On some of the technology, you have to realize we are starting above ground and trying to put a wellbore in place in a spatial situation that is desired by the oil and gas company. We start with an initial surface survey. We have a bottomhole survey as well. We do some engineering around exactly the placement of that wellbore. We then use a guidance system called a measurements-while-drilling system, which essentially tells us various parameters as we drill the wellbore, and as we drill that down, we're computer-simulating exactly where we are in a 3-D formation.
We also receive different levels of information from that particular tool. It gives us various logging spots. As we drill down, we're trying to match the formations that were designed and picked out through seismic. We're matching those exactly to what we're actually seeing as we drill down.
With regard to the tools we have, we're starting to develop things that have significant computing horsepower so we can try to determine exactly what the bit is doing and where it's heading, so as we drill that wellbore down, we end up landing in the horizon they are looking at. Then we take the logging data we are picking up through real-time information and steer the wellbore across the formation in the desired path and in through the most economic part of the reservoir that we can get into.
