Abstract
Aim. The article presents selected results and techniques developed in the process of drilling horizontal wells and fishbone wells in an oil and gas condensate field in Eastern Siberia.
Materials and methods. The risk analysis of the intrusive bodies and traps presence in the drilling area was carried out, the design petrophysical model has been refined, and corrections for gas in high-permeability reservoirs have been substantiated and introduced. The methodology for using smart pilot wells and methodology for estimating the target flow rate in the process of drilling wells have been developed and implemented.
Results. The drilling results of more than 60 wells were analyzed and evaluated. Final experience and the analysis made it possible to increase the efficiency of drilling new wells in this field. The author’s methods for forecasting the flow rate and changing the design of wells depending on the calculated geological potential have been tasted in practice. The positive effect of this methods has been proven.
Conclusion. The experience gained and the results of the decisions make it possible to replicate the project team’s approaches to other assets in Eastern Siberia with a similar geological structure.
