    Abstract

    Improvement of the drilling methods and well productivity have been focused on underground energy harvesting for decades. Radial Jet Drilling (RJD) has been brought to attention, as it requires small volume of water, reduces risk, and expenses, which make this technique more lucrative. RJD is done by hydraulic jetting through the well to make lateral wells with a smaller diameter. RJD can be, therefore, considered as a potential technique to boost the efficiency of the wells (E. Peters et al., 2015). However, according to its complex interaction with the main well, the robust numerical model is required to predict its performance. This research aims to investigate the sensitivity of selected parameters such as length, angle, and location of RJD on one of Danish North Sea. A commercial reservoir simulator based on finite difference method is used to analyze the sensitivity. Thus, the modelling can provide valuable data concerning effectiveness, location, optimum length and number of lateral wells. Based on this data the optimize RJD model on the field can be achieved which lead to increasing in recovery factor
    and optimized operation.
