Abstract:
A multilayered film for performing spectroscopic measurements in a fluid are provided. The multilayered film includes a substrate; a porous layer adjacent to the substrate; and a reflective layer formed on the porous layer, wherein the porous layer selectively allows a component of a fluid to be optically measured when the multilayered film is immersed in the fluid. A sensor for spectroscopic measurements in crude oil samples including a multilayered film as above is also provided. A method of manufacturing a multilayered film for spectroscopic measurements in fluids as above is also provided.
Abstract:
The disclosure relates to logging sensor or tool including an electromagnetic radiation source operable to emit at least one wavelength of electromagnetic radiation, a detector operable to detect the wavelength of electromagnetic radiation, a polycrystalline transparent ceramic component transparent to the wavelength of radiation, and a flowline between the electromagnetic radiation source and the detector having at least a portion of a wall formed from the polycrystalline transparent ceramic component, the flow line operable to permit the flow of a drilling fluid. Such a sensor may be used in a logging while drilling or measuring while drilling apparatus. The also disclosure relates to a wireline measurement apparatus including a sensor comprising a polycrystalline transparent ceramic component. The disclosure further relates to a cast logging sensor or tool component comprising a polycrystalline transparent ceramic component, wherein the sensor component has a shape not obtainable from a single crystal using machining techniques.
Abstract:
Downhole tool is provided that includes a body, an intake port for receiving fluid from external the body, a pump, a filtration device, and an exit port. The pump is in fluid communication with the intake port for withdrawing fluid through the intake port. The filtration device has a particulate removing filter, and a flow line extending from the intake port to the filtration device. The filtration device is contained within the body and is in fluid communication with the intake port. The exit port is in fluid communication with the filtration device for ejecting the fluid to external the body.
