Introduction to Rapid Fracturing Fluid Flowback Technologies:
Rapid Fracturing Fluid Flowback technology employs the principle of gas-lift liquid unloading. Well fluid pressure gradient is reduced as gas is injected into the well, and the expansion of the gas accelerates the flowback of the fluid.
--------------------------------------------------------------------------------------------------------------------------------------------
There are mainly three types of applications for this technologies:
1. One-trip string for negative-pressure-perforation and fluid discharge technology:
Negative pressure is reached through gas lift, perforation and fluid discharge is achieved with only one trip of the work string. The cost is low and operation cycle is short. This technology has been used since 1994, and was applied on about 120 wells every year, totally on more than 2000 wells. The success rate of operation is up to 98%, the average time for fluid discharge is about 5 hours. It has been a commonly used technology.
2. One-trip string for fracturing and fluid discharge:
After fracturing, there is no need to trip out of the work string. Nitrogen is pumped into the annulus and fracturing fluid is discharged rapidly. Operational procedures are simplified, the time fracturing fluid stays in the formation is shortened reducing damage to the formation.
The fracturing fluid is discharged quickly, the efficiency is high, and the time needed for discharging all the fluid is only 4-8 hours depending on well depth and casing size.
Discharging rate is high, the fluid at the bottom of the hole can be discharged out.
Equipment needed is less, the process is simple, and the technology is reliable, the cost is low.
3. One-trip string for acidizing and gas-lift fluid discharge technology:
Suitable for rapid acid discharging after commingled or zonal acid treatment.
--------------------------------------------------------------------------------------------------------------------------------------------
Features:
The technology shortens the time fracturing fluid stays in the formation, minimizing the damage to the formation, and improves the effect of fracturing/acidizing, thus improving the oil and gas production;
1、Shortens the time for flowback;
2、Shortens remedial work period and allows the well will be put into production earlier;
3、Lower operational cost and improved comprehensive benefit.
