Marine drilling activity in the Black Sea began on August 19, 1976, when the "Gloria" platform came into operation, it being located at a distance of 72 Mm East from Cape Midia, at a maximum water depth of 90 m. The first placement was in place 1 Ovidiu Est, the final depth achieved being 5,006 meters.

The next drilled wells were 12 Midia, (depth: 4,226 m) and 8 Lebăda Est (depth: about 3,000 m).

The first discovery of hydrocarbons took place in 1980. Hundreds of drillings were carried out, so that on May 7, 1987, at 16:45, the marine oil field that was exploited by "Petromar" Constanţa was penetrated. This is how the first information on the existence of oil and gas hydrocarbons from the Cretaceous geological era was obtained (the Cretaceous or the Cretaceous period represents the last part of the Mesozoic era, which succeeds the Jurassic, characterized by massive limestone deposits; it began about 150 million years ago ago and ended about 65 million years ago).

According to the news published in the mass media, during 2008, S.C. "Petromar" S.A. Constanta has significantly reduced its oil extraction from the "Histria" block (it includes the "Lebăda Est", "Lebăda Vest", "Sinoe" and "Pescăruş" deposits), from 1,500 tons/day (in 1997-1998 ) to over 800 tons (in 2008), the cause of this decline being the gradual depletion of existing resources in the deposits; instead, in the same area, the amount of extracted natural gas increased, and by December 2008, "Petromar" was to start exploitation near the Gura Portiţei landmark, at the "Neptun" oil block ("IV Delta" field). , hoping to obtain from that area 200-400 tons of fuel per day; the specialists estimated that the Constanta company would reach a constant level of daily production of 1,000-1,200 tons of oil, which would allow maintaining an annual production of over 10 million barrels of crude oil equivalent.

Simultaneously with the digging of the wells on the Lebăda Est structure (exploitation wells), "Gloria" was transformed into an exploitation platform, a situation existing in December 2010 (ensuring the exploitation of the wells on the Sinoe structure).

In the fall of 1982, the "Horizon" platform was put into operation, with which it was possible to locate the first quantities of oil and gas of economic interest (from the Albian geological era - the first floor (age) of the Middle Cretaceous, considered the last floor of the Lower Cretaceous) .

The following offshore drilling rigs came into operation as follows: 1984 - "Prometeu", 1985 - "Fortuna" (currently - December 2010 - named "Oriental 1" (name changed after sale)), 1986 - "Atlas" , 1987 - "Jupiter", 1988 - "Saturn" (all seven Romanian platforms were built in the Galati Naval Shipyard, starting in 1975; at the end of 2005, being in the patrimony of the "Petrom" company, six of the seven platforms have were sold to the company "Grup Servicii Petroliere", at "Petrom" only the "Gloria" platform remained in operation; the other platforms ("Orizont" and "Atlas") were located in the Persian Gulf, "Saturn" was located along the coasts of Romania , and "Prometheus" was near the coasts of Turkey).

The commissioning of these platforms meant the continuation of the drilling activity in the continental plateau of the Black Sea (shore of our country), making wells with depths between 2,000 m and 4,500 m.

At the same time as the drilling of the first exploitation and injection wells, the directional drilling activity was carried out, which led to the creation of inclined wells (30° - 60°) and horizontal wells (still made today).

In 1993, the construction of wells for external partners began (with the "Prometeu" platform in the Şabla area - Bulgaria).

Wells were dug with the "Orizont" platform in the Sea of Marmara, in the Eastern Mediterranean, in the Persian Gulf, after which, in 2000, it was upgraded to a Cantilever type platform (in the Lamprell shipyard).

The "Fortuna" platform drilled in the Sea of Marmara, after which it was transported to the Lamprell shipyard and upgraded to a Cantilever type platform.

From the spring of 2001, these platforms were moved to areas in the Persian Gulf, where they operated until November 2004 ("Fortuna") and January 2005 ("Horizon") - currently (December 2010), the platforms "Horizon" and " Fortuna" operates for foreign beneficiaries.

The "Atlas" platform, after performing some services for a foreign partner, was taken to the Aegean Sea, where it also carried out soundings, going to the Persian Gulf, in order to be upgraded to a "Cantilever" type platform.

This intensification of the drilling activity for external partners was possible thanks to the efforts made to equip and modernize the platforms with high-performance equipment, worldwide (mud pumps, devices for screwing/unscrewing rods, drilling air compressors, equipment for tracking drilling parameters , performance tools and devices, gels, shock absorbers, milling cutters, knives for cutting columns, etc.).

Sister platforms: "Horizon" (1981 - Galati), "Fortuna" (March 1985 - Galati), "Prometheus" (October 1985 - Galati), "Atlas" (October 1985 - Galati), "Jupiter" (July 1987 - Galati ), "Saturn" (August 1988 - Galati).

