Using widely distributed and cheap lignite as starting material, humic acid was modified by octadecylamine, and a new kind of humic acid acetamide was prepared. The optimal reaction conditions of the humic acid acetamide polymer were obtained through laboratory tests as follow: the ratio of of humic acid and octadecylamine was 1:1.5, the reaction temperature was 150 °C, and the reaction time was 16~18 h. The new product was characterized by IR, and the results showed that this substituted-ammonium humic acid was successfully prepared by reacting parts of carboxyl group of humic acid with octadecylamine. HTHP filtration experiments demonstrated that the substituted-ammonium humic acid had good fluid loss properties. As a result, this substituted-ammonium humic acid polymer is an excellent fluid loss additive, and it could meet the requirement of drilling operation under extreme condition.

Fluid Loss Additive

Humic acid acetamide compounds with lipophilic property could dissolve or disperse in oil phase, so they were an important fluid loss additive for oil-based drilling fluids. Compared with water-soluble humic acid derivatives, the fluid loss-reducing mechanism of them was different. With analyzing the mechanism of increasing the flow resistance of liquid phase, bridging plugging, plugging pore and improving the quality of mudcake, the fluid loss-reducing mechanism of lipophilic humic acid acetamide compounds is investigated.

Abstract The hydrocarbon extraction and exploitation using state-of-the-art modern drilling technologies urge the use of biodegradable, environment-friendly drilling fluid and drilling fluid additives to protect the environment and humanity. As more environmental laws are enacted and new safety rules implemented to oust the usage of toxic chemicals as fluid additives, it becomes inevitable that we re-evaluate our choice of drilling fluid additives. Drilling fluids and its additives play a crucial role in drilling operations as well as project costing; hence, it is needed that we develop cost-effective environment-friendly drilling fluid additives that meet the requirements for smooth functioning in geologically complex scenarios as well as have a minimal ecological impact. The current research work demonstrates key outcomes of investigations carried out on the formulation of a sustainable drilling fluid system, where groundnut husk is used as a fluid loss additive and a rheological modifier having no toxicity and high biodegradability. Cellulose was generated from groundnut husk at two varying particle sizes using mesh analysis, which was then compared with the commercially available PAC at different concentrations to validate its properties as a comparable fluid loss retarder additive as well as a rheological modifier. In the present work, various controlling characteristics of proposed groundnut husk additive are discussed, where comparison at different concentrations with a commercially available additive, PAC, is also validated. The API filtration losses demonstrated by the (63–74) µm and the (250–297) µm proposed additive showed a decrease of 91.88% and 82.31%, respectively, from the base mud at 4% concentration. The proposed husk additives acted as a filtrate retarder additive without much deviation from base rheology and with considerably higher pH than the base mud. This investigation indicates that the proposed fluid loss additive and rheological modifier can minimize the environmental hazards and have proved to be a cost-effective eco-friendly alternative in this challenging phase of the hydrocarbon exploration industry.

Bio-based polyol polyesters are biodegradable elastomers having potential utility in soft tissue engineering. This class of polymers can serve a wide range of biomedical applications. Materials based on these polymers are inherently susceptible to degradation during the period of implantation. Factors that influence the physicochemical properties of polyol polyesters might be useful in achieving a balance between durability and biodegradability. The characterization of these polyol polyesters, together with recent comparative studies involving creative synthesis, mechanical testing, and degradation, have revealed many of their molecular-level differences. The impact of the polyol component on the properties of these bio-based polyesters and the optimal reaction conditions for their synthesis are only now beginning to be resolved. This review describes our current understanding of polyol polyester structural properties as well as a discussion of the more commonly used polyol monomers.
