    Abstract: A system and computer program for determining the location of a seismic event in an earth formation zone using seismic traces corresponding to the event collected from one or more sensors in the zone. A graphical data window is displayed of the seismic traces corresponding to the event, the traces representing observed arrival time signals from the sensors plotted with respect to time. A window of a base map of the positions of the sensors within the zone is also displayed. Displayed in the data window is a curve plotting calculated arrival time signals for the traces, the curve being developed from a user-selected one of the observed arrival time signals displayed in the data window and from a user-selected trial location of the event selected in the base map window. The program enables user-repositioning of the trial location in the base map window such that the displayed curve moves in correspondence with the repositioning of the trial location. The trial location is repositioned until an acceptable visual coincidence of the curve is reached with the observed arrival time signals of the traces to thereby yield the location of the event. The program includes a pick-mode technique to refine the location of the event and a polarization analysis to remove ambiguity in the location of the event when more than one solution is possible.

    Abstract: Hydrocarbon fluid production wells and similar process flowstreams have a spiral baffle-type separator interposed in a surface flowline for separating fluids of different densities, such as gas from oil or gas from oil and from water, for example. Particulate solids may also be separated from the fluid flowstream. The separator (16) includes a spiral baffle (58) of single or multiple diameters interposed in an elongated cylindrical casing (72) connected at its opposite ends to suitable fittings whereby the separator may be connected to conventional fluid flowlines on the surface just downstream of a wellhead or otherwise in a process flowstream. Multiple spiral baffle separators may be connected in series to provide multiple stages for separation of fluids of different densities. The separator is particularly compact, mechanically uncomplicated and may be easily adapted to be interposed in well production fluid flowlines or conduits for process flowstreams.

    Abstract: Oil well and gas well production flow is gathered in field common line manifolds (20), (22) and conducted through a separator (34) to make a coarse separation of gas from liquid and minimize slug flow in conduits (21), (23) leading from manifolds (20), (22) to further separation, treatment and pumping facilities. A liquid level signal transmitter (52) provides a signal to a valve controller (50) which controls separate liquid and gas discharge flow control valves (48), (49) or a variable speed pump (70) to maintain a set point level of liquid in separator (34). Liquid level control is accomplished automatically by varying the flow from the fluid discharge conduit which is connected to the lower pressure flow line, which is usually the gas flow line (44). Manifold pressures may be sensed to prevent exceeding a predetermined pressure in manifolds (20), (22) and well flow lines (21), (23).

    Abstract: The particle volume and particle mass production rate of particulate solids entrained in fluid flowstreams such as formation sand or fracture proppant entrained in oil and gas production flowstreams is determined by a system (10) having a metal probe (12) interposed in a flow conduit for transmitting acoustic emissions created by particles impacting the probe to a sensor (32) and signal processing circuit (38, 40, 42, 44) which produces discrete signals related to the impact of each of the particles striking the probe. The volume or mass flow rate of particulates is determined from making an initial particle size distribution and particle energy distribution and comparing the initial energy distribution and/or the initial size distribution with values related to the impact energies of a predetermined number of recorded impacts. The comparison is also used to recalibrate the system to compensate for changes in flow velocity.

    Abstract: A gravel pack well tool (17) for use in a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone (12) and then the well tool (17) having an auger-liner assembly (20) is lowered and rotated into the preset gravel. The liner assembly (20) is comprised of a fluid-permeable liner (21) surrounded by a torque sleeve (24) which transmits torque from a workstring to a nose sub (26) at the leading edge of the liner assembly (20). The nose sub (26) has a fish-tail bit thereon to assist the downward movement of the liner assembly (20) into the preset gravel and has passages (28) therein for fluid flow therethrough in the event the assembly becomes stuck in the gravel during installation.

    Abstract: There is provided a transient electromagnetic method and apparatus for inspecting objects using moving sensor. The apparatus (13) includes a sensing portion (27) which has a transmitting antenna (29) and at least one receiving antenna thereon (31). The sensing portion (27) is located adjacent to the object which is to be inspected such that the antennas (29, 31) are adjacent to the object. The sensing portion (27) is moved along the object at the same time the transmitting antenna (29) is inducing current in the wall and the receiving antenna (31) is producing a received signal of the induced current diffusion in the wall. Because the antennas (29, 31) are moving during data acquisition, the speed of inspection is increased. The data is then interpreted to determine the thickness of the object.
