Technology Research and Development

In order to gain competitive edge in the expanding scene of worldwide E&P, the development of unique leading technologies and the strengthening of fundamental technologies for efficient project execution is a must. To this end, JAPEX Research Center is actively pursuing the development of IOR, shale resources, geomechanics and acidizing technologies, and is also striving to strengthen its expertise in the characterization and modeling of various type of reservoir rocks.

IOR (Improved Oil Recovery)

As a measure to maximize production from its fields, JAPEX employs IOR (Improved Oil Recovery) techniques such as gas injection and water injection in some of domestic fields, and steam-assisted gravity drainage (SAGD) in Canada. In addition, it is considering the application of more sophisticated IOR techniques to other existing fields.

Shale Oil & Gas Development Technology

Multi-stage hydraulic fracturing along a horizontal well has been established as the standard technique for shale development in North American fields. However, the characteristics of shale differ from field to field, and JAPEX is making efforts to develop technology that is suitable for specific shale properties.

Geomechanical Modeling

The importance of geomechanics in oil and gas development has greatly increased, especially for the development of unconventional reservoirs. JAPEX research includes the development of gemechanical modeling techniques for predicting mechanical deformation of reservoirs and surrounding formations resulting from fluid injection or production. Expectations are high that the integration of geomechanical modeling with reservoir monitoring techniquies will become a new reservoir surveillance method in the near future.

Reservoir Monitoring Technologies

JAPEX and its group companies (GSC, JGI, and GEOSYS) have been developing monitoring technologies for microseismicity and surface deformation, in order to evaluate mechanical deformation and failures in and around reservoirs due to field operations involving fluid injection and/or production for utilization in optimizing operations.

Geological Modeling of Carbonate Reservoirs

Since carbonate rocks are affected by sedimentation as well as diagenesis, their reservoir characteristics (such as rock property and distribution) are complicated. For the optimization of the exploration and development of carbonate reservoirs, JAPEX Research Center is engaged in the study of sedimentation, diagenesis and pore systems of carbonate rocks using various techniques including lithology and geochemistry.

Geological Modeling of Volcanic Rock Reservoirs

Volcanic rocks erupted undersea comprise the main hydrocarbon reservoirs in a majority of Japanese oil and gas fields. The understanding of three-dimensionally heterogeneous volcanic reservoirs is a crucial issue in reservoir evaluation, and JAPEX has successfully employed multiple-point geostatistics in the modelling of these volcanic rock reservoirs.

Reservoir Modeling of Oil Sands

Oil sands have been interpreted as a tidal-influenced meandering river deposits, which exhibit extremely heterogeneous lithology. Since this lithological heterogeneity can affect the oil production efficiency, it is important to understand and incorporate geological concepts such as depositional environments in the reservoir models, expressing the lithological heterogeneity. JAPEX employs geostatistics techniques to reflect geological concepts by “training images”, including complex patterns of lithological distribution in point-bar deposits.

Optimization of Acid Stimulation

The pores of the reservoir rocks can become plugged by drilling mud, minerals etc., causing the wells to become less or under-productive. In order to remove near-well damage, acid is pumped into the well and pores; this technology is called “acidizing”. JAPEX is conducting R&D to optimize the design of acidizing with the aim of increasing oil and gas recovery.
