CO2 Gas Extraction through Rotary Drilling and Associated Problems (original) (raw)

2005, Selcuk University Journal of Engineering, Science and Technology

Drilling wells are classified upon the purpose, depth, location, and the matter of material to be explored. Drilling methods also vary. One of which is rotary drilling method. The aim of this study is to outline the processes during the rotary drilling utilized for the extraction of CO2 gas. The problems encountered during and after drilling were identified and solution schemes were proposed. As a practical application, the drilling activities in Kemerhisar district were chosen. The drilling operations through the CO2 bearing formation of Kemerhisar district was followed in a particular borehole, down to the depth of 220 m, and the fragments coming from the bottom of the hole were logged on a one-meter basis detail. During drilling operation, the performance of equipment were monitored and such properties as drilling speed, drilling fluid properties, gas emissions and water intakes were recorded. Upon those, well design and development were carried out. An appropriate drilling rig w...
