Wells Integrity

I found your name at the website www.wellintegrity.net and I find some of the contents quite informative and useful.  I work as a Wells Integrity engineer in UK and is looking at a project to determine casing wall thickness (surface casing, conductor casing, intermediate casing) and remedial method to alleviate sustained casing pressure (SCP) in annulus.

So far I came across only one techniques to measure casing wall thickness and that is using pulsed eddy current (PEC).  However the existing method is only for annulus without pressure.  Are you aware of any other methods available and if yes, can the method be used in pressured annulus.

For remediation, I am only aware of VetcoGray casing annulus remediation (CAR) method to alleviate SCP besides lubricate/bleed.  The equipment can work in reasonable annulus pressure (250 psi).  Once again are you aware of any others in the market?

P.S.:     By the way, can you tell me what is the intent of your website?  I don’t see a forum whereby interested well integrity engineer can trade/share information.  Is there plan for one?
