COST OPTIMIZATION IN DIRECTIONAL DRILLING VIA SELECT THE SUITABLE AKO, SIZE AND SUITABLE PLACE FOR STABILIZERS
Abstract. One of the process for reducing the cost is reducing the time of drilling.in Directional Drilling is reduce the slide volume and select the appropriate number for AKO on down hole motors is suitable for different dog legs This is in addition to reducing costs, especially in offshore platforms will be correlated take predetermined path and finally, in addition to increasing the speed creates a clean and well maintained angular displacement to be added. We can reach quickly a suitable motor angular rotation of the slide. Since in rotation, increases ROP, we reach our goals faster. On the other hand, by choosing appropriate parameters for drilling and stabilizing the rotation, We maintain our angle without slide. in this article is tried, by selecting angle of the downhole motor suited to the dogleg and choosing Suitable stabilizers and the distance to it due to the size and depth of the wells in the number of reservoirs of the south western Iran is according with the characteristics of Gachsaran, Asmari, Sarvak layers suitable for directional drilling with short radius , medium and long term.
