Frack sand companies look more and more like compelling investments in today's oil and gas industry. Not only are they able to tap into the one big positive trend in the industry -- U.S. shale drilling -- but most of these stocks are still reeling from the oil price crash that started close to three years ago. One of the more compelling investments is Hi-Crush Partners (NYSE:HCLP) thanks to its lower cost operations and some interesting growth plans slated to come online in the coming months. 

During the company's most recent conference call, Hi-Crush's management walked investors through some of these growth plans and the trends that underpin those plans. Here is a look at some of the most pertinent management statements from the company's most recent call with investors and analysts.

Sand and sand logistics are becoming the keystone issues for shale development

For the past year, shale drilling in the U.S. has been growing at a rather astounding rate. Oil prices in the $50 a barrel range were more than enough to entice producers out of their capital preservation strategies and back into producing more oil from places like the Permian Basin. According to Hi-Crush CEO Robert Rasmus, this is putting enormous strain on companies that manufacture frack sand as well as the logistics network to deliver it to shale basins.

Bottlenecks and industry disruptions will only continue to negatively impact completion schedules and rapidly inflate E&P input cost. For suppliers that attempt to force the projected volumes through repurpose third-party sites, we believe these disruptions will only worsen. It's safe to say, like production facilities, not all frac sand terminals are created equal. Terminals located directly on Class-1 rail, with enough track space to cycle unit trains and silo storage capacity to offer a mix of grades for numerous customers will be the winners this cycle and over the long term. As an example, today's frac designs can require more than a unit train of sand to be pumped over, roughly, a 10-day period of time. In a perfect world, this sand would be procured through 1 purchase order with 1 sand supplier through 1 nearby location. Unfortunately, in today's markets, many sand suppliers do not have the necessary terminal footprint to support these orders, especially when jobs are delayed or frac designs are adjusted at the last minute. As a result, many jobs end up being sourced from various different transload locations across a spectrum of sand suppliers to ensure that an adequate safety supply of product is available, should logistical disruptions arise. Needless to say, this is not an efficient approach as it requires significant administration and coordination, while at the same time, increasing the risk of both additional fees both for the sand itself and the associated transportation and handling expense.

Of course, Rasmus used this situation to tout the fact that Hi-Crush's Northern White sand facilities all had Class-1 rail loading facilities that enabled it to meet customer demand. 

Last mile logistics matter

Continuing on that sand logistics theme, Rasmus also went into the weeks on last mile logistics. This has been a big challenge for sand suppliers as delivery from rail terminals to well sites have been some of the less efficient aspects of the supply chain. So this gave Rasmus an opportunity to talk about its PropX and PropStream services. These are the last mile services that use interchangeable hoppers instead of dump trucks. So far, it looks like these kinds of services are paying off. 

Based on current projections, PropX systems in use by the end of 2017, whether by Hi-Crush through PropStream or by third parties, are expected to have more than 10% of the market share for delivery of sand to the well site. Given that the first PropX system was in operation just last fall, the market acceptance has been phenomenal.

Hi-Crush isn't the only company seeing this kind of success with last mile services. U.S. Silica Holdings (NYSE:SLCA) mentioned on its conference call that its Sandbox logistics service is growing at a similar breakneck pace. If Hi-Crush and U.S. Silica can continue to find success with this last mile service and improve on-time deliveries, it could give them a differentiating factor over the rest of the frack sand industry.

Look at our new toy

With the Permian Basin quickly becoming the crown jewel of the American oil and gas industry again, frack sand producers are looking at all the ways possible to lower sand costs and get as much product delivered to the basin as possible. One way to do that is with a mine that is in the basin. Hi-Crush recently purchased land in Kermit, TX that has the potential to be a premier sand mine for the company. Here's Rasmus describing what it could do for the business. 

With Kermit's expected favorable production cost and its proximity to Permian demand centers, our in-basin facility should be the lowest delivered cost sand plant in the most active basin in the United States... Once completed in the third quarter, Kermit will represent a nearly 30% increase in our total annual production capacity, giving us an unparalleled Permian footprint. We will be able to sell in-basin sand in addition to serving the basin with our 2 and soon to be 3 owned and/or operated terminals that supply Northern White sand.

It's looking like Hi-Crush made a shrewd move obtaining this land and turning it into a sand mine. It also helps if the company can blend that sand with Northern White sand because it will up the quality of the product. 

Industry could be coming up short

If there is one thing worth critiquing about Hi-Crush's plans, it's that management is working on a short time horizon for all these expansion and development projects. One lesson that we learned from the oil price crash is that over-building for hypothetical growth could be devastating if that growth never materializes. Also, the company is putting off some debt reduction to do these expansion projects. According to CFO Laura Fulton, though, these moves need to happen now because the industry is already undersupplied.

[B]ased on an average sand usage of just over 5,000 tons per well, an environment where the industry is operating 900 rigs or just 5% above the most recent rig count, would result in the need for approximately 95 million tons of sand. We continue to see average sand loadings increase, so we concur with the analysts' forecast and believe the assumption is driving this level of demand at today's intensity levels could even prove to be conservative.

With that expected level of demand or more for 2018, the industry will need to add more capacity to keep up. And even if all the announcements made today happen exactly as planned, it's not out of the question that there would be a shortage when it comes to the right size sand at the right location.

It's entirely possible that this is the case, but a lot can change between now and 2018. We have already seen oil prices drop from the $50-$55 a barrel range to $45 a barrel or lower. If oil prices start trending down again, those ambitious growth plans could look like overestimations much like they did in 2014.

Turning these trends into profits

Despite all of this good news about high demand and short supply of sand, Hi-Crush has yet to post a profit. The company has said that the high costs of starting idle facilities back up and others not working at full capacity impacted margins. So when asked about these margin implications, Fulton broke down how those margins should improve in the coming quarters. 

I think if you start with the $8.15, as we mentioned in our remarks, there's about $2 per ton impact from the winter maintenance, and so that would bring to you above $10 per ton. When you start looking at the leverage from our facilities, given that we were at around 50-ish percent in the first quarter for utilizations of plants going to 80%, 85%, that should really help bring our average production cost per ton down, closer to that ideal number of $12 to $13 a ton across all 4 plants. And so that could add another $3 to $5 a ton in contribution margin. The other impact there is the utilization of our railcars and more unit train shipments. In the first quarter, we shipped, I believe, 52 unit trains, and as Bob mentioned, that about 45% of our cars were shipped via unit trains, we're expecting to increase that to over 60% in the second quarter and we'll ship a number more unit trains. I think right now we're shipping at least 1 a day, if not more than that, per day. And that will also have a good impact on our contribution margin per ton in the second quarter.

Again, these assumptions are based on where the oil and gas industry goes from here. The chance of another prolonged slump in oil prices seem far fetched considering how little investment is taking place outside the U.S. shale patch, but it is always a possibility shareholders should be ready for.
