Well Plug & Abandonment using HWU

The Platform was located in the Dutch North Sea. Due to reservoir depletion, production was shut down and the gas processing facilities were removed. Most wells were drilled in the period from 1981 to 1989 with well depths ranging from 1740 to 4300 m. The objective was to Plug & Abandon (P&A) 11 wells and […]

Rig-less abandonment

The platform was located on an old depleted oil field in the Dutch Continental Shelf. Oil production had ceased. The condition of the platform was such that the owner decided to abandon the wells and to remove the platform. Hydraulic workover was identified as the most efficient way to cut the casings and conductor of […]

Onshore Re-Abandonment

The well was drilled in 1996 to a depth of 3990m and was plugged with 5 cement plugs in the same year. In the years after surface pressure build up was detected and the decision was made to re-abandon the well. The objective was to find the leak path and to re-abandon this well. Works […]

Offshore Fishing

/ /
The platform was located on an Oil Producing Field in the Mediterranean off the coast of Sicily. The wells were completed in the mid 1980´s to produce heavy 15.5 API oil. Over the course of thirty years the integrity of these wells had suffered, thus a workover campaign utilising HWO was initiated. The platform previously […]

Coil Tubing Recovery

/ / /
The platform was located on a Large Gas Producing Field in the Central North Sea. The Wells were beginning to water out and in an attempt to increase production the decision was made to run Coil Tubing Velocity Strings. During the first string installation a runaway occurred which resulted in the shear seals being closed […]

Four existing multi-lateral horizontal gas wells located in the Southern North Sea were initially completed barefoot but production eventually ceased due to blockage of the production conduit by reservoir solids (sand and rocks). To mitigate this problem, 2-7/8” pre-drilled liner pipe made up in lengths of up to 200m was to be deployed on wireline […]

Live well Coiled Tubing Recovery

/ / /
This gas injector/producer well was drilled in 2014 to a depth of 2635 mAH. After the well was completed and tested, coiled tubing was used to retrieve a 5.75” RPT standing valve installed in the packer tailpipe. Pressure differential over the valve was equalized using nitrogen. Coiled tubing was not able to free the valve. […]

Offshore P&A – HWU and Liftboat

The platform is located in the German part of the North Sea in shallow water. The platform supports a single 3200m deep gas production well which was drilled and completed in 1991. The objective was to Plug & Abandon this single gas production well and to remove the surface casing, conductor and wellhead.


The well was drilled in 2012 to a depth of 2635m AH and was found dry. The 13-3/8” and 9-5/8” casing-shoes were set at 564m and 1295m respectively. The well was permanently abandoned by means of 5 cement plugs. The 9-5/8” production casing was cut and retrieved from 600m creating a uncased hole section of […]
