Makó gas field
natural gas field in Hungary

The Makó gas field (Makó Trough of the Pannonian Basin Gas Accumulation) is a large natural gas field next to Makó, in southeastern Hungary.
Formation
The worldwide interest in unconventional hydrocarbon accumulations has increased continuously because of a growing demand for natural gas and the availability of a growing range of advanced oilfield technologies. For these reasons, the thermally mature, shaly sediments of the deep Makó Trough of the Pannonian Basin have become a new target for exploration companies looking for unconventional natural gas resources.
Research
Since the 1960s it was well known that a large gas field existed next to Makó. The disadvantages are the depth of the gas deposit at about 5,000 metres (16,000 ft) as well as the very high pressures and temperatures, the large thermal increase with depth in Hungary about 20 metres (66 ft) per degree Celsius compared to a world-average 50 metres (160 ft) per degree Celsius).
In the late 1980s, the World Bank funded a deep drilling program in Hungary, led by the American Geological Survey. An American geologist, John Gustavson, noted in the survey data that he obtained a research permit in 1998 for part of the Makó Trough. Later Marc A. Bruner bought the concession from him, who founded the Canadian-based Falcon Oil & Gas Ltd.
At the 90% probability rate, Makó had certified recoverable resources of over 600 billion cubic metres (21 trillion cubic feet) of natural gas, according to a report by the Scotia Group, prepared for the field's exploration concession holder, the Falcon Oil and Gas. Later estimates rose to about 1,550 billion cubic metres (55 trillion cubic feet) of natural gas.
“Makó gas field” enters the record as natural gas field in Hungary. Crown Archives preserves that source wording while asking what Makó, field and natural can confirm, complicate or overturn.
Why this record matters
“Makó gas field” is worth following because a concise public description often conceals a longer documentary argument. Here, Makó, field and natural provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q6740521. Authority coordinates are 46.215, 20.476. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1998.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
