Hidrofrac´s AST tank system is available in different sizes:
• Quick set up and tear down
• Cost efficient
• Reduced ground disturbance
Tanks can be lined with different types of liners according to the fluid that is to be stored, usage time and customer’s needs. These are UV protected to improve lifespan and can be made from different materials like PVC, Composite PE, etc; to store water, flowback or chemically aggressive fluids.
Hidrofrac® bird netting and covers protect the tank and the contained fluid in several ways.
Hidrofrac® bird nets are made from a HDPE net and have an independent steel structure which keeps the bird net in horizontal position, preventing it from coming into contact with the stored liquid.
Its function is avoiding contamination of clean water with the organic matter from birds, which could cause bacteria growth, and avoiding contamination of birds, caused by coming into contact with produced water or flowback which could be stored in the tank.
Hidrofrac® floating covers are made from a floating liner with a perimetrical fastening system which allows the cover to float on the water surface, fluctuating according to the liquid volume contained in the tank, and keeping the stored liquid isolated from the exterior. In storage tanks for frac water, these covers prevent the entry of dust, water evaporation on hot days, possible water overflowing on windy days, and UV radiation from enabling the growth of bacteria and algae, which has a serious impact on the reservoir due to H2S formation. In tanks storing produced water and flowback, these covers are essential to comply with environmental standards which demand the isolation of the water surface from the environment, to avoid contamination of birds and evaporation of volatile substances used in fracturing operations.
Local regulations demand secondary containments around oil, flowback or produced water storage tanks, creating an additional containment in case of leakage. Hidrofrac offers two systems for this purpose, nested tanks and Nested tanks are two Hidrofrac tanks, set up one into another. For lower ground disturbance, it is recommended a 4,5 m high as main storage tank, and a 3,0 high as secondary containment tank Secondary containment walls are built around the main storage tank from precast concrete panels, bolted to each other, with an HDPE liner inside; and are able to contain possible leakages. These are designed and calculated to withstand hydrostatic pressure, and are in compliance with the current regulations of Argentina´s Department of Energy.
HIDROFRAC® provides a comprehensive water transfer service, including the design of the facilities, the provision and set-up of equipment and highly qualified on-site operators.
This service is suitable for non-conventional hydraulic fracturing operations, drilling with circulation loss, water transfer from source to storage, loading and unloading of water tanker trucks, hydraulic testing of oil and gas pipelines, dewatering, fire fighting and other requirements of water transfer that can arise in the oil & gas industry as well as in other industries.
The pumping system is designed and operated by hydraulic specialists who determine the type of pump, its settings and other required equipment, after an exhaustive study of the required flow rate, the load loss according to pipe type, the pipeline length, the level differences, the number of pumps needed to guarantee a safe operation, the working pressure, etc.
Our equipment includes the supplying of centrifugal motor pumps, manifolds, temporary pipelines of TPU layflat hoses with no-leak couplings, and man camps for operators. The pumping system can be operated for 12 or 24 hours, depending on operation’s needs. In water transfer operations in non-conventional well sites, flow rate can vary between 30 and 100 bbl/min, depending on the operation design, and whether 10” or 12” layflat hose pipeline is used.
In flowback or produced water transfer, flow rate can vary between 10 and 30 bbl/min, using centrifugal pumps suitable for fluids with hydrocarbons and chemical resistant pipes with no-leak couplings.
• Road crossings: fast and effective solution when temporary pipeline needs to be deployed across roads in location.
• Pipeline pigging: used to empty and clean the pipeline, before disassembling, when produced water and flowback has been transferred, or when, due to environmental restrictions, it is not possible to discharge the remaining water present in the pipeline, once the water transfer operation has concluded.
HIDROFRAC® offers fresh water treatment service in order to prevent algae and bacteria growth, that could negatively affect the operation causing H2S formation. This service includes careful selection of technologies and biocides, as well as other chemicals, in order to keep water quality stored in tanks or pits.
Our specialized team analyses each clients need and project, and select combination of technologies to treat stored or in the fly injection, such us:
• Pits and tanks aeration to reduce algae and bacteria
• Biocides injection for stored water
• On the fly THNM biocide injection
• Filtration in a wide range of flow rates and particle size
Remote monitoring system which measures and records variables such as level, pressure, flow rate and temperature. This tool optimizes costs and time in water management operations and records precise information about water needed in fracturing operations, which can be used for future analysis and presented to environmental protection agencies.
This system provides real-time data from storage points, as well as historical data, statistics, graphics, etc., which can be viewed by accessing an interactive site, from any place with internet connection.
This system works by means of sensors, placed within the modular tanks, above-ground storage pool and flanges in the water transfer system, which transmit data to customer through a satellite station. This data is collected by a server and processed, so that it can be monitored via website.
• Water provision can be controlled and optimized, evaluating delivery time, worked days, amount of water supplied, etc.
• Allows customer to know, at any time and from anywhere, amount of water stored in onsite tanks.
• It provides useful information to optimize the use of water in each fracturing operation, by collecting and storing accurate information about all the well variables, such as number of stages, well type, temperature, times, etc.
• Collected information can be used to make reports about the amount of fresh water used and flowback produced, which can be presented to environmental protection agencies.
• It is a useful tool to determine the amount of vaporized water and water loss through overflowing on windy days.
• It issues a warning when potentially risky levels are reached, such as minimum fresh water or maximum flowback level. This allows quick reactions and intervention to correct the situation.
