Research Facilities

High Performance Computing Environment (HPCE):

Realistic models of subsurface systems are invariably complex and computationally intensive. To run large-scale simulations, the lab members have access to a dedicated 13 node cluster. Each node of the cluster is powered by an Intel Xeon Gold 5218R 2.10 GHz 20-core processor and has 4x32 GB DDR4 2933 MHz Memory. In addition, the lab members also have access to the Aqua Computing cluster through the P. G. Senapathy Computing Center at IIT Madras. The Aqua cluster is a state-of-the-art supercomputing facility with a total compute power of 700 TFlops.


Automatic Environmental Triaxial Apparatus:

The environmental triaxial facility is a one-of-a-kind experimental setup which can be used to characterize materials such as gas hydrates, soil and rock. This highly sensitive apparatus is capable of applying a confining pressure of 20 MPa and control temperature between -20º C to 60º C, thereby simulating the in situ reservoir conditions in the laboratory. Additionally, the presence of gas pressure controller helps in understanding the coupled behaviour of geomaterials. This state-of-art facility will be used to understand the geomechanics aspects of subsurface reservoirs.


High-Pressure Pump:

High-Pressure Pump (Teledyne Isco Syringe Pump 500D) is used for pumping fluids and drilling muds up to a flow rate of 200mL/min at pressure up to 25 Mpa (≈ 259 Bar). This pump has a 500 mL cylinder capacity for a single fill and can deliver a precise 1 mL/min for about 8 hours. We will use this pump in experiments for injecting fluids (for constant pressure and constant injection rate) to understand subsurface reservoirs' fingering/fracturing morphology and geomechanics.
