“…Soric and Heier [27,28] synthesized a new generation of high temperature fluid loss additive with temperature resistance up to 230 • C, using vinyl amine (VA) and vinyl sulfonic acid (VS) as the main reaction monomers. Rupinski et al (2009) studied the influence of modified starch and their blends with tylose as protective agents in the filtration of drilling fluids, as well as replacement of tylose by modified starch, were investigated [29]. Dias et al (2015) investigated the potential of using starch derivatives modified with vinyl esters from fatty acids, as additives to control filtrate in invert-emulsion (W/O) drilling fluids [30].…”

During drilling in deep shale gas reservoirs, drilling fluid losses, hole wall collapses, and additional problems occur frequently due to the development of natural fractures in the shale formation, resulting in a high number of engineering accidents such as drilling fluid leaks, sticking, mud packings, and buried drilling tools. Moreover, the horizontal section of horizontal well is long (about 1500 m), and the problems of friction, rock carrying, and reservoir pollution are extremely prominent. The performance of drilling fluids directly affects drilling efficiency, the rate of engineering accidents, and the reservoir protection effect. In order to overcome the problems of high filtration in deep shale formations, collapse of borehole walls, sticking of pipes, mud inclusions, etc., optimization studies of water-based drilling fluid systems have been conducted with the primary purpose of controlling the rheology and water loss of drilling fluid. The experimental evaluation of the adsorption characteristics of “KCl + polyamine” anti-collapse inhibitor on the surface of clay particles and its influence on the morphology of bentonite was carried out, and the mechanism of inhibiting clay mineral hydration expansion was discussed. The idea of controlling the rheology and water loss of drilling fluid with high temperature resistant modified starch and strengthening the inhibition performance of drilling fluid with “KCl + polyamine” was put forward, and a high temperature-resistant modified starch polyamine anti-sloughing drilling fluid system with stable performance and strong plugging and strong inhibition was optimized. The temperature resistance of the optimized water-based drilling fluid system can reach 180 °C. Applied to on-site drilling of deep shale gas horizontal wells, it effectively reduces the rate of complex accidents such as sticking, mud bagging, and reaming that occur when resistance is encountered during shale formation drilling. The time for a single well to trip when encountering resistance decreases from 2–3 d in the early stages to 3–10 h. The re-use rate of the second spudded slurry is 100 percent, significantly reducing the rate of complex drilling accidents and saving drilling costs. It firmly supports the optimal and rapid construction of deep shale gas horizontal wells.

“…Starch is mostly used as effective colloids, because of its ability to decrease fluid loss and increase the viscosity of drilling fluids. These are caused by its swelling capacity which increases its volume due to free space water absorption (Rupinski et al, 2009). Starch contains amylose and amylopectin polysaccharides, the amylose in starch swells up and helps in controlling fluid loss.…”

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.
