Anticipate reservoir compaction

The impact of reservoir compaction on field development is best examined early in the life of the field when there is opportunity for proactive planning.

Schlumberger Geomechanics experts use a workflow based on developing a reservoir mechanical earth model (MEM) to predict reservoir compaction from pressure depletion and its associated impact on casing deformation and surface subsidence. 

Using an MEM to capture drilling and production data

The use of an MEM enables the capture of all information relating to the geomechanics of drilling and production, such as the in situ stresses, rock failure mechanisms, rock mechanical parameters, geological structure, and stratigraphy. The model can then be used to identify geomechanics problems and draw up contingency plans for handling these problems before a well is drilled or the field is put on production.

Geomechanical hot spots—where reservoir compaction is predicted to be greatest—are identified, allowing production strategy to be optimized. Several possible modes of production-induced casing failure are examined, and the likelihood of casing failure is assessed, facilitating development of strategies for either avoiding such risks or reducing their impact.

Subsidence at surface is also estimated for the life of the field to assist with the design or placement of surface facilities or possible disruption to existing surface infrastructure.
