Influence of the concentrations of xanthan gum, hydroxypropyl starch and potassium chloride on the flow properties of drilling fluid formulations

Abstract

Drilling operation of oil wells involves high costs and risks. With recent discoveries of deeper reservoirs and difficult to access, there was an increase in the number of horizontal wells drilled and far-reaching, and, thereat, new challenges with operational problems. Fluids, or muds, drilling are essential to the well drilling process, confirming the need to study and find physical, rheological, and filtration properties, appropriate to the complexities in each section and the drilling stage. Optimized formulation is the one that comprises a safe operation, mitigation of operational problems, environmental protection, low cost, and high productivity. Thus, this paper offers the study of the rheological properties, and determination of filtrate volume, of the aqueous base fluid formulations, developed with polymeric additives. A high performance formulation, presenting technical-economical feasibility for drilling operations, was achieved using 0.43% m/v of viscosifier (xanthan gun), 0.57% m/v of filtrate controller (hydroxypropyl starch) and 4.57% m/v of clay swelling inhibitor (KCl)

RETRACTED: On Improving Water-Based Drilling Mud Swelling Control Using Modified Poly(Vinyl Alcohol)s

“…12 Another assessment of the most used polymer, xanthan gum (XG), by Alves et al ( 2019) on the XG influence on flow properties of a water-based drilling fluid shows XG increasing content (0.15% to 0.55%) rise in the plastic viscosity and yield point by 28% and 40%, respectfully. 13 Such observations about fluid loss control and rheological improvement by several research studies 14−18 have increased the global drilling polymer industry, which is currently reporting a global market forecast of USD 2,705.4 million by 2030. 19 Many studies have also confirmed that polymers provide thermal stability.…”

Correlation between Methods to Determine Total Oil and Grease in Synthetic Oily Water Using Heavy Oil: Gravimetry vs Fluorimetry

“…To run the oil and gas industry, different expertise areas are involved. , For example, studies related to drilling, − completion, hydraulic fracturing, , enhanced oil recovery, , acidizing, organic deposition inhibition, − inorganic deposition inhibition, , and the demulsification process − are relevant to optimize the oil production. Nevertheless, the quality of water that is discarded or reinjected plays an important role not only in the oil business as a whole but also in the issues related to environmental aspects. − Moreover, the treatment of oil-spilled seawater is a challenge around the world, adding motivation to the research on oil–water separation. − …”
