Rocksource was a technology-based exploration and productionpetroleum company listed on the Oslo Stock Exchange. The company was established as a partnership between Norwegian entrepreneurs, oil industry professionals and academics, Jonny Hesthammer and John Howell from the University of Bergen. The company focused on two areas. For exploration the company developed algorithms for the processing of Controlled Source Electromagnetic (CSEM) data which were used as part of an integrated exploration process. Secondly the company successfully exported "North Sea style" reservoir management techniques to the highly conservative onshore gas fields of east Texas where it bought old oil and gas fields and revitalized them.
Rocksource built up a portfolio of exploration acreage that was suitable for de-risking using CSEM. The first tranche of wells were drilled in 2011 with mixed results, including a marginal discovery in the Barents Sea. The results were perceived negatively by investors and the share price fell sharply. The subsequent discovery of the Pil and Bue fields in 2014 saw the company as successful but underfunded. This led to the company being delisted and purchased by Hitech Vision. Rocksources was combined with other Hitech companies to create Var Energi.
North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea.
Snøhvit(English: Snow White) is the name of a natural gas field in the Norwegian Sea, situated 140 kilometres (87 mi) northwest of Hammerfest, Norway. The northern part of the Norwegian Sea is often described as the Barents Sea by offshore petroleum companies. Snøhvit is also the name of a development of Snøhvit and the two neighbouring natural gas fields Albatross and Askeladden. Estimated recoverable reserves are 193 billion cubic metres of natural gas, 113 million barrels of condensate, and 5.1 million tonnes of natural gas liquids (NGL). The development comprises 21 wells. The Snøhvit development is operated by Equinor on behalf of six gas companies owning licenses:
Ekofisk is an oil field in block 2/4 of the Norwegian sector of the North Sea about 320 km (200 mi) southwest of Stavanger. Discovered in 1969 by Phillips Petroleum Company, it remains one of the most important oil fields in the North Sea. This was the first discovery of oil after the drilling of over 200 exploration wells in the North Sea "triggered" by the Groningen gas field discovery. In 1971, Phillips started producing directly to tankers from four subsea wells. Oil production is planned to continue until at least 2050.
Oseberg is an offshore oil field with a gas cap in the North Sea located 140 km (87 mi) northwest of the city of Bergen on the southwestern coast of Norway. The field, which is 25 km long by 7 km wide, was discovered in 1979 and its development is known to be one of the significant milestones in emergence of Norway's independent oil and gas industry. The Oseberg field was named after Oseberg ship, one of Norway's most significant archeological discoveries. The ancient Viking ship from the early 9th century was discovered in a 1904 historical excavation of a burial mound at the Oseberg Farm, south of Oslo.

The Canadian petroleum industry arose in parallel with that of the United States. Because of Canada's unique geography, geology, resources and patterns of settlement, however, it developed in different ways. The evolution of the petroleum sector has been a key factor in the history of Canada, and helps illustrate how the country became quite distinct from her neighbour to the south.
The exploration of the Arctic for petroleum is considered to be quite technically challenging. However, recent technological developments, the melting of Arctic permafrost, as well as relatively high oil prices, have allowed for exploration. As a result, the region has received significant interest from the petroleum industry.

The controlled source electromagnetic (CSEM) method, also called sea bed logging, is a mostly offshore geophysical technique, employing electromagnetic remote-sensing technology to map the electric resistivity distribution of the subsurface. The electrical resistivity helps to discriminate between different types of rocks. CSEM is mostly used to indicate the presence and extent of hydrocarbon below the seabed.
Canada's early petroleum discoveries took place near population centres or along lines of penetration into the frontier.
