One way to decrease the cost and time of seismic data acquisition is to design sparser surveys by decimating the number of shots and receivers used. The tradeoffs associated with such decimations are investigated further here, using ocean-bottom node (OBN) data from a complex geological setting in a pre-salt play of the Santos Basin, offshore Brazil.

ExxonMobil, with partners TotalEnergies, JHI and Mid Atlantic, have come up dry again on the Canje Block, offshore Guyana.

Mexico’s Tampico-Misantla Basin is potentially one of the richest unconventional oil and gas resources in the world. The development of these resources could significantly increase Mexico’s daily production of oil and gas, and bring in enough income to rejuvenate the national oil company, PEMEX, and help get the economy back on its feet.

ExxonMobil and partners Hess and CNOOC made another oil discovery offshore Guyana; encountering 36.7m of oil in Cretaceous sandstones in the Uaru-2 wildcat well on the prolific Stabroek Block.

Tullow’s Block 47 GVN-1 has reached TD at 5,060m, encountering good quality reservoir but only minor oil shows.

Apache and Total have encountered considerable net hydrocarbon pay in good quality Upper-Cretaceous reservoirs in the Block 58 Keskesi East-1 well.

In southern offshore Trinidad, BHP have made two deepwater gas condensate discoveries in recent years, but the latest Broadside-1 well was met with disappointing results.

Late in 2020 Brazil announced details of its 17th Licensing Round in which 92 blocks in the offshore Campos, Pelotas, Potiguar and Santos Basins, covering a total of 53,900 km2, will be offered.

Suriname is offering eight new offshore blocks in the underexplored Shallow Offshore (SHO) acreage, which are in close proximity to a string of deepwater hydrocarbon discoveries and billion barrel in-place onshore oil fields.

Petronas, with new farminee ExxonMobil, have now spud Sloanea-1 on Suriname Block 52, along trend and 60 km south-east of Kwaskwasi in Block 58.

Since August 2019, Touchstone Exploration of Canada have been quietly logging impressive net gas pays and proving up significant gas reserves in Trinidad’s mature southern onshore trend.

New pre-salt hydrocarbon opportunities have been identified in the ultra-deepwater areas of the Santos Basin.

Multi-client geoscience provider Searcher offers Argentina Explorers Package, which includes seismic and well data, to support oil and gas exploration in the onshore Neuquén and Cuyo Basins in the Mendoza province of Argentina.

Patterns are emerging in the Guyana-Suriname hydrocarbon hotspot as further successes are announcement - indicating an even more promising future for oil and gas exploration in the region.

Reprocessing of seismic data across the Malvinas Basin has increased the hydrocarbon potential offshore Argentina by defining virtually unexplored Tertiary plays.
