Abstract: A method for performing a formation fluid test in a borehole penetrating a subsurface formation includes disposing a fluid tester in the borehole, extracting a sample of fluid from the subsurface formation using the fluid tester, and analyzing the sample using the fluid tester to provide test data for a process used to analyze the sample. The method also includes fitting an equation to the test data and calculating a ratio of a first derivative of the equation to a second derivative of the equation. The method further includes continuing to extract the sample from the subsurface formation in response to the ratio indicating a clean sample will be forthcoming and terminating the extracting of the sample from the subsurface formation in response to the ratio indicating a clean sample will not be forthcoming.

Abstract: A method for forming a wellbore in an earth formation includes positioning a drill string in a wellbore; the drill string including a bottom hole assembly (BHA) that includes a steering unit, one or more sensors responsive to one or more formation properties, and one or more sensors responsive to the current orientation of the BHA in a wellbore. The method also includes receiving information from the BHA related to the formation properties and information related to a current orientation of the BHA in the wellbore and processing the information using computing device that is either a programmable optical computing device or a quantum computing device. The computing device calculates the position of formation features with respect to current wellbore position in real time and compare the current position to a prescribed path.

Abstract: An apparatus for estimating a property of a downhole fluid includes a carrier configured to be conveyed through a borehole penetrating the earth, a fluid extraction device disposed at the carrier and configured to extract a sample of the downhole fluid, and a probe cell having a window to receive the sample. The apparatus further includes a light source to illuminate the sample through the window with light photons, and a photodetector to receive light photons through the window that have interacted with the downhole fluid and generate a signal indicative of an amount of the received light photons. The generated signal is indicative of the property. The photodetector has an optical cavity having a semiconductor that has a difference between a valence energy band and a conduction energy band for electrons that is greater than the energy of each of the received light photons.
