Abstract: A bottomhole assembly (BHA) coupled to a drill string includes one or more controllers, and a hole enlargement device that selectively enlarges the diameter of the wellbore formed by the drill bit. The hole enlargement device includes an actuation unit that may move extendable cutting elements o the hole enlargement device between a radially extended position and a radially retracted position. The actuation unit may be responsive to a signal that is transmitted from a downhole and/or a surface location. The hole enlargement device may also include one or more position sensors that transmit a position signal indicative of a radial position of the cutting elements. In an illustrative operating mode, one or more operating parameters of the hole enlargement device may be adjusted based on one or more measured parameters. This adjustment may be done in a closed-loop or automated fashion and/or by human personnel.

Abstract: Apparatus and method for downhole formation fluid sampling include conveying a carrier into a well borehole that traverses a subterranean formation of interest, the carrier having a port and placing the port in fluid communication with the subterranean formation of interest. The method includes urging a fluid into the port using a fluid control device, the fluid containing a formation fluid and a contaminant, generating a first signal indicative of a first fluid characteristic of the fluid using a first test device in communication with the fluid, and generating a second signal indicative of a second fluid characteristic of the fluid using a second test device in communication with the fluid. The first signal and the second signal are processed using a processing device to estimate a level of contamination in the fluid, and a control signal is generated when the estimated level of contamination meets a predetermined value.

Abstract: A method of determining a formation pressure during drawdown of a formation comprises sampling fluid from a formation using a downhole tool. A fluid sample pressure is determined at two different times during the drawdown. The fluid sample pressures are analyzed using a higher-order pressure derivative with respect to time technique to determine the formation pressure during the drawdown. Another method of determining a formation pressure during drawdown of a formation comprises sampling fluid from a formation using a downhole tool. A fluid sample pressure is determined at two different times during the drawdown. The fluid sample pressures are analyzed using at least two analysis techniques to each determine an estimate of the formation pressure during the drawdown.
