High-Speed Data Transfer Over ... Mud 148

Posted by timothy from the for-the-filthiest-dirtiest-data dept.
An anonymous reader writes "You might have laid Ethernet through some pretty aggressive environments, but how about through a 4-inch diameter steel pipe immersed in electrically conductive mud at pressures up to 1000 atmospheres, temperatures up to 150 deg C, and with vibrational accelerations of hundreds of g? The Department of Energy has announced the invention of a system to allow data transmission up to 1 Mbit/s along drillpipe. That might not sound too fast, but the current technology uses some pretty neat electromechanical engineering to get ... 10 bits per second (on a good day). This will revolutionize the oil industry's ability to see where its wells are going and steer them into pockets of oil."

      Why do you need 1 MB/s for a big honking DRILL?

      Well, for starters you could put an array of accoustic, microwave, or electrical transmitters & sensors in the pipe just BEHIND the drill and image the region ahead of the drill with radar and/or sonar. If you see a pocket of something that sounds/conducts/reflects like oil a bit off to one side, you can adjust the drill to curve in that direction (or send the NEXT one over that way).

      10 BPS just doesn't cut it for uploading imaging information, even if you put most of the fancy processing down with the sensore. But T1 rates are just fine.

      There's lots of other stuff you want to monitor - temperature, pressure, conductivity, etc. to find out what sort of stuff you're drilling through.

      And it's important to know when to give up, stop pouring money down THIS hole and start over somewhere else. It costs a LOT to run the rig long enough to drill even another foot...

      I recall, back in the early days, a company in Ann Arbor made a little board with a CMOS Z80-clone, a ROM with a BASIC interpreter, a serial port, and a few I/O ports - including some analog inputs. They sold a LOT of 'em to an oil company.

      Seems that every now and then they would pull up the drill and send one of these down to measure some stuff. Then they would send the drill down behind it and grind it up. It was cheaper to buy a new one (and the associated cable) each time than to leave the rig idle long enough to pull the old one up. (And considering how fast a winch can crank, and how much custom computer stuff cost back in those days, that will tell you a lot about the per-minute cost of an oil rig and drilling team.)

      So imagine how much they can save if they don't need to pull the DRILL up - disassembling it as they go - then reverse the whole process to put it back down, every time they want to take another reading.

    data transfer over mud isn't new. The best oilfield services companies have been doing it for quite some time.

    As for why they need to get data out, consider that when you're looking for oil, you need to figure out what the EXACT geological formations look like (in 3 dimensions) a mile or 2 underneath the surface of the earth. The more data you can get out of a hole about any number of factors (rock hardness, resistivity, etc...) at a known depth, the better your odds are of figuring out what's down there in the main.
    • What makes this article news is the sudden jump in bandwidth over the current technology: from 10bps to 1Mbps. That's a 100x increase, which sounds pretty interesting to me.

    The key to the new system is a unique non-contacting coupler embedded in connections between 30-foot long sections of drill pipe. The coupler permits data to be sent across the connection and on through a high-speed cable attached to the inner pipe wall.

    For more than 60 years, engineers have struggled with the problem of a drill pipe connection, or "tool joint," that would stand up to the wear and tear of increasingly hostile downhole drilling conditions, yet provide reliable electrical connections every 30 feet over thousands of feet of pipe penetrating deep into some of nature's harshest environments. [...]

    But the excruciatingly slow pace of mud pulse telemetry - 3 to 10 bits per second - often meant that data resolution was so poor that the driller could not make crucial decisions in real time. Often, time-consuming operations would be required to retrieve the downhole data or drilling would have to stop while other procedures were employed to confirm the low-resolution data pulsed to the surface.

    And there is this link, complete with pretty graphics, from the company that actually developed the technology

      That's right, and any oil pumped through it must have the source code for the drill software. Any gas produced from teh oil must then contain the code for the oil and the drill. The gas that's produced can only be run in non proprietary engines and the owner of the engine can request the source for the drill at any time.

    Check out Schlumberger www.slb.com. They're the 800 lb gorilla of the oilfield services industry. Their original solution to finding what was going on at the other end of a drilling rig was to simply pulse mud. Switch it on and off and measure the changes in this signal on the end of the drilling rig. When drilling a rig mud is used to stabilize the walls of the shaft . The advantage of this technique is this... No circular conductor built into the pipe means it can be adapted easily to old equipment and its cheaper. This new system described will eventually make its gains... but its gonna be a while... I saw someone mention wireless... Totally unfriendly environment and there is WAY to much noise, not to mention these holes are so deep you're not going to penetrate all the way back up the hole to the rig on the surface. Anyway... that's a really basic description of what the old new and a couple considerations are in the industry... Look up Schlumberger for a little more info... or Halliburton...

