General Wireline Operations


One of the most common intervention technics in use. Visit this page to view basic good practices & documents to help plan & execute your operation successfully.


Gas Lift Valve Change-Out Operations


Gas lift valve change-out operations can be tricky & can easily overrun on time &cost. Visit this page to access basic advice, information & documents to help plan & execute your operation as effectively & efficiently as possible.


Coiled Tubing Operations


Coiled tubing operations involve the use of a lot of mechanical & hydraulic equipment, if poorly maintained or selected without correct focus on the specific requirements of the job in question, considerable downtime can be encountered.

Pre-mobilisation checks, by someone familiar with the overall project, can help to highlight many of the issues that have the potential to cause downtime, before the equipment mobilises.

Visit this page to view coiled tubing information & a sample checklist that can be used during pre-mobilisation checks.


Completions Operations


Many issues encountered when installing a completion are as a resulty of errors, miss-communication or confusing at the time the completion assemblies were being made up onshore.

Visit this page to view a sample checklist & Completions information that can be used during make up & pre-mobilisation. The information recorded can be used to confirm the assemblies are as requested before they are shipped.

Perforation Operations


The make up & shipping of perforating guns is a strictly controlled process & thus errors are relatively uncommon, however, it is a very good practice to confirm the guns are set up as required with as much detail as possible, before they are shipped.

Visit this page to view a sample checklist & perforating information that can be used during make up & pre-mobilisation.

Pumping Operations


As with coiled tubing, pumping & stimulation operations involve the use of a lot of mechanical & hydraulic equipment, if poorly maintained or selected without correct focus on the specific requirements of the job in question, considerable downtime can be encountered.

Visit this page to view a sample checklist & pumping services information that can be used during make up & pre-mobilisation.

Welltest Operations


Well testing is one of the most hazardous operations a drilling rig will undertake. The very nature of well testing, is to offload the fluid that the rig has worked so hard to maintain well control with, & then bring the hydrocarbons around the rig to process & flare it.

Visit this page to view a sample checklist & well testing information that can be used for planning & pre-mobilisation.

Tree & Wellhead Operations


While Xmas tree & Wellhead equipment are an intrinsic component of every well, they are often non-routine or awkward lifts due to weight, centres of gravity, available space or clash points at the installation site. Xmas tree & wellhead equipment is usually not shipped with a backup, damage can be costly in both time & money. It is a good practice to gather information &/or manufacture installation equipment that can be supplied to the rig in advance of shipping.
