|Reservoir inflow in underbalanced drilling
In underbalanced drilling (UBD), as soon as the bit penetrates the reservoir, reservoir fluids start to flow into the wellbore. At this stage, the stabilized multiphase flow regime in the well prior to reservoir fluid entry must be adjusted to account for inflow and minimize the impact to the circulation system or moving out of the UBD window already established.

Autonomous underwater vehicles (AUVs) are programmable robots that function independently from operator input. For the purposes of the oil and gas industry, AUVs are primarily used to survey seafloors before subsea infrastructures are built, to build subsea infrastructures and pipelines, and to survey pipelines after completion. AUVs can provide a less costly and invasive alternative to traditional surveying methods.
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.
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.
