Acidizing fracturing hose specifications and models

The specifications and models of acid fracturing hoses


The specifications and models of acid fracturing hoses are used to transport various fluids in and out of the fracturing site. These include drilling fluids, crude oil or hydrochloric acid.

Foam-based fracturing fluids can be customized to individual reservoir conditions with environmentally friendly chemical additives. They can also be tuned for thermal changes that affect their rheological properties.

How to choose acid pressure hose
Choosing the right acid frac hose for your well is critical. These hoses need to be able to withstand high temperatures and pressures in the harsh environment of sour gases. To reduce the risk of failure, they must also be flexible and have low leakage paths. Choosing the correct acidizing frac hose will ensure a safe and successful operation.

Acid fracturing nozzles are typically made of polyurethane and must be rated for the acidic conditions within the well. The nozzle must also be able to withstand pump vibration and acceleration as well as the high temperature and pressure conditions found in sour gas environments. Hoses must be able to withstand high temperatures and pressures and resist wear and tear.

Acid-induced thermochemical fracturing methods use any type of low-pH acid to etch carbonate rocks and create fracture conductivity. This treatment activates various natural fractures within the reservoir, increasing daily and cumulative production. The method also increases the flow capacity of fractures, reducing fluid losses and improving well performance. It also minimizes the impact of the shutdown. The Fracturing Process uses the Net Present Value (NPV) module to calculate the economically optimal fracturing treatment. This module uses information about reservoir fluids and proppant to optimize fracture geometry.

Acid Fracking Hose Fittings
Premium acid frac hose is designed with end connections to resist damage from rough abrasive materials or surfaces. It should also be able to withstand high pressure. The hose should also be easy to clean and resistant to corrosion. It should be lightweight and short enough to prevent unnecessary rework. These hoses can be used to transport water-based, oil-based, acid-based and foam fracturing fluids at high pressures in acid, sand and hydraulic fracturing projects.

The fluid efficiency of acid fracturing is important because it affects the fracture length and flow conductivity of the wellbore. Higher fluid efficiency means less acid leakage and better performance. Fluid efficiency should be between 40% and 60%.

The etched morphology of the fracture is determined by the reaction rate of the reservoir and the dolomite composition. The etching morphology of dolomite is different from that of calcite rock, because the acid reaction is slow and the crack wall is not easy to form differentiation fingers. This etched morphology reduces acid consumption near the wellbore and increases the length of the etched fracture and the conductivity of the fracture. The crack sealing ability of the temporary plugging material is also critical. Fiber has a lower sealing pressure, but adding 10/40 mesh particles to the fiber improves crack sealing.

Acid fracturing hose production standards
In recent years, the production standards for acid pressure hoses have become increasingly stringent. The industry must meet multiple performance criteria, including flow, pressure, installation/disassembly time, leakage paths, and cost of ownership. These requirements are based on research, testing and field experience. These tests are performed under controlled conditions and may include testing under simulated fracture conditions. Test results are compared to production targets and a recommended hose design is developed.

A model has been developed that accurately predicts acid penetration distance. It is also able to incorporate the effects of rock type, acid injection rate and formation temperature. The model helps optimize acid treatment and maximize yield.

Optimization of acid systems in carbonate reservoirs requires high carbonate dissolution capacity and deep acid penetration to achieve long etch lengths. It is also important that the acid can be adequately suppressed under downhole conditions. During the development of the acid system, a mixture containing 7% HCl and 11% formic acid was developed. Acetic acid was removed from the mixture as it can cause incomplete inhibition under downhole conditions. The system performed well in the Pisces gas reservoir, increasing productivity by an average of 35%.
