Thanks, Glen. During the third quarter, we ran 19 rigs in the Appalachian Basin. And we also ran an average of 4 frac spreads, so -- on the frac-ing side. They drilled and completed 44 wells. This firmly equated us as the most asset operator in the Marcellus, as we have the highest growth trajectory with a triple-digit continuous annual growth rate for the last 4 years. We've been at the last strategy is to pursue this rapid pace of development, and the answers is pretty simple. If we're generating the types of returns that the Appalachian Basin, of course, I'm talking about Marcellus and Utica, we're getting the types of returns that this yields, and we want to bring that value forward.
Our rates of return at Marcellus range about 40% in the rich gas area to 90% in the highly rich condensate area. These rates of return do not factor in the SSL completions, and those appear to enhance these returns by approximately 15% to 25%, as Glen mentioned. In the Utica shale, we believe our rates of return range from approximately 100% in the rich gas area to over 200% in the highly rich condensate area. Obviously, with these types of returns, we wanted to develop as quickly as possible.
Now, of course, in order to take care of our production and do what we have to do to be able to move what we have to be forward thinking versus we've jumped out, we have secured the rigs, we've secured the frac fleets, and -- but just as importantly, we want to make sure that we can get our product to market at the economic levels that we plan. We've done that not only by the hedge book that Glen has mentioned just now. And those hedges were put in place years earlier, so people wonder how are we reaping these $5 plus prices. We've been hedging the other part of the curve for a number of years, so we continue to hedge the curve as many of you know is in contango, and so by hedging the -- outer part of the curve, which is definitely a part of our strategy, we reap the benefits in future years. And that's what we are reaping today from past hedges.
Not only done the hedge book that Glen mentioned, but also, we committed to process it, to stay out in front, compression facilities, even before the first wells are drilled. And then we put a big emphasis on securing takeaway capacity in order to get our products to the market. We, today, have about 1.3 bcf equivalent per day of firm transport. That'll be all effective in our region by the end of 2014. We continue to build out this firm transport to accommodate the significant growth we see coming in the future.
We've been able to be in this forward thinking mode for a number of years, because we recognized early on and located ourselves in the right geology in our parts of both the Marcellus play and then the Utica play. And we have built our acreage positions in both plays, in the most prolific liquids areas. The Marcellus, our core liquids-rich net acres has increased to 302,000 acres since the last press release. That firmly positions Antero with the second-highest exposure to core Marcellus and also to Utica amongst our peers.
In the Marcellus, we continued to be the most active operator, with 15 rigs working for us, 2 dedicated frac spreads. We continue to drill the longest laterals in the play. We average 7,100 foot lateral lengths or our 34 wells completed in this last quarter. We're able to drill these long laterals, of course, due to our concentrated acreage position where we have good contiguous leases that we can pull together in the units and drill long laterals. And also a huge benefit for us is the general geology in this portion of West Virginia, no faulting. And that's what we were looking for when we entered the play. We have yet to drill across the fault, and we've drilled more than 250 miles now of lateral feet in our 200-and-some wells of horizontal drilling in the Marcellus. So no faults, and that makes for great economics. Our tight curve in the Marcellus is approximately 1.5 bcf wellhead gas, per thousand feet of lateral. And is supported by approximately 217 wells across the entire breadth of our acreage position. I don't think you ever reach perfection in techniques, so we continue to innovate in the area. We've seen nice progress in the play as we have had improved results during this last quarter as we have extended our application of our shorter stage lengths or SSL completions. We've now decided to use our SSL completions, I'm pretty much all wells going forward, as we're seeing early trends -- I'll emphasize early -- of at least 20% to 30% greater productivity over our tight curve. And we estimate about 20% additional well cost. It's still early days, and time will tell, but so far, looks good. We continue to run 15 rigs into 2014, and we expect the pace of development and growth will continue.
Let me shift to the Utica. We're running 4 rigs in the area, with the fifth one to be -- the fifth rig to be added this month. We've put online 10 wells during the quarter with terrific results. We have 8 of the 9 producers now in the play. We are able to start flowing the wells in early August, but we were limited to 90 million cubic feet equivalent a day as the Seneca plant and processing facility wasn't operational yet. And so we were flowing these wells north up the Cadiz plant in Harrison County. And because of infrastructure limitations, we had to flow these wells against 1,100 pound line pressure up to the Cadiz plant, so that definitely pushes back on the well's performance. But it's really a testament to the tremendous pressure and pressure gradient of the Point Pleasant shale, of course, the main pay in the Utica play that we're able to produce in such an environment.
As we noted in our press release, we've now increased our acreage position to 104,000 net acres in the play, and we're talking about in the southern core, which is the most important part of the Utica. Since the last press release, we've added 1 well in the Utica that tested for over 7,000 barrels a day equivalent, with 44% liquids, assuming ethane recovery. This was the fourth best IP that we've seen in the play, and we look at all reports and now allows Antero to have 8 out of the 9 top producers in the play. And our wells are in the 5,000 to 9,000 barrel a day equivalent range. And those that are not in the core are more like 1,000 to 2,000 barrel equivalent.
We also have 6 wells that are currently being completed and are forecasted to come online in December of this year. And in fact, one of those, we are just testing and starting to bring online today and also looks encouraging as well. We'll be able to accommodate these wells, as the Seneca processing facility -- we just came on -- with the processing facility that just came online. And we've secured the entire capacity of the new, we call it Seneca I, with all of the initial 200 million cubic foot a day equivalent that's available to us. The capacity increases throughout the next year with Seneca II and III, and results in total firm processing capacities that's firm to us, to Antero, of 350 million cubic feet a day by the second quarter of 2014. And we have an option built in that we can increase to a total of 400 million cubic a day by early third quarter of next year. So capacity of 350 million cubic feet a day by second quarter and up to 400 million cubic feet a day by third quarter of processing firm to Antero. Additional processing beyond this timeframe is in the planning and succession stage.
In addition to the processing capacity, we contract with a third-party within compression and condensate stabilization facilities. This will be the first compression within our field and should allow us to flow unconstrained to back pressure that I was talking about through the field and into the line. The first facility, which is 120 million a day equivalent compressor station should be online by the end of November. As I mentioned, we're adding a fifth rig this month to the play, and that's going to further accelerate development of the Utica. And we will continue this pace into 2014, and that will allow for tremendous growth during the year.
Let me talk about the dry Marcellus -- excuse me, the dry Utica real quickly. We do have an additional 116,000 net acres of deep rise [ph] in West Virginia, underlying our Marcellus that has good Utica dry gas potential. We've done the mapping, and it looks quite perspective. There've been some recent encouraging industry wells in this similar dry gas area, along the trend. And so we have identified on our deep-rise [ph] acreage 950 potential drilling location. This again, is on our acreage in West Virginia, and it adds up to about 5 TCF of net resource to Antero. We are going to bill our Utica dry gas well in West Virginia some time in the first half of 2014. So we'll have our own results pretty soon.
So in summary, we're the most active operator in the Marcellus. We'll soon likely be the most active operator combined in Marcellus plus Utica, and we have the highest growth rate in the combined plays. We've been forward thinking and securing the necessary takeaway and infrastructure to allow for accelerated development of this very profitable and prolific asset. We continue to grow our position in both plays, but within the Marcellus, we added some 12,000 acres, acres -- net acres in the third quarter. And we might have -- we're likely to have more than that to close in the fourth quarter. So more than 12,000 acres additional in the fourth quarter. Our assets contain the second-largest liquids exposure, with our acreage being again the core of the core, which is very important for us.
And with that, that concludes my remarks. And operator, we're now ready to take questions.
