... considered as well. Geomechanical modeling allows you to minimize risks during the drilling process, considering the properties of rocks, by improving technological features of drilling process as well as helps to optimize the existing field exploration plan. This abstract presents the results...

... environmental variations throughout the drilling process. The results of this new area of research could change the way future horizontal wells are planned. Implementation of this algorithm can be applied in a multitude of ways; incorporating it as an artificial intelligence module in an existing drilling...

...) and high temperature (250ºC) conditions. The UDS is equipped with a single cutter, a method to rotate the rock against the cutter, and a three-force-component load cell. The system incorporates a view window into the pressure vessel to allow both visual and X-ray examination of the drilling process...

... ABSTRACT: The drilling process monitoring (DPM) has been used in site characterization. Information from the drilling monitoring can be added to the existing geological information for more accurate identification of the rock discontinuities and weathered degrees of soils and rocks, because...

... ABSTRACT: This paper presents a case study on characterization of cavities in marble in karst terrain. A recently developed insitu technique, namely Drilling Process Monitoring (DPM) is applied in the cavity characterization. This technique is able to characterize the mechanical strength...

... model is presented in this paper to simulate the percussion drilling process. The numerical simulation for rock failure is based on a Mohr-Coulomb model with strain-softening behavior, Rayleigh damping to dissipate excessive oscillation energy, and a fatigue/damage algorithm to update rock properties...

...) topics which seem to be relevant to the process, we have knowledge of the drilling process in both qualitative and quantitative terms from observation of the actual process, and we have certain modeling procedures, by which we bridge the gap between these two previous areas. The usefulness...