      • No, the Gulf War was fought to keep the prices low. If Saddam had invaded Saudi Arabia, then oil could have hit $100 per barrel. And that means world economic depression, 1930's style not recession. The US and world economy is dependent on foreign oil sources (regardless of the comparative US/Venezuela/Canda import export figures), high oil prices=economic implosion.

        Stating that the war was fought to keep prices high is so incredibly obtuse, I can't even begin to figure out where you're coming from with that statement unless its a paranoid deduction that Bush made money on oil=Bush must wage war to keep oil prices high.

  • As I was waiting for the link to load, I was guessing how this might be accomplished.....Pretty cool solution to this problem. The non-contact electrical connection was the most innovative thing about this. Looks like it uses an inductive ring at either end of the pipe to pass the signal.

    With a little rework, existing pipes could be make to be "intelligent" like this too. You could, for instance, drop a small inductive "washer" at each of the joints and drop the cable in through the pipe. You'd only need to drill a small hole at each end of the pipe to make the connection between the washer and cable inside. I know that this is over-simplifying the situation, but my guess is that existing pipes could be reworked for perhaps $200 per segment in quantity.

    I'm probably one of the few people who find this interesting since I was working on such devices as a software engineer up to 3 years ago. I think we were doing 1-2bits per second mud pulsing and 7-10bits per second with EMF pulsing (this is in the field). You know... the kind of place where the tools still use 8051's because you can get military grade components and need to operate at 175degC. I wonder what kind of bandwidth they get at what depths.

    Kind of interesting when you are dealing with trying to decode data where you get 10-50psi pulses (maybe lasting around .5 seconds) but your baseline can change 300psi a second. Anyways, it was a fun project.

    Directional and horizontal drilling have been in development for the better part of 20 years. This will be a godsend to them. As it is, the equipment required to transfer control and status data back and forth to the motors is bulky, expensive, and prone to failure.

    Most of you don't realize it, but this type of drilling is used all over the place now for all kinds of things. The largest use other than the oil industry is for drilling underneath things (anything, roads, buildings, ship channels, etc) so that cabling, or really damn near anything requiring a hole in the ground can be laid without destruction to the overlying structure. In the early 90's, my dad participated in a project to raise a half-sunken ship from the bottom of a Danish port. They drilled horizontally under the ground beneath the ship, and ran metal cabling underneath it. The cabling was attached to barges on either side of the ship. They pulled apart and raised it off the ocean floor.
  • for the people working at the sharp end of the oil business, this is great news. We routinely lower tools on more or less standard (far from it) cables to "log" the entire hole, and more importantly the oil/gas reservoir section. This ability to send broader band data should be able to free up a lot of costly time when we start running imaging tools that give us a detailed image of the rock formation properties, allowing us to produce more oil & gas from a single well - thus allowing all you ex-colonials to run your overheating processors and your gaz guzzlers (me I have 3 pairs of roller blades - how many wheels ??) ;-)
    Current downhole technology (LWD - logging while drilling - allows us to see directional information, formeation resisitivity - a function of porosity and pore fluid properties - ie oil & gas not conductive - brine conductive, we routinely use Gamma ray radioactivity for correlation purposes - stratigraphy, and when the drillers let us we run nuclear tools that read directly formation density and porosity - of course these numbers are messed up by the thing (hydrocarbons) we are looking for - lots of computers required to sort out the nuances. Newer technology is allowing us to see Array sonic (like seismic data), CMR technology - a great way to see fluid properties. With all this band width we would be able to evaluate a hole sooner, better (less drilling fluid invasion into the reservoir), and improve reservoir and field development starting from the exploration wells, something that many companies are trying to do right now, as expenses for drilling in hostile environments can be huge - just go and hire a deepwater semi-submersible drilling rig for a month or two, then add all the other essential services for finding and producing the black stuff. As time goes on, it just gets more expensive and more challenging to find - and also a lot more interesting, thats why I love my job! - well mostly :)

    Largely because of the stumbling block, in the mid 1970s developers turned to a technology called "mud pulse telemetry." Mud pulse telemetry foregoes electrical connections and transmits data as pressure pulses through fluid circulated to clean the cuttings out of the wellbore.

I am thinking though that at some deep water drilling, which is generally say 5 times the cost our operations are, and normally just doing Exploration ahead of guys like us, getting some real time data while drilling to read Reservoir Data would be a boon.
