Petropedia explains Drillable

In the oil and gas industry, Drillable is a term used for drilling packers and equipment that are used in a wellbore. These Drillable packers and tools placed inside the oil wellbore are made from high quality material and the material selection varies from the intended use. Metals such as aluminum and cast iron are preferred, whereas brittle and soft materials such as plastic can also be used to make the drillable packer. A drillable packer is a permanent assembly tool and once it is left inside the wellbore it can only be removed by conducting a drilling operation. These Drillable tools are mostly used in the well completion phase of an oil well.
