"The well placement technology has advanced to a stage where we can explore small tolerance targets such as thin reservoirs. Well placement with geosteering, which is the real time adjustment of the well path based on the geological responses to place and maintain the well within the best part of the reservoir, is the technology that has made this progress possible. Geosteering however can get very complex with the increasing heterogeneities of the formations and there is no fixed methodology to devise a steering strategy in such complex geological settings. To accommodate this challenge, we investigated three methods to verify their applicability to geosteering. First method was to create a generalized decision matrix which serves as a guideline to select the right tool for a particular well placement challenge. The decision matrix was devised keeping in mind the applications as well as the limitations of each tool with scope limited essentially to well placement. Second method was to analyze the mechanical properties like Mechanical specific energy & Uniaxial compressive strength for their foot printing ability. Third method includes statistical methods like Hierarchal Clustering and Classification tree to identify distinct signatures which could help us differentiate between the reservoir and non-reservoir and hence place the well optimally. All the three methods were applied to the field data from the field of study in Norwegian North Sea and the results indicate that the methods can assist in devising a steering strategy for a highly heterogeneous field with limited uncertainties"--Abstract, page iii.
