摘要： Earth-boring tools may comprise a body comprising a first region and a second region. The first region may be located closer to a rotational axis of the body than the second region. A first cutting element may be located in the first region and a second cutting element may be located in the second region. A first polycrystalline table of the first cutting element may be substantially free of catalyst material to a first depth and a second polycrystalline table of the second cutting element may be substantially free of catalyst material to a second, greater depth.

摘要： The seal has a base ring that expands with the underlying supporting tubular. Extending from the base ring is a pleated structure with segments folded over each other so that the run in shape is small and up against the supporting tubular for run in. The pleated segments can have internal stiffeners that also add a bias radially outwardly when the structure is freed to move in that direction. A retaining band keeps the assembly retracted until tubular expansion defeats the band to allow the unitary structure to move out radially to the wellbore or surrounding tubular. The pleated portion unfolds and spans outwardly from the base ring to retain pressure differential in one direction while allowing fluid flow in the opposite direction. The assembly can be attached to a swage device so that pressure from above into the set seal can drive one or more swage members to expand a tubular.

摘要： A laser spectroscopy system can determine the identity and/or quantity of a component of a fluid at a remote location such as downhole in a wellbore or inside a pipeline, particularly at high temperature, e.g. from about 75 to 175°C. The system includes a fiber laser doped with a rare earth element (e.g. Nd 3+ , Tm 3+ , Er 3+ , Th 3+ , Ho 3+ , Yb 3+ , Pr 3+ ) and generates light in a wavelength between about 900 to about 3000 nm. The system may analyze a drilling mud such as an oil based mud or crude oil, and may detect components such as methane, ethane, carbon dioxide, hydrogen sulfide and the like.

摘要： The disclosure, in one aspect, provides a method for estimating a property of a fluid that includes: pumping an ultraviolet (UV) light into a fluid withdrawn from a formation downhole at a wavelength that produces light due to the Raman effect at wavelengths that are shorter than the substantial wavelengths of fluorescent light produced from the fluid; detecting a spectrum corresponding to the Raman effect light ("Raman spectrum"); and processing the detected Raman spectrum at one or more selected wavelengths to estimate a property of the fluid. In another aspect, the disclosure provides an apparatus that includes a laser that induces UV light at a selected wavelength into a fluid in a chamber, a detector that detects Raman scattered light at wavelengths shorter than the wavelengths of the fluorescent light scattered by the fluid, and a processor that analyzes a spectrum corresponding the Raman scattered light at a selected wavelength to estimate a property of the fluid.
