US majors unfazed by Permian bottlenecks
The two largest US-based oil and gas producers remain unfazed by pipeline bottlenecks in Texas' Permian basin as they ramp up drilling activity to drive output growth there.
ExxonMobil and Chevron are redoubling their efforts to boost unconventional output even as the Permian basin — a major area of operation for both — faces growing pipeline and other infrastructure constraints to move crude and associated natural gas out of the region. The shortage, which is likely to worsen later this year and last at least until the middle of next year, has already widened the discount in the region's crude prices to more than $10/bl against Nymex WTI.
Chevron's Permian shale output rose to 270,000 b/d of oil equivalent (boe/d) in the second quarter, up by 92,000 boe/d from a year earlier, but it "is not materially exposed to the Midland basis differential", upstream executive vice-president Jay Johnson says. That is because it has agreements in place to lift all forecast output, both from projects it operates and those it is a partner in, from the region this year and in 2019. "Agreements are in place to access additional pipeline capacity in early 2019 in line with our production growth forecast," Johnson says.
Pipeline takeaway capacity and output do not always align. Chevron in June had surplus pipeline takeaway capacity of 50,000 b/d from the Midland basin, which is part of the Permian. It filled that space by buying volumes from third-party producers. To ensure it has capacity across the supply chain, the major has agreements in place to further increase its dock capacity in the Houston Ship Channel in 2019, so that its Permian output can tap the export market. Chevron has exported 8mn bl of liquids from the US Gulf coast so far in 2018, allowing it "to secure the highest value", Johnson says.
In addition to infrastructure, operators in the basin have to contend with a shortage of truck drivers, drill site workers, equipment and inputs such as sand and water, all of which increase costs. Chevron, which has 19 rigs in the region, up from 17 in the first quarter, says it has not experienced any shortages and is close to meeting its growth plans.
The sheer size of its operations helps. So far this year, it has swapped, farmed out or sold 31,000 acres (125km²) in the Permian to pare its acreage and drill longer lateral wells. Overall, the average length of each well has increased by 35pc since 2016, and it continues to look for more such deals. "We do not intend to slow down activity or divert capital," Johnson says.
Moving on
ExxonMobil's Permian activity is running ahead of schedule. It has 34 rigs in the basin, 17 each in the Midland and Delaware, and six in the Bakken in North Dakota. This compares with 27 in the Permian and four in the Bakken in the first quarter, and a 2018 target of 36 in total with 30 in the Permian. Amid the ramp-up, shale output from the Permian and the Bakken increased by 30pc from a year earlier to 250,000 boe/d during the quarter.
To ensure takeaway capacity keeps pace with output, ExxonMobil is undertaking a huge pipeline and processing expansion to move oil from the Permian to the Houston area and Beaumont, home to its two big Texas refineries. In addition to a terminal in Wink, Texas, that it acquired last year, ExxonMobil announced a joint venture with Plains All American Pipeline in June, through which it plans to move 1mn b/d of crude and condensate from the basin. The line will start at Wink and links to its 560,500 b/d Baytown refinery and 362,000 b/d Beaumont plant.
And the firm has secured capacity to move liquids from the Permian through 2022 and associated gas through 2020. "We have no concerns about evacuation capacity both in gas and liquids for our Permian business," ExxonMobil senior vice-president Neil Chapman says.

Tankers can take TMX crude mid-May: Trans Mountain
Tankers can take TMX crude mid-May: Trans Mountain
Calgary, 1 May (Argus) — Commercial operations for the 590,000 b/d Trans Mountain Expansion (TMX) crude pipeline in western Canada have officially started today, but tankers will not be able to load crude from the line until later this month. Line fill activities, which began on 16 April, are still ongoing for the C$34bn ($25bn) project that stretches from Edmonton, Alberta, to the docks in Burnaby, British Columbia. About 70pc of the volumes needed are in the 1,181 kilometre (733 mile) line, Trans Mountain said on Wednesday. "As of today, all deliveries for shippers will be subject to the Expanded System tariff and tolls, and tankers will be able to receive oil from Line 2 by mid-May," Trans Mountain said. Aframax-size crude tankers started to take position on the west coast last month in anticipation of the new line. But the inability to deliver crude at Burnaby, while still having to pay full tolls, was a concern raised by several shippers on 23 April. "Trans Mountain must be able to receive, transport and deliver a shipper's contract volume," the shippers said in a letter to the CER. The ability to deliver the crude is "clearly central and fundamental qualities of firm service." The CER in November approved interim tolls for the system that will further connect Albertan oil sands producers to Pacific Rim markets. Shippers will, at least initially, pay C$11.46/bl to move crude from Edmonton, Alberta, to the Westridge terminal in Burnaby, British Columbia. The fixed portion accounts for C$10.88/bl of this and has nearly doubled from a C$5.76/bl estimate in 2017. The Canada Energy Regulator (CER) on 30 April gave Trans Mountain a green light to put TMX into service , ending years of uncertainty that the project would ever be completed. The expansion project, or Line 2, nearly triples the capacity of Canadian crude that can flow to the Pacific coast, complementing the original 300,000 b/d line, or Line 1, that has been operating since 1953.

