Fish through filter device

A method comprising:

• providing a filter device down a borehole as part of a drill string, wherein the filter device includes a valve in a closed position such that it obstructs an internal bore of the filter device, and an inner filter axially positioned within an outer filter such that an annular space is formed between the inner filter and the outer filter, the inner filter defining in part the internal bore;
• providing drilling fluid to the drill string;
• filtering a first portion of drilling fluid through the outer filter when the valve is in the closed position;
• applying force to the valve in order to open the valve such that the internal bore is unobstructed;
• and
• passing a wireline through the filter device via the unobstructed internal bore.

A system comprising:

• a drill string including a filter device deployed into a borehole, wherein the filter device comprises
• an outer filter;
• an inner filter axially positioned within the outer filter;
• an internal bore defined in part by the inner filter;
• and
• a valve operably connected to the inner filter and configured to regulate passage of drilling fluid through the internal bore,
• wherein the internal bore is obstructed when the valve is in a closed position,
• wherein the internal bore is unobstructed when the valve is in an open position, and
• wherein the filter device is configured to filter a first portion of drilling fluid through the outer filter when the valve is in the closed position;
• and
• a cable-type device configured to exert a sufficient force upon the valve such that it opens to allow the cable-type device to enter the unobstructed internal bore.
