Optimization of drilling parameters for extended reach directional wells with an early kick-off point

Abstract

This article analyzes the impact of an actual trajectory of a J-Type directional well with an early kick-off point on the values of torque and drag along the bore hole.The actual data collected while drilling the directional SU-2 well with a target depth of 5000 m (South Urikhtau field) was used for the analysis: trajectory survey data results of the well, actual bottom hole assemblies applied (dimensions, material and characteristics of the elements), the actual drilling mud parameters according the control acts, actual drilling parameters according the daily drilling reports and mud logging curves, etc.Calculations of torque and drag were performed on a specialized software Landmark, a comparative analysis was carried out with the design values of parameters and appropriate recommendations were issued.
