BIT BASED FORMATION EVALUATION USING A GAMMA RAY SENSOR |
摘要 |
<p>A drill bit made according to one embodiment includes at least a gamma ray sensor configured to provide signals representative of a presence and/or amount of a naturally occurring gamma ray source when the drill bit is used for cutting into a formation. A circuit may be configured to process signals from the gamma ray sensor to provide an estimate a parameter relating to the naturally occurring gamma ray source, which may used for purposes such as optimizing drilling parameters and geosteering.</p> |
