Abstract: A system for drilling a wellbore includes a prediction unit operable to predict a change in a drilling event while the wellbore is being drilled and prior to the drilling event change occurring. The prediction unit monitors surface and downhole data and well inflows to predict drilling events. The prediction unit may activate alarms for predefined drilling conditions, such as a kick alarm to provide an early warning of a dangerous influx of formation fluids into the wellbore.

Abstract: Embodiments of the present invention relate to a method to determine formation measurements, the method comprising placing a sample in a reservoir, removing aliquots from the reservoir containing the sample or continuously monitoring the reservoir or headspace as the sample and reservoir equilibrate and analyzing the aliquots or readings sufficient to provide diffusion measurements.

Abstract: Methods and apparatus are provided to measure isotopic characteristics of a number of sample types. Embodiments of the invention combine novel and existing components to produce more accurate isotopic information. Further, embodiments of the invention allow for isotopic readings to be taken and analyzed outside of a laboratory. An example of such an embodiment is an apparatus comprising a combustion furnace; a reactant tube passing through the combustion furnace; an injector coupled to one, or a combination of, the combustion furnace, and reactant tube, to introduce a sample; a laser isotopic measurement device coupled to the reactant tube on the exit end; and a processor electrically coupled to one, or a combination of, the injector, the combustion furnace, the reactant tube, and the isotopic measurement device, in which a carrier gas transports the sample through the apparatus.

Abstract: A method for identifying annular gas sources in a wellbore are disclosed. In one embodiment, the method comprises providing a set of parameters, wherein the set of parameters corresponds to depths in the wellbore. In addition, the method comprises analyzing annular gas in the wellbore to provide isotopic data of the annular gas. The method further comprises correlating the isotopic data to the set of parameters to identify the annular gas source.

Abstract: A multivariate optical element (MOE) calculation device is used in an apparatus for determining a property of petroleum in real time flowing in a pipe in petroleum field stream pipes or pipe line. Multiple apparatuses are provided for determining the amount of each of a plurality of properties. An internal reflectance element (IRE) is used to determine the property of the petroleum from a surface of the petroleum flowing in a pipe. A cleaning apparatus is provided to clean the surface of the IRE in the pipe and a turbulence generator is provided in the pipe to insure homogeneity of the petroleum being analyzed prior to analysis. A bellows may be provided the apparatus housing to compensate for pressure differentials between the housing and the flowing petroleum in the pipe. Various embodiments are disclosed.

Abstract: A method for analyzing reservoir fluids in connection with a drilling operation includes determining composition and isotopes of injection fluids injected into a wellbore during a drilling operation and production fluids recovered from the wellbore during the drilling operation. Reservoir fluids from a reservoir intersected by the wellbore are characterized based on the composition and isotopes of the injection fluid and of the production fluid.
