Abstract
An apparatus comprises one or more solids separators to be positioned downhole in a well formed in a subsurface formation, wherein each of the one or more solids separators are configured to receive a fluid from the subsurface formation and separate out sediment from the fluid, wherein the sediment is transported after separation to a destination location.
Claims40
An apparatus comprising:
- one or more solids separators positioned in a downhole oil-water separation system in a well formed in a subsurface formation, wherein the downhole oil-water separation system is configured to receive a fluid from the subsurface formation, and wherein each of the one or more solids separators are configured to separate out sediment from the fluid, and wherein the sediment is transported after separation to a destination location, and wherein the downhole oil-water separation system is configured to remain in position in the well when the one or more solids separators are retrieved.
A system comprising:
- a downhole oil-water separation system to be positioned in a well formed in a subsurface formation, wherein the downhole oil-water separation system is configured to receive a fluid from the subsurface formation;
- and
- one or more solids separators to be positioned in the downhole oil-water separation system, wherein the one or more solids separators are configured to separate out sediment from the fluid, and wherein the downhole oil-water separation system is configured to remain in position in the well when the one or more solids separators are retrieved.
A method comprising:
- performing a downhole separation of at least one of fluids or solids downhole in a well that is formed in a subsurface formation, the performing comprising, introducing a formation fluid from the subsurface formation into the well,
- separating the formation fluid into a production fluid and a nonproduction fluid via a downhole oil-water separation system positioned in the well and configured to receive the formation fluid,
- separating sediment from the nonproduction fluid via one or more solids separators positioned in the downhole oil-water separation system, wherein the sediment discharged from the one or more solids separators is temporarily stored in one or more solids accumulators while the downhole oil-water separation system receives the formation fluid, and
- transporting the sediment to a destination location.
