What is a infill well?

In oil and gas production, an infill well is a well drilled within the boundaries of an existing field, typically to exploit bypassed or undrained reserves. Infield wells are typically drilled in areas where there is known to be producible hydrocarbons, but where the existing wells are not able to fully drain the reservoir. Infill wells can also be used to improve the recovery of hydrocarbons from an existing reservoir by increasing the number of production wells and/or by changing the production strategy.

Infill wells are drilled for several reasons, including:

* To increase production from an existing field

* To improve recovery from an existing reservoir

* To exploit bypassed or undrained reserves

* To develop new reservoirs within an existing field

* To test the potential of a new area within an existing field

The benefits of infill wells include:

* Increased production from an existing field

* Improved recovery from an existing reservoir

* Access to new reservoirs within an existing field

* Reduced risk compared to drilling a new field

* Lower cost than drilling a new field

The risks of infill wells include:

* The potential to damage existing wells

* The potential to encounter unexpected subsurface conditions

* The potential for increased environmental impact

Infill wells are an important tool for oil and gas companies to increase production from existing fields and improve recovery from existing reservoirs. They can also be used to exploit bypassed or undrained reserves and develop new reservoirs within an existing field. Infill wells are a cost-effective way to increase production and reduce risk compared to drilling a new field.
