| Abstract: | Data on all drilled wells were analyzed for comparison of the effect of different bit types, weight on bit, and rotary speeds on the penetration rate in the various formations and depth intervals. This was initiated in an attempt to improve penetration rates and reduce per well drilling times. Based on this study, an optimum bit selection, bit weight and rotary speed program was incorporated into drilling plans for subsequent wells drilled in the area. Initiation of this study resulted in significant improvement in penetration rates, in spite of the fact that some adverse conditions existed, such as formations, which have been pressure depleted by production, and drilling of high angle holes. |
