1	sapphire rocking cell RCS6	CH4	crude oil	125 mL	50	decane	(3–10)	25 to −5	up to 10	Some oil components (likely resins, and asphaltenes) contribute to the hydrate nucleation in water, oil, and gas systems.	(92)
						surfynol 420
						span 80
2	rocking cell	CO2	crude oil	100 mL	20	methanol	12	– 20 to 40	20	The existence of crude oil in a multiphase system inhibits the production of gas hydrates, leading to a delay in hydrate form.	(79)
						MEG
						NaCl
						KCl
3	rocking cell	CH4	mineral oil 70T		30	NACL	3.5	13 to −5	7	Antiagglomerates aid in the formation of transportable hydrate slurry; however, at low concentrations of AA, temporary hydrate agglomeration was observed.	(80)
						MEG	6.6
4	stainless-steel chamber	CO2	wax content and mineral oil	125 mL	adsorption in water	ASP	3	30 to 20	27	The impact of asphaltenes on hydrate nucleation was more significant than waxes.	(93)
5	pressure cell	CH4	conroe oil	65%	35			4	4.92	The amount of hydrate formed over time increased as the water fraction increased; this increase is most likely extrinsic.	(45)
6	flow loop	CH4	condensate gas + water + diesel oil–water	5 vol %	95	antiagglomerant CAA	2.0	4 and 1	10	Despite the initial water cut, the adopted antiagglomerate may disperse hydrate particles in the fluid phase and the formed.	(82)
				10 vol %	90
				15 vol %	85
				20 vol %	80
				25 vol %	75
7	rocking cell system	CH4	condensate liquid and crude oil	2–7 mL of crude oil	30–80	antiagglomerate	0.2–1	4	10	Thermodynamic inhibition and reduction of AA adsorption on the hydrate surface are two possible effects of salt on AA performance.	(83)
8	HP-mDSC	CH4	vegetable oil	115 g	55	triethylamine	30	20 to −20	25	Some hydrate inhibitors, such as quaternary salts, contain chloride as a counterion, which can cause corrosion.	(40)
						diisocyanate
						PVP
						polyethylene
						glycol
9	rocking cell	CH4	mineral oil 70T	-	60	MEG	6.6	20 to 1	4.5–3.5	Inhibited systems have a higher risk of hydrate agglomeration than noninhibited systems under certain conditions.	(81)
						NACL	3.5
						arquad	0.5
10	rocking cell	CH4	crude oil	0%	100	Luvicap-Bio		20 to −60	10	The percentage of the liquid hydrocarbon phase increases, and there is a clear inhibitory impact on hydrate formation.	(77)
