“…The acrylic-lignosulfonate was effective as dispersant seawater drilling fluid (Kelley 1983). Moreover, grafting of acrylamide onto lignosulfonate with redox H2O2/CaCl2 and potassium persulfate at 30ºC was successfully used in the salty water-based drilling fluids (Abdollahia et al 2018). Ultrasound-assisted sulfonation process more effective than conventional heating, such as shorter time of reaction in lower temperature and higher yield of lignosulfonate (Ma'ruf et al 2018).…”

Lignin is the second most naturally abundant biopolymer in the cell wall of lignocellulosic compound (15-35%) after cellulose.Lignin can be generated in massive amounts as by-products in biorefineries and pulp and paper industries through differing processes. Most lignin is utilized as generating energy and has always been treated as waste. Due to the high amount of phenolic compounds in lignin, it is considered as a potential material for various polymers, building blocks, and biomaterials production. Even though lignin can be utilized in the form of isolated lignin directly, the modification of lignin can increase the wide range of lignin applications. Lignin-based copolymers and modified lignin show better miscibility with another polymeric matrix, outstanding to the enhanced performance of such lignin-based polymer composites.This article summarizes the properly updated information of lignin’s potential applications, such as bio-surfactant, active packaging, antimicrobial agent, and supercapacitor.Keywords: active packaging, antimicrobial agent, bio-surfactant, lignin, supercapacitor

“…[ 1–5 ] The application of polymer as an important chemical product has been continuously increasing during the last decades. [ 2,6–11 ] During the polymer flooding process, a series of water‐soluble polymers, such as polyacrylamide or its derivatives, [ 12–15 ] are used to thicken the displacing fluid to extend swept volume, reduce the mobility of the aqueous phase, and accordingly enhance oil production. Furthermore, the adsorption of polymer in the porous media formation reduces the permeability to water, and polymer viscoelasticity is able to enlarge the microscopic sweep efficiency improvement.…”

Partially hydrolyzed polyacrylamide (HPAM) is the most extensively used polymer for enhanced oil recovery due to its accessibility and low cost. However, HPAM shows inadequacies in high mineralization and high‐temperature reservoirs. To solve this problem, a comb‐like polymer with superior salt‐resistance and stability named CHPAM was prepared via direct free‐radical copolymerization of acrylamide (AM) and acrylic acid (AA) with the self‐designed monomer (Acryloyl‐MPEG‐1000). The chemical structures of CHPAM and monomers were characterized by Fourier transform infrared spectroscopy (FT‐IR) and nuclear magnetic resonance spectroscopy (NMR). Static light scattering (SLS) was adopted to measure the molecular weights of CHPAM and HPAM. The solution properties of CHPAM and HPAM were comparatively studied. It was found that CHPAM showed better thermal‐salt stability and salt‐resistance than HPAM, especially in Ca2+ solution. This work paves a new way for the preparation of novel polymers.

“…Different types of drilling fluids are suitable for different drilling environments. WBDFs is the most widely used drilling fluids in drilling operations owing to its relatively low cost, wide source of raw materials, and mild environmental pollution 11–13 . WBDFs is a multiphase dispersion system composed of bentonite (Na‐BT), water (or brine), various chemical treatment agents, weighting materials and drilling cuttings 14,15 .…”

Synthetic copolymers as filtrate reducers for water‐based drilling fluids (WBDFs) are difficult to meet the needs of drilling engineering only by changing the type and proportion of functional groups of copolymers, especially under ultra‐high temperature and high salinity. In this study, an anionic terpolymer (named PSDI) with rigid side chain was synthesized using sodium p‐styrenesulfonate, N, N‐Dimethylacrylamide, and itaconic acid by free‐radical copolymerization. The chemical structure of PSDI was characterized by Fourier transform infrared spectroscopy and 1H‐NMR spectrum. The high‐temperature/high‐pressure filtration loss (FLHTHP) and the American Petroleum Institute filtration loss (FLAPI) of the WBDFs containing 1.5 wt/vol% PSDI were 35.0 and 17.0 ml after thermal rolling at 240°C for 16 h, respectively. The FLHTHP and FLAPI of the WBDFs containing saturated NaCl were with control of 60.0 and 12.0 ml. The FLAPI of WBDFs containing 1.5 wt/vol% CaCl2 reduced to 6.0 ml. Results indicate that the addition of PSDI can improve the anti‐high‐temperature performance and resistance to salt and calcium contamination of WBDFs. Results of rheological tests through fitting four rheological models suggest that rheological parameters can be improved as a result of forming the spatial network structure between the PSDI and bentonite flakes.
