The coiled tubing-set monobore whipstock from Baker Hughes efficiently mills a window exit in your completion or production tubing, liner, or casing—without the expense of a costly workover rig.. The anchor mechanism is an integral part of this whipstock system, thus reducing the number of trips required to complete your window. The whipstock can be set with either the Baker …
For directional drillingpurposes, there were two types of whipstocks used in the old days: 1. the retrievable whipstock and 2. the permanent whipstock. The fixed whipstock stays in the hole after the desired deflection (change in hole-inclination and azimuth angles) has been accomplished, …
Typical whipstock operations through uncemented casing can require three or more round trips to prepare a window for drilling ahead. On the GB 783 A-4 BP1 well, window milling/cementing operations through uncemented casing were conducted in a single trip. The whipstock was oriented and set at 11,080 ft measured depth (MD) in a 54° angle hole.
For additional flexibility and efficiency, an openhole, flow-through whipstock can also be used with the ROk-ANkOR system. This concave provides a production through bore, eliminating the need for a whipstock retrieval trip while also providing the potential for later mechanical re-entry capability into the mainbore. Applications
The whipstock is connected to a starter mill with the shear bolt and lowered into the well on the workstring. One joined of drill pipe and a mule shoes sub if the face of the whipstock has to be oriented are placed above the starter mill and below the drill collars. If this is a blind sidetrack and the woodstock face or concave, does not have ...
Thru-Tubing Whipstock . Advantages ... The i-MILL TT intervention mill on a PowerMill TT positive displacement motor is the most effective mill for clearing cement or scale from tubing or liners to advance production or return flow to acceptable levels .
extended-window whipstock system can mill a 22.125-ft window—40% longer than a standard window—and drill a rathole to operator specifications. This significantly improves BHA pass-through, eliminating the need for additional runs to …
TrackMaster* CH with integral tri-mill achieves outstanding performance, milling a 9-5/8 inch x 13-3/8 inch uncemented window milled at ~5deg/100ft DLS in a single trip, saving ring time and cost.
Two milling methods exist to start a sidetrack from an existing wellbore. The choice of milling a section or milling a window is generally based on the degree of success that the well planners have experienced in the past with milling techniques. To quantify the process, there are some basic considerations to be taken prior to getting started.
The ProMILL* trip-saving milling and underreaming system combines a bridge plug assembly, section mill, and high-ratio underreamer in one single-trip solution, achieving rock-to-rock zonal isolation and preparing the foundation for an abandonment cement barrier.

Whipstock in drilling is a tool used to change the direction of the wellbore during drilling operations. It is a wedge-shaped device that is inserted into the wellbore, causing the drill bit to deviate from its original path.
Section milling involves milling away the complete circumference of a section of the wellbore casing or liner at a predetermined well depth. Window milling is the more economical of the two and can be completed using milling bottomhole assemblies (BHAs) in conjunction with whipstock system equipment.
