Patent CA-2620538-A1 (CA)
Inventor: KNIGHT KENNETH G
IPC: C02F11/121
Filed: 2008-02-06
Abstract: This invention provides a Method and Apparatus for economically removing suspended solids and turbidity from used alkali metal formate brine fluids to allow such fluids to be re-used rather than disposed. This is achieved by adding a strong base to the contaminated fluid to raise the pH of the water, thereby forcing positive metal ions in the fluid to begin acting as flocculants. After flocculation of colloidal particles suspended in the fluid is complete, clarified water is decanted for re-use and the settled solids are removed.
Patent CA-2622961-A1 (CA)
Inventor: BURNSTAD ROY M
IPC: G01V1/00
Filed: 2006-09-19
Abstract: A method for reconstructing seismic data signals of poor quality to improve the signal-to-noise ratio of the data for display and analysis in connection with the selection of drilling sites for recovery of hydrocarbons. The method includes providing a signal model by applying a Karhunen-Loeve transform to selected input seismic data collected for the target zone, to form a co-variance matrix from the dot products of all pairs of input data. Eigenvalues and eigenvectors for the matrix are computed, and the most significant eigenvectors are inversely transformed to provide a coherent estimate of the signal. The input data is combined with the model data based on the determination that the model data lacks continuity, wherein the good quality signal-to-noise ratio data experiences little change and discontinuous data is enhanced by a contribution of the signal estimate data. The reconstructed seismic data of the target zone can be displayed for analysis.

Abstract: A wall anchor attachable to a wall, the wall defining a wall aperture. The wall anchor includes a body; a retention element operatively coupled to the body so as to be reversibly movable between a retracted configuration and an expanded configuration, wherein, when the retention element is in the retracted configuration, the wall anchor is insertable into and removable from the wall aperture, and, when the retention element is in the expanded configuration and the body is operationally extending through the wall aperture, the retention element cooperates with the body to attach the wall anchor to the wall; and an actuator operatively coupled to the retention element for selectively moving the retention element between the expanded and retracted configurations. Inserting the wall anchor through the wall aperture with the retention element in the retracted configuration and subsequently using the actuator to move the retention element to the expanded configuration attaches the wall anchor to the wall. Using the actuator to move the retention element from the expanded configuration to the retracted configuration with the wall anchor attached to the wall allows for the removal of the wall anchor from the wall aperture to detach the wall anchor from the wall.
