BIRTH OF AN OIL FIELD 1949 SHELL OIL INDUSTRIAL FILM GEORGE PAL ANIMATION MD74772

[Music] [Applause] [Music] time intangible elusive time measured in years by the broad movement of planets measured in seconds by the inventions of man second tiny fragments of time marching th writing the pages of history as they pass in review 60 seconds every minute 3,600 seconds an hour 86,400 seconds every day and with the fleeting life of each and every war than 6000 gallons of oil are from the earth [Music] oil from the east oil from the West the north and the south oil from 30 states of the USA and from 50 countries of the world [Applause] oil coming from the earth in huge quantities to fill our increasing demand in the united states alone enough oil is produced daily in fact to float a giant ocean vessel and that's a job calling for a lot of manpower [Music] for example a famous football stadium seats over 100,000 persons yet 20 stadiums of this size can be filled to capacity by the number of persons steadily employed in the oil industry many men many jobs and all because less than a hundred years ago someone had an idea an idea that perhaps a man could find oil oil in huge quantities by boring a hole into the earth the idea of drilling specifically for oil was new but the principle employed was an old one almost three thousand years ago the ancient Chinese had developed a laborious method of drilling for salt the well drillers would jump on a springboard something like a diving board this would give slack to the rope stopping the tool to drop and pound into the earth out of this principle evolved with the early method of drilling for oil cable tool drilling in which a walking beam took over the job of lifting and dropping the drill tool to pound a hole now there are two common ways of forming a hole one way is to pound or punch out a hole as in cable tool drilling the other way is to bore or scrape out a hole and that's the idea behind modern rotary drilling using the refilling methods the search for oil has gone to almost unbelievable depth the famed Empire State Building towers more than a quarter of a mile above the streets of New York yet it's colossal height could be circu to the depths of one of the world deep oil wells and another such building and another and another and yet another until 15 Empire State building's have been sunk to approach the depths which have been reached by rotary drilling suppose we watch the big job of thinking a deep well by the rotary method the work begins with the erection of the dairy and the installation of the rig this equipment may have cost up to a quarter of a million dollars not to mention the fifty thousand it may have been spent just getting into the well location before this exploratory well is completed it may represent an investment of $1,000,000 and the chances of actually finding oil are about one in nine with the derrick and rig installed drilling operations get underway we are making hole a heavy steel rotary tables the drill string below ground a square hollow pipe called le works off the rotary table and fitting through a square hole is free to move up or down [Music] fitted to the Kelly is a length of drill pipe more and more of these 30-foot sections are added as the well goes deeper [Music] at the end of the drill pipe is a drill collar and below this the bit there are more than 50 different types of bits here a simple one is used to cut through the soft surface formation [Music] much scientifically treated mud plays a highly important role in drilling operation [Music] circulated by a battery of powerful pumps the mud is forced up into the swivel searching down through the hollow pipe of the drill string it Jets out around the bit to perform vital cooling and lubricating action returning up outside the drill pipe the mud seals the walls of the well this helps maintain pressure and prevents the walls from caving in in addition the mud carries up the drill cuttings from the bottom of the well providing important information about the strata which is being penetrated [Music] this is mud with a college education special chemicals and waiting materials are added from time to time to maintain the formula in precise balance [Music] as drilling progresses various types of underground formations are encountered [Music] now we're getting into hard stuff we'll have to exchange our bit for one design to penetrate this harder formation [Music] let's this means pulling the string a long job and one calling for precision teamwork between the members of the drilling crew and the ponderous equipment at their command [Music] section-by-section the huge pipe is hauled up carefully disjointed and stacked five men working as one handling tons of steel with a confidence born of long experience [Music] and here's the new bit designed for chewing through hard rock this and many others will be worn out before the drilling is completed [Music] [Applause] after the new bid is in place we'll have to recover and lower the string again [Music] we're drilling underway once more 3,000 4,000 5,000 feet down the going gets tougher slower hardrock and stop all trouble [Music] yes real trouble a broken drill string we have to quit drilling for the time being and go fishing an attempt must be made to bring up the twist-off or fish from its position thousands of feet below and here's the fishing tackle the socket designed to slip over the broken