US Classification:

166387, 166187, 166206, 166382, 277333

Abstract:

The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

International Classification:

E21B 43/11

US Classification:

166297, 166 552

Abstract:

Methods and apparatus are presented for a “disappearing” perforator gun assembly. In a preferred method of perforating a well casing, inserted into the well casing is a tubing conveyed perforator having an outer tubular made from a metallic glass alloy having high strength and low impact resistance. An inner structure is positioned within the outer tubular and holds one or more explosive charges. Upon detonating the explosive charges, the outer tubular is fragmented. The inner structure is preferably also substantially destroyed upon detonation of the one or more explosive charges. For example, the inner structure can be made from a combustible material, corrodible, dissolvable, etc., material. A disintegration-enhancing material is optionally positioned between the outer tubular and the inner structure. Additional embodiments are presented having gun housings which dematerialize upon detonation of the charges.

International Classification:

B01F 13/08

US Classification:

366108, 366273, 366144

Abstract:

A system for mixing a formation fluid sample obtained in a downhole sampling chamber. The system includes a mixing element disposed in the downhole sampling chamber. A support stand is operable to receive the downhole sampling chamber. A magnetic field generator is operably associated with the downhole sampling chamber such that when the magnetic field generator generates a magnetic field, the mixing element moves through the formation fluid sample responsive to the magnetic field, thereby mixing the formation fluid sample.
