Casing Section Mill The "Positive Stop" system on the bottom of each section mill blade stabilizes the cutting blades for higher penetration rates. Tungsten Carbide cutting elements are formed in a "Polygon" shape and incorporate a "chip breaker" to eliminate stringers
Section Milling. Medusa® section milling and cutting technology was developed to meet the need for a cost saving, permanent and verifiable 360 degree barrier to be placed in the wellbore without the need to cut/pull and dispose of casing strings, or conduct lengthy and expensive pilot milling.
Cut, pull, and mill the 95⁄8-in. casing to gain access to the 135⁄8-in. casing for logging the annular cement. In the event that the CBL identifies a poor annular cement job in a critical area, set a 133⁄8-in. bridge plug. Section mill and underream the 133⁄8-in. casing in a similar manner to the 95⁄8-in.

Jul 18, 2019 · A Section Mill is a hydraulically actuated tool and is used to mill out a complete section of casing. Downhole section milling of casing, is generally done for the following reasons: To mill a section of casing that permits side-tracking in any direction. To mill the perforated zone in a production casing string or to expose cased off formations.
The METAL MUNCHER Turbo pilot mill is available with 18-in. blades for slot recovery and long sections of casing to be milled. The Model D™ section mill is a hydraulically operated inside section mill cutter for sidetracking and plug and abandonment operations. The knife design reduces long stringers and removes casing in short chips for easy .
To minimise potential casing wear, optimise the BHA to keep the drill pipe in tension. Reading Cuttings. Ideal cuttings are about 1/32in thick and up to 3in long. Hair-like cuttings with low penetration rates mean the weight should be increased. Fish-like cuttings when pilot milling or section milling (common when milling H-40 pipe) indicate .
The WindowMaster™ whipstock valve allows MWD equipment operation with the hydraulic WindowMaster, hydraulic PathMaster™, and hydraulic-set anchor/packers.True one-trip operation, MWD whipstock orientation, closure of flow to annulus, hydraulic packer or anchor setting, and complete milling of the casing exit greatly improve operational efficiency.
The most common method of sidetracking out of casing, especially when considerable drilling is to follow, is milling a length of casing with a section mill, then diverting the trajectory with a bent-housing motor assembly. The assembly usually contains a stabilizer on the motor and possibly another one above the motor. Steerable drilling and .

2. Consult casing string tally to establish position of casing collars and casing jewellery. • The section to be milled should start either 5 ft above or 15 ft below a casing collar to avoid the casing backing off from the coupling. • Plan to mill as few casing collars as possible and finish the milling .
The remainder of the casing is removed in a third run with the DSSM using 17-in.-long milling blades. By completely removing all casing to expose the formation, the milling run prepares wellbores for permanent rock-to-rock cement plugging. This hydraulic seal mimics natural bedding, mitigates gas migration, and can be confirmed with a pressure .
Nov 02, 2016 · In one or more embodiments, a milling tool (i.e., a casing section mill or a dual string section mill) is disclosed, which includes at least one cutting block deployed in an axial recess disposed in a tool body of the milling tool. The tool body has a central axis therethrough and is configured to couple with a tool string.
The Endura dual-string section mill passes through the restricted ID of the 9 5/8-in. casing string to the open section. Hydraulic stabilizers expand inside the 13 3/8-in. outer casing to centralize the tool. The full-gauge cut-out blades remove approximately 15 ft of casing to prepare for milling.
Various methods have been used to section mill dual casing strings with results ranging from costly multiple trips to total failures. The scope of the project was to develop a milling system that permits the removal of both 9 5/8-in. and 13 3/8-in. (or 13 5/8-in.) casing in .
