Paper presented at the IADC/SPE Asia Pacific Drilling Technology Conference, August 22–24, 2016
Paper Number: SPE-180530-MS
... One important element enabling the pro-active management of BHA integrity is the ability to model a BHA design during planning stage to ensure the expected drilling loads are not exceeding equipment specification which can lead to or increase the risk of failure downhole. Hence, mathematical...

Paper Number: SPE-128203-MS
... a larger hole below a smaller drift diameter requires slightly different BHA configurations to maintain consistent directional control. There are currently no published reference tables or programs to accurately predict the directional behavior of bicenter-bit bottom-hole assemblies (BHAs). This paper...

Paper presented at the SPE/IADC Middle East Drilling and Technology Conference, October 22–24, 2007
Paper Number: SPE-106935-MS
... Abstract This paper presents the development of a new bottomhole assembly (BHA) program and how it is used to deliver optimal BHA design. The new program allows users to run static and dynamic models in the same application which will save time and minimize errors. For the static model...

Paper Number: SPE-210340-MS
... Abstract Bottom Hole Assembly (BHA) reliability is critical to deliver wells on-time and within budget. Improving reliability is a combined effort between operators and service providers. In the D.J. Basin, well drilling times are between 48-60hours. A 10-hour trip for failure can account...

...Abstract Abstract Designing robust hole-opening BHA to drill two consecutive sections with interbedded formation in a deep HPHT appraisal well is exceptionally challenging. The two hole-opening sections, 17in × 20in and 14-3/4in × 17in need to retain strict verticality requirement and the final...

... The Torsional Vibration Isolation Tool (TVI) is an anti-vibration tool that protects sensitive BHA components from damage due to HFTO. It contains a slender shaft acting as a torsionally weak spring. The slender shaft reflects torsional waves trying to travel through the TVI. Therefore, torsional...
