  • Offshore oil and natural gas in depth - U. S. Energy Information . . .
    Offshore oil rig Source: Stock photography (copyrighted) Offshore oil and natural gas wells are drilled from platforms that hold the drilling equipment, storage areas, and housing for work crews Some drilling platforms stand on stilt-like legs that are embedded in the ocean floor
  • U. S. Oil and Natural Gas Wells by Production Rate
    Overview Technological innovation in drilling and completions has resulted in growth in U S oil and natural gas production over the last 15 years Exploring how U S oil and natural gas wells have changed provides deeper insight into this rapid growth In this report, we present data on the distribution of wells by size and technology and analyze emerging trends In December 2023, U S oil
  • Horizontally drilled wells dominate U. S. tight formation production - U . . .
    Source: U S Energy Information Administration, based on Drillinginfo Note: Vertical well production also includes wells created by directional drilling and by unknown drilling type Tight oil volumes include liquid production from shale gas formations, and shale gas totals include natural gas volumes from the tight oil formations
  • Where our oil comes from in depth - U. S. Energy Information . . .
    Oil may flow to the earth's surface from natural pressure in the rock formation, or it may have to be forced out of the ground and up through a well The type of geologic formation where the oil is located determines the technologies used to start the flow of oil and natural gas from the reservoir or resource-bearing rock into the wells
  • Quantifying Drilling Efficiency
    This is the total footage drilled yearly for oil wells, gas wells, and dry holes divided by the number of active rigs operating during a study year However, results depend on establishing a representative “active” annual rig count which is an imprecise and subjective task
  • Rapid declines from horizontal wells require more drilling to sustain . . .
    Between 2010 and 2024, hydrocarbon production from new wells in the Lower 48 states (L48) generally offset and exceeded declining production from existing wells Because production from oil and natural gas wells declines over time as reservoir pressure decreases, new wells are required to maintain the same production level
  • Nearly all new U. S. crude oil and natural gas wells are horizontal or . . .
    The data series recently added to our Monthly Energy Review (MER) provide information on crude oil and natural gas well completions and drilled footage for U S wells completed since 2010 In 2021, 81% of U S well completions were horizontal or directional, as opposed to 19% of wells that were drilled vertically Horizontal and directional wells involve drilling a vertical well and then, at a
  • Trends in U. S. Oil and Natural Gas Upstream Costs
    Price developments are readily observable in markets for oil and natural gas, while trends in well productivity are tracked by many sources, including EIA’s Drilling Productivity Report which focuses on well productivity in key shale gas and tight oil plays
  • Petroleum Other Liquids Data - U. S. Energy Information Administration . . .
    Crude oil, gasoline, heating oil, diesel, propane, and other liquids including biofuels and natural gas liquids Exploration and reserves, storage, imports and exports, production, prices, sales Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand emissions
  • Drilling Productivity Report - U. S. Energy Information Administration (EIA)
    The Drilling Productivity Report (DPR) rig productivity metric new-well oil natural gas production per rig can become unstable during periods of rapid decreases or increases in the number of active rigs and well completions The metric uses a fixed ratio of estimated total production from new wells divided by the region's monthly rig count, lagged by two months The metric does not represent
