Dipmeter and borehole image log technology / Технология регистрации показаний инклинометра и изображений в скважине

The ever-increasing energy demand requires recovery from existing fields to be maximized, a process mostly dependent on accurate reservoirmodels. Borehole imaging is one of the fastest and most precise methods for collecting subsurface data (Figure 1). Borehole imaging can feed even millimeter-scale information into these models (Paillet et al., 1990). Increasingly, borehole images can be transmitted and integrated into reservoirmodels while drilling, which is an important step toward real-time field optimization (Sparkman, 2003). Recent advances in modeling software allow the fully integrated use of image data in reservoirmodels for the first time. As a result, the status of borehole image technology is shifting from being a niche application to being a key component of both static and dynamic reservoir models. Technological advances in borehole imaging during the past 5 yr have facilitated these developments. One important area of progress is the introduction of highresolution oil-base imagers (Pavlovic, 2002). The quality of recent images in oil-base mud systems comes close to wireline image resolution. Even more significant is the development of high-resolution loggingwhile- drilling (LWD) tools (Ritter et al., 2004) that now rival traditional wireline images. The latest generation of LWD imaging tools can detect high-permeability streaks only a fewdecimeters thick and can track them for long distances using advanced, image-based geosteering technology (Prosser et al., 2006). <...>
