Abstract

A hydrate inhibitor comprising a boronic acid moiety and associated methods and compositions.

Claims (13)

1. A method comprising:

providing a hydrate inhibitor composition comprising a boronic hydrate inhibitor and a carrier fluid;

injecting the hydrate inhibitor composition into a well or pipeline in an amount sufficient to prevent formation of agglomerates of hydrates,

wherein the boronic hydrate inhibitor has the following chemical structure:

wherein R is selected from the group consisting of an alkyl chain, an arene group, an aryl chain, an arylalkyl chain, an alkylaryl chain, a polycyclic aromatic group, a polycyclic group, and an aromatic group; and

preventing formation of agglomerates of hydrates in the well or pipeline.

2. The method of claim 1 , wherein the well or pipeline is a subsea well or pipeline.

3. The method of claim 1 , wherein the carrier fluid is selected from the group consisting of water, methanol, glycol, glycol ethers, toluene, naphtha, a terpene, and combinations thereof.

4. The method of claim 1 , wherein the boronic hydrate inhibitor comprises naphthalene-1-boronic acid.

5. The method of claim 1 , wherein the boronic hydrate inhibitor comprises pyrene-1-boronic acid.

6. The method of claim 1 , wherein the boronic hydrate inhibitor comprises methyl butyl boronic acid.

7. The method of claim 1 , wherein the boronic hydrate inhibitor comprises (2-phenylethyl) boronic acid.

8. The method of claim 1 , wherein the hydrate inhibitor is present in the boronic hydrate inhibitor composition in an amount in the range of from 20 wt. % to 90 wt. %.
