Stress Testing – Measuring Insitu Stress 
Speaker: Emilie Peyret (Schlumberger)

Emilie Peyret is a Reservoir Domain Champion at Schlumberger, with a diverse experience in wireline formation testing and sampling and stress testing. She has worked in Kuwait, Mexico, Central and West Africa, and Europe.

Abstract : Stress testing or micro hydraulic fracturing measures minimum horizontal stress insitu at a specific depth. A direct measurement of the minimum horizontal stress of the cap rock relates directly to the maximum safe injection pressure that can be used in the reservoir layers below said cap rock or it can directly impact production, and/or the amount of fluid that can be stored in an underground storage. This measurement is a calibration point for the geomechanical models, reducing uncertainty that exists, and derisking the reservoirs and projects.

Characterizing the current state of stresses with a formation tester over a caprock and a reservoir or even over an entire lithological column is becoming more in demand with the increase in storage projects and the energy transition underway. The complexity of the formations to be tested, from deeper, harder rocks, to tighter more impermeable formations such as caprocks means that new workflows need to be built to maximize data accuracy as well as efficiency.

Current day stress testing capabilities and improvements in the hardware will be discussed as well as different methods available to evaluate tight formations in order to estimate closure stress.

Speaker: Olav-Magnar Nes, Aker BP


Olav-Magnar Nes
is Senior Drilling Engineer Rock Mechanics at AkerBP in Trondheim. He has a PhD in solid state physics from the Norwegian Institute of Science and Technology in Trondheim, NTH (now NTNU), in 1992. He joined SINTEF Petroleum Research in 1992 and AkerBP in 2013. His general interests are within rock mechanics and rock physics. He has extensive experience with in-situ stress testing and has been actively involved in development and improvement of methodologies for acquiring microfrac stress data in tight formations.
