Abstract: A measurement device makes measurements on a region of investigation in which a native fluid or complex fluid (e.g., emulsified fluid) has been replaced by a fluid of different viscosity. Various methods such as core flooding, pressure cycling, centrifuging, or imbibition may be used to replace the native fluid. The replacement fluid may include alkanes, alkenes, or some combination of those, and is preferably non-polar. The replacement fluid may mix with the native fluid within the pores to produce a mixture having a different viscosity than the native fluid. Measurements can be made on a sample in a lab or on an isolated region of a subsurface formation. Standard measurement techniques such as the Amott-Harvey technique or the United States Bureau of Mines technique may be used. Alternatively, NMR measurements may be performed. A parameter such as wettability and relaxivity is estimated using data obtained by the measurement device.

Abstract: In-phase and quadrature components have different relationships with some important petrophyscial parameters, such as water saturation and mineral cation exchange capacity (CEC). In clay-containing subterranean rock formation such as shaly sand formations, these parameters can be estimated using different components of array induction tool data combined with other knowledge about the clay-containing formation. Some parameters, such as mobility and fraction of counterions are valid in cases where the pore water solution is an electrolyte of NaCl.

Abstract: A tool having two current electrodes, three or more voltage electrodes, and a measurement device capable of making electrical measurements is provided, along with a sample. With electrical connectivity to the sample, one current electrode is disposed at one location on the sample while the other current electrode is disposed at another location on the sample, and the three or more voltage electrodes are disposed on the sample intermediate the two current electrodes. An electric current is passed through the sample. The measurement device is used to make a first set of electrical measurements that involve a first pair of voltage electrodes and to make a second set of electrical measurements that involve a second pair of voltage electrodes. The first set of electrical measurements is compared to the second set of electrical measurements. It is inferred whether the sample has heterogeneous electrical properties using the compared electrical measurements.
