An International Petroleum Group

A far-reaching scope

Sonatrach is the Algerian oil and gas company. According to the Petroleum Intelligence Weekly, it is ranked as the twelveth company in the world.
It is the first oil company in the Mediterranean, the fourth world largest exporter of natural gas and the second one for LPG.

A leading role

Upon its creation in december 1963, Sonatrach role was, essentially, to contribute in the national development of Algeria. It was mostly targeted to generate external payment means, but also to meet the existing and future hydrocarbons requirements of Algeria.

An impressive growth

For purposes of maximizing the long term value of the Algerian hydrocarbons resources, Sonatrach undertook a tremendous development of activities.
Production has been multiplied by four since 1970 and is expected to be twice as much by 2007.

Significant assets
- A highly qualified human potential.
- A very competitive and attractive law on hydrocarbons.
- An important reserve base.
- Sedimentary basins with a high potential and still largely under-explored.
- An expertise of thirty years operations in field exploitation and development.
- A great experience in gas industry.
- A privileged geo-economic situation, neighbouring the important European Union market and open to the remainder of the world.
- A most positive partnership track record.

A Growing Petroleum Group

With the new bylaws adopted in 1998, the role of Sonatrach will focus on thefollowing strategic actions:

. prospection, exploration and exploitation ;
. development, operating and management of transportation, storing and loading facilities ;
. transformation and refining ;
. marketing ;
. natural gas liquefaction, processing and valorization of gaseous hydrocarbons ;
. setting up of any form of joint-venture activities inside and outside Algeria, with Algerian or foreign companies ;
. a constant supply of hydrocarbons for domestic purposes ;
. the search for the promotion and the valorization of any other energy form and source ;
. the development of any activity being directly or indirectly connected with the hydrocarbons industry.

The strategic objectives of Sonatrach are based upon
- A continuous control over its core business.
- The reinforcement of its management and technological capacities.
- A real partnership and international expansion.
- The diversification of its activities portfolio.

A New Organization

Sonatrach is, today, the driving engine for the Algerian economic development. It is not only the national company generating revenues for the state, but it is also, and mostly, a performing industrial and services pole. Early 1998, Sonatrach Group was commissioned by the Energy National Council to cover a whole range of new activities such as refining, petrochemicals, distribution and oil services. As a consequence of that, Sonatrach, today, holds the entirety (100 %) of the capital in the distribution, refining and petrochemicals companies: NAFTAL, NAFTEC and ENIP. It also has a 51 % stake in the capital of the oil services companies: ENGTP, ENAFOR, ENAGEO, ENTP and ENSP.

Promising Perspectives

Sonatrach's medium-term commitment is to reach significant success in downstream activities and mainly in the petrochemical industries using natural gas and LPG as feedstock. Sonatrach extensive experience over the entire oil industry chain made possible, and at the same time necessary, the expansion of its activities towards international investment schemes and export of services, both upstream (prospection, exploration) and downstream where real joint-venture opportunities exist.
The company's commitment to establish a real process of modernisation and expansion, translates the ambition of Sonatrach to adapt to the world oil industry changes and to reinforce its dynamic position for the next century.

Partnership: A Strategic Choice



This opening up of the oil upstream to international partnership is already translating today into remarkable results: in less than one decade, the Petroleum Algeria which was absent from oil companies exploration objectives has become the country where most hydrocarbons discoveries are made in the world. The Berkine Basin, a new petroleum province with a concentration of giant fields, is a striking demonstration of partnership contribution and its multiple benefits.

On the other hand, the incentive of competitively has been beneficial to Algerian oils services companies and some of them have already undertaken remarkable technological leveling and significant mutations in their managerial practices.

These companies, which are now within Sonatrach Group, have shown their capacity to capture their share of the market in a competitive environment. Indeed, the 1990 decade was that of an intensive exercise of partnering practice with, as a prime objective, to change partners "mind set" about the Algerian upstream.

In parallel, this approach required an internal adaptation inside the company; in order to have a real corporation culture with managers and technicians becoming familiar with the partnering perception within the company.

(Speech of the chairman and chief executive officer
of Sonatrach at the opening session
of the 4th JST. April 16th 2000).

