Biodegradable and acid soluble materials for control of loss of circulation in reservoir drilling operations

A method of controlling lost circulation in a lost circulation zone in a wellbore, the method comprising:

• introducing a lost circulation pill in the wellbore, and
• forming a plug from the lost circulation pill in the lost circulation zone,
• the lost circulation pill comprising, based on a total weight of the lost circulation pill,
• about 0.1 to about 2 weight percent of a luffa component comprising at least one of a luffa fiber or luffa sponge;
• about 10 to about 30 weight percent of a combination of a sized carbonate and a sized degradable synthetic material in a ratio of 10:90 to 30:70, in the form of particles, flakes, fibers, or a combination thereof;
• about 0.1 to about 10 weight percent of a degradable viscosifier based on the total weight of the lost circulation pill, wherein the degradable viscosifier comprises at least one of xanthan gum, polysaccharide, a viscoelastic surfactant, hydroxyethyl cellulose or a diallyldimethylammonium chloride;
• and
• about 60 to about 90 weight percent of a brine;
• wherein the sized carbonate comprises:
• first carbonate particles having a D50 of about 1100 to about 1200 microns, present in an amount of about 10 to about 20 weight percent based on the total weight of the sized carbonate;
• second carbonate particles having a D50 of about 600 to about 700 microns, present in an amount of about S to about 15 weight percent based on the total weight of the sized carbonate;
• third carbonate particles having a D50 of about 200 to about 300 microns, present in an amount of about 5 to about 15 weight percent based on the total weight of the sized carbonate;
• and
• optionally, fourth carbonate particles having a D50 of about 10 to about 30 microns.
