Abstracts
A Contractor usually utilizes the available drilling equipment when constructing just one single well. Drilling cost and time consumption in constructing the well MB-1, using the percussion method, and the well MB-2, using the conventional rotary drilling method, call for a separate analysis in order to justify the investment cost for the acquisition of additional equipment for a single well only. The wells, located in a karst vrtača close to an estavelle near Tomislavgrad, with a diameter of 500 mm and approximately 80 m deep, have been accomplished with a low rate of penetration using the conventional Cable tool and resp. Rotary Drilling Method. In this paper results of analyses for the given circumstances are shown: both the efficiency and cost of the mentioned drilling methods performed by the crews of »Geotehnika d.d.« Zagreb, as well as the justifiability of investments in new equipment are evaluated.
