“…For copolymer SX-1 (Figure 8, red), the characteristic bands include the primary amide NH2 asymmetric stretching at 3353 cm −1 , and the symmetric stretching band of NH2 at 3159 cm −1 [25,26]. In the spectrum of the Na-MMT/SX-1 composite material (Figure 8, blue) there occurs an absorption band at 1618 cm −1 , assigned to the primary amide C=O stretching (CONH2), while the absorption band at 1400 cm −1 corresponds to COO-stretching, which suggests the successful incorporation of SX-1 into Na-MMT [27][28][29]. There are quaternary amine and amide as well as alcohol functionalities in SX-1; adsorption is expected to take place based on the ion-dipole interactions between the polar alcohol groups and the exchangeable cations of shale, as well as H-bonding, van der Waals interactions and entropy effects [30].…”

In this work, a novel low molecular weight zwitterionic copolymer for improving wellbore stability, which is expected to be an alternative to the current shale inhibitors, was obtained by copolymerization of tris hydroxyethyl allyl ammonium bromide (THAAB), 2-acrylamido-2- methyl propane sulfonic acid (AMPS) and acrylamide (AM), initiated by a redox initiation system in an aqueous solution. The copolymer, denoted as SX-1, was characterized by FT-IR, TGA-DSC, and GPC. Results demonstrated that the molecular weight of SX-1 was approximately 13,683 g/mol and it displayed temperature resistance up to 225 °C. Regarding the inhibition performance, evaluation experiments showed the hot rolling recovery of a Longmaxi shale sample in 2.0 wt % SX-1 solutions was up to 90.31% after hot rolling for 16 h at 120 °C. The Linear swelling height of Na-MMT artificial core in 2.0 wt % SX-1 solution was just 4.74 mm after 16 h. Methods including particle size analysis, FTIR, XRD, and SEM were utilized to study the inhibition mechanism of SX-1; results demonstrated that SX-1 had entered into the inner layer of sodium montmorillonite (Na-MMT) and adsorbed on the inner surface, and the micro-structure of Na-MMT was successfully changed by SX-1. The particle size of Na-MMT in distilled water was 8.05 μm, and it was observed that its size had increased to 603 μm after the addition of 2.0 wt % of SX-1. Its superior properties make this novel low molecular weight copolymer promising for ensuring wellbore stability, particularly for high temperature wells.

“…For example, Li et al added soybean isolation (6 wt%) into drilling fluid and reduced the filtration rate from 7.5 mL/s to 2.5 mL/s due to the permeability decrease in filter cake [ 99 ]. Through another mechanism, the function of rice husk as fluid loss agents lies in its ability to increase the thickness of filter cake [ 100 ].…”

Polysaccharide biopolymers are biomacromolecules derived from renewable resources with versatile functions including thickening, crosslinking, adsorption, etc. Possessing high efficiency and low cost, they have brought wide applications in all phases of petroleum recovery, from well drilling to wastewater treatment. The biopolymers are generally utilized as additives of fluids or plugging agents, to correct the fluid properties that affect the performance and cost of petroleum recovery. This review focuses on both the characteristics of biopolymers and their utilization in the petroleum recovery process. Research on the synthesis and characterization of polymers, as well as controlling their structures through modification, aims to develop novel recipes of biopolymer treatment with new application realms. The influences of biopolymer in many petroleum recovery cases were also evaluated to permit establishing the correlations between their physicochemical properties and performances. As their performance is heavily affected by the local environment, screening and testing polymers under controlled conditions is the necessary step to guarantee the efficiency and safety of biopolymer treatments.

“…Therefore, there are many research efforts geared towards the utilization of these wastes in oil and gas operation. Adewole and Najimu (2017) investigated the effects date pit additive on water-based drilling fluid. The study involved the effects of date pit chemical compositions, particle size, and date pit concentrations on the fluid density, rheology, filtration and thermal properties of the fluids.…”

Naturally occurring macromolecular materials can be turned to value-added resources for applications in oil and gas production. The use of these materials has become necessary due to the environmental requirements that are associated with the disposal of oilfield chemicals after usage, sustainability of raw materials for producing the chemicals, and the need for reducing the overall cost of hydrocarbon production. This review presents the applications of natural polymers in oilfield operations including drilling, enhanced oil recovery, and water and gas shut-off.
