Covers historical trends and two major aspects of drilling technologies - downhole motors and oil well drilling optimization (KTW-Key Technological Wells drilling method). Using a downhole motor is more efficient, especially in hard formations. Advanced drilling studies have long been conducted in the FSU and are important in reducing drilling costs in marginal reservoirs.