About 50 contracts have been signed since 1987.

Whereas this number is appreciable, it is, yet, below owe expectations, when put into perspective with owe competitive achievements.

To date, some twenty oil companies are operating in Algeria:

This partnership contribution has been significant:

- more than 2.5 billion dollars invested inn exploration ;
- 56 discoveries, some of them being giant fields ;
- a total hydrocarbon volume in place of about 10 billion barrels oil equivalent.

These results largely contributed in the reserves of Algerian reserves, which have reached a level above the one-recorded carry 70's, that is to say, catching up with more than 30 years of conception and export.

In addition, these partnership activities have provided a workload to Algerian companies and namely those of the petroleum sector, and have stimulated competitively and better oil serves at a lower cost. These have also contributed in the technology and know how transfer.

The main joint ventures are:

- The joint-venture with Air Liquid and Air Products for the extraction of helium in Arzew ;
- The one with Respell for the production of PEHD in Skikda ;
- The latest one with Bast for the production of propylene in Spain, and a captive market for some of own propane exports.

Oil services and activities connected with engineering, construction and maintenance are also privileged segments of partnership between the client and the supplier. The interest of Sonatrach, which is transfer of technology and know how, reduction of costs and a better service, converges with the interest of the partner to access a large growing market.

Twelve joint ventures are already quite active towards this objective, and other Algerian companies as partners.

in the JST4; April 16th 2000).

A partner will be welcome and sought for



The partnering experience we have had over the last 10 years, even if beneficial for us and for our partners, did have some weaknesses mostly due to difficulties of raising the huge resources required by the significant exploration successful operations as well as to the ambiguity of the dual situation of a company having also to act as a public entity.

The redefinition of the State spheres of responsibility and the clarification of the means of involvement, both as a public entity and a shareholder, are, in my view, the most fundamental and the most promising perspectives for the hydrocarbons industry in Algeria.

A perspective and a context which relieve Sonatrach from constraints while, at the same time, require deep changes within Sonatrach which has to adapt its strategies, its functioning ways and its partnering practices to the current standards of its businesses and the evolution of its environment.

That a partnership quality step which does coincide with the objective to turn Sonatrach into a partner no longer required to carry out, on behalf of the State, functions which have so far given it a status of a partner bound to go through, but will rather enable it to become a partner which will be welcome and sought for. In other words, a partner chose for its comparative advantages.

I will point out those connected with its good knowledge of the opportunities existing in the Algerian Hydrocarbons industry and its success factors. Efficiency and performance are greater when they are induced by operating practices exclusively targeted towards the requirements of our care businesses.

Our goal is to break with the image of control and follow up in favor of a reality of being a partner, on equal footing a partner, which participates, is active and contributes to solutions.

Creating wealth will be the driver of our partnering approach, and the prime objective of our activities. Competition criteria, commercial and transparency rules will be our references in our relationships and dealings.

The upstream and, more and more, the downstream are, clearly, areas of opportunities for this evolution of partnering perceptions. The numerous and tangible business possibilities will, not only generate more partnership under the schemes practiced so far, but also under more integrated and more advanced cooperation forms.

Such an integrated partnering form entails cross interest stakes, which is, in fact, a synthesis between objectives of access to reserves for international companies and our own outsourcing goals.

That is already the start for alliances, a form of strategic cooperation motivated by convergence, whether it is around a geographical zone, a segment of activities which would justify a durable cooperation centered around joint coordinated actions and fully benefiting by the capacities and core businesses of the joint partners.

Obviously, it is a form of cooperation, which is more appropriate and more adapted to broader business opportunities as well as to the increasing competition generated by the global economy.

(Speech of the chairman and chief executive officer
of Sonatrach at the opening session
of the 4th JST. April 16th 2000).

Alignment of Interest


Activities of hydrocarbons processing and particularly petrochemical are less developed and offer all the ingredients for diversified partnership schemes. They can be centered around a project, generalized to a business unit, geared towards targeted markets, specific to the development of a new project or new process, located in Algeria or in "captive markets".

It is an industry with an impressive and diversified project portfolio.

