Pressure / Temperature Surveys

FESCO well intervention wireline pressure surveys and temperature surveys

FESCO uses memory electronic pressure/temperature gauges to acquire the following types of reservoir BHP/BHT data:

  • Wellbore Fluid Gradient Surveys (Pressure and Temperature)
    • Static Gradient Surveys
      • Used to determine
        • Wellbore fluid types
        • Wellbore fluid interfaces (liquid levels)
        • Wellbore fluid densities
        • Wellbore pressure and temperature profile versus depth
    • Flowing Gradient Surveys:
      • Used to determine
        • Wellbore density profile versus depth
    • Lifting Gradient Surveys:
      • Used to determine
        • Wellbore density profile in a well producing via gas-lift
        • The working gas-lift valve
    • Temperature Gradient Surveys
      • Electronic Temperature Memory Tool
      • Temperature RTD located directly in the wellbore fluid for fast response
      • Used to detect small temperature changes in applications such as
        • Detecting cement tops after cementing casing in place
        • Holes in tubing while flowing, etc.
  • Pressure Transient Data
    • Test Types
      • Buildup Test
      • Drawdown Test
      • Falloff Test
      • Injection Test
      • Interference Test
      • Deliverability Tests
    • Wellbore Configurations
      • Vertical/Slanted
      • Horizontal
    • Well Types
      • Producing Wells
      • Salt Water Injection/Disposal Wells
      • Monitor Wells
