Abstract: A method for processing magnetotelluric data to identify subterranean deposits is provided for. The data comprise the amplitude of alternating magnetic or electrical fields recorded over time in at least two vector components at one or more locations in an area of interest. Amplitude pulses are identified in the data, wherein the pulses are time segments comprising an amplitude peak meeting defined threshold criteria in at least one vector component. The pulses are filtered at a set of predetermined frequencies to separate amplitude data at each frequency from the remainder of the amplitude data in the pulses. The frequencies correspond to subterranean depths over a range of interest. Differential impedances ?Z of the pulses at each frequency at each location are then statistically analyzed to determine a value correlated to the resistance of the earth at each frequency. The resistance values are indicative of the presence or absence of deposits at the corresponding subterranean depth at the location.

Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.

The methods comprise the steps of assembling seismic data into common geometry gathers in an offset-time domain without correcting the data for normal moveout.

The lower pass limit is also preferably set within 15% below the slowness of the primary reflection signals.

Abstract: Methods of processing seismic data to remove unwanted noise from meaningful reflection signals are provided for.

The resistance values are indicative of the presence or absence of deposits at the corresponding subterranean depth.

Abstract: An exercise machine for performing squat exercises is provided for. The exercise machine comprises a support frame with a shaft horizontally mounted on the frame for rotation about its longitudinal axis. There is at least one weight arm connected to the shaft. The weight arm is adapted to carry a weight at a point distant from the connection between the weight arm and the rotating shaft. Thus, the weight arm provides resistance and load as the shaft rotates. The novel squat machines also comprise a work arm that is connected to the shaft such that actuation of the work arm causes the shaft to rotate. A yoke is connected to the work arm. The yoke is adapted to accommodate the shoulders of an exerciser such that the exerciser is able to provide upward force on the work arm in opposition to the resistance of the weight arm by performing a squat exercise. When the exerciser performs the squat, the work arm causes the shaft to rotate and the weight arm to travel along an arcuate path.

Abstract: An exercise machine includes a frame, a removable seat, and a shaft horizontally mounted on the frame, which rotates about its longitudinal axis. Attached to the shaft is at least one weight arm and at least one work arm. The work arm can be releasably connected and take multiple forms, each adapted for particular exercises. When an exerciser pulls or pushes on the work arm, the shaft rotates and carries the weight arm in an arc from a starting or first position to a second position. Because the weight arm travels in an arc, the resistance to the exerciser varies over the course of the exercise. Further, the starting or first position of the weight arm may be adjusted to change the starting resistance to the exerciser.