The range goes from the giant project with large capacity, capital intensive and requiring a high level technology such as the ethylene stream cracking, to units transforming petrochemical products into consumption goods and which are less demanding, more attractive in terms of usage's, less risky and generator of a satisfactory profitability.

The concept of partnership is not, indeed, limited to a cooperation restricted to common projects located in the host country.

As the springboard for the development of national economic activities, partnering has to be extended to international activities.

Outsourcing production and marketing of goods and services is a must for Algerian companies and a challenge for a performing and competitive economy capable of delivering wealth.

We will base the outsourcing of our activities on alignment of interest, complementarily of attributes and sharing of resources with our international partners, but also, on synergies with our national partners.

As an illustration, the evolutions showing up in the European gas markets urge us to adjust our practices and, through our presence and our involvement in these markets, capture new segments and stabilize our outlets.

The first objective requires business participation on said markets, in association with our current partners but also with new player, emerging with the market liberalization.

The second objective will be reached through participation in major projects with gas as a feedstock, such as power generation stations. For this purpose, combining Sonatrach and Sonelgaz specific assets, in favor of this gas-electricity convergence, enables us to invest jointly and in cooperation with other partners, in Algeria and outside our borders.

The L.P.G. Chain

· The L.P.G. chain lies over nearly 1.500 km, from the Alrar fields, south-east of Algeria to the northern separation plants in Arzew.

The development of this chain is a major strategic objective aimed at valorizing the country's gas resources.

In addition to the export of 60 billion cm of natural gas, Sonatrach development plan, over the decade, provides for the doubling of the LPG supplies from the fields, which, by the end of 1999, will go from 5.3 million tons to 9 million tons.

· This plan is set around 4 main axes:

1. The development of new gas fields located south-east of Hassi-R'Mel for the recovery of gas, condensate and LPG

2. The recovery of LPG and condensate from operating fields.

3. The construction of an LPG pipeline (LR1) to dispose of the produced LPG

4. The extension of the separation capacities in GP1Z and GP2Z complexes of Arzew.

The production of LPG extracted from the fields, subsequently to the gas separation and crude oil processing, accounts for nearly 80 % of the domestic supply, the remainder (20 %) being from Arzew, Algiers and liquefaction complexes GL2Z (Arzew) and GL1K (Skikda).

· Up Stream

· The development plan of the chain provides for the installation of eleven units for LPG extraction:

- Five (5) are completed and operational. Hassi-R'Mel field is the most important one with a production of 3 MT; it accounts for more than 65 % of this production.

The other projects are Oued-Noumer, Alrar-West, Hassi-Messaoud, Hamra (in partnership with Total) and Tin-Fouyé-Tabankort (in partnership with Total and Respol).

- Two (2) are under construction: Hassi-R'Mel-South and Rhourde-Nouss phase B.

- The four (4) remaining one are under maturation: In-Amenas, Ohanet, Gassi-Touil, Rhourde-el-Baguel.

· Main extraction processes

The liquefied petroleum gas (LPG) which is mainly made up of propane and butane, derives essentially from the processing of natural gas and gas associated with crude oil.

Its extraction is made out of butane and propane condensation through compression cycles, expansion and cooling of gas.

The expansion, which provides the main part of the product, is achieved through a Joule Thomson valve or a turbine-expander while cooling is generally carried-out through a propane loop and the recovery of frigories available in the unit.

· Evolution of the contractual capacities
FieldsLPG Production capacities (tons/day)
Hassi-R'Mel 10.263
Oued-Noumes 1.200
Rhourde-Nouss 6.360
Hamra 1.410
Tin-Fouyé-Tabankort 2.100
Ohanet 1.250
Alrar-East 2.212
Alrar-West 770

· Transportation

· LPG extracted from fields has being transported through the Alrar-Hassi-R'Mel LPG (LR1) oil pipeline since May 1996.

This 988 km pipeline, with a telescopic shape, gathers all the LPG produced in south-eastern fields in order to forward them to the main gathering center of Hassi-R'Mel from where they are removed towards the separation complexes of Arzew through the 24 inches pipeline (the LZ1) which has been on stream since 1984. The LZ1 pipeline is 504 km long and has a transportation capacity of 6M tons/year, in the first stage. A second station planned for 2001 will raise its capacity to 9 MT/year.

