… Still a compressor to install

ExxonMobil has announced that oil production, which had fallen to around 30,000 barrels of oil a day (bpd) following the reappearance of compressor problems aboard the Liza Destiny, increased to between 100,000 and 110,000 barrels per day.

The Liza Destiny FPSO

According to a statement from the company’s Public Affairs and Governance Adviser Janelle Persaud, teams on Liza Destiny’s Float Production Storage and Unloader (FPSO) have removed the discharge silencer from the compressor for further assessment of the damage.
“We estimate that repairs or replacements will take about three months. In addition, plans initiated in 2020 are progressing to install a redesigned third-stage flash gas compression system at the end of this year, ”said Persaud.
With regard to torch, which had been reduced to between 4 and 5 million cubic feet of gas a day after recent problems with the compressor, Persaud explained that current increased production figures would be in line with a flare not more than 15 million cubic feet of gas per day.
“These operating parameters were defined after careful consideration of safety, environmental, technical and economic factors, together with discussions with relevant Government agencies on the best way forward while repairs and upgrades continue,” he said in the statement.
“ExxonMobil Guyana is extremely disappointed by these ongoing technical challenges, but we are proud of the offshore team who continue to work safely and efficiently manage operations during the COVID-19 pandemic. We will continue to work with the relevant parties to put things right as soon as possible. ”
Opposition Leader Joseph Harmon, who had expressed concerns about the troubled gas compressor on FPSO’s Liza Destiny ship, had previously requested a meeting with local ExxonMobil executives, a US oil giant, to be briefed on the matter.
According to Persaud, a meeting is being organized, and could even happen as early as today.

Additional problem
Last week, Exxon had revealed, as it was conducting the final testing phase of the replacement flash gas compressor and other system components on the> FPSO, I encountered an additional problem with the release silence.
The US oil giant reported that a team of SBM Offshore, German manufacturer MAN Energy Solutions and ExxonMobil was on site to assess repairs with the support of engineering experts in Europe and the USA.
“We have reduced production to a minimum level that mitigates hydrate formation in subsea systems, maintains gas injection and gas into the power generators, and reduces flare,” said the company.
When asked, Persaud had revealed that this meant the company was producing some 30,000 bpd – a reduction of an initial 120,000 bpd. This fall, he noted the potential to throw Exxon’s next lift, which was scheduled for the next few days.
When asked about the amount of torching in light of production cuts, Persaud had revealed that torching is now at 4 to 5 million cubic feet of gas per day, just above pilot levels.
Excessive torching had averaged 16 million cubic feet of gas per day following the compressor malfunction in February.
Subsequently, the Government of Guyana had expressed disappointment at the failure to resolve the issues with the gas compressor on its oil platform, which not only led to increased torching, but now a sharp fall in production as well. As such, it has suggested possible actions against the oil company.
In a statement, the Ministry of Natural Resources said “The GoG is, as would be expected, very disappointed with the Operator’s inability to resolve this situation to date, and will continue to monitor daily crude oil output levels and flares in order to allow best for an economically viable level of production during this period. The GoG is currently examining the implications of losing output, and consequently losing income and revenue, including measures they may have to put in place to protect national interest. “
However, the Ministry noted that GoG’s crude oil lift, which was safely and successfully completed the day before, has not affected the planned volume and in accordance with the Raw Delivery Agreement and Lifting Schedule. That was the Government’s second lift for 2021.
In addition, Exxon’s reduced production was announced the same day as Natural Resources Minister Vickram Bharrat was projected to project Guyana producing 1 million barrels of raw per day and leading the Western Hemisphere in oil production.
“By 2027, we hope to have at least seven floating production, storage and unloading (FPSO) vessels in the country, and that we will produce either close or even over one million b / d,” he said. r Minister Bharrat. (G3)
