abstract = "Sand production is complex problem that requires solution before the production at field planning stage. It is important to solve it by careful sand problems and affecting factors analysis with subsequent comparison of sand control methods to choose the best option for implementation. In this thesis, we describe the guideline for Frac Pack design based on completion experience on Astokh Field. We use logging and core data analysis in order to prove the necessity of sand control methods with accurate attention to XXI-layer as previously detected sand production target. Then we describe compound procedure consisting of perforation, proppant, screen and fracturing fluid recommendations. The main part of this thesis involves Astokh field completions description, its results and possible underperformance reasons. By the example of the most representative case, we made surface and downhole equipment review including frac pack treatment procedure with respective pre- and post-jobs necessary for its implementation. Based on this review the subsequent workflow was created. Finally, economical evaluation was done to find out if frac pack completion was successful or not. The proposed methodology in this thesis can be used in future completions on Astokh field or other fields with analogous characteristics.",
