Abstract
A date tree waste-based lost circulation material (LCM) is provided. The date tree waste LCM may include includes fibers from the date tree waste produced from processing date trees in the production of date fruits. The date tree waste may include fibers from one or more of the following: date tree trunks, date tree rachis, date tree leaflets, date tree panicles, and date tree roots. The date tree waste LCM may include fibers having lengths in the range of 5 millimeters (5 mm) to 15 mm, diameters in the range of 0.5 mm to 0.8 mm, and having an aspect ratio range of 6 to 30. Methods of lost circulation control using and manufacture of a date tree waste LCM are also provided.
Claims28
A method to control lost circulation in a lost circulation zone in a wellbore, comprising:
- introducing an altered drilling fluid into the wellbore such that the altered drilling fluid contacts the lost circulation zone and reduces a rate of lost circulation into the lost circulation zone, where the altered drilling fluid comprises a drilling fluid and a lost circulation material (LCM), wherein the LCM comprises a plurality of date tree waste fibers produced from date tree waste, wherein the date tree waste comprises waste from date palm processing.
An altered drilling fluid, comprising:
- a drilling fluid;
- and
- a lost circulation material (LCM), wherein the LCM comprises a plurality of date tree waste fibers produced from date tree waste, wherein the date tree waste comprises waste from date palm processing.
A lost circulation material (LCM) composition, the composition comprising:
- a plurality of date tree waste fibers produced from date tree waste, wherein the date tree waste comprises waste from date palm processing, wherein the date tree waste comprises at least one of:
- date tree trunks, date tree rachis, date tree leaves, date tree leaflets, and date tree root.
A method of forming a lost circulation material (LCM), comprising:
- grinding date tree waste to produce a plurality of date tree waste fibers, wherein the date tree waste comprises waste from date palm processing and further comprises at least one of:
- date tree trunks, date tree rachis, date tree leaves, date tree leaflets, and date tree roots;
- and
- mixing the plurality of date tree waste fibers to form a homogenous mix of the date tree waste fibers, the LCM comprising the homogenous mix.