Oil was exploited in the Roman province of Dacia, now in Romania, where it was called picula.The beginning of the Romanian petroleum industry dates back to 1769 with the documentation of rudimentary crude oil extraction in Moldavia by Dimitrie Cantemir, a former Moldavia King, who published the account in "Descriptio Moldavie."The first documents attesting the existence of fuel oil on today’s territory of Romania do not tell us, however, how oil was extracted or what it was used for. Fuel oil is only mentioned in passing, as a mere topographic detail. The first document from the Romanian historical province of Moldavia is dated October 4th 1440, while the first records mentioning oil from Wallachia is dated 1517.In the beginning, crude oil exploitation simply meant collection from the shallow pits and ditches in the outcrops of the Sub-Carpathian area. The technique involved digging small holes into the ground, where fuel oil was collected, while the crude oil was channelled through ditches towards a collecting pit. The exhaustion of these so-called outcrops led to the in-depth exploitation of the crude oil by means of technologies taken over from other industrial sectors. The so-called “oil bath”, for example, was imported from the coal industry, and was used extensively from the late 16th century to the 19th century. Fuel oil washeries were used at the same time. Some progress was made when pits started to be dug, in square and circular shape depending on the depth of the oil field. In our country the first processing equipments of petroleum are considered the “oil pumps” from Lucacesti-Bacau, belonging to N. Choss in 1840 and M. Heimsohn in 1844. Distillation on industrial way starts with the refinery built by Mehedinteanu brothers at the periphery of Ploiesti city, near the South Station, on 174, Buna Vestire Street. The refinery installations were quite primitive, all the equipment being build up from iron or raw iron cylindrical vessels, warmed up directly with wood fire. This equipment was ordered in Germany from Moltrecht company which was building boilers for bituminous shale distillation. Industrial distillation was a technology first used by a refinery built by the Mehedinteanu brothers, on the outskirts of Ploiesti, in southern Romania. The equipment consisted of cylindrical cast iron recipients, under which a fire was lit. The equipment was ordered from a German company making bituminous schist boilers. The building of the so-called “gas factory” started in 1856, and was commissioned by Marin Mehedinteanu.

Romanian oil production between 1857 and 1930

The Romanian reservoirs range from 100 to 4800 m in depth and a thickness of a few meters to tens of meters. The reservoir rocks consist of sandstones or limestones which are continuously layered with oil gravities from 14 to 37°API. Natural water encroachment has been hindered by strong folding and faulting. The major reservoirs are in the Moesic Platform, the Meridional or Eastern Carpathian Depression, the Pannonian Platform and the Continental Shelf of the Black Sea. The reservoirs are of different ages, from the upper Pliocene (Levantine) to the lower Triassic.

1908 - The first well was drill in search of gas at Sarmasel-began on February 9, 1908 and was stopped on day 8October 1908, at a depth of 627 m, due to technical difficulties. On this occasion found that the formations had crossed a slope of 470, leading, following calculations, the hypothesis that potassium-rich salt waters may be encountered at a depth approximately 1000 meters. To verify this hypothesis, another location was chosen to a distance of 2.9 kilometers N-E first. Thus, on the November 26, 1908, start drilling probe 2 Sarmasel.During well drilling , at a depth of 122 meters were observed first emanations of gas, as the depth grew and became increasingly violent.

Thus, at a depth of 228 meters was intercepted a deposit so strong that contractor was forced to stop work because of high gas pressure. After have taken necessary safety measures, the probe continued digging until 22 April 1909, when work is stopped due to a strong and permanent gas eruptions, which dropped out of the drill rigs rolling. Depth probe at that time was 302 m, and the flow was measured to 1,000,000 m3/day, the gas pressure was estimated at 41 bar. In Following this event, founded in Cluj State Service for mining, which have the object of study of natural gas deposits discovered in Sarmasel.

1937 - The gas extracted of the Meotian Margineni condensed gas field is reinjected to maintain the reservoir pressure.

1937 - The maximum interwar drilled wells was registered in 1937 with 394 000 meters dug. Comparing to 1921, when the number of drilled meters was 55 857, the rise was more than 700 percent.
1938 - During the 1930s the engineer Dr Ion Basgan was the first to introduce sonic vibrations in the drill pipe string of a conventional rotary drilling rig. The sonic currents caused the steel pipe string to oscillate up and down and thus to produce powerful blows on the bottom of the borehole through the rotating drill bit. This enabled the depth and speed of drilling to be greatly increased. It also enabled the drill to bore a truly vertical hole without distortion, which was not always possible with the old method. For example, at the Moreni oil fields in Romania in 1938 a bore hole was drilled 1,915 metres (6,300 feet) deep in 30 days by this method.

All wells were connected by pipeline company between them and the refinery "Aquila" of Ploiesti, on a charge of Society of Băicoi station, where they were and static tanks, and pipe oil towards Giurgiu. The total length of pipeline was 150 km. These pipelines annual carrying over 500,000 tonnes of petroleum products or company, or other companies. May had 386 wagons (163 own and 223 leased) for transport petroleum products from refinery company to export station Constanta.

