Effect of Fracturing Fluids on Fracture Conductivity

Abstract: Measurements and predictions of the effect of fracturing fluids on fracture conductivity were made. The residue from guar polymer was found to greatly reduce fracture conductivity under some conditions, and these conditions could be predicted based on residue volume measurements. Some other polymers were found to decrease fracture conductivity because insufficient breaker was present in the simulated fracture. Fluid loss additives at normal concentrations had negligible effect on fracture conductivity. The technique developed to simulate reservoir fracture conditions can be used to test any fracturing fluid for its effect on fracture conductivity.

Three-dimensional seismic imaging of Paleogene dike-fed submarine volcanoes from the northeast Atlantic margin

Abstract: We use three-dimensional seismic data to describe the architecture of shallow intrusive igneous sill and dike complexes intruded into the upper crust as well as the internal and external geometry of extrusive conical igneous mounds that were fed by the magma conduits. The conical mounds accreted on the seabed, directly above the tips of the basaltic dikes, between 54.9 and 54.6 Ma. In plan view the mounds are broadly circular, 1–1.7 km in diameter, and have a relief of 50–300 m. They occur above a complex network of linked cuspate-shaped sills and dikes intruded into Paleocene and Cretaceous sediments of the Faeroe-Shetland Basin, northeast Atlantic margin. The highly organized internal structure, consisting of bulbous layers arranged concentrically around a central axis, along with the clear vertical link to the underlying sills and dikes, indicates that they most likely represent pillowed basaltic lava and hyaloclastite mounds that were fed by the dikes and extruded onto the seafloor. Mounds of similar external geometry have been described from sidescan sonar images above active spreading centers in oceanic settings. However, such structures are rarely recognized in passive margin settings, and prior to this investigation our knowledge of their three-dimensional internal geometry has been largely speculative.

Thermodynamics of Charge-Density Waves in Quasi One-Dimensional Conductors

Abstract: Simple methods are described to evaluate quantitatively the influence of charge-density-wave fluctuations on the thermodynamics of quasi one-dimensional conductors, and are applied to experimental data for ${\mathrm{K}}_{0.3}$Mo${\mathrm{O}}_{3}$. These fluctuations are found to affect strongly the magnetic susceptibility and electronic entropy and heat capacity over a large temperature range.
