摘要： A cement sample testing apparatus including a first pressure zone; a second pressure zone; and a pressure control system. The pressure control system can be in fluid communication with the first pressure zone and the second pressure zone, operable to raise the first pressure zone to a first pressure above ambient pressure, and operable to raise the second pressure zone to a second pressure above ambient pressure. A method for determining mechanical properties for a sample cement composition can include applying a first pressure condition to a first portion of the sample cement composition; applying a second pressure condition raised to a second portion of the sample cement composition; and determining one or more mechanical properties of the sample cement composition based at least in part on the pressure conditions present at the failure of the sample cement composition.

摘要： Producing transverse fractures in a horizontal well may be achieved at a relatively lower fracturing pressure by forming one or more tunnels extending from the horizontal wellbore. One or more tunnels may be formed at each location along the horizontal wellbore where a transverse fracture is desired. The tunnel(s) may be formed mechanically, optically, or hydraulically. Further, fracturing may be formed at a lower pressure than would otherwise be required to form transverse fractures from a horizontal wellbore. According to some implementations, the transverse fractures may be formed without isolating a portion of the horizontal wellbore.

摘要： Apparatus and method for measuring ophthalmic formulation retention on the surface of an eye include dissolving a fluorescent macromolecule in an ophthalmic formulation to form a fluorescently labelled formulation; topically administering the fluorescently labelled formulation to an eye, said fluorescently labelled formulation forming a thin film on the eye surface. Apparatus is provided for illuminating the eye to cause fluorescence of the fluorescently labelled formulation as the fluorescently labelled formulation thin film is eliminated from the eye by normal blinking and lacrimation; and for measuring fluorescence from the thin film as a function of time.

摘要： A system for providing controlled release of an active agent in an eye includes a device with a shape thereof for enabling placement of the device under a conjunctiva of an eye and additionally preventing migration of the device in the eye after placement of the device under the conjunctiva. The device may be formed of a material permeable to the passage of an agent disposed in said device. In addition, a tracer may be incorporated in the device to enable visual indication of the amount of active agent in said device when said device is disposed under the conjunctiva. To selectively treat specific areas of the eye, an impermeable layer may be provided for preventing diffusion of the active agent from a selected area of the device.
