Abstract
The present disclosure relates to a system including: a wellhead including: a landing base; a wellhead pipe, wherein the wellhead pipe extends from the landing base; and a surface casing, wherein the surface casing at least partially surrounds the wellhead pipe; a hydrophobic sand pack including a hydrophobic sand, the hydrophobic sand pack at least partially surrounding: the landing base, the wellhead pipe, the surface casing, or any combination thereof.
Claims23
A system comprising:
- a wellhead comprising:
- a landing base;
- a wellhead pipe, wherein the wellhead pipe extends from the landing base;
- and
- a surface casing, wherein the surface casing at least partially surrounds the wellhead pipe;
- a hydrophobic sand pack comprising a hydrophobic sand, the hydrophobic sand pack at least partially surrounding:
