1. A memory tool deployment method, comprising:
- fitting a landing assembly having a landing ring on an end of a pipe, the landing assembly defining at least one slot for communicating fluid around the landing ring;
deploying the pipe and the landing ring in a well;
connecting a memory tool to a wireline;
deploying the memory tool through the pipe in the well with the wireline;
landing the memory tool on the landing ring on the pipe by engaging a landing collar on the memory tool against the landing ring so that the memory tool extends exposed in the well beyond the end of the pipe;
releasing the memory tool from the wireline;
removing the wireline from the pipe; and
allowing fluid flow between an interior of the pipe and the well beyond the end of the pipe by diverting fluid communication around the engagement of the landing collar against the landing ring via the at least one slot defined in the landing assembly.

Abstract
Memory tool deployment method, system, and apparatus include a landing ring fit on a pipe deployed in a well. A drop-off tool has a landing collar and has a tool string with one or more memory tools. The drop-off tool is connected to a wireline and is deployed through the pipe in the well with the wireline. The drop-off tool is landed on the landing ring on the pipe so that the memory tools extend beyond the pipe. The wireline is released from the drop-off tool and is removed from the pipe so that logging operations can be performed. After logging, the wireline is redeployed in the pipe in the well and is reconnected to the drop-off tool to retrieve the memory tools from the pipe.

8. A memory tool deployment system, comprising:
-
a landing assembly deployable on an end of a pipe in a well and defining a passage having a landing ring, the landing assembly defining at least one slot for communicating fluid around the landing ring; a coupling member connectable to a coupling mechanism attached to a wireline deployable through the pipe; and a tool connected to the coupling member, the tool deployable with the wireline though the pipe and deployable at least partially through the passage in the landing assembly, the tool having a landing collar engageable with the landing ring and having a memory tool capable of extending exposed in the well beyond the landing ring and the end of the pipe, wherein the at least one slot in the landing assembly diverts fluid communication around the engagement of the landing collar with the landing ring and allows fluid flow between an interior of the pipe and the well beyond the end of the pipe. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A memory tool deployment apparatus comprising:
-
an insert disposable in a bore of a pipe in a well and defining an internal passage, the internal passage having a landing ring, the insert defining at least one slot for communicating fluid around the landing ring; an elongated body having first and second ends and deployable with a wireline through the bore of the pipe, the first end having a memory tool; a coupling member connected to the second end of the elongated body and connectable to a coupling mechanism attached to the wireline deployable through the bore of the pipe; and a landing collar positioned on the elongated body and engageable with the landing ring of the insert, wherein the at least one slot in the insert diverts fluid communication around the engagement of the landing collar with the landing ring and allows fluid flow between the bore of the pipe and the well beyond an end of the pipe. - View Dependent Claims (19, 20, 21, 22, 23)

24. A memory tool deployment system, comprising:
-
means for deploying a memory tool with a wireline through a pipe in a well; means for passing the memory tool through a landing ring on an end of the pipe; means for engaging the landing ring to support the memory tool in the well beyond an end of the pipe; means for releasing the memory tool from the wireline; and means on the landing ring for diverting fluid flow through at least one slot communicating fluid around the engagement of the memory tool with the landing ring to allow fluid communication between an interior of the pipe and the well beyond the end of the pipe. - View Dependent Claims (25, 26, 27, 28)
