GEOGRADIENT

GEOLOG offers two types of overpressure detection:
  • Real time “d” Exponent
  • GeoGradientTM
REAL TIME “d” EXPONENT
GEOLOG is the only Mud Logging Contractor offering the real time “d” Exponent in its standard mud logging service package.

The Data Processing is done continuously, and the “d” Exponent display is available at any time to rig users and to the client in town via real time data transmission (Wellcoms).

Screen Display
  • Real Time “d” Exponent  analysis while drilling
  • Continuous & immediate  calculation of the formation (pore) gradient
  • Continuous & immediate calculation of the fracture gradient
  • Immediate recognition of a change of  formation and pore pressure gradient

GEOGRADIENTTM PACKAGE – PRESSURE ANALYSIS and PREDICTION


The GeoGradient service consists of:
  • The GeoGradient software developed in house by GEOLOG
  • A dedicated Specialist
PRE-DRILL ANALYSIS  (PREDICTION)

It is performed during the planning phase of the well, collecting Regional data and offset data from other wells.

GeoGradientTM uses raw data like
“d” Exponent as an input
NCT applied to raw “d” Exponent shows
overpressure
GeoGradientTM processes the raw data to
recognize trends
From trends the pressure log is produced
