Today's Trends: BOP, Wellhead Ratings Favor Surface-Based Applications

Oilfield customers expressed greater satisfaction for surface-based blowout preventers (BOPs), wellheads and trees versus subsea applications, according to oilfield customers surveyed by EnergyPoint Research.

Data gathered indicates that customers see subsea blowout preventers, risers and flexjoints, and wellheads and trees as particularly lacking, followed by umbilicals, controls, manifolds and flowlines. Remotely operated vehicles (ROVs) received the highest long-term ratings of any subsea product category that EnergyPoint tracks.

"The issue with subsea equipment is particularly noteworthy in light of the fact that, in the eyes of our survey respondents (i.e., drilling, completion and production engineers, managers, supervisors, etc. in the industry), deepwater/offshore service (as opposed to product) suppliers are some of the most highly regarded in the industry. This is especially the case when it comes to safety and environmental matters," EnergyPoint noted in its second quarter 2010 Customer Satisfaction update.

While the large gap between ratings for surface-based BOPs and those for subsea BOPs is particularly noteworthy, GE-Hydril rates first in subsea BOPS. Dril-Quip and "its no-nonsense style and focused product-line" made the biggest splash with survey respondents for wellheads and trees.

Probably we shall see more development for the use of surface BOPs for floating drilling units. Subsea BOPs controls will be improved as well as additional disconnects allowing floating rigs to automatically and quickly move off location in the event of a blowout.

Having worked in the industry for 10 years I have installed surface equipment like landing rings, csg hangers, wellheads csg spools, packoffs, tubing hangers, and trees for companies like Enron,Cairn Energy,British Gas, Conoco Philips, StatOil, ONGC, GSPC, and many other companies and have always had success in testing the same. The surface wellhead equipment is really reliable and very efficient. If any company needs more information regarding this please be free to contact me.
