本レビューは、石油・ガス生産におけるスケール（鉄硫化物、硫酸塩、炭酸塩）の形成メカニズムと、従来型および環境に優しいスケール抑制剤の有効性を包括的に検討する。従来の抑制剤は高い効率を示すが、生分解性や毒性の問題がある。植物抽出物や生分解性ポリマーなどのグリーン抑制剤は、同等の効率（最大100%）を達成し、環境負荷を低減する。将来の研究は、性能と環境適合性のバランスに焦点を当てるべきである。
English
This review examines scale formation mechanisms and inhibitors in oil and gas production, comparing conventional and green alternatives. Green inhibitors from natural sources achieve comparable efficiency (up to 100%) with lower environmental impact. Future research should balance performance and sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の石油・ガス産業や化学メーカーにとって、環境規制に対応したグリーンケミカルの開発は重要。ただし、GX政策との直接的な関連は薄く、エネルギー転換の文脈では間接的な貢献に留まる。
In the global GX context
Globally, the oil and gas sector faces pressure to reduce environmental footprint. Green scale inhibitors offer a pathway to reduce chemical pollution and improve sustainability, aligning with broader ESG goals in the industry.

📄 Abstract（原文）
Chemical scale inhibitors added at substoichiometric concentrations are widely considered the most effective mitigation strategy. This review comprehensively examines the types of scale (iron sulfide, sulfate, and carbonate scales), mechanisms of scale formation (aggregation, nucleation, crystal growth, and agglomeration), and scale inhibition mechanisms including threshold inhibition, crystal modification, chelation, and dispersion. Conventional scale inhibitors, phosphonates (ATMP, HEDP, DTPMP, PBTC), synthetic polymers (polyacrylic acid, polymaleic acid), inorganic inhibitors, and chelating agents (EDTA, DTPA), demonstrate high efficiency but face increasing environmental restrictions due to poor biodegradability, toxicity, and phosphorus induced eutrophication. In response, green scale inhibitors derived from natural sources, plant extracts (fig leaf, olive leaf, pomegranate, aloe vera, clove, cassava, moringa, garlic, neem), biodegradable polymers (polyaspartic acid, polyepoxysuccinate), modified natural polymers (chitosan, pectate, starch phosphate), and natural carboxylic acids (citric acid, maleic acid), have emerged as viable, environmentally friendly alternatives, many achieving inhibition efficiencies comparable to conventional inhibitors (up to 100% in some cases). The review also discusses physical and mechanical scale control methods (fluid conditioning, water softening, magnetic treatment, pigging, jetting, scale-resistant coatings) and analyzes key factors affecting inhibitor performance, including temperature, pH, pressure, ionic strength, inhibitor concentration and molecular structure, exposure time, fluid hydrodynamics, and reservoir heterogeneity. The paper concludes that future research must focus on developing green scale inhibitors that balance high performance, long-term stability under harsh field conditions, complete biodegradability, and cost-effectiveness, while emphasizing that inhibitor selection must be tailored to specific field conditions rather than applying universal solutions.
