Thermal EOR challenges

Economical challenges

To produce enough oil in the decades ahead to meet global demand, the oil industry must find new ways of improving the recovery factor (RF) of existing ones.

The main methods, known as Primary and Secondary Recovery, include natural flow, lifting techniques such as Progressive Cavity Pumps, and water or natural gas injection to maintain reservoir pressure.

The next category of methods is called Enhanced Oil Recovery (EOR) -- also known as Tertiary Recovery. Thermal Recovery is the most widely applied method EOR. Heat is introduced into the reservoir by steam injection, in order to improve the oil displacement inside the reservoir.

Technical challenges

The existing main in-situ methods involve include thermal activation using:

  • Steam (SAGD – Steam Gravity Assisted Drainage, CSS – Cyclic Steam Simulation or steam drive)
  • Electrical heating (ET DSP electro thermal dynamic stripping process)
  • Combustion (THAI toe to heel air injection)
  • Solvent injection (VAPEX vapor extraction).

In thermal EOR, the key challenges are minimizing the steam/oil ratio (SOR), which indicates the energy spent per barrel produced, and increasing the recovery factor (leaving as little oil as possible in the reservoir when the well is abandoned).

Why choose PCM for the thermal EOR recovery?

PCM solutions

Another essential aspect when it comes to artificial lift is to find solutions that can remain efficient across a wide range of temperatures. Temperature variations are greatest in CSS applications (from steam above 250°C to almost cold production), and also during the warming period of a SAGD well. PCM Vulcain™ offers this versatility.
