Narrative
On june 15, 2024 at approximately 15:18 hours consumers energy gas control received notification of a damage at the winterfield storage field, marion township, michigan (osceola county). Gas operations storage employees arrived onsite, confirmed the damage to w-905, and immediately shut-in the well line (wl-905). Despite this, gas continued to release, indicating a loss of control. The well blowout contingency plan was then implemented. An investigation determined a contractor working on behalf of autumn vista dairy using a tractor and tanker to spread fertilizer, had backed into the wellhead, causing a release of gas, and damaging the wellhead and surface components, making the well incapable of isolation. Upon determining the loss of control, personnel began evaluating the site to determine immediate needs and remained onsite until complete isolation of the well was achieved. Consumers energy contacted cudd emergency well response (contractor), informing them of the incident and requesting assistance. Both consumers energy and cudd mobilized at the site on june 16, 2024, to begin planning and implementing the well kill operation. Two attempts to kill the well by suppressing it with liquids were unsuccessful, leading to a decision to use a vendor specialized blow out preventer (bop) to isolate and gain control of the well. On june 19, 2024, the wellbore was successfully isolated using a cudd blowout preventer and an asi-x packer was set and tested. Cudd's bop was removed and replaced with a company bop. Further action includes preparation for the complete well remediation, which will involve integrity diagnostic evaluations through logging and mechanical integrity testing. The well completion will also include installing new tubing, new API 6a surface equipment, and connecting pipeline. On july 24th, 2024, the well was logged with both gamma ray neutron and corrosion logging tools to validate downhole integrity before completing workover activities. This was the second time the well has been logged since its baseline assessment with zero notable changes. A new wellhead was then procured and installed in accordance with consumers energy procedures. The well was then completed with a 2-3/8-inch tubing string and new wellhead components and valves. The remaining work includes final pipeline connection to be completed by local operational and welding crews per their resource and project work plan. The final state of the well, once returned to service will include new API 6a wellhead and valves, replaced pipeline connection, updated downhole integrity logs, wellhead protection and signage. The final pipeline connection was completed by local operational and welding crews, and normal operations resumed on april 24, 2025. Proper protection was also installed to safeguard the pipeline facilities from impact and excavation damage.
