Oilfield Scale Study and Deposits Analysis
Our capabilities include advanced scale inhibitor performance testing, and scale study and deposits analysis services,
addressing scale problems and incorporating strategies for prevention, prediction and remediation
The field of flow assurance is quickly expanding to include a wide range of analytical methods. With our expertise in chemical comparison, setting design criteria and looking for the source and mechanisms of deposits, DOSAS Oilfield Scale Study and Deposits Analysis can ensure you have uninterrupted, optimum productivity in your oil and gas streams.
Production tubulars and surface facilities are vulnerable to various types of scale formation, which blocks perforations and valves and accumulates throughout processing equipment. DOSAS Scale Solution, is a discipline that aims to counteract the effects of scale deposition and its negative impact on oil and gas infrastructure.

Scale Performance Laboratory Testing
|— Static Bottle Tests||— Dynamic Tube Blocking Test|
|The static inhibition efficiency (IE)(%) is a measure of how effective an inhibition solution is at preventing scale formation under a specific set of experimental test conditions, i.e. temperature, pH, etc., and at a particular time after mixing the two incompatible brines.||Dynamic “Tube Blocking” performance test (TBR), commonly used for scale solution selection in oilfield environments, partly examines the ability of Antiscalants to prevent adherence and growth within micro-bore coils and determine the minimal necessary solution concentration.|
— QCM Technique
Quartz Crystal Microbalance (QCM) is a very sensitive mass deposition sensor based on the piezoelectric properties of the quartz crystal. It is used for monitoring the scaling process from nucleation to the growth phase and provides an understanding of scaling potential and inhibitor efficiency.
— Compatibility Tests
Mixing of Antiscalants and brine can cause issues when they react with each other. The reaction can cause a change in the physical and chemical structure of the scale solution. Compatibility tests are needed to check that the solution does not precipitate when mixed with formation brines to cause formation damage.
— Thermal Stability Test
For high-temperature reservoir applications, thermal aging tests need to be carried out. This is to make sure that the Antiscalants are stable at the respective temperatures for the expected squeeze lifetime.
— X-Ray Diffraction
X-ray Diffraction (XRD) is a technique used in materials science for determining the atomic and molecular structure of a material. This is commonly used for characterizing scales as well as other oilfield samples.
Scale Issue Study Services
Our Oilfield Scale Study and Deposits Analysis services address scale problems and can incorporate strategies for prevention, prediction and remediation. While scale deposition is not a new occurrence, it has growing implications for the industry as it moves into the future. Services we deliver include:
- To identify any potential problems related to condensate and gas flow during the production, from reservoir to reception facilities (surface manifold)
- Determination of the extent and likelihood of any mineral scale deposition via a combination of computer modeling and laboratory evaluations, including identifications of an effective chemical treatment program, where required.
- Develop operational procedures in order to eliminate or mitigate the potential scale or other observed flow assurance issue.
