Abstract: A well treatment composition may include a capsule and a treatment agent solution within the capsule. The treatment agent solution may have a treatment agent. The system may include a radiation source: neutron, gamma, X-ray, and/or ultraviolet. A method may include introducing the well treatment composition downhole in wellbore circulation fluid, and introducing a radiation source into the wellbore and positioning the radiation source. The method may include activating the radiation source and emitting radiation that intermingles with the well treatment composition at a target location. The method may include maintaining the wellbore to allow emitted radiation from the activated radiation source to react with the well treatment composition, forming a radiation activated well treatment composition. The method may include allowing the radiation activated well treatment composition to disintegrate or dissolve, breaking encapsulation and releasing treatment agent at the target location.

Abstract: Some microcapsule forming systems include a first container containing a core material; a second container containing a shell material; one or more heaters in mechanical contact with the first and second containers; a first pair of syringe pumps operable to pump the heated core material from the first container to an encapsulation cell; a second pair of syringe pumps operable to pump the heated shell material from the first container to the encapsulation cell; a controller for controlling the one or more heaters and the first and second pair of syringe pumps; the encapsulation cell comprising a first nozzle disposed concentrically within a second nozzle, the first nozzle operable to form a sphere using the heated and pumped core material and the second nozzle operable to form a shell surrounding the sphere using the heated and pumped shell material to form a microcapsule.

Abstract: A microfluidic system (100) may include a set of replaceable microfluidic cartridges (3), each having a mechanically rigid box (202) and a set of parallel microfluidic capillaries (6), and a cooling system (216) that is in thermal contact with the mechanically rigid box (202). A gas stream may flow through the capillaries (6), and an aqueous fluid stream may flow through a space (5) in between an inner surface of the mechanically rigid box (202) and an outer surface of the set of capillaries (6). A method may include providing such a microfluidic system (100), introducing a gas stream through capillaries (6), introducing an aqueous fluid stream to flow through the space (5), generating gas bubbles (218) in the aqueous fluid stream through the capillaries (6), saturating the aqueous fluid stream with gas bubbles (218), recirculating the remaining undissolved gas through a dedicated contour tube and transferring the gas containing the aqueous fluid stream to an external storage unit.

Abstract: Microcapsule encapsulated microcapsule (MIM) material compositions and methods for preparing the same are provided for self-repairing cements that include a plurality of first microcapsules where each of the first microcapsule comprises a first core and a first shell and a plurality of second microcapsules that each comprise a second core and a second shell where the plurality of second microcapsules are dispersed within a continuous phase comprised within the first core of each of the first microcapsules. The MIM material may be prepared such that the first and second shell comprise a cross-linked material. Compositions for self-healing cement slurries are also provided and include cement, sand, water, and microcapsule encapsulated microcapsules (MIM) materials.

Abstract: A method for wellbore treatment. The method including preparing an encapsulated treatment agent via polymerization, feeding the encapsulated treatment agent into the wellbore, delivering the encapsulated treatment agent to a desired depth within a formation in the wellbore, activating an acoustic or an electromagnetic source at the desired depth within the formation, and generating an acoustic field or an electromagnetic field. The acoustic field or electromagnetic field activates the encapsulant thereby releasing the treatment agent into the wellbore and a desired depth.

Abstract: The object of the present invention is concerned with a stimuli-responsive polymer membrane and method of making the same. The method and making the membrane is a new one The entire body of the responsive membrane is a gel. Gels are used as membranes because they are permeable-swollen network. This disclosure discusses a new combination of cylindrical pores in a swollen network. When the network swells or shrinks the cylindrical pores open or close. Thus, inside the network, one can introduce ligands, function groups which due to specific interaction with some signaling molecules in the surrounding environment can cause swelling or shrinking the membrane and this way they open or close pores. With cylindrical pores in a gel there is the ability to regulate pore size in a broad range and an ability to arrange response by adding some functional groups inside the gel body.
