producing operations, a multiphase fluid flowstream containing oil, water and gas is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the ratio of the gamma ray counts of the element sulfur to the element chlorine. From this ratio, the oil and water cuts of the fluid may be measured while eliminating the effects of gas in the flowstream on the measurements.

  • Patent number: 4200411
    Abstract: Underwater liquid storage tank or facility adapted to hold or temporarily store varying quantities of a liquid having a density less than water. Said liquid can include crude oil and petroleum products. The facility includes means for maintaining the holding space in a full condition by the addition or removal of water. Further included is means to avoid inadvertent pollution of the surrounding water through the unintentional discharge of amounts of the less dense liquid which can be carried by water leaving the tank. Also included is means forming a protective barrier about the liquid holding tank to avoid serious leakage and possible damage to the environment in the event the facility is ruptured by a floating vessel or other object.

  • Patent number: 4200151
    Abstract: Significant improvement in the recovery of hydrocarbons from a subterranean hydrocarbon-bearing calcareous formation is accomplished by injecting into the formation via an injection well drilled into a formation communicating with an adjacent producing well and containing acid-soluble components which may or may not have water-sensitive clays and shales included therein, an acidic aqueous oxyalkylated acrylamido alkanesulfonic acid polymer solution whereupon the acid solution reacts with the acid-soluble components of the formation creating passageways or enlarging existing passageways thus facilitating the flow of fluids therein and thereby increasing the recovery of hydrocarbons from the formation through the adjacent producing well.

  • Patent number: 4191884
    Abstract: Gamma ray spectra of earth formations surrounding a well borehole are obtained by bombarding the formations with neutrons from a pulsed neutron source and detecting the gamma rays resulting from capture of thermalized neutrons in the formation using a germanium gamma ray detector. A measure of the ratio of chlorine to hydrogen is obtained from the detected gamma radiation spectra, and the apparent formation water salinity is determined from the chlorine/hydrogen ratio. The water saturation of the formation is then obtained from the apparent formation water salinity and the true formation water salinity. Compensation is made for the presence of saline water in the borehole fluid and in the cement annulus, as well as for any bound water in the formation.

  • Patent number: 4189638
    Abstract: Water injection profiling of a well by nuclear logging is disclosed. A dual detector sonde with a high energy neutron source is oriented and positioned above and below perforations in the casing of an injection well to monitor upward and downward flow, respectively, of injection water. The water is irradiated by the neutron source and resulting gamma ray production is sensed as the activated water flows by the spaced detectors. Count rate data is reduced and analyzed in terms of two energy windows to obtain linear flow velocities for water flow within and behind the casing. Volume flow rates are determined for upward and downward flow, and horizontal volume flow into the surrounding formations is calculated.
