Rapidly dehydrating lost circulation material (LCM)
A rapidly dehydrating lost circulation material (LCM) composition is provided. The LCM composition may include a carrier fluid, volcanic ash, a viscosifier, and date tree rachis fibers. The carrier fluid may be water and the viscosifier may be a cellulosic microfiber. The LCM composition may form a rapidly dehydrating loss control slurry (RDLCS). The LCM composition may be formed by mixing the carrier fluid, the volcanic ash, the viscosifier, and the date tree rachis fibers in a mixer to form a homogenous mixture. Methods of lost circulation control and manufacture of a rapidly dehydrating LCM are also provided.
1. A lost circulation material (LCM) composition, the composition comprising:
a carrier fluid;
a particulate material comprising volcanic ash;
a viscosifier; and
a fibrous material comprising date tree rachis fibers, wherein the date tree rachis fibers comprise at least 6% by weight of the LCM composition.
2. The LCM composition of claim 1 , wherein the carrier fluid, the particulate material, the viscosifier, and the fibrous material form a homogenous mixture.
3. The LCM composition of claim 1 , wherein the carrier fluid comprises water.
4. The LCM composition of claim 1 , wherein the viscosifier comprises a cellulosic microfiber.
5. The LCM composition of claim 1 , wherein the particulate material consists of volcanic ash.
6. The LCM composition of claim 1 , wherein the fibrous material consists of date tree rachis fibers.
7. The LCM composition of claim 1 , wherein the LCM composition has a dehydration time of less than 3 minutes at 100 pounds-per-square inch differential (psid) pressure.
8. The LCM composition of claim 1 , wherein the volcanic ash comprises at least 6% by weight of the LCM composition.
9. An altered drilling fluid, comprising:
a drilling fluid; and
a lost circulation material (LCM) composition, wherein the LCM composition comprises:
a carrier fluid;
a particulate material comprising volcanic ash; a viscosifier; and
a fibrous material comprising date tree rachis fibers, wherein the date tree rachis fibers comprise at least 6% by weight of the LCM composition.
10. The altered drilling fluid of claim 9 , wherein the carrier fluid comprises water.
11. The altered drilling fluid of claim 9 , wherein the viscosifier comprises a cellulosic microfiber.
12. The altered drilling fluid of claim 9 , wherein the particulate material consists of volcanic ash.
13. The altered drilling fluid of claim 9 , wherein the fibrous material consists of date tree rachis fibers.
14. A method of forming a lost control material (LCM) composition, comprising:
adding a carrier fluid to form a mixture;
adding a particulate material to the mixture, the particular material comprising volcanic ash;
adding viscosifier to the mixture; and
adding a fibrous material to the mixture to form the LCM composition, the fibrous material comprising date tree rachis fibers, wherein the date tree rachis fibers comprise at least 6% by weight of the LCM composition.
15. The method of claim 14 , wherein the LCM composition comprises a homogenous mixture.
16. The method of claim 14 , wherein the carrier fluid comprises water.
17. The method of claim 14 , wherein the viscosifier comprises a cellulosic microfiber.
