NXT Energy Solutions Inc. announced the first international patent of the Stress Field Detection Technology and the development of a new generation of sensors that will enhance the company's ability to provide higher quality survey results. The company is also provide an update in respect to the current contract negotiations with a number of prospective international clients. The company also announce a positive development in strategy to obtain worldwide patent protection for the SFD technology. A decision to grant an international patent has been made for the airborne SFD technology application, which, based on quantum mechanical principles, is the first of its kind to have been commercially developed. In addition, NXT has patent applications pending in numerous international jurisdictions. SFD Sensor Development: NXT's technical team, led by George Liszicasz, has spent considerable time over the course of 2016 on successfully developing and field-testing a new generation of SFD sensors based on unique configurations of sensor elements. The new design will provide the following enhanced features to survey process: Higher detection sensitivity to gravitational sources of interest, providing clients with better delineation of subsurface trapped fluid systems (potential hydrocarbon reservoirs) Greater clarity and differentiation of individual geological anomalies. Increased sensor stability and signal integrity that are expected to significantly improve the efficiency and accuracy of the interpretation process. The design advancements are being incorporated in a new patent application.
