Water Analysis
Understanding the makeup of water in production and midstream operations is crucial in determining both scaling tendencies and risks as well as corrosion potentials and events. Utilizing these data points, prevention or risk reduction plans can be put into place to ensure consistent production and increase uptime.
Water Chemistry
Quantification of primary cations and anions of produced water are critical in understanding the corrosion and scale potential in oilfield matrices. All cations are analyzed by ICP-OES measurements. Chlorides are measured by argentometric titration, and sulfates are analyzed by turbidimetric analysis (SW-846).
Ion Analysis
Just need individual ions, and not the complete water chemistry? Let us know which ions you require, and we can tailor the testing to fit your purpose.
Scale Modelling
Scaling tendencies are determined by in house scaling software for accurate predictions of scaling potentials and quantities. Projects can also be completed for mixing waters to determine their compatibility with each other or multiple waters.
Corrosion Inhibitor Residuals
Identification and quantification of corrosion inhibitor residuals utilizing an in-house chloroform extraction method.
Scale Inhibitor Residuals
Identification of phosphorous based or phosphorous tagged scale inhibitor residuals by ICP.
Membrane Filter Analysis - TSS
Elevated suspended solids in production trains can be indicative of scaling upstream, oil carryover, or formation materials migrating to the surface. Membrane filters can be employed to sample the water for suspended solids and identify the breakdown of solids present. Alternatively, water samples can be collected and brought to Oracle for laboratory filtration and identification.
Oil and Grease in Water
Oil and grease discharge offshore is regulated by the EPA through monthly and yearly testing. Samples are quantified utilizing a modified version of EPA 1664 b - Hexane extraction.
