An actuator for another tool includes a housing that is either modular and attachable to the tool or may be incorporated into the another tool. Within the housing is a biasing member that may be retained in a compressed condition by a retainer. A trigger holding the retainer, the trigger having a trigger head anchorable to the housing, a separation neck having a helical groove therein and a trigger body, the body being connected to the retainer, the trigger being defeatable on command.

Actuator, method and system

A bottom hole assembly supports a diverter for landing in an existing multilateral junction. Once landed set down weight allows the BHA to progress through the diverter opening into a main bore, for example. A protective sleeve for the seal assembly lands on a shoulder above the targeted seal bore. Further advancing of the BHA moves the seal assembly out of the protective sleeve that has landed on the shoulder by the polished bore. Once the seals are in position in the bore a treatment can be accomplished. On picking up the seal assembly retracts into the protective sleeve and the BHA engages the diverter to bring the BHA and the diverter out of the borehole at the same time.

An adjustable tubular string nose uses axially relatively movable wedge segments to form a variable diameter ring shape using technology described in U.S. Pat. No. 7,128,146 in another context. The nose has a seat around a passage therethrough. After insertion of the nose into a first bore, typically a main bore, the nose is retracted out of the main bore and pressure against a seated bore in the nose expands the nose radially to a degree where re-entry into the main bore is precluded but entry into a lateral bore is still possible. The string advances onto a lateral no-go. This signals surface personnel to pick up and raise pressure to blow the seated ball through the seat to again open the passage in the nose. A seal stack behind the nose in advanced into a lateral seal bore and the treatment can then commence.

A method of treating a first bore and at least one second bore connected to the first bore in one downhole trip includes guiding a treating tool including a seal assembly defining and a shroud extending about the seal assembly downhole, guiding the seal assembly and the shroud along a diverter positioned near an intersection of the first bore and the at least one second bore into the at least one second bore, shifting the shroud relative to the seal assembly exposing the seal assembly in the at least one second bore, performing a first treatment in the at least one second bore, positioning the seal assembly and the shroud uphole of the diverter, passing the seal assembly through an opening in the diverter having a diverter opening, and performing a second treatment in the first bore.
