Daya Maxflo is providing GAIA’s technology in Malaysia and Indonesia.


GCPS is a result of many years of intensive “field based” R&D by Gaia. The system is designed to facilitate safe and efficient wireline conveyance in tortuous wellbores which might otherwise result in cancelled surveys, cable fishing, pipe-conveyed logging or additional LWD runs. GCPS is an integrated service, combining Gaia’s proprietary conveyance software “Wire-Pro” (linked to our global sticking database), wireline standoff hardware (WLSOs) and petrophysical expertise. GCPS may (or may not) include a plan to deploy WLSOs – depending on the risk profile of the well. To date GCPS has de-risked over 55 critical wireline runs on 30 high profile wells worldwide and saved upwards of $15-25M in NPT: ROI varies from 8:1 to 50:1 depending on the rig-rate and well depth. (Cost of missed data and cancelled sampling points without GCPS not included.

GAIA Cable Protection System [GCPS] Animation

  • State of the art modelling package (conveyance & sticking)
  • Systematic engineering approach to assess conveyance risks
  • Benchmarking future sticking risk against offset wells
  • Monitoring sticking risk with time-depth
  • Optimization of job plans to minimise sticking risks
  • WLSO deployment planning and operating guidelines
  • Development of regional or project sticking databases


The demand for GCPS is influenced by three things:

a) The logging environment (wellbore trajectory & BHA, geology & mud, rock mechanics & pore pressures).

b) The wireline conveyance system, and any limitations it may possess (e.g. limited pull on land as opposed to high tension logging systems offshore).

c) The client’s desire to minimize their operational & financial risks. The baseline requirement for cable sticking risk is a tortuous open hole section: a distinct change in hole deviation or azimuth from the Casing Shoe to TD. A deviated but straight open-hole section does not generally create sticking risk unless there is concern over differential sticking over upper (exposed) sands when deep sampling.

  • Any well with offset cable sticking experience
  • Tortuous wells with soft formations over the build/drop zones
  • Moderately tortuous wells with permeable sands (esp. depleted)
  • Wells with long OH sections (build/drop outside the CSG shoe)
  • Deepwater jobs & soft formations: risk of pulling too much
  • Land jobs: risk of not pulling enough

GAIA Cable Fished


Wire-Pro is Gaia’s proprietary conveyance software, with a special focus on open hole operations and sticking risks (tools and cable). Wire-Pro facilitates the benchmarking of cable sticking risk at the pre-spud stage and also during drilling (with time-depth). Wire-Pro determines whether wireline standoffs (WLSOs) may be required for a run, how many are needed, and where they should be deployed on the cable. It also assesses the degree of sticking linkage between tools and cable, whereby overpulls to free stuck tools may induce cable sticking, due to higher applied thrusts when cycling the line. Wire-Pro identifies risks that other conveyance packages cannot, due to its advanced algorithms that integrate cable forces, pore pressures, and available LAS data.

  • Conventional modelling outputs for independent conveyance QA
  • Well characterisation and risk profiling by tortuosity
  • Integration of mud-log and LAS data to aid well visualisation
  • Inclusion of pore pressures for differential sticking
  • Cable thrust visualisation and 3D contacts along the wellbore
  • “Lookahead” feature for tool sticking risk vs. depth
  • WLSO deployment planning (zones, depths, quantity)

GAIA Wire Pro cable sticking risk software


provide a precision mechanical intervention down-hole: dispersing cable thrusts, minimizing cable contact area, and suspending the cable above pre-cut slots. WLSOs are deployed in arrays (typically @ 40-110 feet space-out) to cover specific sticky zones in the wellbore. The WLSO O.D. is selected according to the pipe size and fishing gear on the rig. The minimum number of WLSOs deployed to date is 5 and the maximum is 60. (The average number is 33 per run.) The installation time is less than 2 minutes per WLSO, including winch driving between WLSO stop-depths.

  • Made in UK to British Standards, within an ISO9001 QMS
  • Detailed QA & conformance reports supplied
  • Available in a range of sizes: from 2.15″ to 2.95″
  • Cable insert packs supplied according to requirements
  • Custom WLSOs available on request (e.g. H2S or special size)
  • Rollered CH version available to reduce cable drag with tractor

GAIA Wireline Standoff WLSO


WXSO “XRAY” is the world’s first cable mounted acquisition package. WXSO records high resolution data about the wellbore environment and cable dynamics during a logging run.

  • Cable contact log for improved WLSO deployment rationales & planning efficiency
  • Early stage keyseating i.d. (cable stick-slip during continuous passes)
  • Independent wireline jar firing and re-cocking records
  • Independent record of all sticking events (e.g. cable or upper tool-string?)
  • Loss & influx zone identification, and wellbore transients during clean-up & sampling
  • Cable torque log for stranding risk analysis
  • Mud integrity log and slump identification (wrt conveyance & sticking risks)
  • Buoyancy corrected tension modelling (better benchmarking)
  • Continuous creep log for improved depth control and survey efficiency for formation testers
  • Mercury-free continuous temperature log
  • Cased hole contact log for predicting wireline wear zones
