Forecast of the future prospects of drilling ultra-deep wells in difficult mining and geological conditions of Western Turkmenistan

Abstract

The article defines the prospects for drilling wells in difficult and extreme mining and geological conditions of the Western part of Turkmenistan. The assessment of the current state of prospecting and exploration works in Western Turkmenistan is given. The main problems that drillers will face when drilling complex deep horizons of the red-colored stratum are considered, and general principles and recommendations for overcoming these problems are provided. The applied technical and technological innovations that meet international standards have ensured the successful completion of a number of deep and ultra-deep wells in the fields of the West Turkmen Depression, but have not completely solved the existing drilling problems. The article also provides a number of recommendations for solving these problems. This work contributes to the beginning of the development of a new geological and technological discipline - reservoir pressure management during drilling, and its introduction into practice, which will serve as technical re–equipment and organizational restructuring of deep drilling on a scientific basis.
