20130345367 | METHODS FOR PREPARATION OF NOVEL GRAFT COPOLYMERS - The present invention relates to novel graft copolymers of functionalized poly(isoolefin-co-conjugated diolefin, and a process of preparing such graft copolymers. The present invention also relates to a method of preparing functionalized copolymers of isoolefins and conjugated diolefins. | 12-26-2013 |
20140045986 | BUTYL IONOMER LATEX - The invention relates to a latex composition wherein the latex composition comprises a butyl ionomer or partially halogenated butyl rubber ionomer. The latex composition is formed by dissolving the butyl ionomer in a suitable solvent, emulsifying the polymer in the solvent, adding water and optionally a minor amount of a suitable surfactant system to the emulsion and concentrating the emulsion to remove the water. The advantages of butyl ionomer latex include lower emulsifier levels, increased latex stability, improved interaction and adhesion to polar substrates and surfaces. Through the judicious choice of emulsifiers and/or washing to remove excess emulsifier a film with enhanced non-extractable polymeric antimicrobial function can be created. These properties of ionomer latex are useful in coatings, dipped goods and sponge applications. | 02-13-2014 |

20140238693 | WELLHEAD SYSTEM FOR TIEBACK RETRIEVAL - A wellhead assembly includes a casing head, tubing head, and a production tree mounted on the tubing head. An isolation sleeve is set in a main bore of the wellhead assembly that extends across an interface between the casing and tubing heads so that a portion resides in each. The isolation sleeve is configured so that a fracturing string, and its associated hanger, can be retrieved through the isolation sleeve; which significantly reduces the time and steps required to conduct a fracturing operation in a well. Moreover, the present isolation sleeve can be used without changes to existing casing or tubing heads. | 08-28-2014 |

20140116723 | METHOD OF INSTALLING A MULTI-BOWL WELLHEAD ASSEMBLY - A method of completing a well includes Lowering a wellhead onto a base al as upper end of the well. A hub with internal threads and an external circumferential stepped recess is secured to external threads of the wellhead. A blowout preventer assembly with an annular locking member having a plurality of locking demerits is landed on the hub, and the looking elements are engaged with the recess of the hub. The well is drilled through the blowout preventer assembly to a greater depth then the blowout preventer assembly and the hub are removed. A threaded flange with & plurality of bolt holes spaced around die flange is secured to the external threads of the wellhead and a wellhead member is bolted to the bolt holes of the threaded flange. | 05-01-2014 |
