Description

The Tolteq™ symmetric propagation resistivity (SPR) MARK II tool offers real-time logging-while-drilling (LWD) resistivity combined with advanced, high-bandwidth measurement-while-drilling (MWD) tools. The tool creates high-quality resistivity logs with both phase and attenuation measurements in real time—measurement capabilities as well as multiple depths of investigation and vertical resolutions help with the drilling process. With a total of eight curves recorded into memory, the SPR MARK II tool has extremely high-resolution memory data with fast data dump capability. This feature enables our field operators to create high-resolution logs after the run is complete with no impact on drilling time. The eight resistivity measurements can be further enhanced by applying borehole corrections in ToolTracker™, a user-friendly data handling application.

The SPR MARK II features many upgrades including an increased temperature rating of 160˚C for high temperature applications, a more durable design that increases tool life in harsh applications, and a new universal surface kit for easier rigsite operation. In addition, the SPR MARK II offers a rugged, fixed connection option based on the proven SureMate™ interconnection for reliable performance in challenging drilling conditions, while an improved wet connect provides a rapid deployment option. The tool is now available as an integrated option with the NOV™ VectorZIEL™ rotary steerable system (RSS).
