Exploration drilling earned the moniker "wildcat drilling" for two reasons: Often the only living creatures encountered by drillers would be wild cats and more often than not drillers didn't encounter much oil either. Today's oil industry, however, is much different, with the wildcat days of yesteryear long gone. It has been replaced with new drilling technology that makes it easier not just for explorers to find oil, but to tap the sweetest spot of the reservoir. On the bleeding edge of tech meets oil patch is Halliburton (NYSE:HAL), which is finding technology to be the key to unlocking the most oil for a producer's money.

Using technology to find the best spots
This was something company President Jeff Miller detailed on the company's most recent conference call. He said:

Improving a customer's cost per barrel of oil equivalent is core to our value proposition. This is why we continue to invest in technology, and our emphasis is two basic tenents. One is increasing reliability, eliminating moving parts, simplifying designs, and helping eliminate nonproductive time at the well site. The second is making better wells. Products like AccessFrac, CoreVault, and DecisionSpace help customers identify, and access the sweet spots of their reservoirs. And more importantly, these products are seeing increased uptake during this downturn.

Miller notes that the company is attacking technology in two ways. First, it is investing in technology to improve the mechanical reliability of equipment, which will lower costs for producers because they won't have to waste time and money changing parts or fixing broken equipment. However, what's even more compelling is its investments to make better wells, which it is doing by enabling drillers to, in a sense, see deep within the earth so that they can drill wells into right into the best part of the reservoir target.

A real world example
Well targeting, in particular, has helped producers such as EOG Resources (NYSE:EOG) to drill better wells during the downturn, thus earnings stronger drilling returns. EOG Resources uses this innovation to put together a heat map to identify its best horizontal targets before it starts drilling.

Instead of just drilling and hoping to find any oil, EOG Resources follows its map and drills to the exact depth where it expects to encounter the sweetest spots of hydrocarbon bearing rocks. By tapping the best spot, it can pull out more oil and gas per well, thus enabling it to vastly improve its drilling returns. In fact, when combined with service cost reductions and other innovations such as using more sand per well, EOG Resources' drilling returns are as good as, if not better, than the returns it was earning when oil was closer to triple digits.

Halliburton: The oil-field technology company
Because drillers are finding so much success when employing technology to drill better wells, it's driving strong growth for Halliburton's technology offerings. Miller noted on the call that, "Adoption of DecisionSpace is up double digits from 2014, for example. And the usage of AccessFrac has grown more than 60% over the last year." That's helping to buoy the company's margins during the downturn, offsetting some of the weakness it's experiencing in its other products and services.

In addition to that, it's really setting Halliburton up to be the oil-field service company of choice because it has the tools to help oil companies drill better wells. That will not only suit the company nicely during the downturn because it will receive a steady diet of work, but it really positions the company to capture the bulk of the new work when conditions improve.
