Regarding the links in my previous post, the system has removed the "www.youtube.com" from where it says link removed. Don't know why it would do that. Others have posted links to the website successfully. I've tried adding exclamation marks this time. Anyone any idea why it's doing this?
Wubert I think Hurricane will be using a Rotary Steerable System which either pushes or points the bit in the required direction. See links to videos.The current maximum build up rates for standard systems are in the range of 6 to 12 deg/100 ft although special application tools are available for higher rates. I don't know what build rates Hur are using though. The profile will vary from well to well depending on the relative surface and target position and depth. Probably below 4 deg/100ft I would imagine. I've also included a link to a basic explanation of mud pulse telemetry which is the method of communication to and from the downhole tools used by the vast majority of the systems today.
