Gregory P. Hill
President and Chief Operating Officer at Hess
Thanks, John. 2022 was another year of strong strategic execution and operational performance for Hess. Proved reserves at the end of 2022 stood at approximately 1.26 billion barrels of oil equivalent. Net proved reserve additions of 184 million barrels of oil equivalent were primarily the result of the Yellowtail sanction in Guyana and the Bakken. Excluding asset sales, we replaced 144% of 2022 production at a finding and development cost of approximately $14.80 per barrel of oil equivalent.
Turning to production. In the fourth quarter of 2022, Company-wide net production averaged 376,000 barrels of oil equivalent per day, excluding Libya, which was above our guidance of approximately 370,000 barrels of oil equivalent per day. Strong performance across the portfolio more than offset the severe winter weather impacts experienced in the Bakken during the month of December. For the full year 2023, we forecast net production to average between 355,000 and 365,000 barrels of oil equivalent per day, an increase of approximately 10% compared with 2022 production of 327,000 barrels of oil equivalent per day, excluding Libya.
For the first quarter of 2023, we forecast Company-wide net production to average between 345,000 and 355,000 barrels of oil equivalent per day. In the Bakken, fourth quarter net production of 158,000 barrels of oil equivalent per day was below our guidance of 165,000 to 170,000 barrels of oil equivalent per day, reflecting severe winter weather impacts in December, which limited our new wells online to only 15 in the quarter.
For the full year 2022, net production averaged 154,000 barrels of oil equivalent per day. In 2023, we plan to operate four rigs and expect to drill approximately 110 gross operated wells and bring online approximately 110 new wells. In the first quarter of 2023, we plan to drill approximately 25 wells and bring 25 new wells online.
In 2022, our drilling and completion cost per Bakken well averaged $6.4 million. In 2023, we estimate industry inflation will average between 10% and 15%. However, we expect to mitigate this impact through the application of lean manufacturing and technology and forecast our D&C cost to average approximately $6.9 million per well or about 8% above last year.
For the full year 2023, we forecast Bakken net production will average between 165,000 and 170,000 barrels of oil equivalent per day. First quarter net production is forecast to average between 155,000 and 160,000 barrels of oil equivalent per day, reflecting weather contingencies and the carryover effects from the severe winter weather in December. Net Bakken production is forecast to steadily grow over the course of '23 and '24 and average approximately 200,000 barrels of oil equivalent per day in 2025. We expect to hold this level of production for nearly a decade.
Moving to the offshore, in the Deepwater Gulf of Mexico, net production averaged 35,000 barrels of oil equivalent per day in the fourth quarter and 31,000 barrels of oil equivalent per day for the full year 2022. For the first quarter and full year 2023, we forecast net production in the Gulf of Mexico will average approximately 30,000 barrels of oil equivalent per day, reflecting normal field declines and planned maintenance. The Deepwater Gulf of Mexico remains an important cash engine for the Company, as well as a platform for growth.
In 2023, we plan to participate in four wells, one infrastructure-led exploration well, one hub class exploration well, and two tieback wells. The infrastructure-led exploration well will be the Hess-operated Pickral Prospect located in Mississippi Canyon Block 727, which is expected to spud in April and will be brought online through existing infrastructure at Tubular Bells. The well will target the same Miocene interval that was successfully drilled at Esox and tied back to Tubular Bells in 2020.
The hub class exploration well will be spud in the second half of the year and will be a Hess-operated opportunity in the Northern Green Canyon area in the Gulf of Mexico, targeting high-quality sub-salt Miocene sands in areas where the application of the latest seismic imaging technology has improved the sub-salt image. The two tieback wells will be spud in the fourth quarter, one well will be at Stampede and the second well will be at the Shell-operated Llano field. First oil from both wells is expected in 2024.
In Southeast Asia, net production from the joint development area in North Malay Basin, where Hess has a 50% interest, averaged 67,000 barrels of oil equivalent per day in the fourth quarter and 64,000 barrels of oil equivalent per day for the full year 2022. For the first quarter and full year 2023, we forecast net production in Southeast Asia, the average between 60,000 and 65,000 barrels of oil equivalent per day.
