I left SLB few months ago , and during my stay there I was exposed to most of their MWD tools. I worked both in the maintenance and field engineering organization. Please note that all MWD(D&M) tools are expected to withstand 150 degC however some high temperature tools could get up to 170 degC. But this is just industry standard (Baker, Halliburton, and others have such).Their electronics technology has been around for decades, however SLB started off(recently) making incremental improvement and at same time incorporating new technologies. Please don't use the word "see" because there is nothing radical here or new. MWD tools are just sensors.. magnetometers, accelerators, strain gauges , FPGA and some basic electronics power system. In some cases you may have transmitters and receivers oriented to a particular frequency range. MWD tools have sensors in the same family as what we have in a smart phone.
- Cyph0n 11y agoHow 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!
