TEM and EM-IP

A. WHY EM ?

  • Electromagnetic methods are advantageous tools of petroleum and mineral exploration and development, broadly used worldwide for being highly effective, safe, environment friendly, and reasonably costed
  • We perform 2D, 3D, and 4D electromagnetics to help our clients solve successfully different problems in geosciences
  • With integrated technologies and advanced instrumentation, we can work all year round in any climate environments, in taiga, tundra, wetland, jungle, or desert terrains
  • EM survey produces a geoelectric profile that give lithological and structural information, and a broad pattern of reservoir distribution may be discernible in the scheme of exploration
  • The value of TEM and EM-IP which will most complement seismic is the resistivity and polarization anomalies over the targeted traps. In many cases TEM is seen to improve seismic interpretation especially where seismic coherency is limited

B. SERVICES

  • IERP delivers a full range of EM surveys for petroleum and mineral exploration and development
  • The EM data enable our clientele to enhance the geological performance, improve the prediction quality, and choose the best design and configuration of more expensive surveys

C. PROSPECTING

  • 2D electrical prospecting on a network of regional profiles is intended to :
    • investigate the subsurface resistivity along the profile
    • model local geology
    • find oil and gas prospects
    • optimize well placement and reduce predrilling risks
  • EM acquisition shall try to follow and thus able to high grade, or provide for better and more reliable geological interpretation

D. EXPLORATION

  • 3D electrical prospecting is run on dense grids and furnishes comprehensive information on geology and resistivity of sediments down to 5000 m and deeper
  • Exploration aims at more thorough investigation of prospects, reservoir characterization, and predrilling assessment
  • The exploration outputs are :
    • high resolution resistivity models of reservoirs and prospects
    • reservoir characterisation
    • estimates of drilling conditions, with focus on zones of circulation loss and overpressure
    • detection of aquifers useful for drilling
  • EM surveys create a background for safe and effective drilling strategies

E. DEVELOPMENT

  • EM surveys help improving development solutions for oilfields and mineral deposits, due to :
    • 4D time lapse monitoring of subsoil and reservoirs under development
    • updating prospect locations
    • engineering geological surveys for construction of pipelines and utilities
    • environment monitoring during development
  • Acquired at high space-time resolution and processed with advanced noise attenuation algorithms, our EM data are of high quality even when coming from industrial and urban regions, including the areas of petroleum production and mining
