Technology Wellhead leaks often come from void sealing leaks, flange sealing leaks or neck seal leaks. Squeezing ERS or VB sealant into void space can cure wellhead leaks. Sealant is squeezed into void space and forced to penetrate into sealing leaks channels. Once it crosslinks, it will permanently shut off the leaks. In case ERS sealants cure the leaks, wellhead may be difficult to dismantle. In case VB cures the leaks, future wellhead dismantlement will be easy.
