Azimuthal LWD Tools Potential in Horizontal Wells

Azimuthal LWD tools allow to obtain a lot of of information which necessary for a successful horizontal well making and evaluation of the reservoir properties exposed by this well. However, it should be drilled with the geopilot for high-quality data records by these tools. A wide range of azimuthal tools from different service companies provides an opportunity to select the most appropriate for specific tasks. The main results of the azimuth data recording are images of physical properties, caliper data and geosignal. Images of the resistance in horizontal wells have a high enough resolution and allow solving a number of problems. Caliper measurement obtained by azimuthal tools like lithodensity and neutron logging can be a reliable replacement for traditional acoustic caliper. For the preventive geosteering It is impossible to do it without of data obtained by the azimuth tools: images allow us to determine the angles of layer intersection and to map faults, the value of geosignal allows to stay in the target zone. Thus, the azimuthal LWD tools have great possibilities so that they everywhere used while drilling horizontal wells.
