Abstract	This paper presents the development of bottom-hole assembly (BHA) analysis models using simplified mathematical equations. The predictions of BHA bending moment and directional drilling performance of the RotarySteerable Systems (RSS) have been examined with extensive field test data taken in a controlled and non-commercial environment, allowing single step changes in both drill bit features and Rotary Steerable configurations. The testing is unique in that the specific RSS works in field-configurable push-the-bit and point-the-bit modes. Between two distinct RSS operation modes, consistency in stiffness, weight, force applying capability, and control systems leads to a direct comparison of different BHA models. A unique sensor system, integrated into the specific RSS, provided real-time measurement of near-bit borehole caliper and near-bit stick-slip and vibration 1,2 . This feature allowed real-time evaluation of bit/BHA stability and borehole quality. After each test run, memory data was retrieved and used for more detailed assessment of bit/BHA performance. BHA configuration tests were systematically structured in a controlled environment so that the relationship between BHA analysis models and actual BHA behavior could be identified. As a result, the systematic testing and verification lead to the conclusion that the BHA models can be used to effectively optimize Rotary Steerable BHA in both push-thebit and point-the-bit configurations.
