Urucu Oil Province

Urucu Oil Province is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Urucu Oil Province rather than just read about it. In short: The Urucu Oil Province (Portuguese: Provincia Petroleira de Urucu) is a Brazilian oil and natural gas field located in the municipality of Coari, in the interior of the state of Amazonas. It is the largest proven onshore oil and natural gas reserve in Brazil, according to Petrobras.

Key takeaways

Urucu Oil Province belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Urucu Oil Province to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Urucu Oil Province from memory before moving on to harder problems.

Reference excerpt

The Urucu Oil Province (Portuguese: Provincia Petroleira de Urucu) is a Brazilian oil and natural gas field located in the municipality of Coari, in the interior of the state of Amazonas. It is the largest proven onshore oil and natural gas reserve in Brazil, according to Petrobras.

History The Urucu field was discovered on October 12, 1986, by Petrobras, although searches for oil in the Amazon date back to 1917. It is the first commercially viable reserve discovered in the Amazon region.

Extraction and logistics The Amazon region, and in particular the Solimões Basin, is the largest onshore natural gas basin and the fourth largest oil basin in Brazil in terms of reserves and production. The state of Amazonas, which includes the Solimões Basin and the Amazonas Basin, concentrates 80% of Brazil's proven onshore gas reserves and 12% of proven onshore oil reserves. Today, the Solimões Basin produces an average of 40,000 barrels per day of oil and 11 million cubic meters per day of gas. The oil is of excellent quality, very light. The gas is quite wet, that is, it contains a high proportion of condensate and liquified petroleum gas (LPG). Despite the logistical difficulty in the Amazon, the cost of extracting oil and natural gas from Urucu is among the lowest in Brazil. According to Petrobras, the oil province is profitable and important for the development of the local economy. Urucu has a set of pipelines that allow the production to flow. Since 2009, the Urucu-Manaus pipeline has been operating, connecting the oil province to the capital of Amazonas, with a total length of 663 kilometers. The pipeline is capable of transporting up to 5.5 million cubic meters per day of natural gas from Urucu to the Amazonas capital. In addition, the field accounts for the daily production of approximately 1.2 tons of LPG, a volume capable of supplying seven states in the North region and others in the Northeast. In the beginning, before the existence of the gas pipeline, it took more than a week to drain the production by small ferries down the Urucu River to the city of Coari, on the banks of the Solimões River and from there, in larger ferries, to the Manaus Refinery (Refinaria de Manaus - Reman).

Impacts on the local economy The municipality of Coari had the second highest GDP in Amazonas in 2018, with R$2 billion and a 2% share. In 2017 Coari was in fourth position among the state's municipalities, it moved to second position in 2018, where its GDP increase was occasioned by the strong boost from the extractive industry.

Worked examples

Example 1 — a first encounter with Urucu Oil Province

Start with the simplest possible case. Write down what Urucu Oil Province claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Urucu Oil Province before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Urucu Oil Province ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Urucu Oil Province

In research: Urucu Oil Province appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Urucu Oil Province in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Urucu Oil Province is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil fuels in Brazil, Petroleum, Petroleum by continent, so understanding it makes those chapters shorter.
In everyday life: Look for Urucu Oil Province outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
