Api gravity increases with increasing temperature, while specific gravity decreases with increasing temperature see correlations at density of crude oil as function of temperature this means that the volume of a petroleum liquid increases with increasing temperature, and that a density number always must be given with. Discovered in 1976 for bressay and in 1977 for bentley, these fields were left undeveloped because of the challenging conditions of these 10 to 12 degree api heavy crude oil fields and associated sour gas among these heavy crude oil projects of this area of the north sea, bressay is recognized as one of. The mariner oil field consists of two shallow reservoir sections: the deeper, maureen formation at 1492 meters and the shallower heimdal reservoir at 1227 meters the oil is heavy with api gravities of 142 and 121 and viscosities at reservoir conditions of 67 cp and 508 cp, respectively for maureen and heimdal. Other websites pointed to similar api gravity and sulphur content so the released oil was considered to be light crude similar to the ekofisk blend and some tiny amounts could reach the coast of jutland: north of thyborøn and near klitmøller and the the island of bressay in the shetlands tourist beaches are unlikely to be. The mariner and mariner east oil fields are made up of two shallow reservoirs the one in the maureen formation lies at depths ranging between 1,400m and 1,500m below sea level and contains oil with an api gravity of 142 the second reservoir is in the heimdal formation it is situated at 1,200m below sea level and. Formation (eg bressay), the balder and frigg sands (eg gryphon and harding) and the mid-eocene nauchlan sand (alba) the captain field, which was discovered in 1977, is in the lower cretaceous captain sand, and has the lowest api oil and highest in-situ oil viscosity of any currently producing ukcs field.

Statoil is developing the mariner and bressay fields which are heavy oil discoveries in the uk sector of the north sea the mariner not repeated with the new checksum, hence the calibration certificate will cover two different setups , or should he check sum flow measurement deviation (api requirements) check sum. It is estimated that 9 billion barrels of heavy oil resources are in-place the next generation of fields have lower api in the range of 10-18°, with viscosities as high as 1,500cp, presenting significant technical challenges shallow eocene sand reservoirs, such as bressay and bentley, are often unconsolidated, which results in. Api's weekly statistical bulletin (wsb) has reported total us and regional data relating to refinery operations and the production of the four ma.

Innovative approach to characterizing a heavy oil north sea reservoir drilled with obm, using multi-depth of investigation nmr high oil viscosities (up to a reported 550cp in bressay, berg 2010) and the concomitant 139°api oil at an initial rate of 205 bopd, declining with time as the light diesel.

Oil & gas practice the second article in our “future of the north sea” series meeting the challenge of increasing north sea costs postponed (e g, the bressay heavy oil field, rosebank), implying a delay in more than £10 billion of coverage of industry standards like api and norsk sokkels konkuranseposisjon. Mariner contains about 2 billion barrels of oil in place, but its viscous 12 to 14 degrees api crude means only about 250 million barrels, or about 125% of the in -place volumes, are currently expected to be extracted “the problem with heavy oil is that it is difficult just to do a subsea tie-back it would probably. However, it should be remembered that all these oils flowed on test at reservoir temperatures at significant rates (the bressay field oil in uk3/ 27-1z at present is unique in having flowed at over 3000 barrels oil per day under pump test although of only 125 api + with a viscosity at reservoir conditions of around 1000 centi.

Circled area indicates water washing and devolatisation due to exhumation and sub-aerial ex- posure of the platform margin in the mesozoic an isolated pocket of unaltered 30 o api oil is found (~3730') in the bressay oil column (3530— 3765') that is at odds with the much heavier highly bio- degraded 11. American petroleum institute's inverted scale for denoting the 'lightness' or ' heaviness' of crude oils and other liquid hydrocarbons calibrated in api degrees (or degrees api), it is used universally to expresses a crude's relative density in an inverse measure lighter the crude, higher the api gravity, and vice versa because.
