The breakthrough equipment creates earthquakes at the payzone level in the oil well.
Scientists of the Mining Institute, the Siberian Branch of the Russian Academy of Sciences (Novosibirsk) have developed new equipment that is unique in terms of capacity and mode of action and that makes it possible to increase the efficiency of oil recovery by 15 to 20 percent.
The concept of the invention was prompted by the observation of earthquakes, the head of the department "Scientific and Engineering Center for Mining Machines and Geotechnologies" of the Institute, Andrei Savchenko, reported to journalists at the press center in Novosibirsk.
 
The invention will be presented at the venture fair in the framework of the 6^th Technological Development Forum "TechnoProm", which is being held in Novosibirsk from August 27 to 30. TASS is the general information partner of the TechnoProm Forum.
 
“There was observed a significant increase in oil recovery after earthquakes or mass explosions. It is a very short-term process, so the goal was to make this impact long lasting or permanent.  As a result we got a 15-20 percent increase in oil recovery over the extraction site”, - Mr. Savchenko said.
He said that earlier large machines were used in order to replicate the effect of earthquakes by affecting the ground surface. This was a very expensive technology, so Siberian scientists decided to go further - they invented devices that descend into the oil well and create earthquakes at the payzone level.
"Each oil well is filled with liquid of about 1 km deep. The principle of operation is that we lift this pillar of liquid and through it into the bottom, which results in a colossal energy of over 30 kilojoules – with such impulses we operated in the well,” – Mr. Savchenko explained to media.
One device affects the wells in the radius of up to 1.5 km. There was an effect when some of them yielded an increase of up to 6 tons of oil extraction per day. Mr. Savchenko specified that similar equipment is produced by other companies as well, but the analogs give significantly less energy and do not make pumping oil from the well with equipment possible.
Tests have already been carried out in the oil fields of Bashneft and Belkamneft, now they are conducted by Tatoilgas, a subsidiary of Tatneft.
