N2 - In the scope of an ever-changing oil and gas industry and today’s low oil price environment, performance improvement needs focus more than ever. Conventional drilling technology cannot provide the step-change that is needed to overcome the industry’s challenges. The Lightweight Drilling System (LWDS) presents a drilling technique capable of improving the oil and gas industry’s performance and enabling operators to explore and develop resources that cannot be drilled economically by conventional methods. Furthermore it offers a paradigm shift in formation evaluation techniques, giving the operator the opportunity to gather a more comprehensive view of the geology. The system builds on the widely researched basis of slimhole technology and claims to implement the lessons learned from the extensive campaigns in the eighties and nineties. This thesis intends to extend previous and current work at think and vision GmbH and the Chair of Drilling and Completion Engineering by a feasibility study for a Central East European operator in order to show the vast economic, well quality and environmental benefit of the LWDS. Furthermore it explains how the major lessons from previous slimhole campaigns can be overcome today, in order to make the LWDS a viable option for every operator.
