Drilling operations are the most expensive in oil and gas industry. One of the main contests in drilling is about tripping with considering pressure windows. While tripping in and out, there can be rise or fall in bottom hole pressure. It is very important to maintain the pressure value in pressure window. The pressure window is defined by upper limit, fracture pressure and lower limit, pore pressure. In recent years, oil and gas companies have been trying to operate the well operations in a safe and financially effective manner. Obviously, due to the fractures, depletions, and deep waters, well operations become more challenging in terms of safety and finance. This is why, the industry is focused on developing new technologies and techniques in order to boost the efficiency and effectiveness of wells. For many years, it has been so challenging for the industry to deal with the pressure, by considering Non-productive time, safety, and sustainability, as well as protecting well from kick or fracture. So, there was a need for a new innovation that can reduce the risk for the personnel and regulate the tripping speed. One of the latest developments is Data While Tripping technology, which aims to transfer data with even considering the transfer speed. First, it was deployed on 2 offshore rigs in North Sea for final model checking. By development of DWT tool, need for personnel in the red zone was abolished; time savings were also proven. During tripping operations, continuous pressure measurements were supplied via along string measurement tools. To sum up, introduction of the data while tripping device has been a success in the industry for turning the lights on downhole and keeping lights on downhole, which means deploying and utilizing wired drill pipe during tripping operations. Although DWT is new technology in oil and gas industry, it is becoming more well-known in recent years. In 2020, NOV (National Oilwell Varco) spent significant amount of money to produce new DWT device. As it is part of WDP technology, it is mainly in use with wired drill pipe and along string sensors. The new tool was installed in 2 rigs in the North Sea, and the obtained results such as equivalent mud weight and data on surge and swab effects, were really helpful on determining new faster and safer running operations. This report has been designed to give the reader detailed knowledge about Data While Tripping as well as modelling tripping speed by considering achieved pressure ranges. The top priority has been focusing on delivering comprehensive explanations. The major goal is for the reader with little or no prior knowledge of the DWT technology to be able to completely comprehend technical properties of DWT. In the report, the beneficial sides as well as working mechanism of DWT tool are discussed detailly. In that purpose, the author used Python coding in order to show and explain the relationship between pressure and tripping speed. In addition, the factors affecting this relationship are represented in thesis as well. In addition, the ecological aspects as well as case studies have been discussed in the report. It is clear from the results from the field cases, such technology is indispensable in managing tripping speed, therefore non-productive time.Unfortunately, since it is a new technology, it is almost impossible to find real field data to use in the coding. But simulated data has been applied in the Python in order to generate the model. In the report, detailed information regarding coding is given with illustrations of the results.
