Get key formation data to improve hydrocarbon reserve estimates
The Array Dielectric eXplorer™ formation evaluation service from Baker Hughes, a GE company (BHGE), provides key petrophysical data to improve the quality of reserve estimates. Using multi-frequency dielectric technology, the service quickly and accurately determines hydrocarbon saturation with any formation water salinity.

Get reliable hydrocarbon saturation data
Conventional methods for saturation analysis rely on the contrast between the resistivity of formation water and hydrocarbons. When formation water is nonconductive or its resistivity is unknown, operators rely on time-consuming nuclear magnetic resonance logging or formation testing to identify hydrocarbon saturation. The Array Dielectric eXplorer service relies on dielectric permittivity data to provide hydrocarbon saturation in reservoirs with any water resistivity.

Make decisions at the wellsite
By providing real-time deliverables, such as water-filled porosity and water resistivity, the service quickly detects freshwater intervals and reveals the mobility of heavy oils. This offers operators earlier decision making opportunities for completion design straight from the field.

Acquire high-quality data in challenging conditions
The Array Dielectric eXplorer service features a dual-resolution sensor array to simultaneously acquire a large volume of data at a common measure point.
By obtaining a large volume of permittivity and conductivity data at multiple frequencies, the service creates a comprehensive data set to provide reliable input for inversion modeling of formation parameters. The service’s dielectric technology enables operators to quickly and cost effectively acquire data for improved saturation analysis. This analysis significantly increases the quality of reserve estimates.

Operate efficiently
The service runs at fast logging speed, and combines with all other BHGE wireline formation evaluation services to reduce time spent in the well—saving rig time and cost.
