EATON OIL TOOLS, INC.offers the Operator a choice of methods for casing exit during sidetracking operations. Both Section milling and Window milling methods are offered.

WHIPSTOCKS Use of Eaton Oil Tools' Whipstock and milling tools offers to operators new alternatives to grass roots horizontal wells. The Eaton Whipstock is a quality built tool designed to prepare or "cut a window" in the casing of your existing well bore. The Eaton Whipstock can be utilized in a vertical or high angle hole for sidetracking the original well bore or in preparation for directional or horizontal drilling. The reduction in cost per foot per recoverable barrel of oil has brought a new focus on oil in place reserves. The EATON whipstock is designed to cut a window in the casing of the existing wellbore. This design allows it to be run in vertical or high angle holes. There are two basic designs or methods for anchoring the Eaton Whipstock. The Tail Trip Design of the Eaton Whipstock may be set off a bridge-plug, junk, or any other obstruction in the well bore. Due to the design of the slip teeth, once the tail trip mechanism is set, the Eaton Whipstock can neither be lowered nor rotated. The Packer Style Eaton Whipstock is designed to tie or rotate into all styles of whipstock packers. On the first trip in the hole, both styles of the Eaton Whipstock are lowered by way of the starting mill, orientated to your predetermined direction, anchored, and initial milling of the casing window is begun. The completion of the casing window is achieved on subsequent mill runs. By utilizing Eaton's Tail Trip Whipstocks, Packer Type Whipstocks and Eaton's Carbide Mills, operators are now actively pursuing new opportunities to redefine industry standards for recovery of oil in place. With billions of barrels of oil still in formation throughout thousands of fields, the answer lies in the ability to recover a higher percentage of this oil at an equitable cost per barrel. Not only does the Eaton Whipstock provide the means to exit casing for horizontal entry into current producing zones, the Eaton Whipstock can also sidetrack well bore damage, junk in the hole, or other negative well conditions, to re-enter zones with economical reserves still in place. The benefits from a monetary position when able to bypass the cost of the vertical hole as well as the casing cost, are further enhanced by lower outlays of capitol expenditures to cut the "window " itself. The Eaton Whipstock Systems and Eaton Carbide Mills are designed such that smaller service units are capable of cutting the "window ". For the window cutting operation, tubing can be utilized since lower torque is necessary for milling. Cuttings of casing are circulated to surface at a rate as low as two barrels per minute with water as your fluid medium. With both methods, the whipstock is lowered, anchored, and milling begun with a starting mill. Subsequent mill runs will complete the casing window. Additionally, Eaton offers a retrievable tail trip style whipstock, especially designed for trouble free retrieval after completion of the directional drilling program. Using this system, allows for Multiple laterals from a single vertical hole after completion of your directional or horizontal drilling program. The Eaton Retrievable Whipstock is designed to be retrieved with a standard over shot. Should any difficulties arise in pulling the entire Whipstock, a back up feature will allow the concave to break away from the anchor mechanism. Once the concave section has been retrieved, a standard overshot can be used to retrieve the remaining section of the Whipstock.

STARTING MILLS Starting Mills are specialized milling tools used for orientation of the whipstock as well as landing and setting of the whipstock in a predetermined direction. After shearing the setting stud, the milling operation begins, guided by a tapered pilot, creating the initial cutting of the casing window.
WINDOW MILLS The Window Mill has been designed to mill the window as fast and safe as possible. The design of the mill will grind the casing like a fine metal powder instead of metal shavings or chips. With the round nose and radial ground design of the window mill, it is virtually impossible to mill up the whipstock.
WATERMELON MILLS The Watermelon Mill was made to run in tandem with other mills designed and dressed in such a way that it can mill up or down. The watermelon mill is also designed to grind up casing into a fine metal powder instead of metal shavings.
STRING MILLS The String Mill is used in the same fashion as a string reamer. It can also be used as a near bit stabilizer and is dressed with tungsten carbide to grind up casing.  Eaton Whipstocks are designed for low angle drift out of the casing, but can be designed and built with a more aggressive angle on the concave to exit casing at a higher angle to match operators needs.  With over twenty years experience in the window and milling business, Eaton Oil Tools can fulfill design and service requirements for both cased and open hole projects. Whether your AFE is designed for horizontal water flood, steam flood, water disposal, sidetracking, junk milling or enhanced oil recovery, contact Eaton Oil Tools for the tools and service to get the job done right.
EATON WHIPSTOCKS The Key Component for horizontal or high angle re-entry of existing well bores.
SECTION MILL Section mills are primarily used to mill sections in the casing for: Sidetracking, gravel packing, and/or perforation zones. Eaton's section mills are available in a variety of OD sizes, ranging from 3 1/4" to 9" O.D.'s. The blades are dressed so that all blades simultaneously mill the casing, with the milling rates usually limited by the ability of the fluids to remove the cuttings from the hole.
