Environmental Benefits of Advanced Oil & Gas exploration


Quiz Questions

1.The Gulf of Mexico’s coastal transition zone is among the most prospective, unexplored oil and gas regions in the country.
True
False
2. Improvements in 3-D seismic and 4-D time-lapse visualization, remote sensing, and other exploration technology allow explorationists to target higher-quality prospects and to improve success rates by as much as 50 percent or more.
True
False
3.Natural gas is not converted to barrels of oil equivalent on the basis of 0.178 barrels of oil per thousand cubic feet of gas.
True
False
4.The volume of reserves added per exploratory well has decreased dramatically since the 1970s and early 1980s.
True
False
5.New deepwater drilling technology enables exploratory drilling in ever deeper offshore waters, making promising new resources accessible for the first time.
True
False
6.At BP Amoco/Shell’s Foenhaven field, estimated recovery rates of oil-in-place are expected to reach 65 to 70 percent with 4-D seismic, compared to 25 to 30 percent with 2-D technology and 40 to 50 percent with 3-D technology.
True
False
7.Advances in 3-D and 4-D seismic technology and earth-imaging systems have not helped in the understanding of subsurface fluid flow, not just for oil and gas, but for groundwater monitoring and pollutant transport.
True
False
8.Successful drilling often means going faster and deeper through harder rock and in multiple directions from a single wellbore.
True
False
9.With horizontal drilling, today’s oil and gas industry does not have the extraordinary capability: the power to navigate three-dimensionally through the earth, contacting and economically producing resources while minimizing surface disruption.
True
False
10._________________ is the moment of truth for oil and gas producers.
Drilling
Plumbing
Production
11.High technology has migrated to almost all phases of exploration and production, and that includes stepping right up to the drilling rig floor.
True
False
12.Contacting a targeted formation does not involve:

  • Using rotary equipment and hardened drill bits, weighted and lubricated by drilling fluids, to penetrate the earth’s surface.
  • Inserting casing and tubing into each well to protect the subsurface and control the flow of fluids (oil, gas, and water) from the reservoir.
True
False
13.Environmental benefits of horizontal and directional drilling include: Fewer wells, Lower waste volumes and protection of sensitive environments.
True
False
14.__________________________ is a technique i.e. gaining widespread use for tapping into reserves in mature fields and significantly decreases waste volumes.
Slimhole drilling
Coiled tubing
15.Environmental benefits of slimhole drilling and coiled tubing include: Higher waste volumes, larger footprints and increased noise and visual impacts.
True
False
16.Coiled tubing technology is a cost-effective solution for drilling in reentry, underbalanced and highly deviated wells.
True
False
17.Environmental benefits of annular injection of cuttings do not include- lower toxicity of discharges and protection of sensitive environments.
True
False
18.Air percussion or pneumatic drilling used for natural gas wells in regions such as Appalachia can eliminate the need for drilling liquids during drilling operations.
True
False
19.The phase secondary recovery in the Oil and Gas Recovery Process produces oil, gas, and/or water using the natural pressure in the reservoir.
True
False
20.Caliche, the crust of calcium carbonate that forms on the stony soil of arid regions, is not common in drilling pads and pits in many oil fields in Texas.
True
False
