Evaluating high-pressure high-temperature (HP/HT) wells has become increasingly challenging. As the wellbore temperatures exceed the continuous operating specification of available sensors and electronic components, standard deployment and data acquisition methods are no longer sufficient. Nearly all practical methods of protecting the sensors and electronics from temperature are time constrained. Therefore it is necessary to explore all options to acquire a maximum amount of data in a finite amount of time downhole. This paper will discuss the equipment and processes necessary to provide critical formation evaluation in the formidable HP/HT environment.
