Description

Course Description

Shaly Sand Formations, which are also called low-contrast or low-resistivity pay zones are present in all the petroleum basins around the world in particular the river delta depositional environments.

The course is designed for

  • Petrophysicists
  • Exploration Geologists
  • Production Geologists
  • Exploration Managers
  • Well-site Geologists
  • Operations Geologists
  • Geophysicists
  • Well Data Managers
  • Geotechnicians

Learning objectives

  • To introduce participants to the complexities of Shaly Sandstone Reservoirs / Low-contrast or Low Resistivity reservoirs.
  • To determine and review of reservoir parameters using highly advanced petrophysical methods such as Dual Water, Waxman-Smiths, Simandoux and Juhasz methods.
  • To understand the various Shaly-sand petrophysical models such as laminated clay, dispersed clay.
