Transcript: Thank You! Well Life Cycle Well Life Cycle Planning Planning Formulate a program for drilling a well that has the following characteristics: 1. Safe 2. Minimum cost 3. Usable Unfortunately, it is not always possible to accomplish these objectives on each well because of constraints based on geology, drilling equipment, temperature, casing limitations, hole sizing, or budget. Objective Objective - Highest priority in well planning - Personnel considerations must be placed above all other aspects of the plan - Safety of the well - Designed to minimize the risk of blowouts and other future problem factors Safety Safety - Minimize cost of the well without jeopardizing the safety aspects - Costs can be reduced to a certain level as additional effort is given to the planning Minimum Cost Minimum Cost - Drilling a hole to the target depth is unsatisfactory if the final well configuration is not usable. - Term "usable" implies the following: 1. The hole diameter is sufficiently large so an adequate completion can be made. 2. The hole or producing formation is not irreparably damaged. Usable Holes Usable Holes The drilling engineer is required to plan a variety of well types, including: 1. Wildcats 2. Exploratory holes 3. Step-outs 4. In-fills 5. Re-entries. Generally, wildcats require more planning than the other types. Infill wells and re-entries require minimum planning inmost cases. Well-Type Classification Well-Type Classification - Unproven area - No concrete historic production records - Unexplored as a site for potential oil and gas output Wildcat Well Wildcat Site selection based on seismic data or satellite survey Exploratory Well Exploratory - Delineates the reservoir boundaries - Drilled after the exploratory discoveries - Site selection usually based on seismic data Step-out (Development) Well Step-out (Development) - Adding new wells in an existing field within the original well patterns - Accelerate recovery or to test recovery methods - Used to confirm the presence of hydrocarbon between the step-out drill holes In-Fill Well In-Fill - Existing well re-entered to deepen, side track, rework, or re-complete - Various amount of planning is required - Depending on the purpose of the re-entry Re-entry Well Re-entry The formation, or pore, pressure encountered by the well significantly affects the well plan. The pressures may be normal, abnormal (high), or subnormal (low). Formation Pressure Formation Pressure - Generally do not create planning problems - The mud weights are in the range of 8.5 to 9.5 lb./gal - Kicks-and blowout-prevention problems should be minimized - Casing requirements can be stringent even in normal-pressure wells deeper than 20,000 ft. because of tension/collapse design constraints Normal-pressure Wells Normal-pressure - May require setting additional casing strings to cover weak or low-pressure zones - The lower-than-normal pressures may result from geological or tectonic factors or from pressure depletion in producing intervals Subnormal-pressure Wells Subnormal-pressure - Affect the well plan in many areas, including: 1. Casing and tubing design 2. Mud-weight and type-selection 3. Casing-setting-depth selection 4. Cement planning - Following problems must be considered as a result of high formation pressures 1.Kicks and blowouts 2. Differential-pressure pipe sticking 3. Lost circulation resulting from high mud weights Abnormal pressures Wells Abnormal pressures Drilling Drilling The well is created by drilling a hole into the earth using a drilling rig that rotates a string with a bit attached To Drill you Need : 1. A way to descend; drill pipe 2. A way to rotate the pipe; "Kelly" or top drive - Kelly or Rotary: rotation is achieved by turning a square or hexagonal pipe (the "Kelly") at drill floor level. - Top Drive: rotation and circulation is done at the top of the drill string, on a motor that moves in a track along the derrick. 3. A place to hold the pipes; derrick 4. A way to raise & lower the pipe; draw works 5. A cutting tool; bit 6. A media to remove cuttings; mud Objectives Objectives - Variety of configurations and designs - For different surface environments that range from; 1. Arctic 2. Desert 3. Ocean 4. Mid-continent 5. Everything in between Types of Rigs Types of Rigs Land or Onshore Rigs Offshore Rigs Offshore Rigs - Or a self-elevating unit is a type of mobile platform - Consists of a buoyant hull fitted with a number of movable legs. - Depth Range from few feet to over 400 feet Jack-up Rigs Jack-up Rigs - Supported on large pontoon-like structures - Provide buoyancy allowing the unit to be towed from location to location. - Once on the location, the pontoon structure is slowly flooded until it rests securely on its anchors, of which there are usually two per corner. - Operating deck is elevated 100 feet above the pontoons on large steel columns to provide clearance above the waves. - After the well is drilled, the water is pumped out of the buoyancy tanks and the - -

Transcript: Oil and Gas We interviwed Haley's grandfater who has worked at the refinery for more than 20 years. Interview! Question 1- How long have you worked at the refinery? 1.Since 1989, 23 years Question 2- What position did you start out at? 2. As a process operator Question 3- Have you always worked in the same position? If not what other positions have you experienced? 3. I have worked in nine different postions, process operator, operations maintenance coordinator, in this position I prioritized the work in maintenance in regards to what gets done first. I also worked as an area day supervisor, where I was supervising all of the shift supervisors and daily instructions to keep the plant running, I worked in this position for 2 years. I then worked as an operations shift super intendant where I was placed on a 4 shift cycle, working 5 days, 5 nights, etc. I then took on the position of a turn around super intendent transferred to days when the refinery had a total shut down. I put in charge of the shut down, organizing and planning of execution of the shut down until it came back up again, I did this for 3 years. Then I moved to the position of production manager, I was the head of production in the process area, the area in which all of the crew is refined, I had supervisors and superintendents reporting to me. Then, I became the off sites and terminal manager for blending of petroleum products and shipping of the products, I was in charge of what went on all the ships and what came off all the ships I stayed in this position for 8 years. I then became