1942 - Oil and gas production is governed by the "Petroleum Law".
1945 - The set up of Sovrompetrol Company. After 1944 “Colombia” was included in “Sovrompetrol”and the entire activity was intended to serve the Soviet interests. Under the new circumstances, in June 1948 the company was dissolved.After World War II, Romania nationalized the oil industry, which until then had been owned largely by foreign interests. Under Communist rule, massive investments in the petroleum and petrochemical industries were made in the drive to modernize.

1946 - Smoke pours from high stacks over the oil refineries at Ploiesti,Romania,indicating resumption of oil refining at the field,target of numerous low-level atacks by americans and british bombers in 1943.Annual production at Ploiesti now reaches 6 000 000 barrels.

1961 - This year represented the beginning of drilling for deep exploration in Romania starting with the 900-Boldesti well at 4865 meters. Between 1963 and 1966 the company Foraj Sonde Ploiesti (FSP) - formerly “Concordia” finished the following exploration wells: 10-Tinosu (6016 meters), 913-Margineni (6002 meters), 5015-Baraitaru (4984 meters), 6003-Podeni (5985 meters), 4503-Bratesti (5414 meters).

1963 - The deepest oil well was drilled in Ticleni,the core of oil production in Oltenia.The well held a long time the Europen record - 6016m

1964 - Application of steam injection at Moreni(Levantine) and in situ combustion at Suplacu de Barcau(Pannonian) reservoirs. Due to its performances (production being maintained at the same level for over 25 years and a recovery factor of 56% in the area swept by the front), Suplacu de Barcåu remains the singular in situ combustion process in the country.

1965 - Romania was the first country in Europe to build a natural gas compressor station, placed on a main pipeline and provided with turbo-compressors, in Batani.

1965 - The well 504 Corbii Mari was drilled.Since then, the well is in eruption. It never required any intervention or capital reparation.

Ploiesti,Romania-drilling for oil in 1966.

1974 - A national programme for increasing oil recovery is created.The first gas deethanizer station was built in Pitesti.

1975 - The first offshore drilling platform is set on position on the continental platform of the Black Sea.Output for first time in Romania an offshore drilling platform, which would be a facility is equipped with drilling made at May 1 Company in Ploiesti also necessitated the purchase of a license was contracted, ultimately, the American company "Offshore Co.. This company offered part of project financing, delivery system hydraulic lifting platform (patent themselves), technical design, technical supervision over the execution platform, training romanian personnel (engineers, foremen, the probe heads, mechanics, electricians). Construction drilling platform in Galati shipyard place under the technical supervision of the register of shipping American (American Bureau of Shipping). At the same time work began planning the berth 34 in port of Constanta and helicopters base at Tuzla. In May 1976 the construction of platform was completed and went on deck GLORIA Danube to Constanta. After the bar the Sulina was passed with great excitement due to wind and cross current conflict with great platform reached the port of Constanta on May 26, 1976. The Dana 34 was welded remaining sections of the foot platform and have been checking the latest challenges and technological tests. The platform was carried on, the first location, Well 1 Ovidiu East, where depth water was 84 m (platform was designed for maximum water depth of 90 m and maximum wave height of 12 m). Since the first year successfully supported platform storm waves of 10-11 m and wind speeds of 40-45 m / sec. The well reached a depth of 5006 m, collected a material rich geological information, but economically it was a sterile probe. A second borehole was drilled on structure Midia to a depth of 4000 m, where he encountered dificult major drilling (massive loss of movement). Of economically and that the second drilling proved sterile. This has led to the third location, the structure Swan (location 8 Swan), in an area with sea water depth of 50 m, located next to Lake Razelm, ca 80 km N-E of Constanta. In nine fall 1979 begins an era in Romanian oil history, for the depth of 2500 m, upper Cretaceous limestone formations, there were first signs of oil,which immediately made tests confirmed the presence of crude oil in significant quantities.
Thus began exploiting oil in the Black Sea ...

1976 - Peak production was reached in 1976, gradually declining in subsequent years, as many of the country's 200 oil fields began nearing depletion and discovery of new reserves waned.Despite an accelerated exploration program, with average drilling depths increasing to 8,000 to 10,000 meters, oil output declined from 308 barrels per day in 1976 to 227 in 1986.

1979 - Increasingly large quantities of crude had to be imported, and in 1979 imports surpassed domestic production for the first time. The 10th World Petroleum Congress is held in Bucharest.
1979 - First underground gas storage.
1984 - 7000 Baicoi well reaches a depth of 7025 m.
1987 - The first offshore oil production starts.
1987 - The first offshore water injection process is initiated.

1988 - Seven offshore oil-drilling platforms were operating in the Black Sea under the supervision of the Constanta-based Petromar enterprise to develop hydrocarbon reserves in the continental shelf.
1993 - The SPE Romanian section is set up.
1995 - The National Agency for Mineral Resources is founded and the new Petroleum Law comes into force.
1997 - The set up of the National Oil Company Petrom S.A.
2004 - Petrom becomes a member of the OMV Group.
