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.

Flow through treatment string for one trip multilateral treatment

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.

One trip treating tool for a resource exploration system and method of treating a formation

A swelling packer system uses modules that can be joined together and mounted over a tubular using a vertical split that can be drawn closed with a tapered pin in overlapping loops. The pins are circumferentially spaced apart as between adjacent modules. End rings can protect the modules for run in and act as extrusion barriers during and after the swelling is complete. The module ends can be overlapped in an interlocking fashion which allows multiple elements to be joined together to make a packer assembly as long as desired with any combination of swelling elements in a single packer assembly. Optionally, interior grooves in the swelling material can hold split ring seals or o-ring type seals that are slipped over a tubular end before a module is clamped on. The sealing elements can be triggered with water or hydrocarbons or with other materials already in the wellbore or introduced to it or other surface or locally actuated triggers.
