20150285022 | MULTI-PIECE MOLDED COMPOSITE MANDREL AND METHODS OF MANUFACTURING - A mandrel for downhole isolation tools includes multiple composite pieces assembled about a common longitudinal axis at one or more common joint surfaces to font′ said mandrel, wherein each of said composite pieces is configured having a cross-sectional area less than the cross-sectional area of said mandrel, and an attachment mechanism configured to secure together said common joint surfaces. | 10-08-2015 |
20150191988 | SUBTERRANEAN BARRIER, SYSTEM AND METHOD OF USE - An orientable frac ball for substantially sealing a subterranean formation. Desired orientation can be accomplished by altering the geometry of the ball with one or more features that can be molded with or added to the ball. A projection of any shape on a ball with a length plus ball diameter that is greater than the inner diameter of the well bore will prevent the ball from orienting in an undesired position on the seat. This projection can be made of various materials that break or disintegrate when desired to remove the ball from the well bore. During the pump back process in which the balls will need to move through the progressively larger sealing seats, the projection should not hinder the removal process. It will break away or off the ball during this process. Break up features can easily be added to these tail sections. These balls can be dropped with the tail down or tail up. Alternatively, a magnet placed in the frac ball can orient the ball on a metal seat by magnetic attraction. | 07-09-2015 |
