Start here Work in pairs Talk about accidental discoveries or inventions in science or technology which you have heard about Example: 1 Alexander Fleming was growing some bacteria in his lab when some penicillium fungus fell on the bacteria and killed them That is how he accidentally discovered antibiotics Task Work in pairs Match the notes 1–6 with the accidental discoveries X-ray vulcanised rubber safety glass inkjet printer co-ordinate geometry antibiotics Alexander Fleming – grows bacteria in lab – penicillium fungus falls on bacteria – fungus kills them Charles Goodyear – works with raw rubber powder containing sulphur – brushes powder off hands – powder falls onto hot stove – forms tough elastic substance Rene Descartes – watches insect flying around room – realises he can specify insect’s position in 3D space as – distance from two walls and ceiling Wilhelm Roentgen – projects light from cathode ray generator onto wall – sees outline of bones of own hand on wall Ichiro Endo, engineer – works with a hot iron and a syringe full of ink – touches neck of syringe with iron – forces ink out Edouard Benedictus – puts away glass flask – flask contains liquid plastic – drops flask on floor – flask doesn’t break – thin plastic film holds pieces together Describe the accidental discoveries outlined in the notes in 2 Use the past continuous and the past simple tenses where appropriate Language page 101 Example: 1 – see the example in 1 Writing Write about the discoveries and inventions you talked about in 1, using the past simple and continuous Follow the example in 1 Scanning Practise your speed reading Look for the information you need on the SPEED SEARCH pages (116–117) Try to be first to complete this text We don’t know if Archimedes really stepped into his bath and shouted ‘Eureka!’ (‘I’ve discovered it!’) when the water level (1) But we do know that he discovered that a body immersed in fluid experiences a (2) force equal to the weight of the liquid displaced We also know that Archimedes invented the (3) and the (4) Innovations M01_TECH_SB_04_9552_U01.indd 28/01/2011 16:26 Listening 02 Listen to this talk and choose the picture that illustrates what Jaap (Will’s colleague) was looking at when he had his eureka moment Listen again and answer these questions Speaking In the question and answer session after his talk, Will gives these answers Write down the questions that were asked Then practise the questions and answers in pairs Language page 102 What is Will’s (the speaker’s) job title at his petroleum company in Brunei? What problem has the speaker been trying to solve for the last few years? What was happening when Jaap suddenly had his eureka moment? What was the name of the type of drill that Jaap and his team invented as a result? How does this new drill solve Will’s problem? Language Well, I would say that the main reason for using snake well technology is mainly economic Snake wells allow us to get more oil out of a single field Yes, it does The technology has a very big environmental benefit, because snake wells mean that you can build fewer oil platforms and do less drilling Yes, we are We’re using it right now, at this very moment We have a number of snake wells in operation off the coast of Brunei Well, most of the oil in the Brunei field is between 2,000 and 4,000 metres below the seabed, I think We’ve been drilling snake wells off the Brunei coast since 2005 Well, our company first started exploring the Brunei field a long time ago I believe the first survey was in the 1980s Yes, we have In addition to the snake well, we’ve been developing a system of sensors that transmit data from the drill bit back to computers on the surface Well, I don’t know exactly what my next project is going to be! Maybe I’ll drill a snake well off the coast of Nigeria Present perfect continuous How long have Our company  Speaking you has been using snake wells? them  since 2005 Work in pairs Take turns to act the roles of a reporter and an oil company representative When you are the reporter, use the present perfect continuous in your first question about each project, and then follow up with different types of questions Student A: Turn to page 115 Student B: Turn to page 113 Oil sands, Canada: how long? surface / underground mining? area project covers? kind of oil extracted? extracted oil converted into …? expected length of project? Drilling for gas, Russia: how long? based where in Russia? onshore / offshore? gas converted into ? meaning of ‘LNG’? future exports to ? expected production (tonnes)? M01_TECH_SB_04_9552_U01.indd Innovations 28/01/2011 16:26 Smart wells Start here Work in pairs Discuss these questions about the illustration below Make notes What are the advantages of this method of oil extraction compared with vertical wells? How do you think computers are used in this method? ‘Snake’ well system below seabed ‘Snake’ wells connect pockets of oil that stretch for up to miles under the seabed seabed gas oil Valves and seals are located in the oil pockets so they can be isolated if they start to pump too much gas or water Reading OIL FIELDS 10 15 If an oil company discovers a large single reservoir of oil and gas, the solution is simple: drill a vertical well down to the reservoir and bring up the oil But what can be done when an oilfield consists of hundreds or even thousands of small, isolated pockets of oil? It would be too expensive to drill hundreds of vertical wells to reach all the small pockets The innovative solution to this problem is the ‘snake well’ Unlike the conventional vertical well, this is a horizontal well that weaves laterally back and forth across a number of oil-containing zones Guided by smart technology, a single snake well can gas oil water Read this article and check the notes you made in 1 SMART oil 20 25 30 35 access multiple pockets of oil and achieve output equivalent to several individual wells, which has the dual advantage of reducing cost and ensuring that no oil is overlooked A snake well uses steerable drills that can be positioned with great accuracy Special imaging software generates detailed computer models of underground geology and reservoirs This enables drills to hit a target far underground that is less than two metres across Located 90 km off the coast of Brunei, the Champion West oilfield is Shell’s flagship project using Smart Fields technology For 30 years, Champion West lay dormant, its rich oil reserves locked 2,000 to 4,000 m beneath the seabed in a complex web of small reservoirs (see illustration above) In the past, these small pockets of oil were too expensive to develop But now Champion West has been changed into one of the world’s most advanced oil and gas fields by means of Smart 40 45 50 55 60 Fields  technology and new drilling techniques Buried deep beneath Champion West’s seabed, sensors relay digital information about temperature, pressure and other factors to control centres on land by means of a network of fibre-optic cables This enables continuous monitoring of production, and engineers can make speedy decisions on how best to extract the maximum amount of oil, monitor its movement within the reservoir and instantly notice production problems, such as blockages They can take action to solve problems, for example by the remote electronic activation of hydraulic well valves If gas or water threatens to break into the well, for example, the valve for that section can be closed down using a remote control Swellable seals are used to isolate the zones from one another, and prevent fluid from one zone from flowing into another adjacent zone Innovations M01_TECH_SB_04_9552_U01.indd 28/01/2011 16:26 Answer these questions about the article What are the two main economic reasons for drilling a snake well? How accurate is the drill of a snake well when it is guided remotely? For how long was the Champion West oilfield left unused following the discovery of oil there? Why was it left unused? How is data about conditions inside the snake well transmitted to the surface? How do engineers stop the oil in the well being contaminated with water or gas?
