    Abstract: This disclosure provides methods, systems and devices that may be used to measure, calculate, and orient a device such as a drill bit in a downhole environment. To that end, disclosed are fiber optic gyroscopes, wherein the fiber optic gyroscopes comprise elliptical fiber optic cable coils in a mutually orthogonal arrangement that is tilted relative to a length of a supporting shaft, e.g., tube. Light travels in opposite directions within each of the elliptical fiber optic cable coils, and, subsequently, sensors detect differences in time for each light path of the light that traveled in opposite directions within each one of the elliptical fiber optic cable coils. The elliptical nature of the fiber optic cable coils minimizes the cross-sectional area of the mutually orthogonal arrangement, and thereby makes it well-suited for use in downhole environments where space is at a premium. This disclosure also may provide an inertial measurement unit.

    Abstract: In one example embodiment, disclosed is a biaxially oriented multilayer film, which may include a first tie layer and a second tie layer, wherein each has an inside surface and an outside surface. The film's core layer may consist of: (i) at least 50 wt. % high-crystalline polypropylene; (ii) both cyclic olefin copolymer and polypropylene homopolymer, or, polypropylene heterophasic copolymer; (iii) and, optionally, additives, wherein the core layer is between the inside surface of the first tie layer and the inside surface of the second tie layer. The film may also include a first skin layer on the outside surface of the first tie layer and a second skin layer on the outside surface of the second tie layer, wherein shrinkage is less than 3.5% in a transverse direction for the biaxially oriented multilayer film after subjecting the biaxially oriented multilayer film to 135° C. for 7 min at 1 atm.

    Abstract: This disclosure provides compositions and methods for a film, which may include a base film and a coating layer on the base film, wherein the coating layer has a surface energy of at least 30 dynes/cm and consists essentially of nylon, polyester, ethylene vinyl alcohol-based copolymer, polyvinyl alcohol-based polyethylene terephthalate, polyvinylchloride, acrylate-based polymers, methacrylate-based polymers, polyurethane, polyalkylimine, acid-modified polyolefins, polyetherester-amide block copolymer, and combinations thereof. Further, the film may include a metal oxide layer on the coating layer, wherein the metal oxide layer has an optical density of equal to or less than 0.5 and a thickness from 0.1 nm through 100 nm. Further still, the film has an oxygen transmission rate of less than 4 cm3/m2/day at 23° C. and 0% relative humidity, a water vapor transmission rate of less than 4 g/m2/day at 38° C. and 90% relative humidity, and a thickness of 5 μm through 50 μm.
