Schlumberger Dhahran Carbonate Research Center

The Schlumberger Dhahran Carbonate Research Center (SDCR) is located in the eastern province of Kingdom of Saudi Arabia, close to King Fahd University for Petroleum and Minerals. Inaugurated in March 2006, the center currently has two main programs: Geology and Rock Physics (GRP) and Production Completion and Recovery (PCR). SDCR plays a central role in the collaboration of major clients in the Middle East with Schlumberger operations, Segments, and technology centers.

Geology and Rock Physics

GRP focuses on the petrophysical evaluation of carbonates, including oil viscosity, fluids saturation, pore-size distribution and wettability characteristics, permeability, rock texture, and reservoir rock type. Multiple-physics measurements conducted in the laboratory on cores involve nuclear magnetic resonance (NMR), dielectric, resistivity, and acoustics. Digital coring, fluid flow through micromodels of reservoir rocks, and core flooding are employed to analyze the reservoir properties of relative permeability and recovery factor.

Another area of research is focused on deep-reading measurements, which include cross-well electromagnetic imaging for locating unswept hydrocarbons in reservoirs and borehole gravity for fluid front monitoring in reservoirs undergoing either gas or water injection.

Production Completion and Recovery

The PCR group investigates the physical chemistry of interactions in carbonate rocks from nonreactive through reactive fluids, with the impact of carbonate rock type forming the core of PCR activity.

  • The Production group is developing new knowledge and technologies for stimulating oil and gas well productivity in carbonate reservoirs by injecting reactive fluid into the reservoir to either dissolve or fracture the rock. Efforts include improving the understanding of reaction kinetics via enhanced thermodynamic modeling, generating new data from fluid-rock interaction and core flooding experiments at reservoir conditions, and investigating the effects of geomechanics and rock mechanics on hydraulic fracturing stimulation treatments in carbonate wellbores.
  • The Recovery group uses advanced experimental measurements and molecular modeling to advance understanding and knowledge of the physical chemistry of the interaction of reservoir fluids, brines, and rocks to better design and monitor the recovery process in carbonate formations.

The well construction aspects of advanced completions are addressed through field deployments and qualifying. Examples include the development of multiple fracture stimulation treatments in openhole horizontal wells and completion technologies that enable lifelong monitoring and control of wells with enhanced reservoir contact.
