Formation Damage

Integration of Core Flood and Geomechanics

Laboratory testing applied to the oil and gas industries has many objectives. Routine testing may be used to quality control products
and ensure they are within expectations. For example, crush testing for proppants or drilling mud rheologies. In more sophisticated
geomechanics testing, measurements are made to predict how rock will respond to changes in stress. Will the rock fail and, if so, will
the yielded material come to surface?

Fluids that we inject into reservoirs may also affect their geomechanical response. Acids may weaken the rock fabric. In water sensitive
formations, the salinity of the brine may impact on injectivity as well as rock strength and stiffness. In today’s increasingly complex high
value wells, focussing on both of these subject matters at the same time brings significant benefits to the industry.
