Production capacity · barrels per stream day
Crude slate
Built around heavy and medium sour crude (the 2012 expansion added a 325,000 b/d crude unit and a second coker for it), with lighter domestic barrels blended in. Aramco Trading Americas has supplied all of it since 2023. Sources seen: Canadian heavy on Keystone via the Port Neches Link; domestic and waterborne crude through the Nederland terminal; imports over the Port Neches docks. In February 2026 Aramco's trading arm bought a cargo of Venezuelan Boscan heavy from Chevron for March delivery, Motiva's first Venezuelan purchase since 2019. A breakdown by country was not found; EIA company-level import data would give it.
Base oils
Motiva's own pages describe the Port Arthur base oil plant as operating and 'the largest base oil plant in the Western Hemisphere' with three lube hydroprocessing units (motiva.com base oils page, accessed 2026-10-24). Products are now sold under the Aramco brand family (aramcoPRIMA Group II, aramcoULTRA Group III); the earlier 'Star' / 'Star HVI' brand names no longer appear on Motiva's site. Motiva posted new prices effective 2026-10-01 (Argus), consistent with continued operation. No Group III expansion project at Port Arthur was found in public sources. Classification: Motiva's base oils page heads its product list 'Group II and III Base Oils Produced By Motiva' (aramcoPRIMA Group II, aramcoULTRA Group III) and says Motiva produces 'premium Group II and Group III base oils'; Group I appears on that page only for Aramco affiliates (S-OIL), not Motiva (accessed 2026-10-25). Classed as Group II and Group III; the 40,000 b/d total is still unsplit.

Outage
Group II
Motiva reduced rates or shut the 40,300 b/d Port Arthur Group II/III base oil plant ahead of Hurricane Laura; as of Thursday Sept. 3, 2020 the plant had not restarted, attributed to a general power outage, with a restart expected over the following weekend. No force majeure was reported for Motiva. actual 2020-09-03 Lubes'n'Greases medium
Not established from public sources: No public source splits Port Arthur capacity by API group; the operator gives only a 40,000 b/d total (trade press: 40,300 b/d, 'mostly Group II'), so the capacity rows use api_group 'unknown'. Motiva has said it will not disclose a Group III volume and switches among its three lube trains to make Group III as needed (Lube Report, 2017-12-06). Argus's 2026 price report shows Motiva posting Group II+ and Group III 8 cSt grades; whether those are Port Arthur-made or S-Oil-sourced aramcoULTRA could not be established, so they are not listed as plant grades. The 2017 Lube Report describes two vacuum units, three solvent extraction units and three catalytic dewaxing units, while Motiva's page says hydrotreated, isodewaxed and hydrofinished; process_route records both hydrocracking_dewaxing and hydroisomerization. Logistics modes are not stated on any page opened. Ownership (Aramco 100% via Saudi Refining, Inc.) rests on Aramco's 2017 separation release (https://aramco.com/en/news-media/news/2017/motiva-shell-aramco-separation, read 2026-10-24), which also cites a 40,000 b/d base oil plant. No Group III expansion project at Port Arthur and no 2022-2025 outage or turnaround could be found in free pages. Viscosities for aramcoULTRA 4/6 are taken from the 2017 launch description (4 cSt and 6 cSt cuts), not from a current data sheet; the product data files on motiva.com were not opened. 1 value is held back because only a paid source supports it.

|---|---|---|---|---|---|
| crude in | pipeline | Keystone Pipeline (via Port Neches Link) The Port Neches Link Pipeline (in service March 2023, 4 mi/36in) was purpose-built for last-mile connectivity from Keystone/Marketlink's Nederland Delivery Station to Motiva's Port Neches terminal feeding the Port Arthur refinery. |
South Bow Keystone Nederland Delivery Station | crude | source |
| crude in | pipeline | ETP Crude PANS Pipeline (Nederland Terminal to the refinery) ETP Crude LLC's Texas tariff TX No. 14.5.0 (effective July 1, 2026) publishes a trunk rate of 20.57 cents a barrel on crude from the ETNT Nederland Terminal to the Motiva Refinery, Jefferson County; the same tariff delivers to the Total refinery and to Zydeco at Port Neches. Sunoco built the 12-mile, 30-inch line for the refinery's expansion. Nederland is where Seaway's ECHO-to-Beaumont/Port Arthur lateral, Energy Transfer's Permian lines and waterborne crude come together, so barrels from those systems reach the refinery through this line. |

