Sweet spots

Multi-variant factors such as total organic content (TOC), clay volume, mineralogy, temperature (both palaeo and present day), natural fracture patterns, in situ stresses, pore pressure and permeability, all act to control or influence producibility rather than a single influencing factor.  These properties realise themselves in the operational behaviour of the rock under reservoir conditions. 

At Ikon Science we offer a multidisciplinary approach to map these properties, evaluate their impact on the state of stress, and understand the behaviour of the rock when subject to various operational procedures.  Multidisciplinary criteria derived from rock physics, geopressure and geomechanical analysis can be used to define specific behaviours in order to isolate optimally performing reservoirs.  These properties can be represented in the velocity domain permitting the use of seismic data to map these “sweet spots” away from well controlled locations.
