METHODS AND SYSTEMS FOR DESIGNING AND/OR SELECTING DRILLING EQUIPMENT USING PREDICTIONS OF ROTARY DRILL BIT WALK

摘要

Methods and systems may be provided simulating forming a wide variety ofdirectional wellbores including wellbores with variable tilt rates and/orrelatively constant tilt rates. The methods and systems may also be used tosimulate forming a wellbore in subterranean formations having a combination ofsoft, medium and hard formation materials, multiple layers of formationmaterials and relatively hard stringers disposed throughout one or more layersof formation material. Values of bit walk rate from such simulations may beused to design and/or select drilling equipment for use in forming adirectional wellbore.
