Embodiments presented provide for a multi-flowline control system and methods for dynamically switching fluid flow in downhole tools. The method may include operating the downhole tool in a first valve configuration, the downhole tool configured to sample fluid from a geological stratum, sending an actuation signal to the first valve configuration, receiving the actuation signal at the first valve configuration, altering the first valve configuration to a second valve configuration, where the first valve configuration allows for sampling of fluids from the geological stratum outside the downhole tool to the second valve configuration and where the downhole tool is configured to operate in a closed-loop configuration wherein sampling of fluids from the geological stratum is not possible, and circulating fluids within the closed loop configuration.
A method for dynamically switching fluid flow in a downhole tool, comprising:
The method according to claim 6, wherein the circulating of the fluids in the closed loop configuration is through a pump.
The method according to claim 6, wherein the circulating of the fluids is at a velocity greater than a sampling velocity within the downhole tool.
The method according to claim 6, wherein during the circulating of the fluids, materials on a sensor arrangement in the downhole tool are dislodged.
The method according to claim 6, further comprising:
An adapter, comprising:
The adapter according to claim 11, wherein the second end is configured with threads.
The adapter according to claim 11, wherein the first end is configured with a mechanical connection.
A method for dynamically switching fluid flow in a downhole tool, comprising:
The method according to claim 14, wherein the circulating of fluids within the closed-loop configurations dislodges accumulated debris within the downhole tool.
The method according to claim 14, wherein the circulating of the fluids within the closed-loop configuration originates from a fluid source carried within the tool from the up-hole environment.
The method according to claim 14, wherein the circulating of the fluids within the closed-loop configuration includes fluids passing through at least one of a sensor array and a flow routing plug.
The method according to claim 14, wherein the circulating of the fluids is accomplished through at least one pump.
The method according to claim 18, wherein the at least one pump is controlled such that different velocities of fluid, within the closed-loop configuration are achieved.
