Abstract: Disclosed embodiments may relate to devices or tools for diverting flow within a wellbore. For example, disclosed tool embodiments may allow for more efficiently cutting and pulling of casing from a wellbore during well abandonment operations, since diverting fluid flow as disclosed may allow for a single tool string trip to allow the flow patterns for both cutting and cleanup.

Abstract: A server transmits a first page to be displayed. The first page includes a location entry representing a location to visit on a trip and at least two map elements, the two map elements and location entry being organized as a list in a first order on the first page. A request to move a selected map element of the two map elements within the list is received. Parameters of the selected map element are changed to form changed parameters that change the position of the selected map element within the list. The server transmits a second page to be displayed based on the changed parameters, the second page comprising the location entry and the two map elements organized as a second list in a second order.

Abstract: A mill assembly having a milling head which is releasable from the mill body, such as by shifting a ball clutch mechanism. The ball clutch mechanism can be shifted by dropping a pumpable plug through the work string to block fluid flow through the releasable milling head, or by increasing fluid flow through a constriction in the releasable milling head to increase the back pressure above the milling head. A check valve in the milling head can prevent uphole flow through the work string in the event of a pressure excursion. A fishing neck can be attached to the milling head.

The release mechanism can be released by dropping a pumpable plug through the work string to block fluid flow through the releasable milling head, or by increasing fluid flow through a constriction in the releasable milling head to increase the back pressure above the milling head. A check valve in the milling head can prevent uphole flow through the work string in the event of a pressure excursion. A fishing neck can be attached to the milling head.

Abstract: A liner hanger test packer assembly includes an axially translated liner top dressing mill having a calibrated shear mechanism for securing the mill at a first, top dressing position. Tool string load on the mill bearing upon the liner top in excess of the calibrated shear mechanism allows the mill to shift to a second axial position where abutment edges around the Mill base engage a tripping mechanism to drive slips against the casing wall above the liner hanger. The tripping mechanism also expands the packer seal against the casing I.D. above the liner hanger. No additional load may be imposed on the liner hanger after the anchor slips have engaged.

Abstract: A method and apparatus are disclosed which allow isolation of a plurality of zones for treatment, particularly sand fracturing. The lowermost barrier can be pumped through tubing and anchored in cased or open holes. In the preferred embodiment, the pumped plug has a visco-elastic member which contains a particulate aggregate mixture, such as described in U.S. Pat. No. 5,417,285. The visco-elastic material is subjected to a force which changes its shape so that the material obstructs the wellbore. The shape change also accomplishes dehydration of the material within the visco-elastic enclosure by virtue of fluid displacement, resulting from a volume reduction, hardening it so that a plug using the visco-elastic material is formed. Thereafter, a packer on the tubing string is set to isolate the zone for sand fracturing. The process can be repeated without tripping out of the hole as additional plugs are pumped through tubing and the process is repeated.
