    Abstract: A method and apparatus for drilling at least one wellbore from an offsite location is provided. Each wellbore is located at a wellsite having a drilling rig with a downhole drilling tool suspended therefrom. The downhole drilling tool is selectively advanced into the earth to form the wellbore. The downhole drilling tool is operated according to a wellsite setup. Wellsite parameters are collected from a plurality of sensors positioned about the wellsite. The wellsite parameters are transmitted to an offsite control center. The offsite control center performs an analysis of the wellsite parameters and automatically adjusts the wellsite setup from the offsite control center based on the analysis.

    Abstract: A method of using jarring tool in a wellbore, where the jarring tool is electrically activated to apply an impact force transmitted to at least another tool in the well. The method may further comprise operating a hydraulic mechanism in response to electrical activation of the jarring tool to cause a first member of the jarring tool to be moved to collide with a second member of the jarring tool to apply the impact force. Also, the method may involve electrically activating the jarring tool by communicating at least one command over at least one electrical conductor to the jarring tool.

    Abstract: A fluid analysis system for use downhole comprises an input light signal that is directed through a fluid sample housed in a sample cell. The input light signal may originate from a plurality of light sources. An output light signal from the sample cell is then routed to one or more spectrometers for measurement of the represented wavelengths in the output light signal. The output of the spectrometers is then compared to known values for hydrocarbons typically encountered downhole. This provides insight into the composition of the sample fluid. Additionally, the light from the light sources can be routed directly to the one or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole.
