“…Therefore, it is important to monitor and continuously adjust the viscosity of the drilling fluid during drilling process to achieve the purpose the mud is designed for (Okumo and Isehunwa, 2007). Aside removing cuttings from the well, the mud should be capable of forming a thin seal preventing fluid from entering in to the formation otherwise, it will cause stuck pipe and loss of circulation, an influx or a kick that may graduate to a blowout, formation damage just to mention but few (Igbani et al, 2015).Water based mud has a wide application because it is easy to formulate, environmentally friendly (Dankwa et al, 2018) and while nearly 5-10 % use oil-based muds (Sifferman et al, 2003). The frequent use of water based mud has led to the development of three distinct types; inhibitive; noninhibitive and polymer water based mud (Reza, 2015).…”

Success of any rotary drilling mud is to remove cuttings during drilling process. Viscosity is by far, the most needed property of the drilling fluid to aid it perform its needed task. The viscosity property of the mud helps in well cleaning and also aid in the suspension of drilling cuttings when circulation of the fluid is put on hold. It is important to monitor and continuously adjust the viscosity of the drilling fluid. Cassava flour in controlling viscosity and fluid loss in Water Based Mud (WBM) was investigated in this study. Various mud samples were formulated consisting of different masses of cassava flour (5 g, 15 g, 30 g and 45 g) and an additional one being the control bentonite clay (0 g of cassava flour). Rheological tests were carried out to determine the plastic viscosity, mud density, and gel strength. This investigation showed that increasing the amount of cassava flour in a water based mud increased the viscosity of the mud swelling with exception of 5g cassava flour for the 10secs and 10mins gel strength and mud density.

Drilling oil and gas wells for hydrocarbon exploration involve high fluid loss costs. Minimizing the fluid loss is crucial to the drilling process to preserve the mud's qualities and to avoid formation impairment. Research has shown positive use of carboxymethylcellulose (CMC) and imported bentonite in the formulation of water-based mud to minimize fluid loss, however, increases the operating cost while the local bentonite has shown increased filtration losses. The aim of this study is to evaluate the rheological and filtration properties of water-based muds formulated using unmodified and modified starch with ethylenediaminetetraacetic acid (EDTA-DSD), a locally sourced material as a fluid loss additive and hyperdrill as a viscosifier at low-pressure low temperature (LPLT) and high-pressure high temperature (HPHT) conditions, and their performances were compared with CMC as reference fluid loss additives. Thermogravimetric Analysis (TGA), Scanning Electron Microscope (SEM) were harnessed to study the properties of these starches while the starch modification was achieved through acetylation and carboxymethylation. Full-set measurements of laboratory tests were conducted to evaluate the influence of adding 0.5-2g of CMC, unmodified and modified starch to the mud samples respectively, and measurements were taken using mud balance, viscometer, low-pressure and low-temperature filter press, chemical titration, and other standard drilling fluid laboratory equipment as recommended by API. Result showed that Plastic viscosity, PV for unmodified starches ranged from 14-17cP, Yield point, YP ranged from 25-31lb. /100ft2,filtrate volume ranges from 18-31ml at LPLT and 30-43ml at HPHT while PV for modified starches ranged from 14-15cp, YP ranged from 27-31lb. /100ft2, filtrate volume ranges from 17-31ml at 100psi and 19-43ml at 500psi of pressure. Experimental results indicate that the filtrate volume and cake thickness compare favorably with CMC, has the capacity to withstand HPHT conditions and are within the American Petroleum Institute specification for water-based mud. Thus, demonstrate its suitability for current and future exploration and exploitation of oil and gas resources.
