Abstract

One of the most common geomechanics problems is reservoir compaction and its associated land surface subsidence. This problem is complex and the atrected geomechanics parameters vary across the underground formation- Subsidence cuurcs major environmental concerns, leading to risk of flooding in land operations or pladorm safety in offshore production. The same problon in hydrocarbon production and underground water rernoval has significant impact to both the exploitation sche,me and the surface environments. Previous researches focused on examining the displacement of the subsided area and its stress field by assuming the geomechanics properties of the reservoir and its surrounding to be homoge,lreous. Howev€r, geomechanical medium is typically corrplor urd inhomogeneorui. Smre other reserches assume variatim of one parameter to be independent of the rest of other parameters. This confines the investigation by looking at specific geomechanics parameters in certain region oly. Consequently, the parameters cannot be de-risked in a holistic mann€r with 6ese assumptions. This project intends to propose a geomechanical de-risking worldow that utilizes components such experimental design, tornado chart, Multi-Variate Regression (MVR), and First Order Reliability Method (FORM). The Geomechanics tool will be treated as 'black box' engine that generate desired resporuies. m
