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.

使用最先进的现代钻井技术开采和开采碳氢化合物，促使人们使用可生物降解，环保的钻井液和钻井液添加剂来保护环境和人类。随着越来越多的环境法律的颁布和新安全规则的实施以驱除有毒化学物质作为流体添加剂的使用，我们不可避免地要重新评估我们对钻井液添加剂的选择。钻井液及其添加剂在钻井作业和项目成本核算中起着至关重要的作用。因此，我们需要开发经济高效的环保型钻井液添加剂，以满足在地质复杂情况下的平稳运行以及对生态的影响最小的要求。当前的研究工作证明了对可持续钻井液系统配方进行研究的主要成果，其中花生壳用作失水添加剂和流变改性剂，无毒性和高生物降解性。纤维素是通过使用网状分析从花生壳中以两种不同的粒径生成的，然后将其与不同浓度的市售PAC进行比较，以验证其作为可比的减水阻滞剂和流变改性剂的性能。在当前的工作中，讨论了提出的花生壳添加剂的各种控制特性，其中还验证了在不同浓度下与市售添加剂PAC的比较。建议的添加剂（63–74）µm和建议的添加剂（250–297）µm证明API过滤损失分别比浓度为4％的基础泥减少了91.88％和82.31％。所提出的果壳添加剂用作滤液抑制剂，而与基础流变没有太大的偏差，并且具有比基础泥浆高得多的pH。这项研究表明，拟议的降滤失添加剂和流变改性剂可以最大程度地减少对环境的危害，并已证明是在碳氢化合物勘探行业这一充满挑战的阶段中具有成本效益的环保替代品。所提出的果壳添加剂用作滤液抑制剂，而与基础流变没有太大的偏差，并且具有比基础泥浆高得多的pH。这项研究表明，拟议的降滤失添加剂和流变改性剂可以最大程度地减少对环境的危害，并已证明是在碳氢化合物勘探行业这一充满挑战的阶段中具有成本效益的环保替代品。所提出的果壳添加剂起着滤液缓凝剂的作用，而与基础流变性没有太大的偏差，并且具有比基础泥浆高得多的pH值。这项研究表明，拟议的降滤失添加剂和流变改性剂可以最大程度地减少对环境的危害，并已证明是在碳氢化合物勘探行业这一充满挑战的阶段中具有成本效益的环保替代品。
