Multi-pressure toe valve

A toe valve comprising:

• a. a top sub:
• b. an outer tubular member including a plurality of outer flow ports, a first end of the outer tubular member being fixed to the top sub;
• b. an inner tubular member positioned at least partially within the outer tubular member and forming an annular space therebetween, the inner tubular member (ii including a central flow passage and a plurality of inner flow ports, and (ii) including a first end fixed to the top sub such that the inner tubular member cannot move axially with respect to the top sub;
• c. a port sleeve positioned in the annular space to selectively block communication between the outer flow ports and the inner flow ports;
• d. an indexing mechanism positioned at least partially within the annular space, the indexing mechanism comprising an indexing groove formed in a zigzag pattern and an indexing member traveling in the indexing groove;
• e. a flow path allowing fluid pressure from the central passage to act against a first side of the indexing mechanism;
• f. a biasing device acting on a second side of the indexing mechanism;
• g. wherein the indexing mechanism is configured to allow communication between the central flow passage and the annular space after a plurality of forward/rearward movements of the indexing mechanism;
• and
• h. wherein the port sleeve is configured to shift and allow communication between the outer flow port and the central passage when acted upon by increasing fluid pressure in the annular space.

A downhole valve comprising:

• a. an outer tubular member including at least one outer flow port;
• b. an inner tubular member positioned at least partially within the outer tubular member and forming an annular space therebetween, the inner tubular member including a central flow passage;
• c. a port sleeve positioned to selectively block communication between the outer flow port and the central flow passage;
• d. an indexing assembly positioned at least partially within the annular space, the indexing assembly comprising (i) an indexing surface formed in a generally forward and rearward direction;
• (ii) an indexing member traveling to engage the indexing surface and to generate rotative motion when engaging the indexing surface, wherein fluid pressure from the central passage moves the indexing assembly in one direction, a biasing device moves the indexing assembly in an opposing direction, and the indexing assembly is configured to allow communication between the central flow passage and the annular space after a plurality of forward/rearward movements of the indexing assembly;
• and
• e. wherein the port sleeve is configured to shift and allow communication between the outer flow port and the central passage when acted upon by increasing fluid pressure in the annular space.
