Abstract
This article provides an analysis of the process and optimization of horizontal wellbore tracking using geosteering control. Recently, the issue of high-quality and efficient drilling of wells through the reservoir and determining the position of the wellbore in the formations has been raised. In this regard, complex data analysis is used based on a 3D geological model and special software for well geosteering. In preparation for drilling a well, it is necessary to prepare voluminous, comprehensive information on previously drilled wells in a particular field and upload the results of seismic surveys. The article also describes an analysis of activities at various stages of drilling support, starting with geophysical reference and opening the target formation with the transport section.
When drilling a horizontal section of a well, geosteering software is used while drilling wells, equipped with various tools, one of which is the 2D synthetic logging method. The method is based on the superposition of logging curves of a previously drilled reference vertical well and a directional well with a horizontal end currently being drilled. The two-dimensional synthetic logging method is the main and most optimal way to optimize the placement of wells with horizontal completion when drilling terrigenous reservoirs in Western Siberia.
