摘要： A method and apparatus for predicting a formation parameter at a drill bit drilling a formation is disclosed. A vibration measurement is obtained at each of a plurality of depths in the borehole. A formation parameter is obtained proximate each of the plurality of depths in the borehole. A relationship is determined between the obtained vibration measurements and the measured formation parameters at the plurality of depths. A vibration measurement at a new drill bit location is obtained and the formation parameter at the new drill bit location is predicted from the vibration measurement and the determined relation. Formation type can be determined at the new drill bit location from the new vibration measurement and the determined relationship.

摘要： A system for transmitting information in a well comprises a tubular string disposed in the well and having a drilling fluid flowing therethrough. A pulser is disposed in the tubular string and transmits a pulse synchronization marker comprising a chirp signal. A surface controller, acting under programmed instructions, detects the chirp signal adjusts a signal decoding technique based on the detected chirp signal.

摘要： Methods and systems for automatically performing a sweep operation in a borehole penetrating an earth formation including conveying a drillstring through a borehole, the drillstring having one or more sensors located thereon, determining that a sweep operation should be performed based on information obtained from the one or more sensors, determining characteristics of a pill to be used for a sweep operation based on information obtained from the one or more sensors, preparing a pill in accordance with the determined characteristics, deploying the pill into the drillstring and conveying the pill through the drillstring, and monitoring the sweep operation while the pill is within the drillstring and verifying the sweep operation. At least one of the determination that a sweep operation should be performed, the determination of the pill characteristics, or the preparation of the pill is performed automatically.
