Biolin Scientific’s Theta High Pressure optical tensiometer helps oil and gas engineers understand and control reservoir wettability – one of the key parameters governing remaining oil‑in‑place and the success of enhanced oil recovery (EOR) methods. With high‑pressure, high‑temperature contact angle and interfacial tension measurements, Theta High Pressure reveals how rock, crude oil, brine, surfactants, nanoparticles, CO₂, and smart‑water formulations interact under realistic reservoir conditions.
This makes it faster and easier to screen chemicals for wettability alteration, compare EOR strategies such as surfactant flooding, nanofluids, CO₂ injection, and low‑salinity water, and quantify how far a system has shifted from oil‑wet toward more water‑wet long before full core‑flood tests.

Stable oil–water emulsions are a major challenge in oil production, leading to high water cuts, pipeline corrosion, and costly downstream processing. Biolin Scientific instruments help production and flow assurance engineers understand how interfacial films stabilize these emulsions and how chemical demulsifiers break them.
Demulsifiers are surfactants designed to break oil–water emulsions, with water‑soluble types typically used for oil‑in‑water systems and oil‑soluble types for water‑in‑oil systems. By measuring interfacial tension and interfacial rheology, you can screen and compare demulsifier chemistries, adjust dosage, and evaluate how efficiently dispersed water droplets flocculate and coalesce into separate oil and water phases before field trials.
Asphaltene deposition is a major flow assurance challenge in oil and gas production, contributing to fouling, altered wettability, and restricted flow in pipelines and process equipment. Understanding how asphaltenes from different crude oils adsorb to relevant surfaces under varying solvent and process conditions is essential for predicting deposit formation and designing effective mitigation strategies. QSense QCM‑D provides real-time, surface-sensitive insight into asphaltene layer buildup and structure, supporting better fouling control and more reliable production. This application note illustrates how QCM‑D can be used to characterize asphaltene–surface interactions in detail.
