Adjacency: Block XX lies at the southern end of the Tamsag Basin, which is historically the most productive part of Mongolia and contains Block XIX to its north.
Shared resources: The Heron structure, where Block XX's discoveries were made, actually extends from the northern part of Block XX into Block XIX. This means that the petroleum system is continuous across the boundary of the two blocks.
production volumes from Block XIX are not publicly specified, but recent reports from neighboring Block XX give an insight into operations in the region. In 2017, the operator of Block XIX, PetroChina Daqing Tamsag, was reportedly producing around 21,000 barrels of oil per day (bpd) from its fields, which include Block XIX
