An apparatus and method for determining a property of an earth formation using a radial basis function derived from a catalog of rock samples. Parameters of a Thomeer capillary pressure fitting curve are derived and used for analyzing rocks with unimodal or multimodal pore size distributions.

Method and apparatus for predicting petrophysical properties from NMR data in carbonate rocks

An apparatus made according to one embodiment may include a first chamber configured to receive fluid under pressure and to compress a gas in a second chamber in pressure communication with the first chamber, wherein the second chamber is configured to discharge the fluid out from the first chamber when pressure of the fluid in the first chamber is reduced.

Apparatus and method for formation testing

A method of estimating a formation pressure in a wellbore is provided that in one aspect includes measuring a hydrostatic pressure at a selected location in the wellbore, and estimating supercharge pressure as a function of time using a forward model that utilizes the hydrostatic pressure and at least one property of mud in the wellbore that is a function of time. In another aspect, the method may estimate an initial formation pressure at a selected location in a wellbore by obtaining a hydrostatic pressure and at least three formation pressure measurements at three separate times at the selected location, and estimating the initial formation pressure using the hydrostatic pressure, the three pressure measurements and an internal mudcake parameter.
