Estimating shear wave properties to improve hydrocarbon exploration
Underwater seismic acquisition is a standard industry process to collect marine data. The developed method acquires seismic data to estimate reservoir characteristics in a shallow sea water environment. The method involves acquiring seismic data using four component ocean bottom cable using a hydrophone and a three component geophone by varying a time delay between the shots and spacing between the shots. The method leads to the estimation of shear wave properties of a sea bed.
Improves seismic data acquisition and processing
Underwater seismic acquisition is a standard industry process to collect marine data. The developed method enables the processing of multi-component marine seismic data in order to estimate the properties of the seafloor and sensor calibration filters in a shallow water environment. The method applies a time-frequency-wave number transform on the acquired seismic sea bottom data and applies a time varying frequency-wave number filtering process to accurately process the seismic data.
Improves measurement of wettability across any set of reservoir fluids
Reservoir wettability is one of the most important parameters that control many aspects of the performance and quantification of hydrocarbon reservoirs. The developed method determines core wettability characteristics of reservoir rock samples based on a modified form of the Washburn equation. The method involves saturating a core sample with a reservoir fluid such as water and imbibing with another fluid such as oil.
Enhancing the structure of molybdenum disulfide
Sulfur-containing compounds are by-products from oil and gas production. Molybdenum disulfide is the preferred catalyst for hydro-desulphurization, which is the catalytic chemical process to remove sulfur from natural gas or other refined chemical products. However, molybdenum disulfide is limited to the surface area of the material. The developed process expands the surface area of the material by increasing the porosity and internal cavities of the material.
A new binder-free catalyst and a process to produce a designed zeolite-based catalyst with high selectivity. The novel feature of this technology is the use of only catalyst active materials and therefore producing high-quality catalyst through a cost-effective process.

Smart sensors for in-situ measurement for monitoring and fracture mapping during and after geological hydro-fracturing. The sensors records and provides near to real-time data on temperature, pressue, chemical composition, etc. A record set of these sensors can be embedded in the proppant and provide status of the well. All data and information within the fractured rock and any information changes is transmitted wirelessly.

Improving the recovery of bitumen from oil sands
There are almost 10 trillion barrels of heavy oil and bitumen worldwide, of which 10% is commercially exploitable with existing technology. The developed system and method can lead to the recovery of bitumen from oil sands. The environmentally-friendly system incorporates solar-powered generation of steam to increase the viscosity of bitumen and increase the efficiency of recovery.
