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.