· Down stream

· In order to be inline with the development of the fields production, the capacities of the GP1Z (Jumbo LPG) and GP2Z separation complexes installed in Arzew, to the North, have been significantly expanded during the last decade.

· GP1Z Complex

This gas complex, GPZ1, which was set up at the beginning of the eighties under the mascot sign of Jumbo, the African elephant, well deserves its qualification as a giant.
Following the renovate of some bottlenecks and as of 1996, the development plan undertaken in 1994, has already resulted in an increase of the production capacity of the LPG project, stage II, lead to two new trains which came on stream in July 1998.

Currently, the GPZ1 Complex counts six trains of a capacity of 1.2 million tons/year, or a total annual capacity of 7.2 million tons/year.

· GP2Z Complex

· The upgrading of the existing trains, which started in 1993, has allowed the doubling of the separation capacity of the GP2Z Complex. This one has gone up from 0.6 MT in 1993 to 1.2MT at the end of the year 1996. This capacity will go up to 1.8 MT per year in 1999.

· Owing to an effective marketing strategy. Sonatrach is attempting to promote LPG use on new markets. In this respect, discussions have already taken place with prospective customers to whom the LPG solution seems too be very appealing for the Mediterranean region: Baleares, Sardinia, Cyprus, Turkey…

The LPG scopes of application knew a notable development these two last years. Besides the urban domestic market and the petrochemical branch, key LPG consumers so far, a fully expanding activity is gaining grounds: automobile fueling. LPG-fuel, sustained by an incentive tax policy, and pushed to the front by green pressure groups, is likely to witness an upward trend within the energy balance of well-off nations. The key asset of LPG remains the drastic reduction of noxious emissions, considered as the prime concern of the moment. The use of Propane might definitely reduce the sulfur dioxide emissions, cut to 60 % those of carbon dioxide and to 50 % the nitrogen oxides. Power generation is another bright prospect for LPG use.

Sonatrach started design studies on the possibility to use LPG in power supply sector, and the results showed that a relatively important part of its new production will be taken over by said sector. This is particularly true when isolated or secluded regions or areas (islands, niches…) are concerned, where there is no opportunity to supplying them by gas pipeline or LNG, LPG, altogether with the combined cycles technology, adding to obvious ecological considerations offers huge advantages.

In this respect, discussions have already taken place with prospective customers to whom the LPG solution seems to be very appealing or the Mediterranean region Baleares, Sardinia, Cyprus, Turkey… In order to meet an ongoing growing demand, and to double the LPG export-capacity as early as the next millenary (2001), Sonatrach committed a purchase schedule to endow itself with a modern fleet aiming at answering adequately its customer's requirements. Through its London affiliate "Sonatrach Petroleum Corporation" (SPC), specialized in despondent ship handling, Sonatrach overtakes an 80 % fleet exploitation meant to answers its LPG shipping requirements. Besides the two ships it may avail as an owner (the "Djemila" and the "Nedjma"), SPVC London is also acting as a time ship handler.

It also intends to purchase two ships for LPG transport, "Reggane" and "Djanet" which are being constructed and will be delivered respectively by the end of 1999 and during the year 2000.

The availability of an important fleet to help export LPG a shipment enables a greater versatility as compared with the production facilities, and a safer supply delivery.

This market dynamic prolongs itself downstream in new activities. As early as 1997, a "letter of intent" was signed by Sonatrach and the German Company BASF AKTIENGESELSCHAFT, for the construction of a dehydrogenation unit of 450.000 T/year capacity of propane, and 350.000 T/year of propylene. Being Sonatrach's first international participation in petrochemical downstream activity, this plant will be realized in Tarragona (Spain) on BASF affiliate's site.

Sonatrach, departing from its Bethioua's production facilities, will be the sole LPG supplier (Propane-content). For Sonatrach, world second LPG supplier, this long-term cooperation project means opening new prospects to Algerian LPG's, in terms of outlets. At the same time, Sonatrach and BASF are forging a way ahead for a further cooperation in downstream activities in Algeria. As it has already clerically reasserted it in its development scheme, Sonatrach is very much in favor of joining an associate, too invest in a condensate distillation plant and an ethane vapocracker in Algeria.
