Abstract: A bypass valve and method of utilizing a bypass valve located inside of a tubular or mill that allows one set of equipment to operate, operating a second tool on demand, and then providing a fluid pathway for at least a third device to operate. The bypass valve has a through bore with the restriction. Fluid flows through the restriction at a first rate that is sufficient to operate a measuring while drilling tool. The fluid flow is then increased to a second rate where the restriction causes an increase in pressure within the bypass valve. The increase in pressure allows a packer typically below the bypass valve to be set. Fluid flow is then increased to a third rate causing a further increase in pressure within the bypass valve due to the restriction.

Abstract: An anchor device is utilized to locate the whipstock both longitudinally and rotationally in order to properly orient the whipstock prior to beginning the sidetrack operation. In order to hydraulically set the slips a hydraulically actuated piston in a hydraulic cylinder is pressurized to overcome a restraint such as a shear pin thereby releasing a spring that drives a second piston to force the slips radially outwards thereby setting the anchor. In certain instances the anchor may also be set down on a rod that is also attached to the hydraulic piston. By setting down on the rod the shear pin is also overcome which also releases the spring.
