    Abstract: In the preferred embodiment of the invention disclosed herein, a new and improved well tool which is adapted to be coupled in a drill string adjacent to a drill bit includes inner and outer telescoping members which are cooperatively arranged to define an expansible sample chamber for entrapping a discrete sample of drilling mud from a borehole adjacent to the drill bit in a drill string upon telescoping movement of the inner and outer members. Valve means are cooperatively arranged between the telescoping members for selectively closing the sample chamber upon further movement of the telescoping members to expand the sample chamber. In this manner, by coupling force-measuring means to a drill string coupled to the tool the force required to fully expand the chamber is measured for providing a surface indication which is indicative of the percentage of gas entrained in the collected sample.

    Abstract: In the representative embodiments of the apparatus of the present invention disclosed herein, one or more unique sampling devices are arranged between the upper and lower telescoping members of a typical slip joint which is tandemly connected in the drill string preferably a short distance above the drill bit. Each of these fluid samplers includes telescoping piston and chamber members defining an enclosed sample chamber which is expanded in response to extension of the slip joint members. Valve means are cooperatively arranged with each of the sampling devices for admitting a predetermined volume of drilling mud into the sample chamber each time the slip joint is extended. By moving the drill string so as to expand the sampling chamber, the pressure of the entrapped sample is reduced to at least the saturation pressure of a gas-containing drilling mud at the borehole ambient temperature. By measuring the force required to expand the sampling chamber, the presence or absence of formation gas in the drilling fluid can be determined; and, if desired, these force measurements may be used to derive quantitative measurements which are representative of the percentage of gas entrained in the discrete sample.

    Abstract: A radiation gauge for measuring fluid densities is disclosed, which is particularly useful in monitoring the density of multiple regime fluids flowing through conduits. The gauge includes a radiation source which projects a radiation beam to a detector through a length of conduit or pipe containing a continuous stream of the fluid under investigation. The conduit or pipe includes a relatively gentle curve in the measuring area in order to minimize the disruption of the flow of fluid within the conduit, and in order to minimize the amount of steel or conduit wall material which must be penetrated by the radiation beam. The path length traversed by the radiation beam is selected to maximize both the magnitude and the signal-to-noise ratio of the output information signal, and to maximize the resolution of the gauge.
