Technologies of the company

• 3D Seismic: 3D seismic is a powerful method of geophysics used for hydrocarbon exploration and field development. It provides detailed insights into subsurface structures, fault geometries, and potential hydrocarbon prospects.
• Hydraulic Fracturing: Hydraulic Fracturing, or Fracking, is the process of creating a conducive path for hydrocarbons to flow from the reservoir to the wellbore in low-permeability reservoirs through the high-pressure injection of fracking fluid, primarily water containing sand or other proppants.
• Enhanced Oil Recovery (Polymer Flooding): Enhanced Oil Recovery (EOR) through Polymer Flooding is an advanced technology deployed to boost oil recovery, especially in mature and declining oil reservoirs containing highly viscous crude. The addition of polymers to the water enhances oil displacement and significantly improves the recovery factor.
• Artificial Lift: Artificial Lift provides the necessary energy to bring fluids to the surface, significantly enhancing well productivity. Globally, majority of oil and gas wells utilise artificial lift techniques.
• Skin Effect Heat Management System: Skin Effect Heat Management System (SEHMS) technology is a proven electrical heating solution used for long-distance piping and pipelines. SEHMS generates heat on the inner surface of a carbon steel heat tube welded to the carrier pipe.
• Enhanced Oil Recovery (ASP Flooding): Alkaline-Surfactant-Polymer (ASP) flooding is an advanced Enhanced Oil Recovery (EOR) technique, where alkali, surfactant, and polymer are injected into the reservoir to displace crude oil.
