ABSTRACT:
Determinations are made of the conditions in a fluid-containing well penetrating a fluid-producing subterranean reservoir by isolating an interval in the well which penetrates the fluid-producing reservoir, withdrawing fluid from the interval and determining conditions such as fluid composition, pressure build-up, and temperature in the interval. The interval is isolated with a packing member surrounding an open conduit means extending in the well from the top of the well to a location adjacent the reservoir. Fluid moves from the reservoir into the conduit means and is withdrawn from the conduit means through an opening in the conduit means above and adjacent the lower end of the conduit means. Determinations are made by lowering measuring tools through the tubing string to a location in the well below the opening through which fluid is withdrawn from the conduit means.
