Abstract: A method for transforming an earth formation and/or production equipment based on correcting nuclear magnetic resonance (NMR) data to account for partially water-saturated rock includes: receiving NMR logging data having echo-trains for an earth formation; inverting the echo-trains to provide transverse relaxation time constant (T2) distributions for various components of fluid in the earth formation; substituting a T2 distribution for mobile water of fully water-saturated rock for a T2 distribution for mobile water of partially water-saturated rock based on values of the mobile water T2 distribution of partially water-saturated rock and a total porosity constraint; summing the T2 distribution for mobile water of fully water-saturated rock and a T2 distribution for an immobile water component of the fluid to provide a T, distribution for fully water-saturated rock; and transforming the earth formation and/or the production equipment based on a parameter derived from the T2 distribution for fully water-saturat

Abstract: A method for estimating an amount of hydrocarbon in an earth formation having a kerogen includes determining a pore size in the kerogen at or below which capillary condensation will occur, the determining being performed using a processor. The method also includes calculating an amount of hydrocarbon liquid condensate in pores of the kerogen based on capillary condensation using the determined pore size, the calculating being performed using the processor. The method further includes estimating the amount of hydrocarbon in the earth formation using the calculated amount of hydrocarbon liquid condensate, the estimating being performed using the processor.

Abstract: An apparatus for use in a wellbore may include a tool having a first section configured to receive a core and a second section configured to collect a gas escaping from the core. The apparatus may also include a sensor associated to provide signals relating to a property of gas. In one aspect, the second section may be removable and may be pressurized. The apparatus may also include a recorder that records data representative of the signals received from the sensor. The recorder may record data while the tool is retrieved from the wellbore. A method for estimating a parameter of interest of a formation includes retrieving a core from the formation, collecting a gas escaping from the core as the core is retrieved to the surface, and measuring at least one property of gas while the core is retrieved to the surface.

Abstract: A method includes acquiring formation fluid sample information including pressure, volume, and temperature. Monotonic formation fluid information is extracted from the formation fluid sample information and a pressure, volume, temperature information set is constructed. A curvature sequence is estimated using a first partial derivative and a second partial derivative of pressure with respect to volume. A first maxima is estimated from the curvature sequence, and the formation fluid property is estimated using the estimated first maxima. A method may include a volume acceleration sequence estimated using a first partial derivative and a second partial derivative of the volume with respect to pressure. A first maxima is estimated from the volume acceleration sequence, and the formation fluid property is estimated at least in part by using the estimated first maxima. A method may include establishing a first linear regression model and predicting a confidence interval.
