exploration and development, allocated China seas with

priority and balanced the mature zones, rolling zones and

new zones, and concentrated on overseas high-quality

blocks and conventional oil and gas resources. Meanwhile,

the Company deepened the idea of value of exploration,

with the main line of seeking large- and medium-scale oil

and gas fields, properly reduced the ratio of high risk and

high investment wells, and guaranteed the medium- and

long-term sustainable development with relatively high

workload. Furthermore, influenced by the sharp decrease

of international oil price in 2016, the Company maintained

a reserve replacement ratio of 8%, which was 145% after

eliminating economic correction.

CNOOC always puts oil & gas exploration and development high on its agenda in an innovative manner to stabilize and further its business development. Guided by the idea of “seeking for new medium and large-scale oil & gas fields”, CNOOC makes extensive breakthroughs in the oil & gas exploration both at home and abroad, and takes the initiative to fulfill the responsibility of supplying oil & gas so as to continuously satisfy people’s ever-increasing consumption demands for petroleum and natural gas.

2D and 23,980 square kilometers of 3D seismic materials

overseas. In 2016, there were 2 new discoveries in overseas

exploration and 6 successful ratings of hydrocarbon-bearing

oil and gas structures. The main achievements include:

l Successfully explored 5 appraisal wells in the Libra

Project in Brazil, further confirmed the reserve scale.

l Liza Oilfield in Guyana was successfully rated, which

expanded new bed series and reserve scale; Payara

Structure was successfully pre-explored again.

l The exploration of Owowo West Structure in Nigeria

achieved great success and was rated to be a large-scale

uncompartmentalized oil and gas reservoir, which improved

the economic value of this region.

In 2016, the Company insisted on the idea of “improving

exploration management” overseas, continued to optimize

exploration asset portfolio and successfully transferred part of

the rights and interests of overseas blocks while gaining the

new exploration opportunities, which brought more benefit for

the Company.

The Company kept being improved in exploration deployment

optimization, operation cost reduction and management

In China seas, the exploration workload of the Company

continued to be fully achieved. 115 exploration wells were

explored. In addition, 17 unconventional wells were completed

in China onshore. In 2016, 2,471 kilometers of 2D seismic

materials were collected under self-operation, and 11,347

square kilometers of 3D seismic materials were collected under

self-operation and foreign cooperation. The Company achieved

12 new discoveries in China seas and successfully rated 19

hydrocarbon-bearing structures. The success ratio of self-

operation well exploration in China seas reached 52%-69%.

In 2016, the Company continued to conduct active exploration

strategies in China seas and led to abundant achievements,

which mainly include:

efficiency increasing. In addition, the Company further

improved the operation efficiency and reduced exploration

cost by strengthening geological study, improving operation

standards and refining the operation links.

Development and ProductionIn 2016, the Company completed the production goal and

the oil and gas output reached the target set at the beginning

of the year. The Company organized operation resources

and the construction went on well. Under the precondition of

safety production, the development and production operation

of the Company completed the annual development and

production goals centered with cost reduction and efficiency

enhancement.

In 2016, the Company produced 76.97 million tons of crude

oil and 24.5 billion m3 of natural gas (including CBM). Among

which, the domestic crude oil production was 45.55 million

tons and natural gas was 12.92 billion m3, while the overseas

crude oil was 31.42 million tons and the natural gas was

11.57 billion m3. The four new projects planned to be put into

CNOOC 2016 ANNUAL REPORT BUSINESS

l Continued to keep high production efficiency through

delicacy management.

l Consistently carried out special management on

operation expenses, and notable result was achieved. The

operation cost per barrel was decreased to 7.62 USD/boe

which is the third consecutive year of oil price decrease.

l Deeply optimized the technological plan for the

development projects and achieved notable result in cost

reduction and efficiency enhancement.

l Decreasing the equipment and facility breakdown rate

through the deep implementation of integrity management.

Unconventional GasAccelerat ion of the development and ut i l izat ion of

unconventional gas is of great strategic significance for

energy structure optimization and energy supply guarantee.

The Company tracked and researched the new development

trend of unconventional gas in the whole world, meanwhile,

based on the development idea of “develop CBM, tackle

tight gas, explore shale gas”, the Company insisted on the

principle of “integration of exploration and development,

integration of production and sales, integration of self-

operation and external cooperation, integration of tight gas

and CBM” to promote the exploration and development of

unconventional gas.

Relying on the technology advancement, the Company

continued to intensify exploration and development,

accelerated the development of unconventional gas industry

and strived to create a new growth potential. Following

the guideline of “focusing on the key blocks to explore

and invest”, the domestic unconventional exploration was

focused on tight gas, and the new bed series exploration has

made breakthroughs in new zones. The tight gas reserves

and production was increased, CBM production was

stabilized and accelerated, the unconventional gas output

continued to grow. Part of the well exploration and production

integration in Linxing tight gas pilot test zone was advanced

where exploration, fracture and operation were realized in the

same year, and the daily output of wells in operation reached

over 200,000 m3, forming a rapid operation model where

a combination of pipe gas sale, LNG sale and medium-

pressure tank wagon is seen, which accumulated benefiting

experience for the economic and high-efficiency exploration

and development of tight gas. Notable results were also

achieved in CBM exploration and development. North blocks

in Shizhuang applied hydrodynamic wave and fracturing

technology to shorten the gas breakthrough time, which built

foundation for the construction of integration experimental base

for the next step. Panhe Demonstration Project increased over

50,000 m3 of daily output through the initiation of booster

station compressor helical-lobe compressor equipped with

border group valve and other measures. South region in

Shizhuang South Project achieved the first CBM exploration

permit and two gas gathering stations were built and on trial,

which enabled the export sales for the CBM in this region,

and projects in Liulin and Zaoyuan have been promoted

smoothly as planned. In 2016, the Company realized CBM

utilization equivalent to 940 million m3, increasing by 7.8%

compared to that of last year.

