Abstract: Nuclear magnetic resonance (NMR) gas isotherm techniques to evaluate wettability of porous media, such as hydrocarbon reservoir rock, can include constructing a NMR gas isotherm curve for a porous media sample gas adsorption under various pressures. A hydrophobic or hydrophilic nature of the porous media sample can be determined using the NMR gas isotherm curves. A wettability of the porous media sample can be determined based on the NMR gas isotherm curve. The wettability can be determined for porous media samples with different pore sizes. In the case of reservoir rock samples, the determined wettability can be used, among other things, to model the hydrocarbon reservoir that includes such rock samples, to simulate fluid flow through such reservoirs, or to model enhanced hydrocarbon recovery from such reservoirs.

Abstract: A power-down mode exit control circuit enables a memory device to exit from an initially set power-down mode state using a clock enable signal. Specifically, although a clock enable signal is inputted in an unstable state at an initial operation indicating that a supply of a supply voltage is started, the present invention provides the power-down mode exit control circuit which is capable of escaping from the power-down mode at an internally set correct time. For this, the present invention comprises: a clock enable signal sensor for sensing an activation or deactivation state of a clock enable signal; and a power-down mode exit signal generator for activating and outputting a power-down mode exit signal in accordance with the activation state of the clock enable signal sensed by the sensor, after storing information related to the deactivation state of the clock enable signal sensed by the sensor.
