Abstract: A formation evaluating system including a sonic sensor device attached to a drill string adjacent to a bit includes a sonic source and a first sonic receiver aligned adjacent to the sonic source, and a second sonic receiver aligned with a horizontal offset X. Three kind of two-way trip times are measured: from the sonic source to a) the first receiver after a reflection at the borehole wall, b) the first receiver after propagation in a layer below the borehole wall, an invaded zone, and a reflection at an interface below the borehole wall, and c) the second receiver after oblique propagations in the invaded zone and a reflection at the interface. After determining a sonic speed in the drilling mud and a sonic speed in a matrix of the invaded zone, a porosity and a thickness of the invaded zone are estimated based on a time average equation.

Abstract: The invention is directed to an automated Marsh funnel and Marsh funnel apparatus or system, and an automated method for measuring the Marsh funnel time and density of drilling muds and calculating other rheological properties from Marsh funnel time and mud weight. The system measures and reports rheological properties of drilling muds in real time and faster, more conveniently, and more accurately than conventional manual methods.

Abstract: The disclosed subject matter broadly involves a device and a method for determining characteristics of a rock sample. The rock sample can be provided in a sample receptacle. Length of the rock sample can be automatically determined when the rock sample is in the sample receptacle. A current can be provided through the rock sample, which, along with the determined length, can be used to determine one or more of resistance-, porosity-, and permeability-related characteristics of the rock sample.
