WO/2015/178899 METHOD AND SYSTEM FOR ENHANCING NATURAL GAS PRODUCTION||WO||26.11.2015|
||PCT/US2014/038893||SHELL OIL COMPANY ||SEEBERGER, Friedrich Christoph |
A Nitrogen Assisted Depletion Drive (NADD) for enhancing natural gas recovery from a natural gas containing formation (20,30) comprises injecting into the formation a corrosive CO2 containing drive gas after initially injecting a non-corrosive Nitrogen(N2) containing drive gas, which has at an ambient pressure of 1 bar a volume of at least 100 million m3 to provide in the formation a barrier that inhibits mixing of the corrosive drive gas with the natural gas and inhibits the corrosive drive gas to reach natural gas production wells and other corrosion prone natural gas production facilities.
WO/2015/178886 METHOD OF STIMULATION OF BRITTLE ROCK USING A RAPID PRESSURE DROP||WO||26.11.2015|
||PCT/US2014/038642||HALLIBURTON ENERGY SERVICES, INC. ||MARTYSEVICH, Vladimir, Nikolayevich |
A method and system for inducing secondary orthogonal fractures in an underground formation by introducing a proppant carrying fluid into a hydraulic fracture in an underground formation at high pressure is provided. The pressure of the proppant carrying fluid is lowered at a rate allowing the fluid to exit the formation while the proppant remains in place within the fractures. The pressure of the fluid is then rapidly reduced, creating fractures orthogonal to the surface of existing fractures by pushing remained proppant against hydraulic fractures walls. The orthogonal fractures can be opened with high pressure fluid and propped. In this way, the portion of the formation in fluid flow communication with the wellbore is increased.

WO/2015/178889 CREATING A CHORDING KEYBOARD MAPPING TABLE METHOD||WO||26.11.2015|
||PCT/US2014/038648||SKOGSRUD, Simen Svale ||SKOGSRUD, Simen Svale |
A method of creating a chording keyboard mapping table is described. An exercise is created that is performed by users of a keyboard for which a mapping table is desired. The psychomotor performance of the users transitions between chords is recorded―as distinct from performance relating to chords. A first trial keyboard mapping table (from chords to symbols) is created, and the effectiveness of that table is measured by applying it to a text corpus and measuring the total psychomotor cost to enter that corpus with that table. The table is then permuted, and the cost recomputed. Trial tables are repeatedly permuted, with one or more preferred tables being used as the basis for the next iteration of permutations. This continues until a terminating event, such as minimal improvement, is reached. Variations as embodiments are described. Software to implement the method is claimed
WO/2015/178876 A MAGNETIC INDUCTION SENSOR WITH AN ELECTRO-OPTICAL TRANSDUCER AND RELATED METHODS AND SYSTEMS||WO||26.11.2015|
||PCT/US2014/038542||HALLIBURTON ENERGY SERVICES, INC. ||WILSON, Glenn, A. |
Electromagnetic (EM) measurement systems and methods for a downhole environment are described herein. An example system includes an optical fiber, an EM source to emit an EM field, and a magnetic induction sensor. The magnetic induction sensor comprises a coil and an electro-optical transducer coupled to the coil and the optical fiber. The electro-optical transducer generates a light beam or modulates a source light beam in the optical fiber in accordance with a voltage induced in the coil by the EM field. An example method includes positioning an optical fiber and magnetic induction sensor in the downhole environment, the magnetic induction sensor having a coil and an electro-optical transducer coupled to the coil and the optical fiber. The method also includes emitting an EM field and generating a light beam or modulating a source light beam, by the electro-optical transducer, in the optical fiber in accordance with a voltage induced in the coil by the EM field.
WO/2015/178882 RESEALABLE FLEXIBLE PACKAGES||WO||26.11.2015|
||PCT/US2014/038605||BEMIS COMPANY, INC. ||TRACY, Jordan, R. |
A resealable flexible package is provided comprising polymeric wali panels and a peel- reseal feature sealed therebetween. A peel-off portion is removed to transition the package from a closed position to an open position, removal of the peel-off portion both opening the package and exposing a pressure sensitive adhesive of the peel-reseal feature. The exposed pressure sensitive adhesive is coupled to one of the wail panels and moved into adhesive engagement with an exterior surface of another wall panel to transition the package to a reseated position.
WO/2015/178881 STANDING INJECTION VALVE WITH HYDRAULICALLY DAMPENED VALVE CLOSURE||WO||26.11.2015|
||PCT/US2014/038595||HALLIBURTON ENERGY SERVICES, INC. ||WILLIAMSON, JR., Jimmie Robert |
An injection valve assembly for use in a well, where pressurized gas or fluid from uphole in the well displaces a perforated valve head from a valve seat, allows for fluid flow of the pressurized gas or fluid into the valve head and further downhole in the well toward an electric submersible pump. A compression spring is coiled around a valve stem connected to the valve head, pushing the valve stem and valve head in an uphole direction opposite to the force from pressurized gas or fluid. The compression spring is in a chamber filled with hydraulic fluid, where the hydraulic fluid can pass through a dampening system assembly and a flow restrictor assembly, thereby regulating the speed at which the valve stem and valve head can move relative to the valve seat.
WO/2015/178938 FLEXIBLE LAYERED EYEGLASSES||WO||26.11.2015|
||PCT/US2014/039521||BLOCKHOUSES, INC. ||BLOCK, Jonathan, David |
Disclosed are various embodiments for an eyeglass band comprising a plurality of layers, wherein at least one of the layers comprises a bistable or multistable band and at least one layer comprises a lens. The eyeglass band, via the spring band, may be elongated in a first fixed position when tension within the springy metal bands is created. When the tension within the springy metal bands is lost, the flexible bistable spring band will cause the bistable eyeglass apparatus to change to either a second position or a third position. The lens may be in an eyelevel position when the eyeglass band is worn on a face of a wearer.
WO/2015/178894 SLANT LENS INTERLACING WITH LINEARLY ARRANGED LENSES||WO||26.11.2015|
||PCT/US2014/038828||LUMENCO, LLC ||RAYMOND, Mark, A. |
An optical product that includes a transparent lens sheet, which has a first side with a plurality of side-by-side sets of linearly arranged lenses. Each of the sets of lenses is at a slant angle in the range of 10 to 46 degrees from a vertical or a horizontal axis of the lens sheet. The product includes an image layer that includes pixels from a number of digital images. The pixels are arranged in a pattern of pixel locations providing non-orthogonal interlacing of the digital images relative to each of the sets of the linearly arranged lenses. The pattern of pixel locations aligns a number of the pixels from each of the digital images to be parallel to a line extending through a center of the linearly arranged lenses in each set. Each of the linearly arranged lenses may have a round base, a hexagonal base, or a square base.
