  • Liquid-Liquid Unsteady State Relative Permeameter
  • Pendant Drop Contact Angle and IFT Measurement
  • HP-HT Pendant Drop IFT Measurement
  • Spinning Drop IFT Measurement
  • Mixer
  • Acid Core Flooding apparatus

This apparatus is designed to inject acids and other stimulation fluids into one or two rocks sample (parallel flooding) at reservoir conditions. The main objective is dissolving the reservoir rock or minerals/ deposits present in the rock to restore/improve the natural permeability of it. Equipment mainly consists of the syringe pumps; pre-flush fluid/ diverting fluid/acid accumulators; the core holders; the data acquisition system; and the back pressure regulators. The unit allows for constructing the acid response curve in terms of pressure drop or permeability versus time or amount of injected acid. The efficiency of different HCL-HF formulations to attack plugging minerals and effects of flow rate and temperature on core sample permeability can also be studied.
