NATURAL GAS - ITS ROLE IN THE ECONOMIC DEVELOPMENT OF Trinidad and Tobago
Presented by Frank Look Kin,
Vice President
Business Development, The
Natural GasCompany of T&T LTD at the 1995 Annual Dinner Dance.
INTRODUCTION
Thank you Mr. Chairman, distinguished guests, ladies and gentlemen. It is an honor to be invited to address this distinguished gathering of Earth Scientists and Professionals of the Geological Society of Trinidad and Tobago. Tonight I propose to talk about the natural gas industry of Trinidad and Tobago. The gas based sector -of the energy industries in Trinidad has been on a sustained growth path since the mid to late '70s and this is expected to continue at almost the same pace for the next five (5) years and more. I welcome this opportunity in the 21st year of The National Gas Company of Trinidad and Tobago to provide you with some insight into the strategic growth and development of the gas business here in Trinidad and Tobago and the tremendous opportunities that arise therefrom.
HISTORICAL ANTECEDENTS
The gas industry is as old as the oil industry since they are inextricably linked by mother nature. The production of natural gas was associated with crude oil, and gas was used in oil company operations as fuel and for gas-lifting in oil production. Its commercial use outside of the oil fields and refineries did not begin until the start-up of the first anhydrous ammonia plant by Federation Chemicals Limited, a subsidiary of W R Grace in 1959. That was the first gas based petrochemical plant in Trinidad and Tobago and it was based on the development of Penal gas condensate field in South Trinidad. The use of natural gas expanded with its use as the primary fuel in the generation of electricity for public supply in 1964.
The discovery of significant gas reserves by Amoco Trinidad Oil Company in its offshore East Coast licensed areas in 1968 with the drilling of OPR - 2, provided one of the prime catalysts for the rapid expansion of the gas industry in the decade of the 1970's. This discovery was followed by an expansion of the natural gas resource base with the additions of gas discoveries in the South East Galeota, East Mayaro, East Manzanilla fields by Amoco, the Pelican, Kiskadee, Ibis and Oil bird fields by the South East Coast Consortium, the Dolphin field by Texaco/Tenneco and the KK-4, Chaconia and Poinsettia field in the North Coast Marine area by the DATO Consortium and by Petrotrin.
In August 1975, this country's government established the National Gas Company of Trinidad and Tobago Limited (NGC) to purchase, sell and distribute natural gas in Trinidad and Tobago. With the initial asset base of the T & TEC's 16" gas pipeline from Penal to Port of Spain, NGC entered into the gas transmission business. Three (3) years later, the government funded the construction of a twenty-four inch (24") offshore and land pipeline system to transport gas from the offshore gas field to consumers on the west coast of the island. The capacity of this line was 400 mmcf from Amoco Teak gas field to Point Lisas. In 1983/1984, a 30" submarine line was laid from the Amoco Cassia field to Abyssinia, Guayaguayare and a 30" cross country pipeline was laid to Point Lisas but this time via Rio Claro and more northerly route through the center of the island. This 2nd line has a design capacity of 600mmcfd.
NATURAL GAS RESERVES AND PRODUCTION
It is significant to note that it was the high oil prices in the mid-1 970s which stimulated an intensification of the oil exploration effort in Trinidad and Tobago by various licensees and this resulted in the discovery of significant gas reserves off the east and north coasts of Trinidad. These discoveries were not a result of specific exploration for gas and this led to a search for gas based industries to utilize and monetize this valuable natural resource.
On the basis of the evaluation by independent petroleum consultants supplemented by-updates from the Ministry of Energy and Energy Resource, the nonassociated natural gas reserves in Trinidad and Tobago as at January 01, 1995 were estimated at some 18.8 trillion cubic feet. A breakdown of this figure gives 10.1 trillion cubic feet as proved reserves; 6.0 trillion cubic feet as discounted probable reserves and 2.7 trillion cubic feet of discounted possible reserves.
The bulk of these gas reserves (some 75%) is located in the east coast marine area. The remainder is primarily in the north coast marine area which is still undeveloped. The current proven reserves to production ratio of is in order of forty five (45) years and this could well extend beyond 80 years with the inclusion of the discounted probable and possible reserves. However, this picture changes when we include possible gas demand that are being pursued.
Amoco Trinidad Oil Company has been the main supplier of natural gas to the NGC since 1975 with production derived from its Teak, Cassia, Flamboyant and Immortelle fields. In fact, Amoco was the only supplier until 1982, when NGC invested in two (2) offshore gas compression platforms as a conservation project. This project entailed the collection and compression of associated low pressure gas that was being flared from Amoco's Teak and Poui oil fields. These facilities are presently producing some 110 million cubic feet of gas per day while today Amoco supplies the NGC some 344 mmcfd.
