Claims10
A method to prevent lost circulation of a drilling fluid in a wellbore, comprising:
- introducing an altered drilling fluid into the wellbore while drilling such that a loss prevention material (LPM) contacts a loss zone, wherein the altered drilling fluid comprises the drilling fluid and the LPM, wherein the LPM consists of:
- a first plurality of particles produced from date tree seeds;
- a second plurality of particles produced from date tree rachis, date tree leaves, or a combination thereof, and
- a third plurality of particles produced from scrap tires;
- blocking the loss zone with the LPM and thereby preventing lost circulation of the drilling fluid in the wellbore.
