Drillability and Completion Selection in Mature Fields with Depleted Reservoirs Interbedded with Weaker Formations

Description Text

Drilling, completion and production from wells passing through depleted reservoirs and interbedded weak formations can be a challenge. Pressure depletion in reservoir sections causes a decrease in the fracture gradient. Interbedded non reservoir sections, however, require a higher hole pressure to maintain the wellbore stability while drilling and during life of the with open hole completion.
A workflow for building and updating geomechanical model is presented with applications for wellbore stability analysis, sanding evaluation and selection of optimum completion for a number of wells in two fields.

Abbas Khaksar: is a Global Geomechanics Advisor and subject matter expert in solids production prediction and management with Baker Hughes-GMI Geomechanics Services.  Abbas holds a BSc in mining engineering from Tehran University (1989), a MSc in petroleum geology and geophysics (1994) and a PhD in rock physics (1998) from the University of Adelaide. From 1989 to 1992 he worked for Iran geological survey as a field engineer, in 1999–2000 was a post­doctoral researcher at the University of Adelaide studying pore pressure prediction and CO2 sequestration then for Geomechanics International (GMI)-Perth from 2000 to 2005 as a geomechanics specialist and later manager-consulting services in Asia-Pacific. He joined Helix RDS in 2005 as a senior then principal geomechanics specialist and worked in Perth and London until 2009 when Baker Hughes acquired Helix RDS.  In 2010-2011 he was Asia Pacific Geomechanics team leader for Baker Hughes-Reservoir Development Services (RDS).  He is a member of SPE, FesAus and American Rock Mechanics Association (ARMA).