In 1988, a second supply source the Pelican field - was developed by Trintomar in the South East Coast Consortium (SECC) licensed area. This field's production peaked at 130 million cubic feet per day in early 1991 and experienced a precipitous decline afterwards. The third supplier - Enron Gas and Oil Limited with a sub-license for the SECC licensed area excluding the Pelican field - began gas production from the Kiskadee field in November 1993. Today Enron supplies NGC with 22% of its requirements at 130 mmcfd.
The NGC has contracted additional gas supplies from the Dolphin field on the east coast from British Gas Texaco. This production is expected in the first quarter of 1996. At the end of the third quarter in 1995 some 588 million cubic feet of gas were supplied. Distribution among suppliers was as follows:
344 mmcfd from Amoco Trinidad Oil Company representing 59% of total supply;
130 mmcfd from Enron Gas & Oil Trinidad Limited representing 22% of total supply;
110 mmcfd from NGC representing 19% of total supply;
8 mmcfd from Trintomar representing 1.9% of total supply; and
2 mmcfd from Coastline International Ltd., a small land based producer in the Tabaquite field.
The multiplicity of suppliers and supply sources significantly enhance the security and reliability of the gas supply and supports the further development of the gas market in Trinidad and Tobago.
MARKET DEVELOPMENT 1975 TO 1994 The expansion of natural gas market and gas use in Trinidad and Tobago has accelerated tremendously since the mid 1970s. This was a direct result of the deliberate strategy of resource-based industrialization, the main goal of which was the monetisation of the substantial reserves of natural gas which had become available.
Funded largely by the government with fiscal surpluses earned in the oil boom, this strategy resulted in the establishment of several major gas-based petrochemical plants on the Point Lisas Industrial Estate: four ammonia plants; one urea plant; two methanol facilities; a direct reduced iron (DRI) and steel plant; an iron carbide plant; a natural gas recovery plant; and an electric power plant.
All plants were either wholly or majority owned by the government which invested one point eight billion US dollars (US$1.8 billion) in these industries over the period 1975 to 1990.
In its role as owner of a gas transmission system and transporter of natural gas, the NGC has had a good record of reliable service to customers. The present main gas transmission network consists of two major sub-sea and subterranean pipelines of 24" and 30" in diameter. The pipeline system has a combined throughput capacity of 750 million cubic feet per day and transports gas at an inlet pressure of 900 psi from the east coast fields to the natural gas liquid recovery plant in Point Lisas and then on to our various customers.
The gas is of an excellent quality with a high methane content greater that 96%, less than 5 ppm sulphur and about 0.5% carbon dioxide' It is an excellent feedstock for reforming into hydrogen and carbon monoxide, prime building blocks for manufacture of ammonia and methanol and an excellent fuel for heating in industrial, commercial and domestic applications.
Natural gas sales by the NGC increased from the level of 150 mmcfd in 1978 to over 570 mmcfd in 1994. This remarkable growth represents an average of 9% compound annual growth rate in gas use. The petrochemical sector was the principal driver of this growth performance with gas sales to this sector increasing by 11 % per year due to the phased investment in new petrochemical plants. Sales to the heavy industrial sector increased by 5.1%, power generation by 6.9% and the light industrial and commercial sector by 6.3%.
The natural gas industry has now emerged as a leading economic sector in Trinidad and Tobago. Petrochemicals alone accounted for 17% of total export earnings in 1993, compared with a share of 5.2% ten years earlier, and contributed over 10% of real GDP (gross domestic product). The rate of real growth in this sector (which is about 8.8% per year) has mitigated the rate of decline in the overall economy between 1983 and 1994. The share of natural gas in total industrial energy demand in Trinidad and Tobago is in excess of 80%.
Five (5) significant features
of the evolution of the natural gas market should be noted:
1) Most of the reserves
were discovered during the period of the oil boom when price provided an
adequate incentive for the exploration investment;
2) Market development involved
significant levels of capital investment by the government on both plant
and infrastructure;
3) The development of the
industry was-essentially demand-driven, that is, investment decisions in
gasbased plants provided the basis for NGC to seek new suppliers. Stated
in a different way, supply responded to demand.
4) The supply of gas was
dominated by one producer with well head prices determined on a production
cost basis and set with fixed escalators; and
5) In 1992, the government
identified the natural gas industry as the engine of growth in the economy
and mandated the National Gas Company to be the prime mover in gas-based
development.
INDUSTRY OUTLOOK
The next five (5) years are likely to witness continued growth in all sectors of the natural gas business. We expect to see an increase in gas consumption from the current 600 mmcfd to over 1,300 mmcfd by the turn of the century - inclusive of Liquefied Natural Gas (LNG).
In the petrochemical sector, an eight to ten percent growth rate is expected. A third methanol plant is already in a pre-start up mode - ahead of schedule.
