A system for sealing a lost circulation zone associated with a subterranean well , the system including: a lost circulation material ; and a lost circulation shape , the lost circulation shape being a hollow body having an outer skin and an open interior chamber, where the outer skin includes a plurality of perforations that extend through the outer skin , providing fluid communication between an exterior of the lost circulation shape and the open interior chamber; the lost circulation shape has a minimum size and a maximum size, where: the minimum size of the lost circulation shape is such that a smallest minimum sphere in which the lost circulation shape having the minimum size could fit has a diameter of 5 mm; and the maximum size of the lost circulation shape is such that a smallest maximum sphere in which the lost circulation shape having the maximum size could fit has a diameter of 15 mm; characterized in that : the plurality of perforations are sized to prohibit a passage of lost circulation material between the exterior of the lost circulation shape and the open interior chamber; and the lost circulation shape includes a filling hole , the filling hole extending through the outer skin and having a diameter in a range of 2.5 mm to 5 mm. a lost circulation material ; and a lost circulation shape , the lost circulation shape being a hollow body having an outer skin and an open interior chamber, where the outer skin includes a plurality of perforations that extend through the outer skin , providing fluid communication between an exterior of the lost circulation shape and the open interior chamber; the lost circulation shape has a minimum size and a maximum size, where: the minimum size of the lost circulation shape is such that a smallest minimum sphere in which the lost circulation shape having the minimum size could fit has a diameter of 5 mm; and the maximum size of the lost circulation shape is such that a smallest maximum sphere in which the lost circulation shape having the maximum size could fit has a diameter of 15 mm; characterized in that : the plurality of perforations are sized to prohibit a passage of lost circulation material between the exterior of the lost circulation shape and the open interior chamber; and the lost circulation shape includes a filling hole , the filling hole extending through the outer skin and having a diameter in a range of 2.5 mm to 5 mm. the minimum size of the lost circulation shape is such that a smallest minimum sphere in which the lost circulation shape having the minimum size could fit has a diameter of 5 mm; and the maximum size of the lost circulation shape is such that a smallest maximum sphere in which the lost circulation shape having the maximum size could fit has a diameter of 15 mm; characterized in that : the plurality of perforations are sized to prohibit a passage of lost circulation material between the exterior of the lost circulation shape and the open interior chamber; and the lost circulation shape includes a filling hole , the filling hole extending through the outer skin and having a diameter in a range of 2.5 mm to 5 mm. the plurality of perforations are sized to prohibit a passage of lost circulation material between the exterior of the lost circulation shape and the open interior chamber; and the lost circulation shape includes a filling hole , the filling hole extending through the outer skin and having a diameter in a range of 2.5 mm to 5 mm. <EOS>
