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.

Abstract: A method and apparatus for actuating a downhole tool at a desired location. A reciprocating hydraulic slickline pump with a locator is provided. The pump comprises a pump member. The pump member is reciprocated axially by slickline in order to form an upstroke and downstroke. The pump is configured such that it pressurizes fluid within a workstring assembly during the pump's downstroke.

Abstract: Methods and apparatus for logging a wellbore and determining a presence or absence of a hydrocarbon bearing formation are disclosed. A sonde includes at least two gamma radiation detectors that are utilized for chlorine logging and lifetime logging in combination. Additionally, two detectors of the sonde are spaced axially from each other at different distances from the source to enable determination and compensation for various other parameters such as porosity and water flow velocity. Appropriate gating of the detectors enables sensing total counts of radiation emitted from adjacent formations and sensing of specific energy ranges of radiation when the formation is bombarded with energy. Signals from the lifetime logging enable adjustment of the chlorine logging for a borehole effect and background radiation. The detectors can include a sheath of a high capture cross-section material that interacts with neutrons to produce gamma radiation to shield the detectors.
