Microproppant improves production
CARBO’s NANOMITE microproppant is a fraction of the size of the smallest proppant commonly deployed and is offered in both ceramic and sand versions: NANOMITE C and NANOMITE S. This cost-effective offering is for operators experiencing difficulty with proppant placement, elevated treatment pressure and early screenouts during treatment. Traditional proppant is too large to fit into a complex fracture network’s microfractures, and its transport characteristics limit how far it travels into the area. NANOMITE C’s smallest particles are more than five times smaller than the smallest particles in 100 mesh frac sand. This allows the particles to prop open even the narrowest secondary fractures and microfractures experienced in complex fracture networks. NANOMITE ensures operators’ microfractures contribute to production, increases propped reservoir volume, diminishes treatment pressure and ensures long-term well productivity for operators. carboceramics.com
Company highlights proppant data, features resin-coated frac sand
Covia provides oil and gas completions solutions spanning any well environment in all major basins. At the SPE Hydraulic Fracturing Technology Conference, the company will showcase the value of an engineered approach to proppant selection, the incremental benefits of resin-coated sands and a comprehensive mineto- wellhead, full service supply chain.

Covia is introducing Backstop, the Permian’s dedicated proppant flowback sand. Backstop is a resin-coated in-basin frac sand that ensures proppant stays in the well where it belongs. coviacorp.com
Smaller footprint, higher horsepower of frac pump decrease costs
Cudd’s new Q-3000 frac pumps deliver maximum efficiency, durability and lower operating costs, requiring a smaller footprint compared to a conventional lower-horsepower fleet. These powerful units are the first final Tier 4 emissions-compliant, diesel-powered 3,000-bottomhole-pressure frac units in the industry. They provide more than 2,800 hydraulic horsepower (hhp) at pressures up to 14,000 psi (higher pressures available with 4.5-in. plungers). The 550-gal fuel capacity enables extended pumping operations with higher fuel efficiency and power density per spread. The Q-3000 pumps include an exhaust gas recirculation system that reduces emissions without compromising performance and does not require diesel exhaust fluid or diesel particulate filters. A smaller footprint with increased horsepower means less nonproductive time and improved safety, all of which contribute to a lower operational cost. cuddenergyservices.com
Valve addresses operational challenges of diverter
The impact of pumping large volumes of diverter through stimulation pumping equipment is a wellknown industry challenge. DiverterPlus and National Oilwell Varco (NOV) have coordinated their efforts to minimize or eliminate the accelerated wear and potential damage that can occur when particulate diverter embeds into the valve insert. Through manipulation of the polymers’ mechanical properties and geometries via new manufacturing techniques of its Div+ line of particulate diverters, DiverterPlus has been able to eliminate the need for additional equipment in aggressive diversion deployments. Utilizing NOV’s Blue Thunder valve and the additional data gained from cooperative development, the insert compound used with the valve is highly resistant to wear and exhibits none of the problematic embedment issues traditionally associated with large particle diverters. The combined system eliminates downtime risk and potentially costly maintenance, allowing pressure pumping operations to continue at their maximum efficiency. diverterplus.com, nov.com

Importance of tank monitoring and asset tracking
Using measurement tools in storage and transportation tanks has a positive effect on the efficiency and lifetime of chemicals and equipment. Liquid monitoring and asset tracking technology play a huge part in the monitoring of chemicals from the chemical companies to the final user and can help ensure timely delivery and real-time monitoring of quantities of chemicals contained. When selecting asset monitoring solutions, there are several main points to consider. These include looking for a range of scalable solutions with viable costs and capabilities to fit needs and budgets. It is important that the solution is tailored to a direct need. Tangible value and benefits should be aligned with a company’s operational goals and objectives. Additionally, technology options, such as satellite and cellular, should accommodate difficult transmission from remote locations. hooverferguson.com
Platform uses data to help operators improve production
FracRx is the formalization of MicroSeismic Inc.’s data analytics and synthesis platform integrated with multiphysics data that show operators precisely when to start or stop fracturing in real time based on rate of return. FracRx focuses on drilling profitable wells by constructing a complete stimulated reservoir model based upon a propped and unpropped discrete fracture network, as illuminated by the monitoring data, using MicroSeismic’s technique. After building an economic model based on the operator’s cost and price decks, FracRx performs a reservoir simulation to estimate fluid volumes produced and drainage volumes achieved over time, and then it creates a financial model to estimate the most economic (greatest net present value) completion parameters. The platform offers a complete description and map of the treated reservoir, including drainage volume, during the frac by delivering the stage-by-stage answers that engineers want and need to improve production and increase asset value while pumping. microseismic.com
Diverter hydrolyzes faster in lower temps
Historically, degradable polylactide (PLA) diverter functionality has been limited to wells greater than 150 F. While PLA-based products could adequately divert below 150 F, they were slow to hydrolyze at these cooler well temperatures. Commercial alternatives that would hydrolyze faster at low temperatures tended to present handling issues, sometimes requiring refrigerated storage. Developed with A. Schulman, NatureWorks’ Ingeo DH1000 hydrolyzes up to four times faster at downhole temperatures in the previously unmet range of 120 F to 150 F while retaining the inherent mechanical properties of PLA. In addition, DH1000 is delivered to the well site in pails or bags and requires no special handling. Available in formulations of varying particle sizes, these diverters can be used in near-wellbore as well as far-field applications where they can be employed to minimize the incidence of frac hits. Commercially available in 2019, DH1000 has been placed in more than 75 wells across the Permian Basin as well as several international trials. natureworksllc.com
Proppant delivery system lowers trucking costs
Proppant Express Investments LLC (PropX) is a privately held company headquartered in Denver. PropX is a last mile containerized system for frac proppant delivery from mine or transload terminal to well sites. The system is designed to lower last-mile trucking costs, end truck traffic, eliminate demurrage, offer more flexible maximized load volume and produce less dust and noise than incumbent methods, as well as allow some of the highest throughput frac operations in the world (greater than 9 MMlb/d per crew in several instances). The ability to unload and load sand containers in less than 10 minutes (versus 45 minutes for the same proppant mass with pneumatic transfer) dramatically reduces the truck staging problem and demurrage fees charged by the truckers while standing by waiting on their turn to unload. PropX deliveries incorporate a smartphone and desktop app, which provides fast, easy ordering of sand, trackability of loads by driver from terminal to well site, sand inventory at the well site and frac stage report summaries. propx.com
