Wellbore Stability

Rock Fluid Imaging Lab provides integrated geomechanical analysis considering core geomechanics laboratory testing, well data (pressure data, mud pressure, petrophysics & image log) and field data for preventing Wellbore Instability during drilling and sand production.

Time Dependent Analysis for Wellbore Stability in Shale

Rock Fluid Imaging Lab provides laboratory test and analysis for maintaining well stability is an important problem in the oil and gas industry. After drilling, drilling fluids and their filtrates enter the formation. Water-sensitive shale formations can be hydrated by the incoming drilling fluids, resulting in expansion. In addition, the formation strength gradually decreases with increasing immersion time.

Therefore, it is necessary to implement a special strategy to predict the maximum time that must not be exceeded to prevent well bore collapse.

Wellbore Stability due to CO2 Injection in Carbonate

Rock Fluid Imaging Lab provides integrated geomechanical analysis considering core geomechanics laboratory testing, CO2 injection for preventing Wellbore Instability during drilling and sand production.

Pore Pressure Prediction

Rock Fluid Imaging Lab provides integrated geomechanical analysis considering rock physics, lithofacies, temperature, stress, strain, and reservoir parameter (porosity, lithofacies) for producing accurate subsurface information such as pore pressure distribution and also fault sealing analysis.

Many hydrocarbon reservoir in Southeast Asia have been dismembered by faults, and its become critical issue whether these faults are barriers or conduits for hydrocarbon.

Pore pressure prediction are useful for :

• Fault sealing and leaking analysis
• Reservoir compartment analysis
• Pre-drill pore pressure prediction for safe and economic drilling

Subsidence Analysis

Rock Fluid Imaging Lab provides an advanced analysis of Geomechanics Parameters that influence the subsidence phenomena due to the production. This integrated geomechanical analysis considering geomechanic core test (Young Modulus, Poisson's Ratio, Internal friction Coefficient, Cohesion, biot's coefficient and also bulk, matrix and fluid volume compressibility), stress state (overburden stress, maximum horizontal stress, minimum horizontal stress, pore pressure, hydrostatic pressure), strain, and reservoir parameter (porosity, lithofacies). More detailed considerations such as measurements uncertainty, fault-related risks, variations in reservoir thickness, and sequence of field development/production wells.

Caprock Integrity Analysis

Rock Fluid Imaging Lab provides integrated geomechanical analysis considering geomechanic core test, rock physics, lithofacies, temperature, stress state (overburden stress, maximum horizontal stress, minimum horizontal stress, pore pressure, hydrostatic pressure), strain, and reservoir parameter (porosity, lithofacies) combine with Finite Element Modeling for Caprock Integrity Analysis as well as reservoir integrity Analysis.

Caprock integrity, as well as reservoir integrity assessments, have become an essential element in the design and operation of steam injection projects and a critical factor in the selection of a maximum steam injection operating pressure.

Lithology Prediction

Reservoir properties like porosity, permeability and fluid saturation are unique for different rocks. The reservoir properties are very dependent on their lithofacies. Therefore, the first task in reservoir characterization should be lithofacies prediction. Our technologies provide the most accurate prediction using proven sequential flow of reservoir prediction based on lithofacies information.

Our technologies are capable to integrate among weakness and strength of seismic resolution, attributes, well, core, statistical, artificial neural networks and expert experiences to give the most accurate interpretation for reservoir properties prediction.

Fracture Prediction

Fractured reservoir is one of complex reservoir type. To reduce uncertainties in fractured reservoir characterization, we are able to integrate all available data from geology, geophysics, petrophysics and rock physics, using our latest advanced technology based on rock physics, advanced atributes & statistical artificial intelligence.