Last month, approval was granted by Hermes to provide insurance for the project financing of a 4th Methanol Plant under the sponsorship of Ferrostaal, Caribbean Methanol Company and the Government of Trinidad and Tobago. This 4th Plant will be build in Point Lisas adjacent to the 3rd Plant and is expected to be completed by 1998.
In addition, there is interest in the construction of a 5th plant with a capacity of 850,000 tonnes per year by Saturn Methanol Company using an alternate technology Lurgi Process. If both plants materialize, the total plant capacity for Methanol production in Trinidad and Tobago will be almost 3 million tonnes per year. This will be approximately 9% of total world capacity of Methanol. Today, Trinidad and Tobago provides 10% of world Methanol trade and by 1998, it is projected to be up to 20% of the trade.
Recent developments in the former Soviet Union have heightened concerns about security of supply of ammonia from that source and will no doubt strengthen interest in establishing new ammonia capacity in stable locations like Trinidad and Tobago. Farmland/Misschem have signaled its intent to establish an 800,000 tonne Ammonia facility in Trinidad and Tobago. This will bring the production capacity to over 3 million tonnes by 1998. The development strategy for this sector will focus on downstream petrochemical expansion aimed at increasing value added from natural gas. In the future, it is anticipated that some 25,000 barrels of ethane will be extracted for use as feedstock for downstream industry expansion.
In the heavy industrial sector, Trinidad and Tobago is emerging as a major centre for iron and steel production in the region. At present, the iron and steel plant produces 900,000 tonnes of direct reduced iron (DRI), and up to 700,000 tonnes of billets and 600,000 tonnes of wire rods on an annual basis. In 1994, the world's first commercial iron carbide plant owned by Nucor Corporation began production of iron carbide. Iron carbide and DRI are alternate feed stocks for scrap which is used in the manufacture of steel. The plant will produce some 320,000 tonnes annually and further expansion is likely. In addition there have been active discussion with another producer of scrap steel substitutes for the establishment of another gas based production facility. Discussions have been progressing with potential Aluminum producers for the establishment of a smelter in Trinidad since the electricity supply is gas based, the establishment-of such a plant will increase the demand for gas. In addition, the ongoing upgrade of the crude oil refinery will use additional volumes of natural gas as fuel, thus increasing gas use in the heavy industrial sector by 14% by 1998.
The strong correlation between power generation and economic growth was evident in this market during the period 1978 to 1983 when electricity consumption experienced a yearly growth of 7%. Over the next decade, excluding demand from the establishment of a smelter, natural gas consumption in this sector is forecast to grow by I or 2% per year. This will be due, in part, to increased efficiency in the conversion of natural gas to electricity and slower economic growth.
Growth in the light industrial and commercial sector over the last five (5) years has been stymied by limitations of the distribution network. A growth rate of 6 to 8% is anticipated in this sector, driven primarily by the promotion of new applications such as natural gas vehicles, natural gas cooling and co-generation and expansion of local gas distribution systems to new industrial estates. The potential gas cooling market is roughly estimated at three (3) mmcfd cubic feet per day. The NGC will be installing the first gas based air conditioning facility at Mt. Hope Hospital in 1996 and this will be followed by the Hilton Hotel which plans to convert to gas based air conditioning in 1996.
The industry outlook on liquefied natural gas (LNG) has been positive. For about two (2) years now, the NGC along with Amoco Trinidad Oil Company, British Gas and Cabot LNG Corporation has been working on the development of a liquefied natural gas export project. The project, involves the construction of an LNG plant with a single liquefaction process train capable of producing approximately 400 mmcfd of LNG for export by 1999. Deliveries of natural gas to the plant would be by Amoco from their east coast gas fields. The LNG will be marketed to Cabot LNG in the US northeastern states and to Enagas in Spain, Europe.
CONCLUSION
In concluding, I would like to point out that, on the one hand, while Trinidad and Tobago's oil production has been declining over time, on the other hand, natural gas production has been increasing. The country's natural gas reserves provide for it a significant role in the future of the natural gas world. Because of its small population and this high per capita gas reserves, it is in a potentially strong position as an exporter of natural gas products.
Prospects for growth in the natural gas business in Trinidad and Tobago are bright. The gas reserve base is large and the advent of several suppliers has enhanced security of supply. Wellhead prices are expected to remain competitive over the medium term while the flexible position of the NGC with respect to downstream pricing will enable present and future customers to maintain a competitive position in international markets.
The major challenge to members of this professional body - GSTT is to expand the gas reserve base in Trinidad and Tobago. While the present proven gas reserve base is adequate to support the existing and announced projects - LNG, Farmland and the 4th Methanol, it is imperative that further exploration and appraisal work must be continued to locate and prove up additional gas reserves to increase the gas reserve base. This natural gas reserve base together with our other advantages - proven ability to provide a secure gas supply, our skilled technocrats and a hospitable investment climate is necessary to increase investor and lender confidence in Trinidad and Tobago as a place to establish and continue gas based industrial development.
