A 3D printed proppant includes a core having support bars extending from the core to a shell, the shell encapsulating the core and the support bars. Another 3D printed proppant includes a porous core and a shell encapsulating the porous core, where the porous core has a porosity from 25% to 75%. The 3D printed proppant has a particle size from 8 mesh to 140 mesh. The core, the support bars, the porous core, the shell, or combinations thereof includes metal, polymer, ceramic, composite, or combinations thereof. Additionally, a method for producing a 3D printed proppant is provided.

3D printed proppants and methods of making and use thereof

A process for designing a coated proppant particle for downhole transportation and placement. A carrier fluid may transport the coated proppant particle downhole. The process may include selecting a proppant particle material and a coating material. The process may also include selecting a target reduction in a settling velocity and determining a diameter of the coating material disposed on the proppant particle material based on the selected proppant particle material and the density of the coating material. The process for designing a coated proppant particle may include selecting a coating material thickness for coating on the proppant particle material and determining a coating material and design for coating on the proppant particle with the coating material thickness based on the selected proppant particle material and thickness of the coating material to achieve the target reduction in settling velocity.

Methods for designing coated proppant in low viscosity carrier fluid

Treating a sulfide scale includes contacting the sulfide scale with an oxidizing composition that includes a first oxidizer and a second oxidizer.

Treatment of sulfide scales

A method includes mixing seawater with a two-part additive system configured to precipitate sulfate from the seawater; removing the sulfate precipitates from the seawater; and delivering the seawater into an oilfield reservoir.
