Geomechanics Technologies, Inc. is assessing the available data from wells in the Ship Shoal block 107 area within the Gulf of Mexico (Figure 1) and reviewing publicly available geological and seismic data to evaluate CO2 storage potential resource. The project is analyzing the Ship Shoal Block 107 in detail by preparing a high resolution 3D geologic model and integrated geomechanical and fluid flow models. The objective of this project is to characterize the Neogene delta sands in the Ship Shoal Area for large scale CO2 sequestration. This is being accomplished through a research program that includes: 1) evaluation of available exploration and development well logs and all available geologic and geophysical data in the public domain; 2) development of 3D geologic models to depict a representation of the subsurface geology to support the prediction of CO2 storage capacity within 30 percent; 3) development of a CO2 injection model to simulate CO2 migration and containment in the Ship Shoal 107 field; 4) development of a 3D geomechanical model to simulate induced stresses and potential fault reactivation due to CO2 injection in the vicinity of typical faulted structures; 5) performing a comprehensive evaluation of storage capacity and seals; and 6) performing a risk assessment and analysis of existing oil and gas infrastructure for CO2 transportation and providing recommendations for a potential transportation pipeline corridor.

Project Benefits

A static geologic model is being established using data from 54 wells that will allow refined individual cells or voxels to be built. These individual lithologic voxels provide an accurate volume for calculating COstorage capacity for each lithologic type within the Ship Shoal Block 107 field. The voxels are exported into gas migration models that are designed to simulate CO2 injection for 30 years and monitoring for an additional 30 years. The results allow for the prediction of the amount of COthat can be injected into a single well location, the potential for cap rock leakage, whether or not the plume will stabilize after 30 years of injection and 30 additional years of observation, and whether depleted reservoir pressure inhibits plume migration.
