Abstract
The present invention is directed to an apparatus and method for estimating the value of a parameter of the formation face being penetrated by the drill bit in a drilling operation. The present invention is particularly useful for providing real-time, contemporaneous data concerning the formation face being penetrated for use by the drilling operator or geologist in modifying the drilling operation. The present invention provides a system for estimating the value of one or more parameters of the formation face being penetrated by measuring-while-penetrating one or more measurable parameters of the formation face being penetrated and comparing these values to a data base comprising sets of correlated values for formation parameters of other borehole locations, each set comprising at least a value of the measured parameter and of the parameter of interest. Furthermore, the present invention provides a method and apparatus capable of constantly updating the data base as the borehole is drilled to constantly improve the data base and the estimated values.
