Fracjet-Volga

Fracturing

Hydraulic fracturing is one of most complex technologies in the oil & gas production industry. For over 50 years now, it has been used to enhance oil & gas reservoir recovery.

FracJet-Volga has s state-of-the-art frac fleet and qualified personnel to ensure highest quality of fracturing operations.

Acid Fracturing

Acid Fracturing

Acid fracturing refers to all fracturing operations that involve acid compositions instead of water to serve as the frac fluid. It is routinely applied in carbonate reservoirs. The cracks and caverns that result from high-pressure acid fracturing require no proppant. What sets it apart from acidizing is a more significant amount of acid used, as well as much higher pump-in pressure (which exceeds the formation fracture pressure).

FracJet has developed acid compositions that have proved efficient in the treatment of reservoirs featuring various temperatures and rock composition. Each job involves customized acid compounds which are designed following a series of lab tests of reservoir fluids and core samples.
Frac packing

Frac packing

Fracturing with proppants, i.e. materials designed to keep a fracture open and pumped in during a fracturing treatment, is referred to as frac packing. Frac pack technique is routinely applied in the treatment of terrigenous formations. Whenever “a fracturing operation” is mentioned, a frac packing job is most likely to be implied.

Our experts select the best fracturing composition for temperatures ranging from 8 to 150 С°. A wide range of chemical agents is used to develop fluids featuring various viscosity and shear properties, from low-viscosity linear polymers to high-viscosity crosslinked fluids. We design fluids to impart a set of required properties, thus ensuring stable and complete breakdown of the fracturing fluid.
CT Fracturing

CT Fracturing

FracJet-Volga has its own fleet of coiled tubing units. CT-assisted fracturing is an efficient solution for difficult reservoir conditions – those requiring fine and subtle intervention.
Nitrogen Fracturing – Foam Nitrogen Treatments

Nitrogen Fracturing – Foam Nitrogen Treatments

In the fracturing industry, this technology has long proved to be efficient in well completion and stimulation. When purged with nitrogen, polymer fracturing fluids feature increased viscosity, thus providing a cost-effective solution.
Multistage fracturing

Multistage fracturing

Multistage fracturing jobs involving packers with balls of various diameter are performed to isolate multiple zones. In our fracturing treatments, we apply Selective Packers, as well as high-viscosity polymer plugs that imitate packers and are easier to deploy and to release.
Fracturing with Surfactants

Fracturing with Surfactants

To change the properties of fracturing fluids, engineers may also opt for various additives. The use of surfactants ensures no-sediment fracturing. Even a low concentration of base components creates high-quality foam fluids of excellent stability, while large concentrations produce a high-viscosity elastic gel suitable for fracturing with a significant concentration of proppant added.

Blenders (Mixing Units)

The blender is designed to mix fracturing fluids with proppants and additives, with their subsequent feed to pumping units. It is equipped with reservoirs and precision delivery pumps, as well as two augers for proppant feed with the concentration of up to 1,800 kg/m3 (15.02 lb/gal), feed pumps for water-based additives (6 pumps) and bulk additives (3 pumps). It also has four (4) flowmeters and a density gauge. The blender features the maximum output of 8 m3/min (2,213 gpm). The blender is mounted on cross-country chassis.

Pumping Units

FJV fleet includes four pumping units 2,250 hp each with the aggregate maximum flow rate of 8 m3/min (2,213 gpm). Max working pressure – 103 MPa (14,940 psi). The unit is mounted on a heavy-duty tractor.

Data Van

The data van records up to 200 parameters during fracturing operations, controls all pumping units, the blender and the hydration unit. It is equipped with a power supply unit, controls and data displays, as well as a field laboratory. The van is mounted on cross-country chassis.

Hydration Unit

The hydration unit is designed to prepare and feed gels during frac jobs. It is equipped with reservoirs for chemical additives and three flowmeters (one at the input, and two at the exit). Maximum output - 8 m3/min (2,213 gpm). Also, it has feed pumps for liquid additives (3) and bulk additives (1) with Coriolis flowmeters. The unit is mounted on cross-country chassis.

Sand Feed Units

FJV fleet includes two Sand Feed Units with the aggregate capacity of 160 tons of proppant. Each unit is equipped with three separate feed tanks for various fractions. The unit is mounted on cross-country chassis.

Manifold Unit, High- and Low-Pressure Lines

The maximum working pressure of the high-pressure lines is 103 MPa (14,940 psi). The unit is mounted on cross-country chassis with a loader crane.
