Chevron China

The Problem

2 Toolstrings lost in a 4-1/2" well. Location was a populated area, SITHP 4500psi, 14.5% (145,000ppm) H2S, with a serious hydrate problem.

Resolution

BDWS engaged when the second wire + fish was left in the well just below the tubing hanger. Based on the well history, BDWS worked with the client to prepare a fishing program. The program was agreed and specialized fishing tools were immediately prepared for 'hot shot'.

BDWS fishing and well control expert recovered all wire + fish. BDWS also supervised coiled tubing hydrate wash after recovering the top wire + fish.