Turning to Guyana, where Hess has a 30% interest in the Stabroek Block and ExxonMobil is the operator, the partnership delivered exceptional facilities for liability, project delivery and exploration success in 2022. Net production from Guyana averaged 116,000 barrels of oil per day in the fourth quarter of 2022 and 78,000 barrels of oil per day for the full year 2022, both above our guidance. For the first quarter and the full year 2023, we forecast net production in Guyana to average approximately 100,000 barrels of oil per day.
Turning to developments. Liza Phase 1 was successfully debottlenecked in 2022 and has been operating at or above its revised nameplate capacity of 140,000 barrels of oil per day. Liza Phase 2, utilizing Liza Unity FPSO, achieved first oil in February of last year and production ramp-up from start-up to nameplate capacity was achieved in about five months, which is world-class performance in the deepwater.
The Liza Unity is currently operating at or above its nameplate capacity of 220,000 barrels of oil per day. Production optimization opportunities are currently being considered for late 2023. The third development, Payara, is approximately 93% complete. The Prosperity FPSO is expected to depart from Singapore in late first quarter and commence hookup and commissioning activities following arrival in Guyana. The project remains ahead of schedule and is anticipated to achieve first oil by the end of 2023.
In Yellowtail, our fourth development, is approximately 40% complete and remains on track for first oil in 2025. The One Guyana FPSO was -- hull is completed and is expected to enter drydock in Singapore in April. Topside fabrication activities have commenced and module fabrication sites in Singapore and China and development drilling is underway. The final development plan for our fifth development, Uaru, was submitted in November, and we are currently awaiting approval by the Government of Guyana, which we anticipate by the end of the first quarter. Pending government approvals, our sixth development, Whiptail, is expected to be sanctioned early next year.
Turning to exploration. The Fangtooth Southeast-1 well, located approximately 8 miles southeast of the original Fangtooth-1 discovery well, resulted in a significant new oil discovery, and this area could form the basis for a future oil development on the Stabroek Block. The Fangtooth Southeast-1 well encountered approximately 200 feet of oil bearing sandstone reservoirs and further appraisal activities are underway. We continue to see multi-billion barrels of additional exploration potential on the Stabroek Block. And in 2023, we plan to drill approximately 10 exploration and appraisal wells that will target a variety of prospects and play types. These will include lower risk wells near existing discoveries and several penetrations that will test deeper intervals.
With regard to upcoming wells, operations are continuing at the Tarpon Fish-1 well in the northwest corner of the Stabroek Block, approximately 43 miles northwest of the Liza-1 well. The well is in the first test of cretaceous age clastic reservoirs in Northwest Stabroek. The well will also test a deeper Jurassic aged carbonate prospect.
Lancetfish-1 is a deep play exploration well, located approximately 2.5 miles northeast of the Fangtooth Southeast-1 well that underlies a portion of the Liza field. Drilling operations are underway on the Noble Don Taylor drillship. Beyond that, there is a well called Basher [Phonetic], which will target a deep prospect in the Fangtooth area and a well called Blackfin, which will penetrate an updip upper campaigning prospect east of Barreleye.
Moving to offshore Canada, we plan to participate in the BP-operated FSS-1 well in the Northern Orphan Basin. The well will target a very large submarine fan of tertiary age. The Stena IceMAX rig is expected to arrive on location in the second quarter to spud well, which is located in approximately 4,000 feet of water. BP has a 50% working interest and Hess and Chevron, each have 25%.
In summary, our execution in 2022 was again strong, and 2023 will be an exciting year with the Bakken returning to a steady growth trajectory, with an active drilling program in the Gulf of Mexico and with the advancement of our major projects and further delineation of the significant upside in Guyana, all of which position us to deliver industry-leading performance and significant shareholder value for many years to come.
I will now turn the call over to John Rielly.
