Abstract
A treatment fluid can include a base fluid and a lost-circulation package. The lost-circulation package can include plurality of pieces of a first lost-circulation material and a second lost-circulation material. The plurality of pieces can be an open-cell, natural or biodegradable material, for example natural sponges such as loofah. The plurality of pieces can enter permeable areas of a subterranean formation and form a mesh-like matrix that the second lost-circulation material can be retained within. The second lost-circulation material can be insoluble particles such as ground walnut shells or include ingredients that form a cementitious substance. The first and second lost-circulation materials can form a plug and provide adequate fluid loss control. The treatment fluid can be used in an oil and gas operation.