| crude in | marine | Sabine-Neches Waterway Port Neches Terminal is primarily a crude dock: No. 1 Dock (800 ft, 40 ft depth) receives and ships crude and products; No. 2 (950 ft, 40 ft) receives crude, naphtha, products and gas oil; No. 3 (600 ft, 28 ft) crude, naphtha, gas oil (NOAA Coast Pilot 5). Motiva says its Port Arthur and Port Neches terminals dock more than 1,000 vessels a year. |

| crude in | pipeline | Seaway / Enterprise ECHO (indirect, through Nederland) RBN describes ECHO as connected to refiners in Beaumont / Port Arthur. No tariff or operator document was found naming a direct Seaway or ECHO delivery into the Motiva refinery; the lateral ends at terminals in the Beaumont / Nederland area, from where crude moves on the Nederland line above. Kept as context, not as a connection of its own. |

| products out | pipeline | Colonial Pipeline Refinery ties into Colonial, Explorer and Magtex; more than 95% of its gasoline and middle distillates move to market by pipeline. Colonial's local Port Arthur tariff (FERC 3.33.0) prices the pump-over from the Port Arthur Products Station to Colonial; Colonial's mainline rates run from Hebert, which its tariffs define as Beaumont and Port Arthur. |

| products out | pipeline | Explorer Pipeline Refinery ties into Colonial, Explorer and Magtex (A Barrel Full). Explorer's local Port Arthur station rates are on Colonial FERC 3.33.0 (Port Arthur Products Station to Explorer). Enterprise's 2009 Port Arthur storage project built distribution connections from Motiva to Colonial, Explorer and Magtex. Oil & Gas Journal (June 2010) lists Explorer among the systems the Enterprise storage site connects the refinery to. Explorer's tariff names the origin only as Port Arthur, so the link rests on these sources rather than on the tariff. |

| products out | pipeline | TEPPCO / Enterprise TE Products Pipeline Enterprise's 2009 Port Arthur refined products storage (20 tanks, five 3.5-mile product lines to the Motiva refinery) gave Motiva access to Enterprise's TE Products system as well as Colonial, Explorer and Magtex. |

This is the line trade sources call Magtex; it is Sunoco's (Energy Transfer's), not Magellan's. Oil & Gas Journal (June 2010) lists Sunoco with Colonial, Explorer and TE Products as the systems the Enterprise storage site connects the refinery to. |

| products out | marine | Sabine-Neches Waterway / Gulf ICW NOAA Coast Pilot 5 (Jul 2026) lists both Port Arthur Terminal docks for shipment of petroleum products (No. 1 also receives MTBE). Motiva's Port Arthur terminal is its finished-products dock; the Port Neches terminal is primarily crude. Its terminals dock more than 1,000 vessels a year, ships and barges. The Sabine-Neches Waterway meets the Gulf Intracoastal Waterway at Port Arthur, so barges reach GIWW terminals from Brownsville to Mobile. Coastwise tanker destinations are not published. |
Motiva Port Arthur Terminal: No. 1 Dock (Berths 6-7, 1,500 ft, 37 ft depth, 29.8331 N 93.9569 W) and No. 2 Dock (Berths 1-2, 700 and 1,100 ft, 37 ft, 29.8286 N 93.9600 W) | gasoline distillate jet fuel | source |

Rates are pipeline line-haul transcribed from published FERC tariffs; every figure cites its tariff and item. Cost to serve (netback) adds origin spot price and destination fees. "Confirmed" links match a tariff delivery point to the facility; "same city" means the point is in the facility's city — plausible, not proof; "per research" means the facility's research profile names the pipeline as an outlet.
