April 2026 was marked by a series of major events in oil and gas exploration worldwide. Companies and governments are announcing new deposits one after another, launching large-scale tenders, and confirming the potential of previously discovered fields. The trend toward intensified geological exploration that emerged in recent months continues to gain momentum.
The main news of the month came from Brazil. BP estimated recoverable resources at the Bumerangue field at 8 billion barrels of oil equivalent. This is the largest hydrocarbon discovery in the past 25 years. The field is predominantly gas condensate: the gas cap reaches 900 meters, while the oil rim is approximately 100 meters.
Russia was not left behind either. On April 21, Gazprom Neft announced the discovery of two new deposits at mature fields in the Khanty-Mansi Autonomous Okrug. The total geological reserves of the new formations exceed 4 million tons of oil. The deposits were identified at sections of the Yuzhno-Priobskoye and Orekhovo-Yermakovskoye fields at depths exceeding 3 kilometers. The first wells produced stable flows of water-free oil: 100 tons per day at Yuzhno-Priobskoye and 90 tons at Orekhovo-Yermakovskoye. The discovery was made possible by a Russian digital geological data analysis system.
Indonesia decided to attract global investors. The Ministry of Energy and Mineral Resources announced a tender for 116 new oil and gas blocks. The government aims to achieve oil production of 610,000 barrels per day and strengthen energy sovereignty. The decision was reinforced by the successful drilling of the Geliga 1 well in the Kutai Basin, where gas reserves of 5 trillion cubic feet (approximately 142 billion cubic meters) and 300 million barrels of condensate were identified.
Algeria also presented investors with a portfolio of 24 onshore blocks in the Sahara. Of these, 13 relate to development projects (may require enhanced oil recovery methods), and 11 to exploration projects, some of which already contain discovered fields. The initiative is being implemented as part of Sonatrach’s capital investment program of $60 billion for 2026–2030 and complements the previous tender for 7 blocks.
Finally, Kazakhstan released the results of a comprehensive analysis of oil and gas potential in deep Paleozoic deposits of the Caspian Basin. The study confirmed a high probability of large hydrocarbon accumulations at depths exceeding traditional exploration zones. In 2025, liquid hydrocarbon production in Kazakhstan reached 99.4 million tons, with two-thirds of the volume coming from three giants—Tengiz, Karachaganak, and Kashagan.
Thus, the spring race for hydrocarbons continues. Companies and countries are increasing investments in exploration, discovering new deposits, and offering blocks to investors. The oil and gas industry remains attractive even amid the energy transition, and new technologies enable resource discovery where they were previously unseen.
