“…A third intermediate liquid phase labeled microemulsion can also be attained at the so‐called “optimum formulation” when a multivariable expression is satisfied (Forgiarini et al, 2021; Salager et al, 2013, 2019). These characteristic properties turn surfactants into valuable chemicals, finding application in various fields that include the formulation of pharmaceutical and personal care products (Munday, 2000; Salager et al, 2020; Schramm et al, 2003), and in the petroleum, detergents, and food industries (Cristina et al, 2012; Koteich Khatib et al, 2020; Kralova & Sjöblom, 2009). Some natural surfactants even perform critical physiological functions in living organisms (Zasadzinski et al, 2001).…”

This work reviews the use of carbohydrates and their derivatives as renewable raw materials in the production of surfactants. Methods to attain state‐of‐the‐art carbohydrate‐derived surfactants are described. This includes surfactants widely used nowadays and others that have not yet transcended beyond the academic field. Given the abundance of hydroxyl groups in carbohydrates and the considerable quantity of different surfactant structures that can be generated during their synthesis, selectively obtaining a target product represents a challenge. Therefore, this work focuses on the platform chemicals available to synthesize biobased surfactants. The first part of the review comprises a brief introduction of simple and complex carbohydrates to better understand their chemistry. Then, a description of the processes to obtain biobased building blocks derived from carbohydrates according to the National Renewable Energy Laboratory (NREL, USA), and their usefulness in synthesizing surfactants is presented. This provides an organized inventory of the knowledge around the synthesis–production of surfactants from carbohydrate derivatives, emphasizing raw materials that could be inserted into the circular bioeconomy concept. Finally, the current industry trends and the potential role of biobased surfactants around new dioxane regulations are discussed.

“…They are commonly utilised during flooding to aid additional oil recovery by reducing surface tension (Felix et al, 2015;Bashir et al, 2022). Surfactants are also a usual component of stimulation and completion fluids to prevent formation damage or corrosion in the pipelines (Renpu, 2011;Santanna et al, 2012). Petroleum sulfonates have been used and studied for several applications in this industry (Barakat et al, 1983) due to their availability, low cost and ease of manufacture.…”

This paper discusses successful damage remediation performed in more than 10 wells in a mature oil field producing under a developed waterflooding project in Colombia. The primary damage mechanism observed is associated with a detriment to production related to reduced relative permeability caused by wettability preferences.A chemical treatment was proposed that consisted of crude oil with efficient and effective surface active additives, such as microemulsions (MEs) and/or formation mobility modifiers (FMMs) and associative polymers (APs) for a proper diversion. The treatment was proposed as an effective method to restore near-wellbore (NWB) permeability in or through the damaged zone in the formation, resulting in production recovery. All matrix-stimulation treatments were conducted rigless by means of an annulus without affecting the artificial lift method and resulted in a significant time and cost savings.Laboratory data confirmed the ability of the MEs and FMMs to modify interfacial tensions (IFTs) and contact angles. These materials helped promote a change in the degree of wetting of the system, which is dependent on the adhesion tension (the product of the IFT by the cosine of the contact angle). During well treatments, surface pressure spikes during the diversion stages were associated with the arrival of the APs at the perforations and were clearly observed during the development of the treatments, revealing that effective diversion was achieved. Finally, post-stimulation treatment data have shown positive results, confirming the effectiveness of combining these technologies. This paper discusses how the synergy of using surface active additives with diversion technologies can yield productivity increase in mature oil reservoirs and improve the level of sustainability of current field production.
