20150152702 | Lower Mill Spaced Cutting Ring Structure - The cutting structure on the lower mill is arrayed in rows that are preferably parallel. The cutting structure in each row is made sharper and more durable than prior designs with the objective of cutting the window higher than where the window mill started the window. The use of the rows increases the contact stress of the inserts on the casing inside wall because at any given time fewer and sharper inserts are cutting the casing wall to lengthen the window. As a row wears down the next row takes over to continue the cutting where the previous row was active and to further penetrate the casing wall. The cutout angle can also increase as this occurs. As a result a decreased insert density results in more effective casing wall cutting to extend the window to allow larger tools to exit into the window off the whipstock. | 2015-06-04 |

20150152707 | Compliant Seal for Irregular Casing - A setting assembly for a packer seal features a series of peripherally mounted rod pistons that abut the seal to be set by advancing the seal relative to a tapered surface. When parts of the seal engage an inner tubular wall before other parts of the seal the continuation of application of hydraulic pressure to the pistons moves parts of the seal that have yet to make contact with the tubular wall further relative to the ramp so that plastic deformation of the seal assembly can occur to allow portions thereof to move radially further outwardly to seal in the region where the radius of the tubular is enlarged. When hydraulic pressure is applied to the pistons in an opposite direction a lock mechanism is defeated and the c-ring or scroll reverts to a smaller shape optionally aided by a garter spring so that the packer can be selectively retrieved. | 2015-06-04 |
20150152708 | Laser Plug and Abandon Method - A well is abandoned by locating a plug in casing preferably at a location above where the quality of the cement job or the casing is questionable. A high powered laser is run in preferably on wireline and at a location above the plug is activated and rotated with the effect that the casing, cement behind the casing and the formation about the cement becomes molten and flows onto the plug where the mass cools and solidifies into a cohesive mass that spans the borehole and extends laterally into the formation. The mass is impervious and the abandonment procedure is complete. The plug can be bare or it can have layers above such as cement to protect the plug from molten temperatures until the mass cools sufficiently and solidifies. | 2015-06-04 |

A burst band disposed outside the housing at the port can break away from the housing in response to a particular pressure level communicated through the open port. In particular, the insert can have a seat that engages a deployed plug or ball. The insert shifts open when a first level of applied pressure against the seated ball shears the insert free. This can give a first indication that the insert has moved open. Then, a second level of pressure can be detected when the burst band breaks as a second indication that the insert is opened. | 2015-06-04 |
