Summary
| Description |
English: Shown are conceptual illustrations of types of oil and gas wells. A vertical well is producing from a conventional oil and gas deposit (right). In this case, a gray confining layer serves to “trap” oil (green) or gas (red). Also shown are wells producing from unconventional formations: a vertical coalbed methane well (second from right); a horizontal well producing from a shale formation (center); and a well producing from a tight sand formation (left). Note: Figure not to scale. Modified from
USGS (2002) and
Newell (2011). |

This geology image could be re-created using
vector graphics as an
SVG file. This has several advantages; see
Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{
vector version available|new image name}}.
It is recommended to name the SVG file “Schematic cross-section of general types of oil and gas resources and the orientations of production wells used in hydraulic fracturing.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
 | This geology image was
uploaded in the
JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the
PNG or
SVG format. If possible, please upload a PNG or SVG version of this image without
compression artifacts, derived from a non-JPEG source (or with existing artifacts
removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for
vectorisation, please tag this image with
{{Convert to SVG}} instead of
{{BadJPEG}}. If not suitable for vectorisation, use
{{Convert to PNG}}. For more information, see
{{BadJPEG}}. |  |
