The invention is a petroleum well downhole logging tool (0) comprising - a wireline telemetry controller unit (6) comprising - a downhole modem (61 ) for transmitting data at a first bitrate uplink on a wireline (8) to a surface telemetry unit (106) connected to a surface read-out unit (SRO) with a memory (123)),a server toolbus controller (62) connected between said downhole modem (61 ) and an internal tool databus (7) operating at a second bitrate (r2) higher than the first bitrate; - one or more logging tools (4) each with sensors (40a, 40b, 40c,...), each with a client toolbus controller (42) connected on said tool databus (7), said downhole logging tool (0) further comprising - a memory tool unit (2) with a memory section (21 ) with relatively high IO speed and capacity and connected to said internal tool databus (7) via a memory tool client toolbus controller (42m) connected to said tool databus (7) and arranged for communicating with said server toolbus controller (62), said memory tool (2) further provided with - an internal local high speed data bus (3) operating at a third bitrate (r3) higher than said second bitrate (r2), to - a high-resolution logging tool (1) with one or more sensors (1 s) which provides high- resolution data (11), - said memory tool (2) arranged for transmitting a part (11s) of said high-resolution data (11) via said internal tool databus (7) online to said server toolbus controller (62) during logging, and - for uploading more of or all of said high-resolution data (11) via said server toolbus controller (62) to said surface telemetry unit (106) and said surface read-out unit (SRO). |
