MOSCOW (MRC) -- A small earthquake hit operations at two oil refineries in Martinez, California, reported Reuters with referenece to the companies' statement.
Marathon Petroleum Corp said it was working to return its 161,500-barrel-per-day refinery to normal operations following a quake centered in nearby Pleasant Hill, with a magnitude of 4.5.
The company confirmed an upset, or malfunction, resulting from the quake but said it did not result in any “known spills or releases” or injuries.
"Marathon Petroleum personnel are working to assess the integrity of equipment to ensure a safe restart and return to normal operations," the company said in a statement.
Marathon had earlier reported the shutdown of multiple units because of the earthquake in a filing with the state pollution regulator. "No off-site consequences are anticipated," the filing said.
Energy intelligence service Genscape earlier reported that a 37,000-bpd hydrocracker, 26,000-bpd catalytic reformer, 40,000-bpd hydrotreater, 14,000-bpd alkylation unit and a hydrogen plant were shut at the plant because of the incident.
Nearby, Royal Dutch Shell Plc said some equipment had been temporarily affected at its 156,400-barrel-per-day (bpd) refinery in Martinez, but that operations were now normal.
There were no major damages or injuries due to the quake in the Bay Area, local media reported.
A magnitude 4.5 quake is relatively small for earthquake-prone California, which lies on the San Andreas Fault.
As MRC informed earlier, Royal Dutch Shell Plc has restarted the hydrocracker at its 225,300 barrel-per-day (bpd) Norco, Louisiana, refinery. The 40,000 bpd hydrocracker was shut on Sept. 9 for a planned month-long overhaul. A longer than expected restart of the unit stretched the outage to six weeks. Shell also conducted maintenance works at its cracker in Norco with the capacity of 840,000 tonnes of ethylene per year over the stated period.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and polyprolypele (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,436,390 tonnes in the first eight months of 2019, up by 9% year on year. Shipments of all PE grades increased. At the same time, the PP consumption in the Russian market was 909,260 tonnes in January-August 2019, up by 10% year on year. Shipments of PP block copolymer and homopolymer PP increased.
Royal Dutch Shell plc is incorporated in England and Wales, has its headquarters in The Hague and is listed on the London, Amsterdam, and New York stock exchanges. Shell companies have operations in more than 70 countries and territories with businesses including oil and gas exploration and production; production and marketing of liquefied natural gas and gas to liquids; manufacturing, marketing and shipping of oil products and chemicals and renewable energy projects.
