Composition and method of manufacturing of whole date palm seed lost circulation material (LCM)
A lost circulation material (LCM) that includes whole date palm seeds. The whole date palm seeds LCM includes date palm seeds having lengths greater than 22.6 millimeters (mm), date palm seeds having lengths in the range of 16 mm to 22.6 mm, and date palm seeds having lengths in the range of 1 mm to less than 16 mm. Method of manufacturing the whole date palm seeds LCM include washing and drying whole date palm seeds, such that the drying includes air-drying, hot rolling, and cooling. Methods of reducing lost circulation are also provided.
Breaking a fracturing fluid to prop a fracture in a subterranean formation
Methods of treating a subterranean formation. A pad fluid is introduced into a wellbore penetrating the subterranean formation to create or enhance one or more fractures in the subterranean formation. A fracturing fluid is introduced into the wellbore. The fracturing fluid includes a polymer having a hydrophobic monomer and a hydrophilic monomer. The fracturing fluid further includes a proppant and a second aqueous base fluid. The fracturing fluid does not include a crosslinker or an oxidative breaker. The fracturing fluid is broken thereby settling the proppant in the fracture.
Coated lost circulation materials and methods of using same
A method of reducing fluid loss includes pumping a wellbore fluid including resin coated solid particulate into a wellbore having fractures therein, the resin coated solid particulate forming a substantially impermeable plug in the fractures. A method of drilling a wellbore includes drilling a wellbore through a formation using a first wellbore fluid; and upon experiencing a fluid loss event to the formation, pumping a second wellbore fluid including resin coated solid particulates into the wellbore.
De-oiled lost circulation materials
De-oiled lost circulation materials and methods of using such materials to, for example, reduce fluid loss are provided. In some embodiments, such methods include introducing a first treatment fluid including a base fluid and a de-oiled plant material into a wellbore penetrating at least a portion of a subterranean formation including a loss zone; and allowing the de-oiled plant material to at least partially plug the loss zone.
Protection of Structures with Subterranean Injection of Lignocellulosic Solids
A method for altering a characteristic of the ground. The method comprises the steps of preparing a lignocellulosic material, suspending the lignocellulosic material in a slurry to create a lignocellulosic slurry, and creating a fluid movement of the lignocellulosic slurry. The method further includes the steps of resuspending a portion of the lignocellulosic slurry with the fluid movement; and injecting the lignocellulosic slurry below the surface of the ground.
WELL TREATMENT FLUID HAVING BIODEGRADABLE FLUID LOSS CONTROL AGENT
A method of treating a well that includes introducing a well treatment fluid into the well, and a well treatment fluid, are provided. The well treatment fluid comprises an aqueous base fluid, a bridging agent, a viscosifying agent, and a water soluble, biodegradable graft copolymer. In one embodiment, for example, the method is a method of cementing a casing in a well. In this embodiment, the well treatment fluid is a cement spacer fluid.
Date seed-based chips lost circulation material
A lost circulation material (LCM) that includes chips formed from date palm seeds. The date palm seed-based chip LCM includes chips having lengths in the range of greater than 2.38 millimeters (mm) to less than 6.73 mm. Method of manufacturing the date palm seed-based chip LCM include washing and drying whole date tree seeds, such that the drying includes air-drying, hot rolling, and cooling. Methods of reducing lost circulation are also provided.
USE OF ULTRA LIGHTWEIGHT PARTICULATES IN MULTI-PATH GRAVEL PACKING OPERATIONS
A well penetrating a subterranean formation may be subjected to a multi-path gravel packing operation by using a fluid containing an ultra lightweight particulate having an apparent specific gravity less than or equal to 2.45 which is substantially neutrally buoyant in a carrier fluid. The fluid is flowed through one or more transport tubes which, with a gravel packing screen, constitute a screen assembly. A gravel pack is formed onto the screen of the screen assembly in-situ.
Liquid Sand Treatment Optimization
A method of hydraulic fracturing may comprise mixing at least one liquid sand mixture with a fluid to produce a fracturing fluid; and conveying the fracturing fluid to two or more wellbores simultaneously, wherein the wellbores penetrate a subterranean formation.
Flaky date fruit 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.
