Crude slate

ExxonMobil says the refinery is supplied by pipeline crude primarily from Texas and Canada, supplemented by waterborne crude from the Persian Gulf, Africa, South America and Mexico. The Enercoast system that feeds the refinery from Webster lists WTI, Gulf of America medium sour and Canadian heavy among its grades.

Base oils

Group I · 9,800 b/d Group II · 18,200 b/d Group III · 8,000 b/d Group II+ · capacity not published Total 36,000 b/d

Operating. ExxonMobil's production-sites page (accessed 2026-10-24) says the Baytown, Texas refinery currently produces Group II+ EHC 45, Group II EHC 120 and EHC 65 using MSDW and MAXSAT catalyst/process technologies. A Group III addition (Baytown Refinery Reconfiguration / Expansion Project) is under construction: FID August 2025, construction kicked off Jan. 20, 2026, startup targeted 2028, about 8,000 b/d Group III (ALTUM 4 and ALTUM 6) for North America. The 2015 Baytown expansion raised Group II+ EHC 45 output and introduced Group II EHC 65 (exxonmobil.com, 2015-04-29).

API group	b/d	As published	Basis	In effect	Source
Group I ★	9,800	9,800 b/d Trade press figure (Lube Report Americas, 2018-03-14): 'Baytown ... capacity to produce 9,800 b/d of API Group I and 18,200 b/d of Group II'. Earlier (2015) articles trace the Group I figure to the AFPM Lubricating Oil and Wax Capacities Report. ExxonMobil still made Group I Americas Core 600 and 2500 at Baytown in Feb. 2021 (force majeure list). No newer public split exists.	estimate	2018	Lubes'n'Greases low
Group II ★	18,200	18,200 b/d Same 2018 Lube Report Americas statement; includes Group II+ EHC 45, which is not split out. ExxonMobil has not published a Baytown Group II figure; the BRRP (2028) is also expected to raise Group II supply by an undisclosed amount.	estimate	2018	Lubes'n'Greases low
Group III ★	8,000	8,000 b/d Future capacity: ExxonMobil's groundbreaking page says 'once complete, Group III production capacity will be around 8,000 bpd' with startup in 2028; the Aug. 26, 2025 announcement page phrases it as the Group III slate 'supported by production capacity of approximately 8,000 b/d' with a further expansion starting up in 2028, and OGJ/F+L describe it as about 8,000 b/d to be added.

Base oil events and projects

2026-01-20 Expansion Group III baytown-group-iii-brrp
Construction kick-off (groundbreaking) of the Baytown Refinery Reconfiguration Project on Jan. 20 (2026), per OGJ (Feb. 10, 2026): existing units adjusted to shift gasoline output toward distillates and lubricant base stocks; about 8,000 b/d Group III once complete; FID August 2025; startup in 2028 'remains on schedule'. ExxonMobil's own groundbreaking page and F+L Daily (Jan. 22, 2026) confirm construction began; capacity_delta is 0 here to avoid double-counting the 8,000 b/d carried on the announcement event. announced 2025-08-26 · public target 2028 · actual 2026-01-20 Oil & Gas Journal high

ExxonMobil announced (Baytown, Aug. 26, 2025) its Group III base stock slate (4 cSt and 6 cSt) for North America produced at the Baytown complex, supported by about 8,000 b/d of capacity, and a final investment decision to further expand Group III capacity with startup anticipated in 2028. The Baytown EDF reported the Refinery Reconfiguration Project would update three units to make more diesel and base stocks, with construction starting end-2025. announced 2025-08-26 · public target 2028 · +8,000 b/d ExxonMobil Basestocks high

ExxonMobil declared force majeure on Baytown EHC 45, EHC 65, Americas Core 600 and Americas Core 2500 after the February 2021 winter storm shut the refinery the week before the Feb. 24 report; refinery restart began Feb. 22 but the base oil unit was not expected to resume for several weeks.

Not established from public sources: ExxonMobil publishes no Baytown capacity by group; the Group I 9,800 b/d and Group II 18,200 b/d rows are a 2018 trade-press statement (earlier articles trace such figures to the AFPM capacities report) and may be stale after the 2015 expansion recalculation and any later debottlenecks; recorded at LOW confidence. Whether the 8,000 b/d Group III is incremental or the total 2028 capacity is stated inconsistently across ExxonMobil's two pages and the trade press (recorded as the 2028 capacity). No TCEQ air permit for the Baytown Refinery Reconfiguration Project was located in free TCEQ notices (searches returned only olefins-plant and Title V items); the project's three affected units are not named in any page opened. Process route: ExxonMobil names only MSDW and MAXSAT catalyst technologies; the Group I route (presumably solvent refining) is not described on any page read, so only hydrocracking_dewaxing is recorded. Feedstock internal_vgo is inferred from the integrated-refinery description (units adjusted to shift gasoline output toward base stocks), not stated. Logistics modes: ExxonMobil mentions 'multiple load points and storage facilities' but no modes. No posted price change by ExxonMobil since 2020 was captured (ExxonMobil does not post prices publicly in the reports read). 1 value is held back because only a paid source supports it.