end of the drill string with dogs to clutch it it is lowered into the well on the drill string [Music] the operation may take several days sometimes the fish refuses to be caught even after every possible type of fishing tool has been used with the fishing not making much headway the engineers must decide whether to continue this costly operation or to abandon the well or to whip start the decision is quit start we are trying to go around the broken drill string by veering off from the straight hole yes now we're doing exactly that bi-directional drilling with a whip stock a beveled piece of steel shaped to deflect our bit over at the precise angle desired we are accomplishing the seemingly impossible feat of drilling a curved hole we have angled our well over to bypass the broken string and again the drilling is continued but now more cautiously than ever we're down past the 10,000 foot mark and nearing the spot that our scientists tell us should be productive formation rate of penetration had increased well we've got to get a sample of what we're hitting down there [Music] a special court taking Beryl is lowered into the drill string by means of a cable and windlass the core barrel held firmly within the drill collar works like grandma's cookie cutter it slices out the desired core sample which is retained within the barrel and hauled back to the surface on the cable a careful analysis proves our core to be essentially water-bearing despite minor oil State not good enough for production disappointing but maybe a little farther down another 300 400 feet and again the speed of penetration picks up this time we'll use electric logging to see what we're getting into [Music] this device consists of a group of electrical instruments which enable us to get an indication of the physical character and fluid content of the formation we have penetrated the reading looks favorable will chase the formation off [Music] a cementing outfit is called in the cement is mixed down the spot and pumped to a special connection at the top of the casing forced down with mud the cement Rises between the casing and the wall of the wells the cement and now we are ready to cut loose the heavy artillery a gun perforator is lowered into the well [Music] the device is fired heavy caliber bullets pierced the steel casing and cement to let in the oil now tubing has been running to the well and if she's going to produce it'll come through that tubing a Christmas tree has been added to control the expected flow oil or water is forced through the tubing to flush out the mud only about one out of nine exploratory wells is productive a few 10 seconds and we'll know about the one we've been working on for so many weeks it's now or never [Applause] [Music] we've honor in its the birth of an oil field [Music] [Applause] drilled and drilled on day and night respond drill man browses us on the the trails goes down and then goes round [Music] yet is the birth of an oil field one more victory and the ceaseless night and day job of searching drilling bringing up from the earth new supplies of petroleum to fill the increasing demands of modern living we drilled a well and found some oil now begins the many sided job of production getting the oil out of the ground and into the refineries to produce oil efficiently from this area additional well locations must be scientifically plotted and drilled in roads must be built equipment installed oil storage and treatment facilities erected pipelines lay a thousand and one casts performed by men of almost every sort of skill and training perhaps you'd like to meet one of these oil men a production engineer his job is conservation getting the last possible drop of oil from nature's reservoir and getting it efficiently pardon me mr. Benson mind if we ask you a question why certainly not but keep it simple with you well this should be easy for you when you're drilling a well what makes the oil flow to the surface well actually some new wells never do flow however when an oil well does flow on a tit it's usually because of gas pressure water pressure or a combination of both take a look at that model for instance that's a simple anticlinal structure an oil trap the oil bearing stratum is sandwiched between layers of impervious Rock which prevents the oil from escaping oil deposits you know occur in the pores of rock not in underground pools or lakes usually there is water found in connection with oil deposits since oil is lighter than water the two will be separated the oil occurring above the water where there is gas gas will always be found dissolved in the oil and in some cases additional gas will occur in a free state above the oil so much for studying the state now suppose we sink a well and tap the oil sands if the well flows it means that some form of natural energy is working for us otherwise we'd have to pump right right okay now when a flowing well the main source of energy that lifts the oil is in most cases expanding gas now the expanding gas well here let's take this siphon bottle our flowing well is similar to the tube in the siphon bottle it reaches into the oil zone and when the valve is opened the energy of the expanding gas raises both oil and gas to the surface in the form of a mist or pole now suppose we sink another well in a different location unfortunately we've missed the oil zone well number two is like the shortened tube in the siphon