CONVENTIONAL CHECK VALVES HERMETICITY LOSS
PROBLEMS
Resulting in the fluid-backflow associated consequences.
SAFETY HAZARD
Ten-year statistical data* shows 1,189 fatal injuries in the USA in the oil and gas extraction industry.
REDUCED OR LOST PRODUCTION
Reduced production in the event of altered intermittent pump operation caused by fluid backflow in the tubing string, or a multi-day loss of production during both time and resource consuming well workover.
HIGH OPEX
High OPEX, engagement of well workover rig for pulling out of the entire production equipment, expenses related to transport and overhaul of that equipment, electric power costs, the reduced service life of electric submersible pieces of equipment
ENVIRONMENTAL IMPACT
Well workover can lead to groundwater contamination due to well-kill fluid ** utilization, and air quality degradation by exhaust gases from diesel powered rig and heavy machinery, operating 24/7, including their extensive fuel consumption.
THE RETRIEVABLE CHECK VALVE FLUID BACKFLOW
SOLUTION
SAFETY AT WORK
Reduced number of life-threatening incidents and injuries during well workover, involving contact with objects/equipment, exposure to harmful environments/substances, falls, and transportation.
OPEX REDUCTION
Operational cost cutting is achieved through a decreased number of well workovers, reduced accompanying equipment and personnel transport, lower frequency of pulled out equipment overhaul, and overall electricity savings.
UNINTERRUPTED PRODUCTION
Uninterrupted oil, gas, water, and gas condensate production process with maximum pump efficiency
direct loss-equivalent benefit annually*
ENVIRONMENTAL SAFETY
By avoiding associated well workovers, we eliminate the need for fuel consumption by workover rig, reduce exhaust gas emissions from the engines, and eliminate the utilization of fluid required for well-kill.
+ €1.1 million
DIRECT benefit within a single year
The losses outlined below are equivalent to the benefit accrued by the oil company through the utilization of the RCV due to the guaranteed designed operating mode on an annual basis.
FLUID BACKFLOW
(altered operating mode)
The conspicuously nonsensical consumption of electrical energy required for the operation of ESP equipment during the filling of the tubing string with fluid up to the point of its production on the surface. The power consumption for 80 minutes of ESP operation, attributed to tubing filling after the fluid backflow, costs the oil company 5.1 x €5.1 = €26 per day.
This calculation assumes that the electric motor and hydro-protector remain in functional condition, which is unlikely since they will most likely experience failures due to operating in a high-temperature regime, necessitating the overhaul of downhole production equipment.
*The average price of electricity in Serbia until August 2022 is 0.12 $/kWh. **This example should be understood as an approximate representation of the economic loss due to the non-hermeticity of conventional (nonretrievable) check valves, and in no way as a limiting parameter for the RCV and its performance.

Fluid Backflow Solution
Wrangtech’s innovative approach to the crude oil and gas production process lies in addressing the challenge of fluid backflow through ESP, ESPCP, or LESP equipment during pump stoppage due to the failure of the conventional check valve. The solution involves the utilization of a patented retrievable check valve (RCV) and its seating nipple during well-workovers. This eco-aware innovation eliminates the need for costly traditional well workovers, it completely replaces conventional check valves, and drainage valves in ESP, ESPCP, and LESP systems, in some cases. It leverages cross-disciplinary expertise encompassing pump engineering, fluid dynamics, materials science, and control systems to provide a cutting-edge product for the industry’s challenges.

CHALLENGE
BRING THE EQUIPMENT INTO OPERATIONAL MODE WITH MINIMAL LOSSES IN OIL AND GAS PRODUCTION, WITH NEGLIGIBLE ASSOCIATED COSTS.
The characteristic of conventional check valves is their non-retrievability, or non-replaceability without pulling the entire production equipment out of the well. Furthermore, the inclusion of drain valves is its indispensable accompaniment.https://wrangtech.com/wp-content/uploads/2024/07/0-02-05-753d62e585b1b35fc89a042f94a3b1b586c50233ca565b84230063248a7a581f_50bec6d28a585889.mp4
