Williams Partners’ Opal, Wyo. Additional Plants Returned to Service, Capacity Meets Customer Needs

Williams Partners’ (NYSE:WPZ) Opal Gas-Processing Plant has returned to service processing capacity of approximately 1.1 billion cubic feet of natural gas per day, following a full shutdown April 23 due to a fire. Four cryogenic processing trains are now operating and a fifth unit, where the fire occurred, remains out of service.

The total capacity of the four operating trains is sufficient to meet customer needs. The two units most recently placed back in service, TXP-4 and TXP-5, have a combined design processing capacity of 700 million cubic feet of gas per day. TXP-4 was idle at the time of the incident, serving as excess capacity for the facility. TXP-1 and TXP-2 were placed back in service last week and have a combined design processing capacity of 395 million cubic feet of gas per day.

The company, in coordination with regulatory agencies, continues to investigate the cause of the incident. Damage was limited to a small area of TXP-3.

Williams Partners Brings Two Units Back into Service at its Opal, Wyo. Gas-Processing Plant

Williams Partners (NYSE:WPZ) has brought back into service two cryogenic processing trains that were shut down last week when a fire occurred at TXP-3, one of the five processing trains at the Opal, Wyo. gas-processing facility. The two units now back in service, TXP-1 and TXP-2, have a combined design processing capacity of 395 million cubic feet of gas per day.

The two other units that were part of the shutdown, TXP-4 and TXP-5, remain offline as the company works to take the necessary steps to bring additional portions of the plant into service in a safe, systematic and timely manner.

At the time of the incident, the Opal Gas-Processing Plant was processing daily inlet volumes of approximately 1 billion cubic feet of natural gas. The capacity of the TXP-1, -2, -4 and -5 plants totals 1.1 billion cubic feet of gas per day, which is sufficient to handle all of the natural gas currently available to the facility. TXP-4 was idle at the time of the fire, serving as excess capacity for the facility.

The initial visual assessment of damage indicates that the impact was largely limited to a small area of the TXP-3 plant. Information from the company’s visual inspection of the damage area indicates that there was a release of natural gas that was subsequently ignited. The company, in coordination with regulatory agencies, is focusing the investigation on the cause of the release and source of ignition.

The entire facility was put in immediate full shutdown when the fire occurred at approximately 2 p.m. local time on April 23. There were no reported injuries or damage to property outside the facility. The plant’s emergency procedures performed as designed.

The company has insurance, subject to retentions (deductibles), for property damage and business interruption; it expects the coverage to mitigate the financial effects of the incident.

The company is working to address the needs of customers whose business is affected by the temporary shutdown of operations at the Opal facility.

 TULSA, Okla. – Williams Partners (NYSE:WPZ) is deploying safety measures and performing initial assessment of damage in a small area of one of the five plants on its 160-acre Opal, Wyo., gas-processing facility that was directly affected by a fire last week.

In coordination with regulatory agencies, the company is assessing damage and developing preliminary plans to bring the other four plants back into service in a safe, systematic and timely manner. The capacity of the four undamaged plants totals 1.1 billion cubic feet of gas per day, which is sufficient to handle all of the natural gas currently available to the facility.

The facility has been shut down since the incident occurred at approximately 2 p.m. local time on April 23. There were no reported injuries or damage to property outside the facility. The plant’s emergency procedures performed as designed.

The Opal Gas-Processing Plant has the capacity to process 1.5 billion cubic feet of natural gas daily via five turbo-expander cryogenic gas-processing units. Although the company has not yet made a full assessment of all plant equipment, the initial visual assessment of damage indicates that the impact was largely limited to a small area of the TXP-3 unit. At the time of the incident, it was one of the four units the plant had running to handle recent daily inlet volumes of approximately 1 billion cubic feet of natural gas. The fifth unit was idle, serving as excess capacity for the facility.

Information from the company’s visual inspection of the damage area indicates that there was a release of natural gas that was subsequently ignited. The focus of the investigation will be on the cause of the release and source of ignition.

Company personnel are inspecting the damaged equipment in cooperation with regulatory authorities. The company plans a detailed assessment of damage, followed by development of plans to address the damaged equipment.

The company has insurance, subject to retentions (deductibles), for property damage and business interruption; it expects the coverage to mitigate the financial effects of the incident.

TULSA, Okla. – Williams Partners L.P. (NYSE: WPZ) and Williams (NYSE:WMB) reported an explosion and fire at approximately 2 p.m. Mountain Time at their natural gas processing facility in Lincoln County, Wyo., near the town of Opal. There were no reported injuries or damage to property outside the facility.

The facility was immediately shut down and emergency procedures were activated. All personnel were safely evacuated from the facility. First-responders evacuated an area that includes the town of Opal and closed Highway 30 in proximity to the plant. Williams is making accommodations for the displaced residents.

The company’s top priority right now is ensuring the safety of our employees and surrounding community, as well as cooperating with the local authorities and regulatory agencies.

Natural-gas gathering from surrounding producing areas is temporarily suspended as a result of the incident. The company is evaluating alternatives so that natural gas production can resume as soon as possible.

The Opal facility processes natural gas gathered from wells in the area in preparation for interstate natural gas pipeline transport. It also produces natural gas liquids from the natural gas. The Opal plant has an inlet capacity of 1.5 billion cubic feet of natural gas per day. Recent daily volumes have been approximately 1 billion cubic feet of natural gas.

The incident is known to have affected TXP-3, one of the five cryogenic processing trains that comprise the Opal facility.
