Wax components can precipitate from petroleum fluids when the original equilibrium conditions of the reservoir are changed so that the solubility of the waxes is reduced; however, wax precipitation does not necessarily lead to deposition. This page discusses wax precipitation behavior and experimental measurements to predict the tendency of a crude oil to precipitate wax.
There are two fundamental problems that make accurately estimating the productivity of a horizontal well more difficult than estimating the productivity of a vertical well. The theoretical models available have a number of simplifying assumptions and the data required for even these simplified models are not likely to be available. Still, we must make estimates and decisions based on those estimates. In this page, two productivity models that have proved useful in practice are discussed.

Biodegradation occurs when bacteria, fungi, or other organism or biological process chemically dissolves materials. The process can be beneficial or detrimental within the industry depending on the circumstances. For instance, biodegradation via bacteria can aid in the cleanup of oil spills.


During biodegradation, microbial organisms metabolize petroleum, degrading the hydrocarbon content. The process can take more or less time depending on the amount of type and amount of bacteria, the reservoir or ecosystem in which the bacteria are found, and the amount of oxygen present.
Microbial Exploration Technology (MET), also called microbial enhanced oil recovery (MEOR), is a method of enhanced oil recovery (EOR) that identifies microorganism levels in soil near reservoir surfaces to estimate hydrocarbon levels. This method is largely based on the premise that the more microorganisms present, the more hydrocarbons are present for those microorganisms to feed on.

Estimating horizontal well productivity

There are two fundamental problems that make accurately estimating the productivity of a horizontal well more difficult than estimating the productivity of a vertical well. The theoretical models available have a number of simplifying assumptions and the data required for even these simplified models are not likely to be available. Still, we must make estimates and decisions based on those estimates. In this page, two productivity models that have proved useful in practice are discussed. Learn more....

Microbial exploration technology


Microbial Exploration Technology (MET), also called microbial enhanced oil recovery (MEOR), is a method of enhanced oil recovery (EOR) that identifies microorganism levels in soil near reservoir surfaces to estimate hydrocarbon levels. This method is largely based on the premise that the more microorganisms present, the more hydrocarbons are present for those microorganisms to feed on.

What is PetroWiki?

PetroWiki was created from the seven volume Petroleum Engineering Handbook (PEH) published by the Society of Petroleum Engineers (SPE). PetroWiki preserves the PEH content in unaltered form (page names that start with PEH:), while allowing SPE's membership to update and expand content from the published version. Pages that do not have PEH: at the beginning may have started with content from the PEH, but have been modified over time by contributors to the wiki.

Content in PetroWiki is moderated by at least two members with subject matter expertise. This helps to ensure that the information found in PetroWiki is technically accurate. Disclaimer

Unlike some other online wikis, PetroWiki content is copyright SPE. For information about using content from PetroWiki, see PetroWiki:Permissions.

How can I contribute to PetroWiki?

PetroWiki is a living document and therefore the content should be enhanced to include newer technologies and current information.

  • Share your knowledge with others and help update PetroWiki at the same time! You can't "break" the wiki.
Follow these basic steps to get started:
Log in
Search for the topic of your choice
Open the topic page
Make changes
Save
  • Adding links to good papers in OnePetro and elsewhere is a great way to enrich existing content pages.
  • Creation of pages about specific fields are welcome. Knowing the basics of the reservoir and how the field was developed over time can provide valuable information to others. (See Prudhoe Bay field and Kuparuk River field as examples)
  • If you are an SPE professional member, you must log in. [Use your SPE website login.] Help with editing
  • Pages that start with PEH: cannot be edited.

For more information, see PetroWiki:Frequently asked questions

Content categorization - SPE has finalized a technical taxonomy that is being used in PetroWiki, OnePetro, and other SPE content.

How do I use PetroWiki?
