The aim of this paper is to focus on some basic terms definitions and simple practical calculations.ĭirectional diamond drilling Directional diamond drilling is a special method of drilling into the Earth’s surface in order to explore ore bodies by reaching a specific zone or target and controlling borehole trajectory by special means.ĭirectional borehole A borehole whose trajectory in three dimensions has been designed and consciously directed to reach a target or zone of interest within acceptable limits of accuracy.
Point to point directional drilling software#
Sometimes, even sophisticated software programs do not make simple practical calculations and analysis easy.
On the other hand, a few simple calculations are often helpful in analysis and decision making.
The author’s experience teaching drilling engineering at the Sofia University of Mining and Geology and frequent contact with industry personnel demonstrate the need to establish basic common terms and definitions in order to improve understanding of the process and lessen confusion. Discussion of the factors listed above often runs into difficulties arising from differences in terminological and technical term definition. A close look at its application reveals the most important factors to be considered in drilling programs and bore-hole planning: the tools and equipment to be employed, their technology, borehole design and analysis, manpower experience and overall economy.Īlong with these main factors, understanding the limitations of DDD is crucial for its economic and efficient application. Its application plays an important role and is constantly increasing. of Drilling, Transport and Oil & Gas Production, Mining and Geology U., Sofia, Bulgariaĭirectional diamond drilling (DDD) is powerful technology in the service of the mineral exploration industry.
