摘要： A sample of material is rotated within a pair of parallel, spaced-apart laser beams. Variations in the diameter of the sample are determined with azimuth from the amounts of the laser beams intercepted by the sample as it rotates about an axis perpendicular to the plane of the laser beams. The sample is translated along this axis within the path of the laser beams so that the diameter of the sample is determined for a plurality of spaced-apart planes through the sample perpendicular to the axis of rotation. The deformation of the material with stress is determined by measuring the variations in diameter of the sample as the stress on the sample is changed.

摘要： Measurements of reservoir characteristics of a core sample of a subsurface formation are carried out with the core sample being subjected to pressure cycling. Pore volume changes during such pressure cycling are measured. Pore compressibility is determined from a plot of the measured pore volume change versus pressure. Scanning of the core sample with X-rays each pressure cycle identifies the pressure at which fracturing is initiated.

摘要： Methods for recovering heavy oil are provided. In at least one embodiment, the process includes conditioning a reservoir of interest, then initially producing fluids and particulate solids such as sand to increase reservoir access (“slurry production”). The initial production may generate high permeability channels or wormholes in the formation, which may be used for heavy oil production processes (“hydrocarbon production”) such as cold flow (CHOPS) or enhanced production processes such as SAGD, or VAPEX.

摘要： A method for producing a substantially calibrated numerical model, which can be used for calculating a stress on any point in a formation, accounts for a formation's geologic history using at least one virtual formation condition to effectively “create” the present-day, virgin stress distribution that correlates, within acceptable deviation limits, to actual field stress measurement data obtained for the formation. A virtual formation condition may describe an elastic rock property (e.g., Poisson ratio, Young's modulus), a plastic rock property (e.g., friction angle, cohesion) and/or a geologic process (e.g., tectonics, erosion) considered pertinent to developing a stratigraphic model suitable for performing the desired stress analysis of the formation.
