Brazil's 18mn m³/d Rota 3 natural gas pipeline from the offshore Santos basin is expected to begin operations this year, but market participants are concerned that available volumes will fall short of expectations.
State-controlled Petrobras' 355km (221-mile) pipeline is projected to ship gas from lucrative pre-salt areas in the Santos basin to the Comperj petrochemical complex in Itaborai, Rio de Janeiro, home to the Rota 3 processing facility, which is still under construction. But the pre-salt's high levels of gas reinjection — where gas is pumped back into wells to enhance oil recovery or avoid flaring — may diminish volumes actually travelling through it.
Petrobras expects to make 14.6mn m³/d of gas available to the market through Rota 3, according to its environmental license request to regulator Ibama. But some market participants are concerned the actual volumes made available will be much less and not have an impact on prices, especially given the amount of gas used for reinjections.
Brazil reinjected 85.8mn m³/d of gas in November, while making 57mn m³/d available to the market, from all exploration projects in the country, according to oil and gas regulator ANP.
A portion of the 14.6mn m³/d expected via Rota 3 is also already committed to meet some of Petrobras' gas needs — which will also limit market availability. For instance, the pipeline is expected to supply Petrobras' 1,800MW thermal power plant to be built in the Gaslub complex, in Rio de Janeiro, whose licence was recently requested, among other projects.
The thermal plant plans were already expected by market participants but there is no expected date for the beginning of the power plant's construction.
Petrobras officially requested the required environmental licenses for the plant — which will generate power for self-use and send any surplus to Brazil's grid — from Ibama on 11 December.
Rota 3 stands to get supply from 13 floating production storage and offloading (FPSO) vessels that will be connected to approximately 185 wells in 10 different fields: Buzios, Sururu, Mero, Tres Marias, Sepia, Atapu, Uirapuru, Aram, Sagitario, Sepia and Tupi. But only the last six are set to produce natural gas for the market, meaning that gas from Buzios or Mero — two of Brazil's three main oil and gas production fields — will not reach the market, but will rather be used by Petrobras and other field operators.
But Petrobras expects its oil and gas production to peak between 2028 and 2032, and to keep producing hydrocarbons from the pre-salt cluster until 2057, according to an Ibama technical report - the most recent document related to the project. Furthermore, gas production in some fields may remain steady even after oil output begins to decline, the report also said.
Rota 3 began construction in 2010 was supposed to start operations in 2020, but has suffered a series of delays and is now scheduled to come on line in November.
