Abstract: A video conference display method includes: an MCU obtaining a stereoscopic video source of a conference site where a first terminal device in a video conference is located; and the MCU sending the stereoscopic video source to one or more other terminal devices, except the first terminal device, in the video conference, wherein the stereoscopic video source is used by one or more other terminal devices for non-screen displaying of the conference site where the first terminal device is located in one or more conference sites where the one or more other terminal devices are located. The scheme solves the problem of poor user experience of video conferencing, improves the sense of being present at the video conference, has no other differences from an on-site conference except that the entities cannot be touched, improves the user experience, and is an important step towards widely popularizing the video system.

Abstract: Systems and methods for fracturing a formation are provided. A method includes generating a subsurface model including the production formation and a zone proximate to the production formation. A number of scenarios are simulated in which a volumetric change is created in the zone proximate to the production formation. A scenario is selected from the plurality of scenarios to stimulate the production formation. The scenario is performed to create a fracture field in the production formation.

Abstract: Systems and methods are described for fracturing a production formation. A method includes drilling a well into a zone proximate to a production formation, and increasing a volume of the zone through the well in order to apply a mechanical stress to the production formation.

Abstract: Method for determining reservoir permeability from Stoneley wave attenuation extracted from conventional sonic logs by inversion of the full Biot wave equations for a porous medium. Frequency-dependent Stoneley-wave attenuation is extracted by analyzing array sonic measurements. Then, based on Biot's full theory applied to a borehole model and the standard logs (gamma ray, caliper, density, neutron, resistivity, sonic, etc.), a simulation model with the same parameters as the Stoneley-wave measurements is built. Next, a theoretical Stoneley-wave attenuation is computed for a given permeability. Finally, reservoir permeability is determined by comparing the modeled Stoneley-wave attenuation with the measured Stoneley-wave attenuation by an iterative inversion process.
