Abstract
A separation method and apparatus for separating components used in downhole well development activity, whilst in position down the well. Method and apparatus are characterized in that they do not make use of external mechanical forces, or internal fluid pressure, applied through the development apparatus to render the components in a separable state. The release is achieved through the use of a fusible metal element.
