摘要： A system and a method manage temperature in a wellbore. A thermal barrier may be positioned within the drill pipe and/or the drill collars to obtain a desired downhole temperature and/or control the effect of thermal energy in high-angle and horizontal wellbores. Downhole measurements, such as real-time measurements and/or recorded measurements, may be used to update models, such as steady state models and/or dynamic models. The downhole measurements may validate the static temperature gradient and may provide information about the thermal characteristics of the one or more formations in which the wellbore is located.

摘要： A logging tool capable of making different types of measurements is provided, and a plurality of measurements on a formation are obtained. Certain mineral properties of the formation are assumed and a mixed properties theorem for the formation is invoked. Upper and lower velocity limits for sonic waves traveling through the formation are determined using the above information. Biot's constant is also computed using the above information. LWD data on the formation is obtained and an effective stress is determined. A total stress is determined and, from that and the other information, a pore pressure is determined.

摘要： This control process allows buyers to select vendors based upon their project and geographic proximity. Once potential vendors are identified and selected purchase orders are generated and communicated to the vendors. Based upon the project, vendors are identified and purchase orders generated for most if not all of the required products, tools, and materials that are relevant to the operations and project. Additionally, the control process can be filtered according to customizable buyer priorities and buyer feedback.
