It is widely recognized that 30% to 60% of hydrocarbons remain trapped in the reservoir even after primary and secondary recovery, forming what is known as residual (non-recoverable) reserves. The ultimate recovery factor is one of the most critical indicators of reservoir development efficiency. As fields mature and production declines, the challenge of maximizing recovery becomes increasingly urgent.
Traditionally, to increase the final oil and gas recovery ratio, operators apply pressure maintenance techniques such as water or gas injection, as well as thermal methods like in-situ combustion or steam flooding. While these methods are effective to a degree, they often fall short of reaching hydrocarbons stored in closed, low-permeability, or geochemically isolated pore spaces.
This is where MPC Technology makes a breakthrough. Developed as a multistage physicochemical stimulation method, MPC enables access to reserves previously considered unrecoverable. The technology initiates chemical reactions within the wellbore and deep in the reservoir, generating high-temperature gases and atomic hydrogen that penetrate far into the formation.
The core mechanism is based on the destruction of chemical bonds in clathrate and hydrate compounds, releasing hydrocarbons and passivating active mineral sites that would otherwise re-bind them. Once injected, MPC reagents undergo controlled reactions that gradually escalate in intensity as they move into the reservoir. Hydrogen atoms, with their extremely small size and high diffusivity, infiltrate closed or low-permeability pore spaces. Inside these isolated areas, they trigger a localized chemical reaction, briefly increasing temperature and pressure, weakening the internal structure of the rock.
As a result, even a minor pressure impulse — from the ongoing reaction or subsequent production — is enough to rupture the brittle pore walls, releasing hydrocarbons that were previously inaccessible. This chain reaction continues over days or even weeks, spreading deeper into the formation and connecting previously isolated zones to the active flow network of the well.
Field results have confirmed that MPC stimulation significantly increases the effective drainage volume of the well, activates previously passive formation zones, and leads to a notable uplift in cumulative recovery. In some cases, the treatment has triggered production increases not only in the treated well but also in neighboring wells located over 100 meters away, indicating deep radial penetration of the effect.
In essence, MPC Technology redefines the boundaries of recoverable reserves. By reaching beyond what traditional methods can access, it offers a safe, scalable, and economically sound solution for extending the productive life of fields and dramatically improving oil recovery rates.
