BHAPRO - BHA Mechanics Model

BHAPRO Introduction Video

In the modern oil well drilling industry, a typical Bottom Hole Assembly (BHA) always works in harsh downhole environment and must survive severe mechanical and thermal loads. The complex loading conditions can cause various types of failures such as bit wear, directional control failure, low ROP (rate of penetration), low quality of measurement data and so on. Modern BHA may include expensive equipment such as mud motors, rotary steerable systems (RSS) and M/LWD tools. Extending their service lives and fully achieving their functions are main concerns of successful oil well drilling.

With the number of long horizontal and extended-reach wells increasing, Pegasus Vertex, Inc. (PVI) believes that BHA performance prediction has become a critical process during the planning phase of drilling operations. Therefore, PVI has developed BHAPRO, a software that calculates the stress and BHA components under complex downhole loading conditions. It is able to locate contact points between BHA components and wellbore wall, and also identify critical rotary speed (RPM) to avoid detrimental vibrations. With the aid of BHAPRO, users are able to optimize BHA design, improve BHA performance as well as reducing failure risks.
