This report fundamentally discusses the preliminary research done and the basic understanding of the topic chosen, which is comparison study for stuck pipe detection method, current method and statistical method. Stuck pipe in the drilling industry results in hundreds of millions of dollars wasted because of the extra cost to ftx the problem and the time delay of the operation. The occurrence of stuck pipe consists of drill pipe, casing, tubing and coiled tubing getting stuck downhole. Amongst the reason why the pipe get stuck is because of mud sticking, sand sticking , key seat sticking, stuck packers, crooked pipe and foreign object in hole. Technology at the moment allows detection of stuck pipe through various method and the method which will be compared to the statistical method for this study is where readings from pressure while drilling tools are read in a flow pattern and then with the experience and the knowledge of the engineer, he or she is will determine whether such occurrences will happen or not. The scope of study for this project covers 3 important parts, literature review, data gathering and analysis of data. The study begins with familiarizing with the theory behind the statistical method, followed by case study of previous tested wells. The study then is continued with familiarizing with the current method used and the gathering of data in order to compare the efficiency of the statistical method with the current method. The data obtained then will be use for the statistical method calculation and the results will then be compared with the results given by the current method.
