Analysis of the Experience of Geosteering and Making Erroneous Decisions
at Offshore Field
Author(s): Dmitri Polyakov* and Ayupova Diana
The limited scope of geological exploration of offshore fields is the reason for the high structural uncertainty in any traps. The
lack of a complete set of initial information for well construction requires an innovative approach to planning, drilling and well
support. Geosteering can significantly improve the quality of the horizontal section borehole drilling and is an opportunity
to obtain actual data from the bottomhole. Drilling support allows to quickly make adjustments to the well trajectory due
to changes in the geological conditions. Based on the geological drilling support experience at the analyzed offshore field, in
general the reasons classification for operational adjustments taken during drilling was created. The most common reasons
for changing the planned trajectory and the results of decisions are noted. The analyzed field is complicated by faults.. View More»
