Centrifuge: The Ideal Tool For Wettability
A good starting point to many projects is usually rendering the wettability to a water wet preference without destroying the nature of the pore architecture.
Weatherford Laboratories offers a unique test design to determine wettability. Laboratory programs are created to ensure maximize results, which begin with a coordinated sample preparation and end with a focus on cost savings for our clients.
Wettability assessment is key in understanding reservoir properties and an essential part of our laboratory work. Centrifuge measurements are ideal for making wettability assessments of core fluid interactions. There are numerous wettability indicators, all of which can be determined through three carefully made measurements using Weatherford’s newly developed analysis software. This new technique uniquely positions Weatherford Laboratories to save time and money for the clients we serve.
Weatherford Laboratories offers cutting-edge technology advancements.
The Weatherford Imaging Centrifuge System (WICS) and the associated software have put Weatherford Laboratories ahead in the field of wettability determination. Results have been a reduction in time required to run centrifuge experiments through extrapolation, simultaneous capillary pressure, and relative permeability measurements. This productivity has the potential to reduce cost for our clients.
Major Factors Influencing Wettability:
• Mineralogy of the core material
• Acid and base ratios and amounts in the crude oil
• Brine pH
• Brine salinity
Centrifuge testing can closely match these critical criterion to mimic reservoir wettability.
