Cased Hole Wireline Logging RFQ — Cement Bond, CCL, Gamma Ray, and Memory PL Toolstring Fields
Buyers search cased hole wireline logging, cased hole wireline, or cased hole logging services when a cased well needs a toolstring quote — and the request often collapses to "cased-hole logging, please quote." That hides the decisions that drive fit: evaluation objectives, depth correlation, Ultrawire surface readout vs memory, and which published tools belong on the BOM.
This page is not a rewrite of the open-hole vs cased-hole logging buyer guide. Use that page for borehole-state choice (open vs cased). Use the soft what's the difference between open-hole and cased-hole logging post only as a primer. This page turns a cased-hole wireline program into RFQ fields that feed live product pages — Cement Bond Tool, Casing Collar Locator, Production Gamma Ray, Memory Production Logging — and request a quote.
Start with the logging program, not with a tool label
Name the cased-hole objectives before you ask for a string:
| Program objective | What the RFQ must answer |
|---|---|
| Cement bond integrity | Evaluate casing / cement / formation acoustic amplitude (higher received amplitude = poorer bond per live Cement Bond Tool page)? |
| Depth correlation | Collar / perforation depth control via CCL — and/or GR depth correlation? |
| Production gamma | Lithology ID, radioactive scale, tracer, or gravel-pack monitoring (PGR apps as published)? |
| Production / injection profiling | Memory PL path (slickline or coiled tubing; PL and inspection tools as published)? |
| Saturation-behind-pipe / pulsed neutron | Out of scope — no dedicated pulsed-neutron PDP cited; confirm availability with CNPS separately if needed. Do not invent specs. |
Keep open-hole petrophysics suites and unlisted pulsed-neutron claims off this RFQ. Quote only tools that map to live CNPS pages.
Product path — map to published cased-hole tool pages
Four live product pages own the hard figures. Use only published values; ignore conflicting sidebar weight widgets.
0 — cased-hole cementing logging for bond integrity. Design: one transmitter, two receivers (3 ft and 5 ft spacing). Can combine with analog GR and CCL for depth correction. Features as published: cementing evaluation; selectable gain; H2S resistant. Confirm casing size / rating / well medium / H2S; GR/CCL combo; telemetry or memory mode.
0 responds to metal volume changes (collars, perforations). Power / control via system controller (e.g. XTU). Apps: depth control in casing and tubing; location of severe casing or tubing damage; confirmation of perforation depths / intervals. Options: UW or Mbus; slickline memory or surface readout (with telemetry controller); simultaneous with other CNPS tools; Sondex compatible. Body-table specs: telemetry XTU or UMT; 105 MPa; 177 °C; 18 VDC; <16 mA; length 470 mm; measure point 165 mm; diameter 38 mm; weight 5.1 kg; end thread 13/16″ 12 UN2A. Soft context: CCL key to precision.
0 — 4″ NaI scintillation crystal, photomultiplier, 1.6 kV HV supply; cased-hole production logging. Apps: lithology identification; depth correlation; radioactive scale; tracer monitoring; gravel-pack monitoring (with gamma source). Options: UW or Mbus; slickline memory or SRO. Specs: 105 MPa; 177 °C; threshold 20 keV; sensitivity 1 count/API; accuracy <10%; 18 VDC; <20 mA; length 586 mm; measure point 134 mm; diameter 43 mm; weight 4.3 kg. Sister gamma ray tool lists alternate sizes 1 3/8 in (35 mm) / 1 11/16 in (43 mm) and 350 °F / 15 kpsi — cite as on-page variants and confirm model.
0 — Standard Memory or Ultrawire; slickline or coiled tubing; PL and inspection tools. MEMLOG software; MIP interface; lithium battery MBH. Apps: slickline & CT PL; production / injection well profiling; multifinger imaging tool surveys. Specs: 105 MPa; 177 °C; 13.5–20 VDC; sample rates 0.1 / 0.2 / 0.5 / 1.0 s then whole seconds; 32 Mb (64 Mb for MIT); length 505 mm; diameter 43 mm; weight 4.8 kg; end thread 13/16″ 12 UN2A.
Path: objectives → live PDP tools → UW vs Mbus / slickline memory vs SRO → published ratings → GR/CCL combo → pulsed neutron ask CNPS (no invented PDP).

- Depth correlation — CCL and/or PGR.
- Memory PL — Memory Production Logging for slickline or CT production / injection profiling.
- Borehole-state choice — open-hole vs cased-hole logging buyer guide (#3) if still choosing open vs cased; this page assumes cased-hole wireline toolstring RFQ.

No invented pulsed-neutron specs, prices, plants, case studies, SKUs, or certificate seals. No sidebar weight widgets that conflict with tool tables.
Cased hole wireline logging RFQ checklist

- Commercial — quantity, destination, need-by date; send via request a quote.
FAQ
Is this the same as the open-hole vs cased-hole buyer guide? No. #3 compares borehole states. This page RFQs a cased-hole wireline toolstring (cement bond + CCL + PGR + memory PL).
Do you publish pulsed-neutron / PNL specs here? No dedicated pulsed-neutron PDP is cited. If saturation-behind-pipe is an objective, ask CNPS separately — do not invent figures.
UW or memory? CCL and PGR list Ultrawire or Memory toolbus, and slickline memory or surface readout. Memory PL lists Standard Memory or Ultrawire, slickline or coiled tubing. State the mode on the RFQ.
Which weight for CCL? Cite the body table: 5.1 kg. Do not use a conflicting sidebar widget.

A useful request fits on one page: objectives, casing / H2S, conveyance and bus, cement bond config, CCL / PGR / memory PL lines with published ratings, any out-of-scope ask to confirm, and commercial fields. Confirm figures only against the live product pages.
