Patent CA-2883322-A1 (CA)
Inventor: NAEDLER MARK H
IPC: E21B34/14
Filed: 2013-08-22
Abstract: An annular seat structure, for use in subterranean well stimulation operations, is operative in conjunction with associated expansion control structure to permit a predetermined number of fracture plug members to axially pass therethrough. In an illustrated embodiment thereof, the annular seat structure is movable between a retracted position having a first interior diameter, and a resiliently expanded position having a second, larger interior diameter. The seat structure has an annular array of rigid ring segments interdigitated with annular gaps that receive radially outwardly projecting portions of an annular resilient liner secured to radially inner surfaces of the rigid ring segments, the outwardly projecting liner portions being secured to circumferentially facing surfaces of the rigid ring segments. An annular spring member coaxially circumscribes the rigid ring segment array, is received in notches formed in the rigid segments, and resiliently biases the seat structure toward its retracted position.

Abstract: The invention generally relates to the field of synthetic aperture imaging. In particular, the invention relates to systems and methods for generating synthetic transmit aperture ("STA") signals and processing synthetic aperture imaging ("SAI") signals for improved signal-to-noise ratio ("SNR") and spatial resolution. This generally relates to a method to improve the signal-noise-ratio (SNR) of array signals by both encoding the transmission from multiple array elements with waveform modifications and time delays and encoding the receivers into output channels and decoding the measured signals at the selected output channels to estimate the equivalent received signals of a receiver as if only one transmitting element were fired individually in each transmission event. SAI techniques are subsequently applied to the equivalent SAI signals to obtain improved images.
