    Abstract: Formation testing which may involve circulating mud in a pipe string from a mud pit through a port in the pipe string to a downhole diverter sub, wherein the pipe string is suspended in a wellbore extending into a subterranean formation, operating a downhole pump to pump formation fluid from the formation, wherein the formation fluid comprises gas, and mixing the pumped formation fluid with circulated mud such that a proportion of the pumped formation gas in the circulated mud is maintained below a threshold value.

    Abstract: A method for calibrating a pump assembly is disclosed. The method includes characterizing a pump of the pump assembly to determine a performance characteristics of the pump. The method may also include calibrating a sensor associated with a displacement unit of the pump assembly. Calibrating the sensor may include calibrating the sensor under operating conditions of a first environment and under operating conditions of a second environment. Under the operating conditions of the second environment, the pump can also be calibrated to determine a performance characteristics of the pump at the operating conditions of the second environment. The calibrated pump assembly is then used to draw fluid from a subterranean formation or conduct a formation test.

    Abstract: Collecting temperature data at a plurality of locations along a wellbore, performing thermo-mechanical simulations of a drill string in response to mud circulation wherein the drill string comprises a tool string suspended in the wellbore from a pipe string, determining changes in length of the pipe string due to temperature changes, positionally fixing the tool string at one of the locations, and adjusting the length of the pipe string based on the determined change in length of the pipe string. Positionally fixing the tool string may comprise lowering the drill string a side entry sub of the drill string is proximate a top end of the wellbore wherein the side entry sub is configured to allow a wireline cable to enter a bore of the drill string, positioning the side entry sub above a blow-out-preventer, and closing the blow-out-preventer around the drill string below the side entry sub.
