Scale and corrosion inhibitors are commonly used in many oil and gas production systems to prevent inorganic deposition and to protect asset integrity. Scale inhibitor products are based on organic compounds with phosphate or carboxylic functional groups such as amino phosphonates, phosphate esters, phosphino polymers, polycarboxylate and polysulfonates,1 as shown in Figure 1. These anionic groups have strong affinity to alkaline earth cations and can adsorb on the active growth sites of scale crystal (Figure 2), resulting in stopping or delaying the scale formation process.

Metal-carbonate scales are a double-edged sword for upstream oil and gas production engineering. On one hand, many of these scales can lead to serious setbacks if untreated, such as production interruption. One common example is calcite scale deposition on production tubing.

This production asset located in the deep-water offshore Brazil, producing heavy oil in the range of 16 to 24 oAPI. Mudline caisson separators with electrical submersible pumps (ESPs) are used to process fluids from multiple wells and boost them to the receiving floating production, storage, and offloading (FPSO) vessel(1). There are significant flow-assurance and corrosion challenges in operating the asset. One of the challenges is the production fields have limited subsea umbilical, necessitate the use of
multifunctional products to maintain the field’s integrity and mitigate any flow assurance and scale issues.

F22 is a low alloy steel that typically contains 12% Carbon, 2.25% Chromium, and 1.0% Molybdenum1. This steel has been widely used in oil production systems, especially in well head design and construction. As a low alloy steel, F22 can be corroded by oilfield chemicals under certain circumstances. For example, it was observed in the Gulf of Mexico that typical scale inhibitor chemistries caused severe corrosion on F22.

Mineral scale deposition is one of the major flow assurance issues for the oil and gas industry. When an oil or gas well produces water, there is the possibility that scale could form either by the mixing of incompatible waters forming oversaturated brine or by direct precipitation of the water that occurs naturally in reservoirs due to the changes in pressure, temperature, or pH. Scale inhibitors are commonly used to prevent mineral scale formation during oil and gas production and mitigate this flow assurance issue.

Mineral scale deposition and pipeline corrosion are two of the most common challenges that require chemical treatment in oil wells. Combination products including scale inhibitor (SI), corrosion inhibitor (CI) packages, surfactants, and other chemical additives are well accepted as an integrated solution to flow assurance and asset integrity problems. In this work, a case study in the Permian Basin field demonstrates a certain type of combination product exhibiting lower performance than expected. The raw material interference on the scale inhibitors was investigated and presented with detailed laboratory data. A series of laboratory tests were conducted to investigate the impacts on performance from the chemicals in the combination product. In the dynamic tube blocking test, the phosphonate-based SI shows much weaker performance in the presence of certain active CI components, while other raw materials (surfactants and quaternary amine) had a minor effect. Further bottle tests revealed a calcite inhibition drop from complete inhibition to 30% and 40% inhibition in the two phosphonate-based SI chemistries in the presence of the active component, respectively. In the additional barite inhibition tests, no significant impact on the SI performance was observed. Contrary to the previous literature reports about common CI chemicals, this active component expressed significantly adverse impacts on the SI performance for calcite prevention. This study demonstrates a root cause analysis for the adverse effect of certain active CI components on the scale prevention and suggests the impact of the CI package on SI should be carefully investigated in the product selection. A thorough evaluation of combination product performance is recommended before the field application.

The formation of mineral scales is one of the most problematic threats to the oil and gas operations which can lead to loss of production, increased lifting costs and assets deterioration.1 Mineral scales can precipitate at any locations within an oil and gas production system and create blockage in perforations, production tubulars, pumps, and surface equipment. The formation of scale deposits can be attributed to the mixing of incompatible waters from different production zones or physical and chemical condition changes associated with produced water transporting from reservoir to wellhead and further to processing facilities.

Seawater injection is commonly utilized for offshore wells to maintain or increase oil production; however, treatment for seawater before injection is always necessary to reduce or remove bacteria, dissolved oxygen, sulfate, and other impurities. Seawater typically has >2000 mg/L sulfate. Without proper sulfate removal, such high levels of sulfate can cause not only barium sulfate, strontium sulfate, and calcium sulfate scales, but also reservoir souring and H2S corrosion in the presence of sulfate reducing bacteria (SRB). Therefore, sulfate removal from seawater is critical before seawater injection into reservoir.
