dc.description.abstractUnlike the conventional well technology, slim hole uses a relatively narrower well size. The concept has been introduced long, but the application in petroleum well not very common. Based on its advantage in terms of cost, there is a possibility to use it for petroleum well and geothermal wells. This thesis evaluates the slim hole drilling method with the objective of investigating how far one can drill. For this, the thesis work considers three qualification operational conditions. These are drill string mechanics (Torque, drag & Stress in drill string), hydraulics and cutting transport efficiency. The method of analysis flow chart is presented in section § 6.2. Using this method, two slim well structures obtained from Kuwait, and Carter Creek Field were analyzed. In addition, an ultra-deep slim-hole scenario also designed and analyzed. Based on the evaluation of considered designs, the feasible slim well design presented in three categories: • Shallow-slim well (up to 13000ft) can be drilled with low grade E-75 • Deep-slim well (16000 ft) can be drilling with a combination of (E-75 and G-95) Grades • Ultra-deep slim well: (20000 ft) can be drillied with high grade, S-135.
