How about density, porosity, resistivity, and so on? I saw some LWD tools that used different sonic-based techniques, nuclear sources, and others for formation evaluation. I'm thinking of the PeriScope, EcoScope from LWD, and the TeleScope from MWD. The point-the-bit tech in the Xceed is also amazing!
I didn't get to read up on the details, as they prevented interns from accessing technical documents, but from what I saw some of the sensors were quite advanced. Granted, I don't have that much exposure to state of the art sensor tech, so I could be wrong.
- ejanus 11y agoI wont like to discuss SLB technology here because that is the duty of their salesmen, however I will pick on "point-the-bit tech in the Xceed" technology to illustrate a bit. Xceed is modeled after an MWD tool called PowerPulse(TeleScope predecessor), it copied about 90% of that technology. However to the uninitiated it may look like something from the outer space. It has resolver(motor), that means you have angular position, and throw in magnetometers, accelerators , and sensors into the play. Presto!
