IPC: E21B21/01
Filed: 2011-06-01
Abstract: A recirculation bin, a drill tailings handling apparatus, and a method of handling drill tailings is disclosed. The recirculation bin has a moveable plate member, which advantageously may be positioned, when excess tailings are being delivered to the recirculation bin, to deflect such excess tailings into a second containment bin, for subsequent re-delivery to the recirculation bin when capacity to process such drill tailings is then available. The handling apparatus contemplates a second container, which is disposed immediately adjacent the recirculation bin, to receive deflected tailings, and is open at one end thereof to permit entry of a front-end loader therein, and thereby permit excess tailings deflected into the second container to be scooped up and delivered to the recirculation bin, when the moveable plate member is positioned to then allow the recirculation bin to accept such delivery, at a time when processing capability for such drill tailings is available.  A method for handling drill tailings is further disclosed.

Abstract: Subsurface hydrocarbon reservoir-sized structures are detected or monitored by ambient noise tomography.  Interface wave data are recorded for inter-face waves excited by seismic ambient noise. The data are recorded simultaneously at pairs of locations with the locations of each pair being spaced by less than or equal to a wavelength at the frequencies of inter-est.    The recorded data are processed (3-7) by tomography to obtain group-velocity and/or phase-velocity tomograms, which are inverted to obtain seismic parameters val-ues, such as seismic velocity. The seismic parameters may then be used to form a geo-logical model (8) of a subsurface region of interest.

Title: Use of resist coating to enhance adhesion of wheel claddings
Inventor: RANEY SHAUN
IPC: B60B3/00
Filed: 2010-07-09
Abstract: A method of securing wheel covers to the outboard surfaces of wheels to form wheel assemblies. The method involves applying resist coating patterns to portions or the entire inboard surfaces of the wheel covers prior to subjecting the wheel cover to a plating process which is intended to plate the outboard surfaces of the wheel covers. The resist coating pattern prevents plating material from attaching to areas of the inboard surfaces of the wheel covers to which the resist coat has been applied or which have been framed in or outlined by the resist coating. Areas that are coated with the resist and areas that have been framed in or outlined by the resist coating are more susceptible and compatible to adhesive bonding of the wheel covers to the wheels.
