All operations were conducted in strict compliance with technological work plans and supervised by Idzhat’s specialized workover crews.
Below are the complete testimonial letters from our partners, detailing well counts, treatment volumes, and production responses.
Since 2017, Idzhat has been performing enhanced oil recovery operations using its own technologies and workover crews at the fields of LLC “UDS Oil.” The targets for treatments using Polymer-Dispersed Systems (PDS) technology have been injection wells at the Yalykskoye field. These wells target productive carbonate deposits of the Podolsk, Kashirsk, and Vereysk horizons of the Middle Carboniferous period, as well as terrigenous deposits of the Visean stage.
From 2017, a total of 26 treatments have been conducted across 7 wells, with injection volumes ranging from 1,887 to 12,580 barrels per treatment. The total incremental oil production achieved amounts to approximately 147,280 barrels: 10,445 barrels in 2018, 128,730 barrels in 2019, and 8,105 barrels in 2020.
In the process of planning and executing these operations, Idzhat has demonstrated a high level of professionalism. All treatments were carried out in strict accordance with the technological work plans and were completed on schedule as per the planned work program.
We extend our appreciation to the team of JSC Idzhat for effective and productive cooperation.
Respectfully,
General Director Yu. V. Shlyapnikov
Extensive experience in well treatment operations has enabled Idzhat to organize the work in full compliance with the specified requirements, to a high standard, and in adherence to the well treatment schedule. All operations were conducted under the supervision of highly qualified Idzhat specialists with significant experience in enhanced oil recovery (EOR). Idzhat carried out EOR operations at the fields of LLC BayTex using its proprietary technologies (Multifunctional Action Reagent (RMD) and ULTRAFLO-N) and its own well treatment crews.
In 2017, the treatment targets were injection and production wells in productive terrigenous formations of the Lower Carboniferous, as well as in carbonate reservoirs of the Middle and Lower Carboniferous. The new energy-saving integrated ULTRAFLO-N technology is designed to equalize the injection profile in injection wells and stimulate the productivity of oil-saturated interlayers. The comprehensive action of this technology on the oil-water-saturated formation is based on the combined application of flow-diversion technology and the ULTRAFLO reagent. This simultaneously increases the sweep efficiency and the oil displacement coefficient from the reservoir by utilizing the energy of phase transitions under reservoir conditions. As a result, previously undrained oil reserves are brought into development.
The key feature of the Multifunctional Action Reagent (RMD) technology is the comprehensiveness of its impact. The reagent contains a significant amount (from 20%) of a hydrophobizing component, which alters the relative phase permeabilities for oil and water. The flow resistance in the porous medium to oil decreases by 10-12%, while in water-saturated pores, the flow resistance increases by 10% or more.
A total of 16 wells were treated: 13 production wells using the Multifunctional Action Reagent (RMD) technology and 3 wells using the ULTRAFLO-N technology.
The results of the operations employing the Multifunctional Action Reagent (RMD) and ULTRAFLO-N technologies demonstrated that the technological effect manifested itself on all wells almost immediately after the treatments. The incremental oil production exceeded 5,000 tonnes (approximately 36,400 barrels), with the continuing effect.

Idzhat has been performing enhanced oil recovery (EOR) operations using its proprietary technologies and workover crews at the fields of JSC “Belkamneft” since 2003. The targets for these treatments have included both injection and production wells in productive terrigenous formations of the Lower Carboniferous, carbonate reservoirs of the Middle and Lower Carboniferous, as well as carbonate deposits of the Upper Devonian.
The primary operations employing Polymer-Dispersed Systems (PDS) technology were conducted at the Vyatskaya area, which is at a late stage of development (with average water cut exceeding 94%). Over 80 well interventions have been performed at the Vyatskaya area. According to Idzhat’s estimates, these treatments resulted in incremental oil production of approximately 862,000 barrels (118,446 tonnes) and reduced associated water production by more than 22.6 million barrels (3.6 million tonnes).
At the Vostochno-Postolskoye field, PDS injection into an injection well with a horizontal section yielded an incremental approximately 84,000 barrels (11,530 tonnes) of oil.
In the carbonate reservoirs of the Zabegalovskoye, Yuzhno-Listvenichnoye, Byginskoye, Chernovskoye, Buranovskoye, and Smolnikovskoye fields, 16 well interventions using PDS technology were performed. The estimated incremental oil production from these operations is approximately 144,000 barrels (19,828 tonnes), with a specific efficiency of approximately 7,600 barrels (1,044 tonnes) of additional oil per treatment.
In total, from 2003 to 2014, over 120 well interventions were performed in injection wells using PDS technology, including 57 treatments in the last three years of that period (26 wells in 2011, 18 in 2012, and 13 in 2013). The total estimated incremental oil production for 2003-2014, according to Idzhat, exceeds approximately 1.14 million barrels (156.4 thousand tonnes).

Using its Polymer-Dispersion System (PDS) technology, Idzhat performed 95 treatments in 47 injection wells at the Sovetskoye field from 2006 to 2009, with 29 wells receiving two or more treatments.
As of March 1, 2010, the current incremental oil production had reached 102,697 thousand tonnes (approximately 747,600 barrels), with the effect still ongoing. The effectiveness of the PDS impact is demonstrated both by a decrease in the water cut of the produced fluid and a reduction in associated water production (1,364.9 thousand tonnes for the mentioned period).
Based on the results of the PDS injections conducted at the Sovetskoye field in 2006-2009 and “Idzhat’s” experience at other fields in Western Siberia, we decided in 2010 to implement PDS injections at other fields of JSC “Tomskneft” VNK. From March 27 to June 1, 2010, injections were performed in 9 injection wells at the Dvurechenskoye field. Well tests show a positive trend of stabilizing or reducing the water cut in the responding production wells.
The achieved efficiency of PDS application at the oil fields of JSC “Tomskneft” VNK, under conditions of reservoirs with a high degree of permeability anisotropy, confirms the necessity of employing robust flow-diversion technology systems, such as PDS.
Head of the Waterflood Management Department S. A. Vezhnin
Idzhat has been performing operations in injection and production wells using its own well-chemical treatment crews since 2003, applying technologies for enhanced oil recovery (EOR) and water shut-off.
The primary operations were conducted in the producing well stock (23 wells) of the Kiyazlinskoye, Lugovoye, Cheremukhovskoye, Melnikovskoye, Ozernoye, Kuchukovskoye, and Yenoruskiskoye fields of LLC “TatRITECneft” using water shut-off technology with the gel-forming composition GOK ShSPK.
As a result of the treatments, the water cut of the produced fluid was reduced from 88-99% to 6-12%, and the oil production rate increased by 1.6 to 8 tonnes per day.
Operations were carried out in 5 injection well sections of the Kiyazlinskoye, Yenoruskiskoye, and Vostochno-Anzirskoye fields using GOK ShSPK technology (2005 – 2 wells) and PDS (Polymer-Dispersion Systems) technology (2013 – 3 wells). For the treatments performed in 2013, the incremental oil production amounted to 2,568 tonnes (approximately 18,695 barrels) as of July 1, 2014, with the effect still ongoing.
All treatments were performed in strict accordance with the technological work plans and completed on schedule as per the planned work program.
