Abstract: A tubing anchor apparatus has a plurality of slips supported on an inner housing, and a first fixed cone arrangement and a second movable cone arrangement, each of circumferentially spaced cone sections, supported at opposing ends of the slips. The cone sections have working faces sloped radially and longitudinally inwardly towards the slips such that actuating the second cone sections longitudinally towards the first cone sections displaces the slips radially outward to grip the wellbore casing. The cone sections are thus double acting so that the anchor tool both stops the tool from falling down the wellbore should the deployment tubing separate and stops the tool from coming up to allow the tubing to be tensioned. The spaced apart cone sections in lobes protects the slips from catching when inserting or removing from the wellbore, while providing a high-volume annulus flow through between the circumferential spaced cone sections.

Abstract: A method of avoiding the need for a scraper run in drill out operations. The method involves the single step of incorporating a rotary scraper into the downhole drilling motor assembly in such a manner that the rotary scraper rotates with the drill bit and follows the drill bit to scrape debris from interior casing walls.

Abstract: A manifold device connects in series between the wellhead and the outer casing of a well for providing access to the outer casing of the well without removing the wellhead. The device includes a tubular body for receiving the tubing string of the well therethrough. Plural access passages are formed in the tubular body to extend generally in the longitudinal direction of the body between an external end which is spaced radially from the hollow interior of the tubular body and an internal end converging in communication with the hollow interior at the bottom end of the manifold device. Well servicing tools can be inserted into the casing annulus defined between the outer casing and the tubing string of the well through one of the access passages formed in the tubular body of the manifold device.
