Thank you, Mark. Moving to Slide 5, you'll see a snapshot of Stingray pressure pumping. Over the past 2 years, we've worked hard to improve our processes and efficiencies, and it's starting to show. We were able to average 6.25 stages per spread per day in 2016. This is up over 100% from 2014 when we pumped an average of 3 stages per day. While this is an impressive start on its own, we're not -- neither satisfied nor -- we are now routinely pumping 7 to 10 stages per day per fleet. This is particularly strong when considering the intense fracs getting completed.
While it would be easy to say that increases in productivity were all due to our processes, the customer we work for matters as well. Gulfport has been a great customer over the past 4 years, and the processes they have in place allow us to perform at a high level. Throughout 2016, we averaged 6.85 stages per day on Gulfport pads, with 3 recent pads pumped for Gulfport averaging more than 9 stages per day. We look forward to continuing this relationship in years to come.
Our pressure pumping fleet is expected to nearly double over the coming months through the acquisitions of an additional 132,500 horsepower to 6 high-pressure fleets, greatly expanding our exposure to the spot market.
We're pleased with our purchase price, acquiring this horsepower for under $500 per horsepower for brand new equipment. We've begun receiving the initial pumps ordered in November of '16, with those 2 fleets expected to go to work in the SCOOP/STACK during the second half of '17 based on strong customer interest. Given the job we've done for Gulfport in the Northeast, we expect that we will have the opportunity to do some work for them in the SCOOP in the future. We have not determined where our recently ordered 57,500 horsepower will be deployed as of today, instead we will wait to see which area has the strongest demand, once that equipment is ready to be deployed.
As you can see in the lower-right graph, we expect to grow our pressure pumping fleet to nearly 300,000 horsepower organically in 2017 based on outstanding equipment orders, with further expansion in 2018 and 2019 possible as long as the demand continues. We believe we have the management team and processes in place to maintain our current pace of efficiencies, even as we expand into the SCOOP/STACK, and we'll seek to continually improve as we move forward.
Moving to Slide 6. The market for sand has improved faster than we could have imagined, with strong demand starting to impact pricing. As you can see from the charts on the lower portion of the page, we delivered just over 195,000 tons of sand during the fourth quarter of 2016 through Muskie, of which 43% was sold to Gulfport. This was a company record.
The average sales price for the sand sold during the fourth quarter was $27.80 per ton, up roughly 30% quarter-over-quarter from $19.62 in the third quarter of 2016. We're able to generate adjusted EBITDA of $1.5 million during Q4 in our natural sand proppant services segment brokering sand and utilizing our logistics network. Due to increased demand for sand and rising prices, we recently restarted our Muskie processing facility, and initial deliveries were made earlier this week. We intend to ramp up the production at the Muskie facility over the coming months, with full utilization of approximately 58,300 tons per month expected in April.
The demand for 40/70 remains high, with all of our capacities currently sold out. The tightness in the 40/70 market is driving the demand for lesser grades, such as 30/50, 100 mesh and 20/40.
On the pricing side, we're seeing pricing for 40/70 in some areas in the low-30s per ton which reflects spot market trades for 40/70 over $40 per ton. When you compare this with spot market prices experienced this past December, the market has nearly doubled in approximately 2 months.
From an industry perspective, we believe the improving price for sand will lead to the restart of several current -- currently idle mines, increasing supply in the short-to-medium terms. In the longer term, we believe that the fundamental shift in E&P activity to longer laterals, shorter stage spacing and higher sand concentricity will allow the sand market to grow significantly in the coming years. IHS suggests that the industry could eclipse the 2014 highs of 121 billion pounds as early as 2019, with several other firms suggesting this may occur even sooner depending on the rig count.
Increasing sand market will drive the need for logistics. As you can see in the upper-right graph, we estimate the need for 300 to 400 sand trucks per well by 2018, assuming conservative increases in sand concentrations from 2016 levels. We currently have 22 sand hauling trucks, with an additional 40 trucks expected to be added to our fleets in the coming months to ensure we have last-mile solutions in place to support the needs of our customers in all of our operating areas.
Moving on to our contract drilling business on Slide 7. We ended 2016 with 5 rigs operating up from 4 in August, with the average day rate increasing to just under $14,000 per day. This improvement in our average day rate drove positive adjusted EBITDA of $700,000 in our contract land and directional drilling services segment in the fourth quarter of '16, which is up from an adjusted EBITDA loss of $1.1 million in Q3, and bodes well for this segment going forward.
We currently have 4 rigs operating, with another 2 rigs being upgraded to include 7,500 psi of mud systems and walking systems to make them more competitive in today's market. We expect these rigs to return to work during the second quarter to spot market rates and the current spot market rate for our rigs is approximately $15,500 per day.
We are fielding inbound calls for our 4 vertical rigs to drill saltwater disposal wells. Once demand shows several months of work and we have a clear path, we will reactivate at least one of these rigs, but we are not ready to do so at this time.
Our rig moving business continues to see strong demand from third parties, with that segment having its best month ever in December. We expect the rig moving business to remain strong as the rig count in the Permian continues to grow.
Finally, if you turn to Slide 8, let me provide a summation. 2016 was a great year for Mammoth, but we see a significant improvement in both demand for our services and pricing as we look to 2017. I'm proud of what our team has accomplished throughout the year. We now routinely pump more than 6 stages per day per fleet, with several pads averaging more than 9 stages per day.
With the recent rapid increases in sand demand and pricing, we restarted our Muskie facility, which has already begun selling sand during February, and is expected to reach full utilization of approximately 58,000 tons per month by April.
Given that the rig count continues to rise, we expect strong demand for sand throughout 2017 and beyond. Our rig business has seen increased demand from both our existing customers and others, and we are in the process of upgrading 2 of our rigs to be more competitive in today's market. We expect to deploy these rigs in the second quarter. Our coil tubing, the flowback services, while still challenged, are seeing increase in demand or providing a customer base which -- with which to cross sell our other services.
Mammoth is positioned to provide our customers with an integrated solution from mine to well hit. We remain committed to providing our customers with a quality product at fair prices, while growing our business in the areas we think will be the highest demand over the coming years. We believe that the demand for pressure pumping, sand and logistics services will continue to grow over the coming months, and we will be prepared in all 3 areas to meet our customer demand.
The stabilization of oil prices has given E&P companies the confidence to purchase more than $30 billion-worth of new acreages over the last 14 months. With the acreage now in their respective portfolios, we're seeing the effect of these purchases show up in the domestic rig count, which has been a -- which has seen a step change since the beginning of the year, up 14%. This increase in drilling is driving significant demand for pressure pumping, proppant and logistics; 3 areas where we are well positioned to capitalize on that growth. If the rig count projections come true, all 3 of our core business: pressure pumping, sand and logistics are expected to see strong demand. And we will be positioned to provide our customers an integrated approach to complete their wells.
While the energy industry will always be governed by commodity prices, which have historically been volatile, we are confident that the inflection point in the current cycle for the United States service industry occurred during the third quarter 2016.
Mammoth is well positioned in the areas we expect to see the greatest demand: pressure pumping, sand and logistics. And the delivery of our fourth, fifth and sixth pressure pumping fleets later this year should position us to meet customer demand and allow us to put them to work in an improving pricing environment at strong margins.
This concludes our prepared remarks. Thank you for your time and attention. We will now open the call for questions.
