Sinking and well completion by drilling
{"Image DocumentName": "Sinking and well completion by drilling", "Image ImageDescription": "Nowadays the main priority of the innovative activities of the enterprise consists in lateral drilling and side-tracking. In 2008 there were two wells drilled with lateral tunnels of 300 m and 900 m total length of the open hole. The results of hole drilling proved high efficiency of the given technology. At the moment the company continues longhole drilling by the well completion method. Having acquired considerable experience in longhole drilling with different length of the lateral part, ZAO Samotlorneftepromkhim has become an attractive service company for the customers. The given approach is highly efficient both from the viewpoint of oil recovery and financial efficiency. In the period of the company bought and brought into operation four MBU -125 drilling rigs and two MBU-140 drilling rigs with a four stage cleanup system for drilling well up to 3500m, well upgrade by sidetracking method and well deepening using the bottom of the completion string. The advantages of the given rigs are definitely the possibility to drill from the multiple well platform in case of sufficient land allocation. This method eliminates the dependence on the matrix (main)well hole and reduces to maximum the expenses on constructing other multiple well platforms. However, maximum reserve recovery in the remaining oil pay zones full-gage infill drilling. At the moment the company employs 6 crews of side-tracking, namely four on Samotlor field and one crew of mobile in-field drilling on theTarasov field. 8.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
