Abstract


The article shows an approach to taking into account the possible risks of not confirming the structural surfaces of target objects during drilling support at the hydrocarbon fields of JSC Orenburgneft. In the absence of the possibility of conducting more precise seismic exploration at the developed fields, the only possible approach is to work with the current materials. Understanding the quality of the initial material and taking into account the risks based on this is crucial when planning the drilling strategy at the field. This approach allows for correct drilling planning in most cases and is cost-effective, as it does not require complex work.

Key words:

types of seismogeological risks, risk assessment methodology for production drilling
