With the increase in energy demand, deeper wells drilling is one of the solutions to fulfill the energy demand, which demands specialized drilling mud formulation. These muds are composed of thermally stable materials that can sustain in high-temperature conditions. Biopolymers are widely used out of various mud additives for improving the rheology and filtration characteristics of mud. Owing to the high temperature and poor thermal stability of such additives, these additives lose their primary functions, resulting in the nonproductive time and irreversible problems. The book chapter highlights the uses of water-based mud, its limitations, and the degradation of biopolymers. Various additives’ significance and susceptibility in harsh borehole conditions have been discussed. The existing additives used for the rheological and filtration characteristics improvements and their shortcomings are presented. Furthermore, the field applications of native and modified polymeric-based mud formulations have been further examined and presented.

“…developed PERFORMAX, a high-performance water-based drilling fluid system for deepwater drilling, in which the filter loss reducer MAX-TROL is a sulfonated resin that acts as a high-temperature and high-pressure filter loss reducer through its own plugging effect. CNOOC has introduced a soil-phase free, strongly inhibited, high performance deepwater water-based drilling fluid system HEM, which was mainly developed by Jiansheng Luo and Huike Li [9] . The filtration loss reducer PF-FLOTRO is a kind of temperature-resistant starch, which reduces the filtration loss by increasing viscosity and lifting cut.…”

In addition to flat rheology to deal with the wellbore stabilization problem caused by narrow safety density window when drilling deepwater wells, upgrading the mud cake quality by fluid loss reducer and plugging to stabilize the wellbore is also an important measure to deal with this problem. For the existing fluid loss reducers for deepwater water-based drilling fluids, it is difficult to balance the plugging performance. In this study, a cationic micro-crosslinking polymer was synthesized as a fluid loss reducer by reversed-phase emulsion polymerization. N-isopropylacrylamide (NIPAM) and acrylamide (AM) were chosen as the main body of the synthesis to enhance the hydrophilicity of the products. Methacryloyloxyethyl trimethyl ammonium chloride (DMC) was selected to provide cationic groups to enhance the residency of the products in the formation. The molecular structure of ENAD was characterized using infrared spectroscopy (FT-IR), nuclear magnetic resonance hydrogen spectroscopy (NMR) and X-ray photoelectron spectroscopy (XPS), and the molecular structure of the product was as expected. The thermal stability of ENAD was analyzed by TGA, and the initial thermal decomposition temperature was 283 °C. The filtration effect of ENAD in BF under different media was evaluated. The experimental results show that ENAD can withstand temperature up to 150°C and has good filtration performance. 16h after aging at 150°C, the API filtration loss (FLAPI) is 8.8mL, the sand bed intrusion depth is 4.4cm, the high temperature and high pressure filtration loss (FLHTHP) is 32mL, the high temperature and high pressure filtration loss of plugging 10μm sand disc is 92mL. After comparing with sulfonated asphalt (FT), it is found that ENAD has better filtration performance. It is found that ENAD has better performance in reducing filtration loss. The mode of interaction between ENAD and the formation and its own mechanism of filtration loss reduction were analyzed by zeta potential analysis and SEM. With the increase of ENAD addition, the absolute values of zeta potential of BF before and after aging decreased from 48.7 and 32.1 to 43.3 and 27.1, respectively. ENAD enhances the interaction force with bentonite particles through its own adsorption properties. The strength of the mud cake is further strengthened by thermal deformation properties. It also enhances the force between the polymer and the formation through electrostatic gravitational adsorption, which further enhances the retention capacity of the polymer in the formation. Compared with conventional fluid loss reducers, ENAD has superior filtration effect and can be used as a fluid loss reducer for deepwater water-based drilling fluids.

“…Likewise, formulations of drilling fluids play an important role in drilling within HPHT environments. Therefore, oil-based drilling fluids (OBDF) have been repeatedly used in HPHT drilling fluid systems, where they have been shown to be effective in shale drilling in HPHT downhole environments [23]. However, OBDF is toxic for marine species [24] and involves a high cost [25] because it is mostly made up of diesel oil [26].…”

Nanomaterial-Based Drilling Fluids for Exploitation of Unconventional Reservoirs: A Review

et al. 2020

The world’s energy demand is steadily increasing where it has now become difficult for conventional hydrocarbon reservoir to meet levels of demand. Therefore, oil and gas companies are seeking novel ways to exploit and unlock the potential of unconventional resources. These resources include tight gas reservoirs, tight sandstone oil, oil and gas shales reservoirs, and high pressure high temperature (HPHT) wells. Drilling of HPHT wells and shale reservoirs has become more widespread in the global petroleum and natural gas industry. There is a current need to extend robust techniques beyond costly drilling and completion jobs, with the potential for exponential expansion. Drilling fluids and their additives are being customized in order to cater for HPHT well drilling issues. Certain conventional additives, e.g., filtrate loss additives, viscosifier additives, shale inhibitor, and shale stabilizer additives are not suitable in the HPHT environment, where they are consequently inappropriate for shale drilling. A better understanding of the selection of drilling fluids and additives for hydrocarbon water-sensitive reservoirs within HPHT environments can be achieved by identifying the challenges in conventional drilling fluids technology and their replacement with eco-friendly, cheaper, and multi-functional valuable products. In this regard, several laboratory-scale literatures have reported that nanomaterial has improved the properties of drilling fluids in the HPHT environment. This review critically evaluates nanomaterial utilization for improvement of rheological properties, filtrate loss, viscosity, and clay- and shale-inhibition at increasing temperature and pressures during the exploitation of hydrocarbons. The performance and potential of nanomaterials, which influence the nature of drilling fluid and its multi-benefits, is rarely reviewed in technical literature of water-based drilling fluid systems. Moreover, this review presented case studies of two HPHT fields and one HPHT basin, and compared their drilling fluid program for optimum selection of drilling fluid in HPHT environment.
