Abstract: A method for quantifying frac hits within a few days using a novel pressure-transient analysis technique called differential pressure-transient analysis (DPTA). Unlike pressure transient analysis (PTA) methods, focused on single-well analyses, DPTA evaluates pressure response from two or more wells simultaneously to (1) determine the existence of frac hits, and (2) determine the magnitude of interference, defined as the ratio of inter-connected to total number of primary fractures from a given well. The output from (2) can be subsequently used to accurately predict oil and/or gas production rates for infill and offset wells.

Abstract: A method of forecasting well production in an accurate and computational cost-efficient manner implementing a hybrid, iterative approach which is computationally efficient, numerically stable, and improves the accuracy of results. The iterative method of forecasting well production can estimate a set of scaling factor, determining the average adjusted pressure in the matrix, conductive reservoir volume, and oriented hydraulic fracture, applying an algorithm to convert the average adjusted pressure to an actual average pressure, using actual average reservoir pressure to estimate a new set of scaling factor, estimating a relative error based upon the new scaling factor, determining if the relative error is within a user-defined tolerance, and performing the above steps again if relative error is not within the user-defined tolerance or storing the new scaling factors. The new scaling factors can be used to determine a production rate.

Abstract: A recursive method of optimizing rate of penetration while drilling a well. The method can include collecting historical data on a plurality of drilling parameters, performing a mathematical analysis on the historical data to correlate each drilling parameter to a rate of penetration, determining an importance of each drilling parameter, establishing an operating envelope for each drilling parameter, and adjusting at least one drilling parameter to achieve a desired rate of penetration. The steps can then be repeated at a user defined interval.

Unlike pressure transient analysis (PTA) methods, focused on single-well analyses, DPTA evaluates pressure response from two or more wells simultaneously to (1) determine the existence of frac hits, and (2) determine the degree of interference, defined as the ratio of inter-connected to total number of primary fractures from a given well. The output from (2) can be subsequently used to accurately predict oil and/or gas production rates for infill and offset wells.
