Weatherford's openhole whipstock system with . IPP. packer anchor is a single-trip, screw-in style whipstock with inflatable packer anchor.The inflatable injection production packer (IPP) anchor enables the operator to position the lateral departure in the openhole wellbore without a false bottom or cement barrier, accessing the pay
whipstock system selected due to: •A unique mill to whipstock connector that withstands high loads, rotates with high torque, pushes through restrictions •Faster tripping speeds with less risk of connection damage •Improved rig-floor handling since lead mill comes pre-made to connector •Robust anchor design with few moving
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.
With its cost-effective approach for exiting cased wellbores, Graco's MasterTech's compact design, short whipstock length, and compact milling assembly enable the creation of a shorter window-exit Bottom Hole Assembly (BHA). This system brings seamless navigation through the most severe doglegs. Experience a quicker kickoff and achieve a ...
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 ...
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.
The casing mill is a tool that has been solely designed for the efficient removal of downhole casing strings. The blade is manufactured from high-grade alloy steel and positions the cutting edge at the precise angle for maximum cutting and milling efficiency. Extended blade length provides maximum footage per mill.
Prepare sweeps prior to milling operations to aid clean up. Theoretical swarf weight estimation has been noted from whipstock supplier. Consider inclusion of circulation sub in the string for increased hole cleaning capability (especially if milling 7" liner – position circulation at top of liner activate and sweep at high flow rate).
Record total weight of swarf retrieved (ditch magnets, junk basket & string magnets) since start of milling and compare with theoretical milled steel weight. Sweeps should follow the Baroid …
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.

This system provides a quicker kickoff with a higher build rate in short-radius drilling applications. Decreased length of the whipstock and a milling assembly consisting of only a window mill and watermelon mill combine to form a significantly shorter window exit bottomhole assembly (BHA).
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 .

whipstock milling animation. Milling technique a critical first decision in re-entry drilling. Milling technique a critical first decision in re-entry drilling. April 1, 1997. When special sizes and debris eliminate washover options, sidetracking from a whipstock can be the most cost effective means to reach the target. During the late 1980s ...
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 ...
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 whipstock is now seven milling can begin. If the concave has to be oriented in a particular direction, the assembly is lowered to approximately twenty feet above the bridge plug. At this point, a wireline with a gyro is run in …
Single-trip 8-1/2″ whipstock-milling system was used to cut a window suitable for running drilling BHAs, liner, and completion equipment. The 9-5/8″ × 13-3/8″ annulus was monitored during milling and FIT test to check for any pressure communications. For well control scenario, arrangements were made for connecting the annulus to the ...
