Abstract
A date tree trunk-based lost circulation material (LCM) is provided. The date tree trunk LCM includes date tree trunk fibers produced from date tree trunks. The date tree trunks may be obtained from the date tree waste produced by the processing of date trees in the production of date fruits. The date tree trunk LCM may include fibers having lengths less than 8 millimeters (5 mm) and having an aspect ratio range of 10 to 15. Methods of lost circulation control using a date tree trunk LCM and manufacture of a date tree trunk LCM are also provided.
Claims11
An altered drilling fluid, comprising:
- a drilling fluid, wherein the drilling fluid comprises a gel-polymer mud or a volcanic ash-based mud;
- and
- a lost circulation material (LCM), wherein the LCM comprises a plurality of date tree trunk fibers produced from date tree trunks.
A method of forming a lost circulation material (LCM), comprising:
- chopping a plurality of date tree trunks to produce a plurality of chopped date tree trunks;
- washing the plurality of chopped date tree trunks using water;
- grinding the chopped date tree trunks to produce a plurality of date tree trunk fibers, the LCM consisting of the date tree trunk fibers, wherein the plurality of date tree trunk fibers comprise a plurality of untreated date tree trunk fibers that are not introduced to an alkali, an acid, a bleaching or an oxidation agent.
A lost circulation material (LCM) composition, the composition consisting of:
- a plurality of date tree trunk fibers produced from a date tree trunk, wherein the plurality of date tree trunk fibers comprise a plurality of untreated date tree trunk fibers that are not introduced to an alkali, an acid, a bleaching or an oxidation agent.
