“…The addition of corrosion inhibitors to aggressive acids is one of the most effective means to retard metal corrosion during oil-well acidizing, acid pickling, and acid cleaning in the oil and gas industry. [1][2][3][4][5][6] Typically, these corrosion inhibitors are organic compounds such as surfactants and ionic liquids. [7] Surfactants are a category of traditional and efficient inhibitors that attach to the metal surface by hydrophilic heads and establish a compact protective layer containing hydrophobic tails.…”

A comparative study on 1-dodecyl-2,3-dimethylimidazolium chloride ([DDMIM]Cl) and 1-benzyl-3-dodecyl-2-methylimidazol-1-ium chloride ([BDMIM]Cl) as corrosion inhibitors for N80 steel in a 15% hydrochloric acid solution was performed by surface tension tests, electrochemical measurements, weight loss, scanning electron microscopy, atomic force microscopy, and theoretical calculations. The experimental results confirm that [DDMIM]Cl and [BDMIM]Cl act as mixed-type inhibitors. The adsorption of both inhibitors on the N80 steel surface obeys the Langmuir adsorption isotherm, and [BDMIM]Cl exhibits better inhibitive performance, lower critical micelle concentration (CMC), and a lower ratio of saturation adsorption concentration on the steel surface to its own CMC than [DDMIM]Cl. The results of theoretical calculations reveal that the electron-donating/accepting capacities and hydrophobicity of the benzyl substituent in the imidazole ring are essential for preventing steel corrosion in acid media.

“…Due to the reducing capabilities of the CO, retardation of tubular corrosion (Cabello, 2013) in the presence of CO 2 and water warrants additional investigation. Swelling clays (smectite, smectite/ illite, montmorillonite, and bentonite) have significant amounts of ferric oxides/hydroxides both interlayer and especially on clay margins.…”

Achieving maximum oil recovery utilizing CO 2 has limitations when operating at, or very close, to the Minimum Miscibility Pressure (MMP) of the CO 2 in the oil. A modular source of CO 2 would allow Enhanced Oil Recovery (EOR) flooding of ЉstrandedЉ and shallow reservoirs. Unfortunately, modular sources of CO 2 production often include CO and N 2 mixed with the CO 2 . Thus, testing for EOR application of a mixed gas-containing CO 2 , N 2 , and CO was initiated.Bench scale testing using Rising Bubble Apparatus (RBA), Slim Tubes, and linear core flood have been conducted on oils ranging from 16-42°gravities having viscosities of 0.5-280 cp. All tests were conducted at reservoir temperatures and pressures. CO, being a strong reducing agent, was further tested on reservoir rock containing swelling clays with hydrated ferric hydroxides. Due to the apparent reduction of the ferric hydroxide, and the liberation of its water of hydration, an increase in matrix permeability and clay stabilization, was observed.For most oils tested, the CO 2 /CO mixture increased rate of oil recovery by 2-3X, using only 50-60% as much gas/bo as compared to pure CO 2 . Recovery factors of 80%, at immiscible pressures 30-40% below CO 2 MMP, were achieved. Addition of 15% N 2 (v/v) to the CO 2 /CO mixture did not impair oil recovery. Interfacial testing (IFT) of oils, using pure CO, demonstrated a lowering of the IFT. RBA testing of asphaltine-rich heavy oils has shown that a mixture of CO 2 /CO dissolves into the oil at a far faster rate than either CO 2 or CO individually and faster than the sum of both individual gases. A similar test using non-asphaltine type oils did not display this unique characteristic. Slim tube testing suggests that CO facilitates the mobilization of asphaltine-rich heavy oils and lowers viscosity. A linear corefloods of a reservoir containing 5% smectite ϩ illite/smectite ϩ and chlorite demonstrated a 275% increase in matrix permeability. Packed column tests, containing quartz sand and bentonite, demonstrated up to 300-900% increase in permeability in the presence of CO.Thus a method to recover oil faster, from stranded reservoirs, at pressures below MMP, using significantly less gas, appears possible. In addition the use of CO, either alone or in combination with CO 2 and/or N 2 , has been shown to increase matrix permeability. Such a gas mixture may be beneficial to achieving low pressure EOR from shallow, ЉstrandedЉ reservoirs, non-conventional shale oil reservoirs, and viscous, heavy oil reservoirs at low temperatures. Incorporation of CO, or CO 2 /CO, in a frac fluid, or alternately as a post frac cleanup for shale oil and gas applications appears to warrant investigation.

“…trans -Cinnamaldehyde (CA) is one of the α-, β-unsaturated aldehydes, which can be extracted from cassia bark [14]. Cabello et al [15] evaluated the corrosion inhibition effect of CA allied with carbon monoxide for high–nickel and –iron alloys in HCl solution at high pressure and temperature, and pointed out that a thin polymerized film could be formed on the metal surface to retard the corrosion under an extreme environment. Avdeev and co-workers [16] employed a series of unsaturated aldehydes as the inhibitors for corrosion retardation of mild steel in HCl and H 2 SO 4 media.…”

Constructing molecular assembly between a soluble cyclodextrin polymer (SCDP) and an anticorrosive component is conducive to increasing the availability of a corrosion inhibitor with low molecular polarity in aqueous solution. The SCDP was prepared via the weak crosslinking effect of glutaraldehyde using β-cyclodextrin as the subunit, whose structure was confirmed by proton nuclear magnetic resonance spectra (1H NMR), X-ray diffraction and morphology. An assembly between SCDP (host) and trans-cinnamaldehyde (guest, CA) was constructed, and the intermolecular interactions were disclosed by Fourier transform infrared spectra (FTIR). The corrosion inhibition of SCDP/CA assembly for mild steel in 3.5% NaCl solution was assessed through electrochemical and surface analyses. 1H NMR results showed that exterior hydroxyls of β-cyclodextrin were the active sites for crosslinking. Hydrogen bonds might be the binding force between SCDP and CA according to FTIR analyses. Electrochemical measurements revealed that SCDP/CA assembly could suppress both cathodic and anodic reactions and enhance the polarization impedance for mild steel in the corrosive medium with a maximum efficiency of 92.2% at 30 °C. Surface analyses showed that CA molecules could be released from the assembly followed by the energy competition mechanism, and solely adsorb on the steel surface in parallel form, which was further evidenced by theoretical modeling.
