GSSPE Presentation on
Hitting the Sweetspot:
Developments in Reservoir Navigation
Dr. Andreas Hartmann
Placing the wellbore in the optimal spot is required to maximize the production of reservoirs. Reservoir navigation, also know as geosteering, is key to achieve this goal. Real-time information from the bottom hole assembly will be transmitted to surface, processed, and interpreted to place wells relative to geologic features of the reservoir, such as top and base of the reservoir. Starting point for placing the well is always the definition of the well placement objective. Based on that, an approach to steer the well is selected. Several methods are part of the standard toolbox. Traditionally, the primary purpose in is the avoidance of reservoir exit, requiring the capability of detecting remote beds that are not intersected by the wellbore. Induction type resistivity measurements used in logging while drilling (LWD) application do provide this capability, current technologies typically allow interpretation of the boundaries nearest to the wellbore.
More complex reservoir geometries and advanced applications such as mapping of reservoir thickness require a new approach. In recent years new technology has become available that is sensitive to formation further away from the wellbore. This opens up new applications and changes the way the task of geosteering is approached. The technological development will be discussed. Advances include development of the sensor hardware as well as the new algorithmic concepts to interpret large amounts of data coming from the BHA. The technology has now reached maturity and examples will be used to demonstrate this.
About the Lecturer
Andreas Hartmann earned a MSc in Geophysics (Bremen University) and obtained his doctor of natural science at RWTH Aachen University. Andreas gained experience by a number of assignements in various disciplines, including a field geophysicist in marine seismics, a scientist in Geothermics and Petrophysics. He spent 11 years at Baker Hughes in the R&D department, with his latest assignment as project manager for multiple Logging-While-Drilling products on Resistivity Imaging, Near Bit Gamma and Resistivity, Extra Deep Reading Resistivity, and Azimuthal Propagation Resistivity.
