摘要： The side tracking system includes a window mill having a full diameter cutting surface and a reduced diameter tapered cutting surface and a whipstock having a ramp engaging the reduced diameter cutting surface. The cutting tool has a body with diamond cutters initiating cutting of a steel casing, milling a window through the steel casing and drilling a secondary borehole. The materials of the whipstock have a first cutability and the materials of the casing have a second cutability. The reduced diameter cutting surface contacts the whipstock ramp at a first contact area and the full diameter cutting surface contacts the wall of the casing at a second contact area. As weight is applied to the mill, there is a first contact stress at the first contact area and a second contact stress at the second contact area. A cutability ratio is the first cutability divided by the second cutability and a contact stress ratio is the first contact stress divided by the second contact stress. The mill cuts the casing rather than the whipstock by maintaining the product of the cutability ratio and the contact stress ratio less than one.

摘要： The retrieval tool includes a cylindrical member having a body, an inner passage, a guide cylinder and an engaging member. The engaging member may slide within the cylindrical member in order to frictionally engage a whipstock against an inner surface of the guide cylinder, facilitating removal of the whipstock from a borehole. A actuating member, piston, retainer and swivel sub may be used to connect the engaging member to the retrieval tool and enhance the mobility of the engaging member within the cylindrical member. A spring may also facilitate locking engagement of the engaging member and whipstock. Contact between the retrieval tool and the whipstock may lead to an increase of pressure within the inner passage, such pressure increasing the engagement between the engaging member and whipstock.
