Abstract: A ball release mechanism is mounted near the intended seat. The ball or balls are kept out of the circulating stream. High circulation rates followed by curtailment of circulation places an outlet port in position to allow the ball or balls to be pushed out by a spring. The spring or one of the balls prevents the return of an ejected ball back into the protected pocket. The ball is delivered to the seat without circulation.
Abstract translation: 球释放机构安装在预期座位附近。 球或球保持在循环流中。 高循环率随之而来的流通量减少了出口口，使球或球被弹簧推出。 弹簧或其中一个球防止弹出的球返回受保护的口袋。 球被送到座位而不循环。

Abstract: A downhole vibration tool consisting of a body assembly installed in a work string, and a drop-in dart valve assembly. An open inner bore through the body assembly allows the performance of operations through the body assembly. To activate the vibration tool, the dart valve assembly is dropped into the work string and pumped downhole into engagement with the body assembly. Once the dart valve assembly is in place in the body assembly, continued pumping of fluid will cause the tool to begin to vibrate longitudinally. When the jarring operation is finished, the dart valve assembly can be released from the body assembly and retrieved, with a wireline or coiled tubing unit.

Abstract: A tool for cutting or milling casing in a well is disclosed. It includes a plurality of blades extending outwardly to a substantially radial position for cutting the walls of casing strings and removing a predetermined length of the casing strings in a cutting action. The blades have cutting elements positioned on leading faces of the blades to engage the casing strings in a cutting action without tripping or removal from the bore hole. The cutting elements can be arranged in rows and columns. The cutting elements can be shaped to continually present a sharp cutting edge to the object being milled. The cutting elements can be inclined at a negative axial rake angle to cause the metal chips cut from the object being milled to break off at short lengths. The cutting element can also have surface irregularities to cause the metal chips cut from the casings to break off at short lengths. The cutting element can also have stress relieving grooves to prevent the propagation of a crack across the face of the element.
Abstract translation: 公开了一种用于在井中切割或铣削套管的工具。 它包括多个叶片，其向外延伸到基本上径向的位置，用于切割套管柱的壁并在切割动作中移除预定长度的套管柱。 叶片具有定位在叶片的前表面上的切割元件，以切割动作使套管柱接合，而不会从钻孔中脱落或移除。 切割元件可以排列成行和列。 切割元件可以被成形为连续地向被研磨的物体呈现锋利的切割边缘。 切割元件可以以负轴向前角倾斜以使得从被研磨的物体切割的金属屑以短的长度断裂。 切割元件还可以具有表面不规则性，以使得从壳体切割的金属屑以短长度断开。 切割元件还可以具有减轻应力的凹槽，以防止裂纹在元件的表面上传播。

Abstract: This invention relates to a permanent whipstock assembly which uses camming pivot arms to secure the whipstock at the desired location within a cased wellbore. Camming pivot arms are pivotally attached to the downhole end of a whipstock housing and are further attached to a slip pad. Intentionally induced relative movement of the slip pad and the whipstock housing causes the camming pivot arms to pivot in such a manner that slip pad housing 4 and slip pad 5 are forced away from each other and cammed into the cased borehole. The invention relates specifically to a device that is particularly adapted to be lowered through a small diameter and later to be activated and set in a much larger casing or hole diameter.

Abstract: A cutting tool (10) for removing members downhole from a well bore and adapted to be inserted within a well from the upper end (12) of the casing (14). The cutting tool (10) includes a plurality of elongate blades (32) on the cylindrical body (18) of the cutting tool (10). Cutting elements (42) of a predetermined size and shape are arranged in a symmetrical predetermined pattern on each blade (32) in side-by-side relation in a plurality of predetermined transversely extending rows and a plurality of predetermined generally vertically extending columns. The cutting elements (42) in adjacent transverse rows for each blade (32) are staggered and have different concentric cutting paths. The cutting elements (42E) in corresponding transverse rows on adjacent blades (32A, 32B) are staggered and have different concentric cutting paths. The blades (32A, 32B) of the embodiment of FIGS. 7-13 have a separate recess (50) on the leading face (34A) for each individual cutting element (42E) for precisely positioning the cutting element (42E). Each cutting element (42E) has a groove (42K) for receiving and directing forwardly the extending end of a metal shaving (S) to facilitate breaking thereof from the casing (14).

Abstract: A debris removal tool has a lower end pickup hose into which debris laden fluid is pulled when there is circulation through the debris removal tool from the surface. An anchor near the open end of the hose stabilizes the lower end near a recess or groove from which debris is to be removed. Once the anchor is set the hose can be extended or retracted as well as rotated on its axis to pick up debris. A camera can be located in or near the hose opening to be able to see where the debris is located and for confirmation that the debris is being removed and that the debris has fully been removed.

Abstract: A debris removal device features structural support from an exterior housing that allows more space for debris collection. The debris enters the collection volume from the top to eliminate debris from having to go through a valve. The screen in the device is disposed internally to protect it during handling and running. A variety of external flow diverters are used to direct debris laden fluid into the tool and to keep debris out of an annular space around the tool that could interfere with its removal. The diverters can be actuated by relative movement in the tool or applied pressure to a piston which can inflate a sleeve or orient or misalign paths through brushes for selective bypassing of fluid exterior to the tool.
