TL;DR: The behavior of injected fluids and hydraulic fractures in non-cohesive soils was investigated using laboratory experiments and two field experiments as mentioned in this paper, where a viscous guar gel was injected into fine-grained sand in the laboratory; of eight tests, two produced vertical fractures and a third produced both horizontal and vertical fractures.

TL;DR: In this paper, preliminary results of a proton nuclear magnetic resonance study of water and oil drainage under gravity through a sand column are reported, where the evolution of the proton magnetization and its spin-spin relaxation time T2 are given as functions of drainage time.
Abstract: Preliminary results of a proton nuclear magnetic resonance study of water and oil drainage under gravity through a sand column are reported. Evolution of the proton magnetization and its spin–spin relaxation time T2 are given as functions of drainage time. It was found that the bulklike fraction of the liquids drains out quickly, while the pendular and surface fractions drain slowly until an equilibrium is reached. The “undrainable,” residual liquid fraction was observed to be ∼6% and ∼48% of its initial value for water and light oil, respectively. The proton T2 of water and oil in different environments are analyzed by employing the fast exchange model. This method of monitoring the drainage of two liquids can be easily adapted to study the spacial and temporal evolution of the liquids in the presence of a gas phase.

TL;DR: In this paper, a new method is presented for damaged formation characterization based on a new constant-head hydraulic solution which considers formation alteration effects, which simulates alteration effects by considering a gradual variation of permeability with radius in the form of a power relationship.

TL;DR: In this paper, a water proton spin-lattice relaxation study of the spin-label molecules 2,2,6,6- tetramethyl-4-acetamido-piperidine-1-oxyl (TMAPO) solution in glass pores of 127 nm diam reveals that when the porous glass is hydrated with a 1 mM TMAPO solution, the concentration in pore water is maintained constant during dehydration.
Abstract: A water proton spin-lattice relaxation study of the spin-label molecules 2,2,6,6- tetramethyl-4-acetamido-piperidine-1-oxyl (TMAPO) solution in glass pores of 127 nm diam reveals that when the porous glass is hydrated with a 1 mM TMAPO solution, the TMAPO concentration in pore water is maintained constant during dehydration. However, it was observed that if the pore diameter is 49.1 nm or smaller, the Langmuir isotherm is not applicable, although the surface-to-volume ratio is larger. The observed proton relaxation’s dependence on pore volume-to-water volume ratio V0/V, is in excellent accord with the results of the electron paramagnetic resonance experiments and supports a model based on the fast exchange of water between nonequivalent environments.

TL;DR: In this paper, the authors used low-temperature geo-thermometers such as vitrinite reflectance and fluid inclusion response to determine the fracture zones for Xingouzhui strata, an Eocene Age formation in the Tuoshi Oil Field of central China.
TL;DR: A reverse vertical seismic profiling/crosswell seismology (RVSP/CSW) inverse technique which is based on an elastic model has been developed to quantify the dynamic mechanical parameters and map the structural anomalies in a solid rock medium around an underground opening as discussed by the authors.
