Joshi Technologies International, Inc. is a leader in the application of horizontal well technology. Clients include major oi ... l companies, independents, and national oil companies. JTI has over 200 combined years experience on staff in horizontal and conventional wells including reservoir engineering, completion and drilling design, along with experience in oil, gas, gas-condensate, heavy oil and gas storage reservoirs. Sada Joshi, Ph.D., founder of Joshi Technologies International Inc., is the author of the best-selling book, Horizontal Well Technology, published by PennWell of Tulsa, 1991. JTI offers responsive customer support and consulting services. Our software JTI.Horizontal™, PROCONE® and MultiLateral™, put advanced technology in the hands of petroleum engineers. The programs are practical, easy-to-use tools which enable the engineer to forecast or evaluate well performance under various conditions. They use analytical (non-numerical) methods for fast execution and easy data requirements. The programs have history-matching features to graphically compare calculated and actual rates, enabling estimation of reservoir properties (e.g. horizontal or vertical permeability, drainage area, etc.) from production history. JTI.Horizontal and ProCone have sensitivity features to show the effect of variables or unknowns on rates and reserves in graphical form. JTI.Horizontal calculates either rates or pressure versus time for vertical, hydraulically fractured, horizontal, or multiple fractured horizontal wells. PROCONE performs coning calculations for vertical or horizontal wells. MultiLateral Horizontal calculates either rates or pressure versus time of reservoirs with multiple drainholes that can be used for stand-alone evaluations or as a screening tool for more in-depth studies. read more
