Talos Energy Achieves Successful Results from Lime Rock and Venice Prospects

Houston, Texas, January 3, 2023 – Talos Energy Inc. (“Talos” or the “Company”) (NYSE: TALO) today announced that the Company’s Lime Rock and Venice prospects both successfully discovered commercial quantities of oil and natural gas during sequential drilling operations in the fourth quarter of 2022. Talos holds a 60% working interest in the two deepwater discoveries, both of which are located near the Company’s 100% owned and operated Ram Powell platform, where future production from both wells will flow via subsea tiebacks.

Lime Rock and Venice Highlights:

• 78 feet and 72 feet of net hydrocarbon pay in the primary targets at Lime Rock and Venice, respectively, with excellent geologic qualities; Talos collected pressure, fluid and core samples from the wells to confirm the discoveries.

• Expected combined gross production rates in-line with pre-drill estimates of approximately 15-20 thousand barrels of oil equivalent per day (“MBoe/d”); the two wells will produce through a shared riser system at the Ram Powell facility.

• Expected combined gross recoverable resources in-line with pre-drill estimates of 20-30 million barrels of oil equivalent (“MMBoe”), averaging approximately 40% oil and 60% liquids.

• Expected completion operations in the second half of 2023, with first production from both wells by the first quarter of 2024.

• Subsea tieback distance to the Ram Powell facility of 9 miles for the Lime Rock discovery and 4 miles for the Venice discovery.

• Talos will collect volume-based production handling fees (“PHA fees”) from non-operated partners in both discoveries.

Talos President and Chief Executive Officer Timothy S. Duncan commented: “I’m proud of our team for starting our deepwater drilling campaign with consecutive early successes. These two discoveries are case studies of the exciting potential that infrastructure-led development can bring in the U.S. Gulf of Mexico. For Talos, that translates to providing material production and cash flow in 2024 and beyond while reducing our operating cost structure through PHA fees and our carbon intensity through low emission subsea production. Demonstrating our ability to successfully leverage existing infrastructure also reinforces the strategic merits of our pending acquisition of EnVen Energy Corporation, which will double our deepwater infrastructure footprint by adding six major facilities. Ram Powell provides a blueprint for future optimization, development and exploration potential around those assets and our own.”

The Lime Rock and Venice discoveries are representative of the Company’s strategy of utilizing infrastructure acquired through active business development as a cornerstone for the Company’s organic growth strategy. Following its installation as the deepest production facility in the world at the time, Ram Powell produced approximately 250 MMBoe until Talos acquired the asset in 2018. The Company then initiated numerous optimization projects that increased production rates, reduced costs and initiated a third-party production handling agreement. Simultaneously, Talos applied proprietary seismic reprocessing techniques to multiple recent vintage seismic surveys to identify new drilling prospects near Ram Powell, including Lime Rock and Venice.

The Lime Rock prospect was acquired in Lease Sale 256 in November of 2020 and is located approximately 9 miles from the Ram Powell facility. The Venice prospect was identified within the existing Ram Powell unit acreage approximately 4 miles from the Ram Powell facility. Talos originally held a 100% working interest in both prospects prior to successful farm-downs to achieve its targeted 60% working interest. The Company expects the Lime Rock and Venice discoveries to bring Ram Powell’s production rates to levels last seen approximately 15 years ago.

Lime Rock and Venice are the first two deepwater exploitation wells in the Company’s current open-water rig program that started in the fourth quarter of 2022 and which will continue in the first half of 2023 with the Rigolets and Lisbon prospects, among others. Separately, Talos expects results from its operated Mount Hunter development well and its non-operated Puma West exploration well in the first quarter of 2023. The Company’s non-operated Pancheron exploration well is also expected to spud in the first half of 2023.

Estimates for our future production volumes are based on assumptions of capital expenditure levels and the assumption that market demand and prices for oil and gas will continue at levels that allow for economic production of these products. The production, transportation, marketing and storage of oil and gas are subject to disruption due to transportation, processing and storage availability, mechanical failure, human error, hurricanes and numerous other factors. Our estimates are based on certain other assumptions, such as well performance, which may vary significantly from those assumed. Therefore, we can give no assurance that our future production volumes will be as estimated.

RESERVE INFORMATION

Estimates of recoverable hydrocarbon volumes and related measures as presented herein are based on internal data prepared by the Company’s management team in reliance on several assumptions. Reserve engineering is a process of estimating underground accumulations of oil, natural gas and NGLs that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions upward or downward of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGLs that are ultimately recovered.

In addition, we use the terms “expected combined gross recoverable resource” and “net hydrocarbon pay” in this release, neither of which is a measure of “reserves” prepared in accordance with SEC guidelines or permitted to be included in SEC filings. These resource estimates are inherently more uncertain than estimates of reserves prepared in accordance with SEC guidelines.
