A wellhead surface casing vent flow test identified shallow gas migration contained within the wellhead A-section of a soon to be decommissioned well.

An Australian Onshore Operator’s decision to exit upstream operations saw the need to plug and abandon 144 wells consisting of both vertical fracture stimulated and horizontal multi lateral well types.

An operator needed to reduce well rehabilitation liabilities. JJM personnel performed an options analysis to estimate the economic benefit of performing plug and abandonment works involving vertical conventional wells with alternate technologies

At the completion of the intended final injection and withdrawal cycle of an underground gas storage facility JJM personnel performed a fitness for service assessment to determine if further cycles could be completed with the facility

Following changes to state based legislation an Australian operator tasked JJM personnel to develop and then deploy a well integrity management system (WIMS).

JJM personnel were providing asset support in the form of production optimisation and reservoir surveillance for an operator. Routine well monitoring including the running of SGS and modelling of tubing inflow performance identified that liquid loading due to reduced reservoir pressures and increased condensate production would result in substantially reduced estimated ultlimate recover of gas from the well.

A multi discipline sub surface opportunity review of an operators field area was completed by JJM personnel.

The review and identified additional production optimisation and well stimulation techniques that could be applied to an existing play of low permeability sandstone reservoir.

A Queensland operator’s exploration work program required the drilling of a ~2800mMD exploration step out well.

JJM personnel were responsible for the design, tender and execution of the well delivery and subsequent initial completion in strict compliance with state codes of practice.

Due to high virgin methane content in a future long wall mining location, a coal mining company had a requirement to accelerate mine gas drainage operations beyond their usual underground drilling program with the use of oil and gas style directional drilling technology. The application of “surface to inseam” drilling enabled accelerated gas drainage of the long wall panel area ahead of mine development activities.
