36 | April 2018 | hartenergy.com WATER MANAGEMENT: TECHNOLOGY "For larger capacities, if we go from 10,000- to 20,000-bbl/d units, then we would recommend deploying OilPaq modules in a purpose-made build- ing," he noted. APATEQ uses ceramic membranes for the OilPaq, so there is no real wear and tear on the components. "Members of our team developed installations with ceramic membranes over 12 years ago that are still running in the field today," he continued. The smallest system is installed in one 40-ft ship- ping container and two 20-ft containers. The larger container holds the ultrafiltration membranes. One of the 20-ft containers holds the pretreatment, while the second 20-ft container holds the control cabinet, the office and a storage space. The system is fully automated. It doesn't need an operator full time, and it can be remotely mon- itored and controlled. One person can operate sev- eral OilPaqs from multiple interface platforms (e.g., desktop, laptop and cellphone). On site the operator would check the levels, any leakages and the working of the pumps as well as anything that is electric and has moving parts. The system meets the highest international safety features, including IECEx. All critical operational subsystems are redundant to avoid process disruptions. System pulled by single pickup truck It used to be when 10 different people were asked what their treatment KPIs were, you would get 10 different answers, said Fountain Quail's Halldorson. "We're starting to see more com- monality now in what the industry needs for a treatment specification. "Typically they are wanting total suspended solids removal, oil removal and iron removal as well as making sure there is no hydrogen sulfide and that the product pH is neutral. We are starting to zero in on a common treatment specification and that makes our job a lot easier," he explained. The company is developing a new mobile treat- ment platform called the SCOUT. It is a filtration system that is completely automated and has no dis- posable media such as filter bags. This addresses one of the biggest costs for the company—manpower. "If I'm going to get to a very low threshold on costs, I need to remove or reduce the manpower part of the equation. So we started developing the SCOUT. We wanted something com- pact that would do a very good job of filtration," Halldorson explained. One of the company's goals is to safely reduce the manpower. "We can make a system that's fail-safe in the middle of nowhere in the oil field. If there's an upset, it has to shutdown and do it without the potential for spilling," he emphasized. Fountain Quail spent the better part of 2017 test- ing different technologies and now has a commercial system operating in West Texas. "We're building a next-generation system with a higher capacity that is more containerized," Halldor- son said. "Our real goal is to build a rugged system we can set up with a pickup truck that is capable of call-out type service. Our current generation is not that mobile yet." According to Halldorson the next-gen system was to be available March 1. The company is shooting for SCOUT to be a sys- tem in a 20-ft container capable of 10,000 bbl/d. "We have a lot of jobs where we may need 30,000 to 40,000 bbl/d," he said. "Four small containers in parallel would make sense. Most jobs need 10,000 bbl/d, but it sure is nice to have the flexibility to roll out mobile, modular systems. "The reason Fountain Quail wants the SCOUT to be so flexible is it allows us to go into almost any situation where there might be an existing pit full of dirty water," Halldorson added. "We can rapidly deploy, get the job done and get back to the yard quickly, safely and efficiently." The new Generation II SCOUT will be completely containerized and everything shown on the Generation I (above) will be built into the automated system. The new Gen II system was expected to be operational by March 2018. (Photo courtesy of Fountain Quail Energy Services)
