2016 New Fields

Exploratory drilling has been limited during the year and is strongly affected by the current economic situation and the low oil price. As of end-2016, only 175 discoveries have been reported for a total estimated discovered of 8,560 MMboe 2C/2P EUR volumes. This is the lowest amount of newly added/discovered reserves in ten years.

The graphic below represents the E&P exploratory activities and the number of discoveries made during the period 2010-2016 with regards to the evolution of the oil price:

Discoveries versus Oil Price

The top 10 discoveries of 2016 have all an estimated 2C/2P EUR higher than 185 MMboe. The biggest find made in 2016 is by far the Tulimaniq oil discovery in Alaska; with ~ 2C/2P EUR of nearly 2,700 MMboe, the Alaskan find holds about 30% of the total hydrocarbon volume reported to have been discovered during 2016. Tulimaniq could be potentially the largest North American discovery since 1990 and the 4th largest North American discovery all time (Frontier North America area only).

The Teranga gas discovery offshore Senegal is the only second discovery ranked as a giant (EUR > 500 MMboe) for 2016. The success in Western Africa is further emphasised by the two Angola’s Deep-water Kwanza Basin finds of Zalophus and Golfinho. In the North Sea, the Lincoln Basement find is potentially a large discovery with preliminary pre-drill 3C/3P OOIP estimates of ~ 1,250 MMboe.

At year end, Oil Search and partners announced the discovery of the Muruk gas/condensate field in the remote highlands of Papua New Guinea, although not tested, preliminary interpretation of log data indicated that this gas and condensate discovery is in line with pre-drill prognosis. No hydrocarbon water contact was observed.

Field Projects

Giant Field:

In light of the oil prices evolution since 2014, it is understood that operating companies are focusing their efforts on mature fields in order to improve recovery. Mid 2016, we launched a multi-year global fields project aiming to review all giant (2P EUR >= 500 MMboe) fields and discoveries. Reviews include a total revision of all main field remarks, reserves, development, production volumes and IOR/EOR techniques and will ensure the latest, most up to date information is available.

As of end 2016, a total of some 85 Giant Fields have been fully revised. As part of this project, a total of 3,150 field production volumes and 16,950 HCIP and EUR reserves and resources volumes have been added in the giant fields.

Ukraine Fields:

Following on from a major upgrade of all Ukraine licenses, a full revision of all Ukrainian fields and wells was completed. Using the newly produced licence map and a large set of production figures for most fields in Ukraine (covering period 1960-1993 & 2013-2014) and using various other sources as well as spatial information, the team was able to map wells and field facilities, update and revise reservoirs geology, and revise the field’s reserves and the production volumes.

A total of 5,745 field production volumes and 5,440 EUR and HCIP reserves volumes were entered for more than 220 Ukrainian fields during 2016.

Mexico Fields:

A large production and reserves data set for Mexico fields has been processed during 2016. This data set included the complete annual 2015 production volumes of Oil, Gas and Condensate, it included as well the historical (valid 1st January 2014 and 1st January 2015) 1P, 2P, and 3P Oil, Gas and Condensate in place and recoverable volumes and the most recent (valid 1st January 2016) 1P, 2P, and 3P Oil, Gas and Condensate recoverable and original volumes in place reserves for 761 fields in Mexico (including reservoir detailed split of volumes).

By the end of November 2016, a total of 631 of 764 fields (82.6% progress) have been updated. A total of 860 field production volumes and 12,835 reserves volumes were entered for Mexico fields since the 1st January 2016.

Denmark Fields:

A substantial reserves dataset including all 1P, 2P, 3P EUR estimates for Denmark fields for every year going back to 1985 was processed during 2016 enabling a comprehensive reserves history record for the country.

More than 1,685 field reserves volumes were entered during the year.

Brazil Fields:

More than 353 fields were updated with official reserves volumes including 574 HCIP and 923 EUR reserves volumes.

Field Images

Field illustrations provide additional insight on the field information and include graphic types such as cross-sections, top depth structural maps, seismic interpretations, well logs and stratigraphic charts

  • Worldwide – 168 new field images were drafted and entered and some 227 historic field graphics have been revised or re-drafted

Field Outlines

IHS can provide detailed field outline information for 79% of all fields and discoveries worldwide. The ongoing acquisition of high quality field spatial data has ensured the field outlines are continuously revised and upgraded through a series of regionally-focused spatial projects.

As a result, during 2016, a total of 2,588 new field outlines have been processed and uploaded in the International Field Database. Major updates have been made in Russia (488 new outlines), Mexico (463 new outlines) and Brazil (379 new outlines).

This constant revision ensures that the latest field spatial information is captured and delivered through our web GIS services and our GEPS maps.

Latin America remains the main region with

a total of around 1,181,524 monthly production volumes in the database, followed by Europe (Continental and NW) with some 623,419.

The monthly production database also stores the annual volumes at country level (PEPS). The world yearly production statistics shows that a total of 52,313,006 Mboe were produced in 2015 with the main producing region remaining the Middle East.

Argentina Project – Unconventional wells:

A major project was launched during 2016 following customer requests – we have started to incorporate and report the unconventional hydrocarbon monthly production volumes per well for Argentina. The production volumes are initially extracted month by month and operator by operator, during the process, the relevant unconventional hydrocarbon types are then selected for each well. If the same well is producing from different reservoirs, then a well production entity is created for each reservoir. So far, 1,056 well production entities have been created, the 12 months of 2015 have been successfully uploaded in the International Database, consisting of a total of 29,749 monthly production volumes.

The top ten countries contain some 72% of all reserves volumes stored in the database.

In 2016, a record number of 86,736 volumes (including 5,345 volumes of 1P, 52,090 volumes of 2P and 29,301 volumes of 3P) of individual resource estimates were added to the field database. This represents an increase of 6 % compared to 2015 and a significant increase of 105 % compare to 2012-2013 field/reservoirs reserves entry rate.

The field reserves and resources data entry level reached this year makes 2016 a whole-time record year in terms of fields and reservoirs reserves/resources entered into the International Field database.
