SALT TOLERANT SETTLING RETARDANT PROPPANTS
A method of treating a subterranean formation including suspending proppant particulates in a treatment fluid, wherein the proppant particles include a coating comprising a salt-tolerant, water-swellable polymer, and the treatment fluid includes at least one fluid consisting of fresh water, salt water, seawater, brine, an aqueous salt solution, and combinations thereof; and introducing the treatment fluid containing the settling retardant proppant particulates into the subterranean formation. A composite proppant particle includes a proppant substrate and a salt tolerant polymeric layer deposited on the proppant substrate.
Date Tree Waste-Based Compound Fibrous LCMs
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.
Flaky Date Fruit Qulansuwa (CAP) for Moderate to Severe Loss Control
A lost circulation material (LCM) having date fruit caps is provided. The date fruit cap LCM includes date fruit caps from a date tree. The date fruit caps have multiple flakes (for example, three flakes) attached at one end to an end cap and free at the other end. The date fruit caps may be obtained from the waste product of date tree and date fruit processing. The date fruit cap LCM may be added to a drilling fluid (for example, a drilling mud) to mitigate or prevent such lost circulation in a well. Methods of lost circulation control with the date fruit cap LCM are also provided.
Date tree waste-based compound fibrous LCMs
An altered drilling fluid having a drilling fluid and a date tree waste-based lost circulation material (LCM). The date tree waste LCM may include includes date tree waste fibers produced 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 manufacture of a date tree waste LCM are also provided.
Wellbore servicing fluids and methods for controlling fluid losses in permeable zones
A method of servicing a wellbore penetrating a subterranean formation, the method including placing a wellbore servicing fluid into the wellbore proximate a permeable zone. The wellbore servicing fluid comprises a base fluid and from about 3 wt. % to about 25 wt. % by total weight of the wellbore servicing fluid of a particulate material. The particulate material comprises palm kernel shells.
Compressed lost circulation materials
Compressed lost circulation materials for use in subterranean formations are provided. In some embodiments, the methods include: introducing a treatment fluid that includes a base fluid and a compressed lost circulation material into a wellbore penetrating at least a portion of a subterranean formation including a loss zone, the compressed lost circulation material including a binding material and a compressed material; allowing the binding material to at least partially degrade or dissolve; and allowing the compressed lost circulation material to at least partially expand in the subterranean formation.
Method of Removing Non-Aqueous Drilling Mud with Banana Containing Fluid
Non-aqueous drilling fluids may be removed from a wellbore or tubing nor casing within the wellbore by introducing into the well a biodegradable aqueous fluid comprising banana.
SURFACTANT IMPREGNATED LOST CIRCULATION, SCRUBBING, AND SCOURING MATERIAL
A solid surfactant composition includes a water-wetting surfactant and a plant fiber carrying agent. A process includes forming a solid surfactant composition comprising a water-wetting surfactant and a plant fiber carrying agent and injecting the solid surfactant composition into a wellbore.
SPHERICAL HIGH TEMPERATURE HIGH CLOSURE TOLERANT CASHEW NUT SHELL LIQUID BASED PROPPANT, METHODS OF MANUFACTURE, AND USES THEREOF
A method of fracturing a subterranean formation comprises introducing into the formation at a pressure sufficient to create or enlarge a fracture in the formation a fracturing composition comprising a carrier and a substantially spherical polymeric particulate derived from a cashew nut shell liquid, the substantially spherical polymeric particulate having an apparent specific gravity of less than about 2.4.
METHODS OF USING LIGHTWEIGHT POLYMERS DERIVED FROM CASHEW NUT SHELL LIQUID IN HYDRAULIC FRACTURING AND SAND CONTROL OPERATIONS
A method of fracturing a subterranean formation comprises introducing into the formation at a pressure sufficient to create or enlarge a fracture in the formation a fracturing composition comprising a carrier and a polymeric particulate derived from a cashew nut shell liquid, the polymeric particulate having an apparent specific gravity of less than about 2.4.
