Drilling through depleted zones is fundamental to most mature reservoirs worldwide. Mature fields play a crucial role in global oil and gas production and drilling have become an issue as they are probed to sever losses due to sever depletion from years of production. Sometime this well is deemed not economical due to the associated risk in well construction, completion and workover within low pressure and sometimes is a combination of low- and high-pressure environment in a single section become more challenging.

Designing of fluids in mature fields, where wells have been exploited extensively, novel drilling fluids are used to target un-depleted hydrocarbon layers below the depleted ones with unique background Lost Circulation Material while drilling. Advance simulation predicting fracture across the depleted reservoir play a big role to minimise the lost time from loss circulation. Customised fluid compositions are essential to minimise formation damage as well as getting to the targeted reservoir safely and optimised drilling parameters.

There are a variety of damage mechanisms as wells are drilled and produced.  There are Natural Damages which include fines migration, swelling clays, water-formed scales, organic deposits (wax or asphaltenes), emulsion blockage / change of wettability, water production, sand production. There are also Induced Damages which include drilling fluids or secondary and tertiary efforts by either chemical reactions or interaction of entrained solids, plugging by entrained particles such as solids or polymers in injected fluids, wettability changes caused by drilling, acid stimulation, or injected fluids, e.g., emulsion blockage.

This session provides an opportunity to show various chemical or mechanical solutions that have been used or present newer technology used to remediate these common problems. Is there a new less damaging mud system or additive in the drilling fluid to protect the reservoirs. Is there a new and improved acid system?

Drilling Waste management and environmental discharge regulation considerations are crucial aspects that must be considered in planning to drill a well or campaign in any project.

This technical session aims to provide the participants with a review of the current methods of drilling waste managed and disposed of. As we all know environmental discharge regulation can differ depending on countries, offshore/onshore and regions. The sustainable practices and strict environmental regulations play a pivotal role.

The overview focusing on new technologies, best practices, and regulations in waste management and environmental protection will be shared from past experience and current practices from different country operations.  We believe we can build a very productive session and share the knowledge to be adapted to other operations areas or countries/regions, plus more importantly more countries are moving and in discussion on the emerging trend towards zero-discharge regulations, where new technologies like reuse & recycling systems and advanced treatment methods are employed to minimize or eliminate discharge.

Discussions will include case studies and implementation of thermal treatment solutions, environmentally sustainable disposal methods and new/best techniques to tackle environmental regulations when drilling the well.