the turn around manager, I was responsible for all the contractors and work force in getting the turnaround executed on budget and on time as safely as possible. In 2008 I became the field services manager that looked after all the maintenance of the refinery, I had 175 people reporting to me in my department. I am now one of the 4 senior managers at the refinery responsible for all maintenance turnaround and reliability, I have all managers from departments reporting to me and under the department there are 15 supervisors, 4 superintendants 7 planners and 180 craft people. The refinery is divided into 4 sections, I am responsible for the maintenance turn around and liability, Another is responsible for operations of the refinery, Another is responsible for the production of the crude and sales of the products and another is responsible for all engineering and capital investments. Facts Facts about the refinery: The refinery employs 600 people It is a 115 000 barrels per day oil refinery The refinery was built from 1970-1973 First shipment of crude was received in May of 1973 The refinery have a tank storage capacity of 7 and a half million barrels They receive crude from the Middle East, Asia and Russia and a small portion sometimes from the grand banks of Newfoundland. Only because the crude from Newfoundland is light, while they are a heavy crude refinery 10% of their products are sold in Newfoundland and the remaining 90% is exported to the United States and the eastern seaboard and Europe. The refinery produces furnace oil, ultra low sulphur diesel, jet fuel, gasoline, propane, butane and ships bunkers known as six oil, butane we blend into the gasoline to make a higher octane. The main reason the refinery was chosen at Come by Chance is because we have the deepest salt water, ice free port in North America therefore the ships can dock directly at the terminal rather than having smaller ships offload the bigger ships and transport it to the terminal also because the refinery is very close to 80% of the North American, South American and European markets it's a 7 day sail from the North Sea, 3 day sail from New York harbour, and 14 day sail from the middle east, via the Mediterranean The refinery receives crude tankers that has a capacity of 3 million barrels of crude The refinery works with the college of the North Atlantic and Memorial University in students requiring work terms, they take them and teach them the different skills within the refinery pertaining to their degree/trade.

Transcript: I like this career because I am interested in math and science and I like learning new things and it is a well paying job. Some things I dislike about this career are the long hours and the work conditions at times. I do not think I am suited for this career and I do not think that I would consider it as a career possibility because I am not interested in living and working in remote areas for periods of time. Some other Jobs like this one are: Some other jobs like a geologist are: mineralogist, petrologist and a geochemist. I think this is about facts! Working Conditions of a Geologist: Ocupational Outlook: Geologists are employed by consulting firms, government agencies, museums, academic institutions, and environmental and mining companies. Geologists mostly work indoors in offices and labs, but many also spend time working outdoors in the field in all weather conditions. They may have to live in tents or other rudimentary shelters for sevral weeks while doing field work. This type of work is sometimes done in foreign countries, in extremely remote and occasionally inhospitable areas and in all weather conditions. (Rain, Snow, Sun) They may also spend some time at rig sites. The average geologist works 8 to 9 hours a day. During fieldwork, they may work 12 to 14 hours a day, often 7 days a week. By: Katie Gaulton To be a geologist you must be patient since geological finds often take years, curious, logical, good with people, physically and mentally tough and interested in science and math, excellent decision making skills, the ability to visualize three-dimensional objects from two-dimensional drawings and the ability to work well in a team environment. You must be accurate and good at researching, writing, and creating graphs. It’s also important to have the technical knowledge needed to understand the necessary equipment. Thank you for your attention! Geologists are scientists who study the history and structure of the earth’s crust and the rocks and minerals that form it. Would I be suited for this job and consider it asd a career possibility? Why or why not? Salary of a geologist: To become a geologist you must have at least a university bachelor’s degree in geology or a related subject. Many have a master’s degree or a PhD. You must register with a professional association to practise independently in some areas. A master’s degree is usually the minimum requirement for entry-level research positions in private industry and government agencies. A PhD is necessary for most high-level research positions and to teach geology in universities or colleges. It usually takes 1 to 2 years to earn a master’s degree, and 4 to 5 years to complete a PhD. Geologists examine and identify rocks and minerals. They also prepare maps that show rock types and geological structures. They advise builders and engineers on the suitability of sites for building or mining projects. Many geologists locate new oil fields and mineral deposits, and devise ways to access them. Some teach geology at universities aswell. Geologists use a myriad of advanced techniques in order to find commercial accumulations of oil and gas. The salary of a geologist varies between$15.27 to $117.79 an hour. The average wage is $55.99 an hour. Things I like and dislike about this career: Jobs in the oil and gas industry. Job Description: Educational Requirements: The number of job openings in geology depend on: The time of year, trends and events affecting overall employment, employment turnover (work opportunities generated by people leaving existing positions), occupational growth (work opportunities resulting from the creation of new positions that never existed before) and the size of the occupation. Between 2011 and 2015 the average occupational outlook is 2.7% per year. In geology there are many different jobs: ex. consulting firms resource, exploration, engineering and environmental companies government departments and agencies science centres and museums. Personal Characteristics/Abilities Needed for this career: Geologist
