Abstract: An apparatus for measuring the density of a subterranean formation from within a wellbore, especially a cased wellbore. The apparatus has an energy source configured to generate 14 MeV of neutrons in pulses of 20 microseconds or less. The apparatus has at least three detectors for detecting gamma rays which are produced as a result of the neutron pulse. The detectors and energy source are aligned along a central axis with the energy source being at one end. Shielding is disposed between each of the three detectors and between the end detector and the energy source adjacent to it. The detectors are configured to measure gamma rays below 700 KeV and generate a signal in response thereto. The signals may then be compared to predetermined characteristic signals or computer simulations to determine the density, and hence porosity, of the formation.

Abstract: A method is provided for evaluating the quality of a hydraulic fracture treatment performed in a completed wellbore penetrating a subterranean hydrocarbon-bearing formation. The method is initiated by creating a pressure differential or utilizing an existing pressure differential between the wellbore and the formation and placing a lower packer and an upper packer in the wellbore. The lower and upper packers are positioned in the wellbore at or near the bottom of the producing interval to enclose one or more lower perforations within a wellbore chamber sealed to the remainder of the wellbore. Pressure values of the wellbore chamber are measured for a predetermined time period and then the lower and upper packers are repositioned to enclose the next one or more perforations in sequence within a new wellbore chamber. This procedure is repeated until pressure values have been measured in all wellbore chambers enclosing perforations of interest.

Abstract: A multi-bed, down-flow reactor includes several distributor assemblies, each having a centrally located mixing chamber and an annular collecting and mixing trough surrounding the mixing chamber. The mixing chamber has an inlet at one side thereof, an outlet in its bottom wall, and a quench gas inlet in its top wall above the outlet. A divider wall traverses the annular trough adjacent to the inlet to cause the pool of liquid collected in the trough to flow in a circular pattern around the mixing chamber to the inlet. This ensures that the liquid circulating through the trough is well mixed with the liquid raining down from the catalyst bed. Turbulent and spiraling flow patterns generated within the chamber further mix the liquid and gas and entrain quench gas in the liquid and gas stream.

Abstract: A method for removing residual oil from oily water under pressure is provided. The method comprises flowing a liquid stream of an oily water downward through a vertically extended zone to remove the residual oil. A gas is injected into the lower end of the zone and at a rate sufficient to generate bubbles of a predetermined volume in the liquid stream. A sufficient pressure is maintained in the zone to control the rate of expansion of the bubbles to a volume compatible with oil droplets in the liquid stream during upward migration of the bubbles and the oil droplets. The rate of flow of the liquid stream from the lower end of the zone and the rate of flow of the gas from the upper end of the zone are regulated to collect residual oil from a quiescent volume within the upper portion of the zone.

Abstract: A process for depth migration of seismic wave information that has been derived from geological media that causes rapid lateral velocity variations in seismic waves. The process includes the step of decomposing wavefields recorded at the earth's surface using Gaussian beams as basic functions. Then, according to the process, the set of Gaussian beams is extrapolated downward into the earth to obtain the subsurface wavefield. Finally, the wavefield is processed to provide depth-migrated images of subsurface reflectors.
