The present invention relates to a method for verifying a well model, comprising the steps of receiving stored well data of an existing well, forming a model based on the received well data, submerging a tool for performing a work task into the existing well, wherein the tool is arranged to sense present well characteristics when submerged, receiving tool data corresponding to the presently sensed well characteristics from the tool, said tool data representing downhole properties relevant to downhole operation and performance of the tool, and performing a confirmation check by comparing the well data of the model with the tool data. Furthermore, the present invention relates to a well model verifying apparatus, to a well model verifying system and to a computer readable storage medium.

Method and apparatus for verifying a well model

The present invention relates to a method of visualizing a downhole environment using a downhole visualization system. The downhole visualization system comprises a downhole tool string comprising one or more sensors, a downhole data processing means for processing the sensor signals to provide sensor data, an uphole data processing means for uphole processing and visualization, and a data communication link operable to convey the sensor data from the downhole data processing means to the uphole data processing means, the sensors being capable of generating sensor signals indicative of one or more physical parameters in the downhole environment. The downhole visualization system further comprises a downhole data buffering means capable of receiving the sensor data from the downhole data processing means and temporarily storing the sensor data in the downhole data buffering means.