Canada’s TMX pipeline ready to move crude: Update
Canada’s TMX pipeline ready to move crude: Update
Adds regulatory approvals received. Calgary, 30 April (Argus) — Canada's 590,000 b/d Trans Mountain Expansion (TMX) crude pipeline can now start moving volumes to the Pacific coast after receiving final regulatory approvals today, more than a decade after the project was first conceived. The Canada Energy Regulator (CER) approved Trans Mountain's final applications on Tuesday, giving the midstream company a green light to put its C$34bn ($25bn) project into service. Trans Mountain had recently maintained its commitment to being ready by 1 May. The expansion nearly triples the existing 300,000 b/d Trans Mountain line that runs from Edmonton, Alberta, to Burnaby, British Columbia. Also expanded was the Westridge Marine Terminal from one dock to three, all capable of loading Aframax-sized vessels. The line will provide Canadian oil sands producers with a significant export outlet without having to first go through the US. Much of the new volume to flow on TMX is expected to be heavy sour crude. Federally-owned Trans Mountain had submitted applications as recent as 15 April for the final section of the pipeline about 140 kilometers (87 miles) east of the line's terminus in Burnaby. The final applications concerned piping, valves and other components at two pipeline inspection device traps and the mainline pipe between the two traps. The traps were added for safety assurance when the operator was allowed by CER to use a smaller diameter pipe as part of the Mountain 3 deviation. Mountain 3 was the last segment of the pipeline to be constructed because of delays relating to difficult terrain while tunneling. The "golden weld" marking the end of construction occurred on 11 April, according to Trans Mountain. A group of shippers last week expressed concern that TMX would not be ready for commercial service by 1 May. The pipeline had been marred by legal challenges and cost over-runs since it was first proposed in 2013 by its then-owner US midstream firm Kinder Morgan. The Canadian government took ownership of it in 2018. By Brett Holmes Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group . All rights reserved.
New US rule may let some shippers swap railroads
New US rule may let some shippers swap railroads
Washington, 30 April (Argus) — US rail regulators today issued a final rule designed to help customers switch railroads in cases of poor rail service, but it is already drawing mixed reviews. Reciprocal switching, which allows freight shippers or receivers captive to a single railroad to access to an alternate carrier, has been allowed under US Surface Transportation Board (STB) rules. But shippers had not used existing STB rules to petition for reciprocal switching in 35 years, prompting regulators to revise rules to encourage shippers to pursue switching while helping resolve service problems. "The rule adopted today has broken new ground in the effort to provide competitive options in an extraordinarily consolidated rail industry," said outgoing STB chairman Martin Oberman. The five-person board unanimously approved a rule that would allow the board to order a reciprocal switching agreement if a facility's rail service falls below specified levels. Orders would be for 3-5 years. "Given the repeated episodes of severe service deterioration in recent years, and the continuing impediments to robust and consistent rail service despite the recent improvements accomplished by Class I carriers, the board has chosen to focus on making reciprocal switching available to shippers who have suffered service problems over an extended period of time," Oberman said today. STB commissioner Robert Primus voted to approve the rule, but also said it did not go far enough. The rule adopted today is "unlikely to accomplish what the board set out to do" since it does not cover freight moving under contract, he said. "I am voting for the final rule because something is better than nothing," Primus said. But he said the rule also does nothing to address competition in the rail industry. The Association of American Railroads (AAR) is reviewing the 154-page final rule, but carriers have been historically opposed to reciprocal switching proposals. "Railroads have been clear about the risks of expanded switching and the resulting slippery slope toward unjustified market intervention," AAR said. But the trade group was pleased that STB rejected "previous proposals that amounted to open access," which is a broad term for proposals that call for railroads to allow other carriers to operate over their tracks. The American Short Line and Regional Railroad Association declined to comment but has indicated it does not expect the rule to have an appreciable impact on shortline traffic, service or operations. Today's rule has drawn mixed reactions from some shipper groups. The National Industrial Transportation League (NITL), which filed its own reciprocal switching proposal in 2011, said it was encouraged by the collection of service metrics required under the rule. But "it is disheartened by its narrow scope as it does not appear to apply to the vast majority of freight rail traffic that moves under contracts or is subject to commodity exemptions," said NITL executive director Nancy O'Liddy, noting it was a departure from the group's original petition which sought switching as a way to facilitate railroad economic competitiveness. The Chlorine Institute said, in its initial analysis, that it does not "see significant benefit for our shipper members since it excludes contract traffic which covers the vast majority of chlorine and other relevant chemical shipments."

First TMX cargo booked on Aframax to China
First TMX cargo booked on Aframax to China
Houston, 30 April (Argus) — The first cargo shipped on the Trans Mountain Expansion (TMX) crude pipeline is scheduled to load on an Aframax in Vancouver, British Columbia, beginning 18 May for June delivery in China, according to sources with knowledge of the transaction. Suncor provisionally booked the Aframax Dubai Angel for a Vancouver-China voyage at $3.5mn lumpsum, equivalent to $6.39/bl for Access Western Blend, market participants said. In March, China's state-run Sinochem purchased the first TMX cargo — 550,000 bl of Canadian Access Western Blend — for June delivery. The shipping fixture would mark the first Vancouver-China crude delivery since May 2023, according to Vortexa, a possible indicator of steady Asia-Pacific demand to come with increased maritime access for Canadian oil producers. China already receives heavy sour Canadian crude re-exported from the US Gulf coast, with about 110,000 b/d arriving in 2023, Vortexa data show. The new 590,000 b/d pipeline begins commercial service on 1 May, with three Aframax-capable berths at Vancouver's Westridge Marine Terminal, up from one previously. An oversupply of Aframax crude tankers on the west coast of the Americas in anticipation of TMX-driven demand pressured Vancouver-loading rates to six-month lows on 19 April , according to Argus data, but market participants expect demand to increase beginning in the second half of May. Three regulatory approvals remained under assessment by the Canada Energy Regulator (CER) on 30 April. The applications concern piping, valves and other components at two pipeline inspection device traps and the mainline pipe between the two traps. The traps were added for safety assurance when the operator was allowed by CER to use a smaller diameter pipe as part of the Mountain 3 deviation.
