Some examples of producing water-based drilling fluids including ecofriendly lubricating additives are described. A raw material oil including fatty acids with a short chain alcohol is esterified in the presence of a catalyst to produce alkyl ester products and triglycerides. The alkyl ester products are washed and heated to remove any residual water or the short chain alcohol. A first quantity of the alkyl ester products is mixed with a second quantity of a water-based wellbore drilling fluid. 本发明描述了制备包含生态友好的润滑添加剂的水基钻探液的些实例。用短链醇将包含脂肪酸的原料油在催化剂的存在下酯化，以制备烷基酯产物和甘油三酯。洗涤烷基酯产物并将其加热以移除任何残余的水或短链醇。将第量的烷基酯产物与第二量的水基井眼钻探液混合。
