Abstract: A method for measuring gas volume during mudlogging of a subterranean field operation may include obtaining measurements for a plurality of parameters associated with a core sample retrieved from a subterranean formation, where the plurality of parameters are measured while the core sample is under downhole conditions, and where the plurality of parameters comprises a volume of fluid in a gaseous state. The method may also include applying the measurements to an algorithm to generate a calibrated algorithm, where the calibrated algorithm is used to generate an output based on measurements made during the mudlogging.

Abstract: One embodiment of a method of performing a test on a core sample comprises transferring at least a portion of a core sample from a first core containment vessel to a second core containment vessel. The core sample is maintained at a substantially equivalent pressure or placed under a higher pressure during the transfer of the core sample from the first vessel to the second vessel. The method further comprises performing a test on the core sample in a measurement region of the second vessel.

Abstract: A method comprises determining stratigraphic correlations between two or more sets of stratigraphic measurements. Each set of stratigraphic measurements is obtained from a different lateral well in a region.

Abstract: A method of transferring at least one subterranean core sample from a retrieval vessel to a testing vessel can include removing at least one pressure barrier on the retrieval vessel using a linear actuator while maintaining a sampling pressure on the at least one subterranean core sample at which the at least one subterranean core sample is taken from a subterranean formation. The method can also include pressurizing the testing vessel to the sampling pressure using the linear actuator, and transferring the at least one subterranean core sample from the retrieval vessel to the testing vessel. The method can further include sealing the testing vessel with the at least one subterranean core sample at the sampling pressure, where the testing vessel allows the at least one subterranean core sample to be tested while the at least one subterranean core sample is maintained at the sampling pressure.