In 2016, there were changes in the demand and supply

of global natural gas, and the price of natural gas was

sharply decreased, which brought extreme challenge to the

profitability of unconventional gas. The Company confronted

the challenge and carried out comprehensive coping

strategy. Sales strategy has being constantly optimized,

the connection between production and marketing was

strengthened, and the online transaction was expanded.

Insisting on benefit making by scientific research, one

scientific research project and one demonstrative project

independently undertaken by the Company were approved

by the government. The idea of “win-win” in foreign

cooperation has won great support, which efficiently

promoted the progress of cooperation projects and achieved

the income and benefit growth.

GLOSSARY

Drilling Platform

Offshore drilling platforms are marine structures used mainly for drilling exploratory wells. Such platforms, generally divided

into mobile and fixed platforms, are essential for offshore oil & gas exploration and development operations and house drilling,

power, communications, navigation and other equipment, as well as lifesaving and accommodation facilities.

Heavy Oil

Heavy oil is highly viscous crude oil that contains a relatively high level of asphaltenes and resins. This usually refers to those

with ground densities greater than 0.943 and underground viscosities greater than 50 centipoises.

Oil Reservoir

This is the smallest unit for the storage of oil. Oil reservoir layer or oil layer in short refers to the porous strata for the storage of

oil. Not every part of an oil layer will contain oil. Oil reservoir refers to those independent oil-containing areas within an oil layer.

Exploratory Well

Exploratory wells refer to wells drilled within an oil or gas field for acquiring the necessary geological data to determine the

existence, delineate the boundaries, and perform industrial evaluations of oil or gas reservoirs. Those drilled during the

exploration phase can be further divided into prospecting, preliminary exploration and detailed exploration wells.

Adjustment Well

Adjustment wells refer to scattered or clustered wells drilled, in addition to existing well clusters, for improving the development

of oilfields.

Well Logging

Well logging usually refers to geophysical well loggings, in which different forms of well loggers made based on electrical,

magnetic, acoustic, thermal, nuclear and other physical principles, enter wells through the use of well logging cables, to allow

the ground electrical measuring instruments to record continuously along the well bore the various parameters that change

with changes in depth. Underground rock formations, including oil, gas, water, and coal layers and metal deposits, can then be

identified through curves representing these parameters.

Fracking

Fracking, also known as hydraulic fracturing, refers to a technique used to create fractures in the oil layer using hydraulic

pressure. The process involves the use of a fracking device, to inject a large volume of viscous fluid under high pressure into the

oil layer and then fill the resulting fractures with proppants such as quartz sand to increase the permeability of the oil layer and

in turn, increase the amount of water injected or oil produced.

CNOOC 2016 ANNUAL REPORT GLOSSARY

Oil Spill Response

Oil spill response is the formulation of plans and adoption of measures to control and prevent oil spills and reduce pollution

damage, based on the environment and resources in the potential spill sources and waters within the designated sea areas.

This sees common use in offshore oil exploration and development activities.

LNG

Liquefied natural gas or LNG in short refers to the liquid that forms when natural gas extracted from gas fields cools to a

low temperature under high pressure after undergoing the fluid and acid removal, drying and distillation processes. LNG is

predominantly methane and is colourless, odourless, non-toxic and non-corrosive.

QHSE

The abbreviation QHSE stands for Quality, Health, Safety and Environmental. Established based on the principles of

compatibility of similarities and complementarity of differences, and on the basis of the ISO 9001 and ISO 14001 standards,

GB/T 28000 family of standards and SY/T 6276 Petroleum and Natural Gas Industries – Health, Safety and Environmental

Management System, the QHSE management framework usually refers to the framework that directs and controls the quality,

health, safety and environmental aspects of an organisation.

Coalbed Methane (CBM)

Coalbed methane, which is a coal-associated mineral resource and considered an unconventional form of natural gas, refers

to a kind of hydrocarbon gas (predominantly methane) found trapped within coal beds, mainly adsorbed to the surface of coal

matrix particles, and partly dispersed in the porosity of coal or dissolved in the coalbed water.

Shale Gas

Shale gas specifically refers to an unconventional form of natural gas found trapped within shale formations.

Tight Gas

Tight gas is an unconventional form of natural gas found in sandstone formations with permeability less than 0.1 millidarcy.

Deepwater Semi-Submersible Drilling Platform

Deepwater semi-submersible drilling platform refers to a semi-submersible drilling platform that can operate in deep waters.

Semi-submersible drilling platform, also known as column-stabilised drilling platform, is a kind of mobile drilling platform with

small waterplane area and a large part of the floating structure submerged under water.

FPSO

FPSO (Floating Production Storage & Offloading), namely floating production storage & offloading device, which is an oil & gas

production device combined with production processing, storage output and livelihood & power supply. Its complex in system

and price are far higher than that in oil tanker with same shipping tons. As an important part for marine oil & gas development

system, FPSO device constitutes a complete set of production system generally with underwater oil production devices, and

becomes a high-tech product among offshore engineering vessels at present.
