RokDoc Reservoir Characterisation from Ikon Science

RokDoc Reservoir Characterisation

Ikon Science’s RokDoc Reservoir Characterisation module allows you to quickly and easily use seismic data to understand the subsurface. Even with limited data, you can make more accurate and faster decisions with more confidence.

The RokDoc Reservoir Characterisation modules brings a range of sophisticated tools; convert existing inversion volumes into meaningful and accurate geological rock properties for prospect evaluation. The RokDoc 3D cross-plot allow users to integrate well, seismic and rock physics data and establish whether inversion results are consistent with forward models from well data.

Industry Challenges

Drilling costs increasing, hydrocarbon pool sizes decreasing
  • New frontiers geological uncertainties are considerable
  • Mature areas where traps can be very subtle and/or small
  • Old fields approaching end of life
Drilling success rates / well productivities are highly variable
  • Over reliance on qualitative interpretation techniques
  • Failure to adequately capture and incorporate uncertainty into models
  • Lack of cross discipline integration during model building and reserves estimation
Drilling and geophysical interpretation cycle times are out of sync
  • Inability to impact drilling decisions in fast paced projects
  • Time wasted and errors made transferring data between multiple software packages

Reservoir Characterisation Module

Intuitive:

Explore for, develop, prolong field life
