Offshore Sulfate Detection
Waterflood injection in offshore oil production requires water with extremely low sulfate (SO₄²⁻) concentrations to prevent operational challenges. High sulfate levels can lead to the formation of barium sulfate scale, which reduces reservoir flow, and the generation of hydrogen sulfide (H₂S), which can sour wells and increase safety and environmental risks. Maintaining low sulfate concentrations in seawater used for injection is critical to ensuring efficient and safe production operations.
Traditional methods for monitoring sulfate rely on wet chemistry titration, typically performed once or twice per shift. While accurate, these techniques are time-consuming, often requiring 1–2 hours to deliver results. This delay limits the ability to respond quickly to changes in sulfate levels, potentially affecting process control and efficiency.
Your Simple, Cost-efficient Turnkey Solution
By automating the measurement process and providing real-time data, HORIBA’s Raman technology sets a new standard for sulfate monitoring in waterflood injection operations. It enhances operational efficiency, reduces the risk of scaling and souring, and provides refiners with a robust tool to optimize offshore oil production processes. As the only company offering this level of real-time, in-situ monitoring for sulfate, HORIBA delivers a unique and valuable solution for the industry’s most demanding applications.
On-Line Sulfate Monitoring For Waterfoold Projects
HORIBA’s Process Raman technology offers the only reliable, in-situ solution for continuous sulfate monitoring in waterflood injection operations. Raman spectroscopy eliminates the need for consumables, sample preparation, and frequent manual interventions. Its unique capability to detect the distinct Raman peak associated with sulfate allows for precise, real-time measurements without interference from water in the sample.
With sensitivity to sulfate concentrations below 45 ppm, HORIBA’s Raman analyzers deliver accurate monitoring across a range of detection limits. This capability provides instantaneous feedback for changes in sulfate levels, enabling real-time adjustments to injection water treatment processes. The non-contact Raman sensor can be inserted directly into the treated water stream, while the base instrument is housed remotely in the control room for safe and easy operation.
