A knowledge-based company has produced a core acidizing device that helps improve the extraction process from oil wells.
Acidization is one of the widely used methods in the well stimulation process, which increases oil and gas production at a relatively low cost and in a short period, according to the CEO of Fanavari Ezdiad Bardasht Fars Company.
“Due to problems caused by sanctions and the high prices of foreign counterparts, the company produced an affordable and more efficient core acidizing device to meet domestic needs,” Moein Nabipour was also quoted as saying by the news portal of the Vice Presidency for Science and Technology.
He added that some factors in drilling operations significantly reduce oil and gas production.
“Formation damage due to drilling, cementing, meshwork, well completion, repair and stimulation operations can cause a reduction in oil extraction,” he said.
“The acidizing operation is usually the best method to improve well production and increase crust coefficient. The success of this operation depends on the type, concentration, volume and injection method of the acid, which are mainly evaluated and designed after conducting core acidizing dynamic tests.”
Nabipour stressed that the quality and type of additives used and the type of formation are decisive factors in the acidizing process.
“In this operation, acid is injected into the layers of oil and gas formations with different pressures to increase the production rate by opening the existing channels,” he added.
According to the CEO, the device can be used by oil and gas industries as well as drilling and production companies.
“The company is the exclusive producer of this type of core acidizing device in Iran. A limited number of foreign companies produce this device, but the Iranian model has better quality, efficiency and lower cost than foreign counterparts,” he said.
“The domestic core acidizing device has annually prevented the currency outflow of $20 million from making the import of foreign counterparts unnecessary.”
He stressed that the use of gas pressure regulator, accurate injection of fluids, recording and controlling all data during the test, smart management of overhead pressure to avoid any possible damage and the replacement of stainless steel with titanium or hastelloy are the main advantages of the domestic acidizing device.
Nabipour noted that the company has presently created 15 direct and 10 indirect jobs.
Plasma Treatment Equipment Purifies Wastewater for Reclamation
A knowledge-based company has produced wastewater treatment equipment using plasma and cavitation technology that purifies different types of wastewater for reclamation.
It can be used for the removal and neutralization of organic pollutants in industrial, mining, household and other wastewaters, treatment of hospital effluent containing toxic compounds and treatment of contaminated and toxic water with heavy metals and microorganisms.
The equipment is produced by Pishro Fanavar Tav Asia (also known as Panta Plasma) with the support of the Iran Nanotechnology Innovation Council, the news portal of the Vice-Presidency for Science and Tech reported.
The company claims that the facility eliminates all types of harmful microorganisms, polluting organic compounds and heavy metals in wastewater.
The ability to destroy stable materials, using limited space for the purification process, avoiding use of chemicals, lower cost compared with peers, removing heavy metals and reducing sludge volume during treatment are among the advantages of the new facility, the company says.
Amalgamation of plasma and cavitation technology in the equipment reportedly results in more efficient purification compared to other systems.
Plasma technology is the use of high-voltage electric discharge by creating high-energy points in water using methods such as arc discharge, glow discharge and dark discharge in a pulsed manner without increasing the temperature of the fluid, which will reduce energy consumption and increase discharge power in a shorter time compared with other methods.
Cavitation technology creates macro/micro cavities by using cavitation modules (orifice pellet, venturi, rotary and vortex) and creating a pressure difference. With the explosion of these cavities, high energy points are created in the fluid.
The pulsed plasma in the new facility provides an environment prone to the obliteration of pollutants by creating an electrical discharge in the water.
The company said it was able to boost efficiency by synergizing plasma and cavitation by controlling specific conditions.