bottle it can produce only gas hence we would leave it shut in we want to conserve the gas energy for driving the oil up well number one as we continue to produce oil and gas from the well the free gas has more room to expand as a result the gas pressure gradually declines the well may flow for months or even years for the decline in gas pressure is inevitable eventually a point is reached where there is no longer sufficient pressure to force the oil to the surface in this case the weld will have to be pumped now we've been talking mainly about lifting oil to the surface but remember the oil must also be moved from various parts of the formation into the well while gas plays an important part in bringing oil into the well there is another penny fields is equally or more effective in this work the driving force of encroaching water this water exerts pressure from below and as oil is produced at the surface the incoming water replaces it in time however the natural forces exerted by water or gas or both may become too weak to move the oil into the well at a sufficient rate well what do you do then well there are several methods of recovering a portion of the oil remaining in the formation they involve what we call repression in one method enormous quantities of gas are pumped back into the formation in this way part of the original cast pressure can sometimes be restored causing the wells to produce at a higher rate in another method large volumes of water are pumped into certain wells this creates an artificial water driving forcing the oil to the other wells well I can see that there's more to this oil business come appears on the surface okay you're right about that now let's step over here for a minute we're gonna take a look out the window there's a modern oil producing field for you the Derrick's have all been removed farm crops growing nearby and no sign of the wells except for a neat little Christmas tree the Christmas tree is simply a group of valves and pressure gauges used to control the flow of oil and gas from the well we try to conserve the natural gas pressures as long as possible by producing the most oil with the least amount of gas of course day by day the gas pressure declines and eventually there won't be enough pressure to force the service what did the well must be pumped there are many different types of oil clumps but they all work on much the same principle my grandma's old fashioned cistern pump only grandma at the goose elbow grease to get the water around monitor pumps are usually driven by pots which used natural gas from the fields for electricity the power plant activates a walking beam which in turn imparts an up-and-down movement to a string of sucker rods [Music] the Circa rods are connected to the pump at the bottom of the well simple valves open and close with the motion of the pump raising the oil to the service boy certainly takes a lot of equipment to produce oil yes and actually you see a part of it well what else can I do for you got time to answer one more question why surely what is it what do you do with the oil after you bring it to the surface well in a word we move it into the refineries here take a look at this model setup I think it'll help answer the question this layup represents the whole business of oil production in a nutshell generally the product of an oil well is a mixture of oil gas and water this mixture flows first to a gas trap the gas trap separates the so-called wet gas from the oil and water leaving the oil for a moment let's follow the wet gas to an absorption plan here the wet gas is literally drive by extracting liquid products such as natural gasoline propane butane and isobutane from the absorb dry gas goes to public utility companies who in turn supply it to homes and industries for heat called manufacturing processes so much for the gas now let's go back to the gas separator and see what happens to the oil after the wet gas has been removed the oil usually flows to a dehydration plant or settling tank which serves to remove water from the oil the treatment and disposal of this unwelcome water is quite a story in itself but let's follow the clean oil now to the filled tank [Music] when these tanks are full the quantity of oil in the tank is measured or aged at the same time samples of the oil are taken from the tanks and sent to a laboratory where tests are made to determine the quality and value of the oil from the filled tanks the gauged and tested oil moves to a pumping station where it is boosted along on the last stage of its journey of the refineries and that's where our job of production ends and the complex job of refining the crude oil into marketable products begins [Music] many men many jobs and all because someone had an idea an idea that expanded into a major industry transforming past years of worthless land into gainful property benefiting thousands of private landowners through the monthly payment of royalties giving birth and sustenance to hundreds of clean orderly communities around oil producing and refining centers and developing a multitude of product products which contributes so much demands comfort in terms of heat power freedom of movement and physical well-being [Music] only time and continuing research on the part of the petroleum industry will reveal what added comforts may be developed for the generations of today and the generations of the days [Music] you
