Patent number: 10294759Abstract: The feasibility of performing hydraulic fracturing can be assessed by analyzing the effect of skin on the overall deliverability of a reservoir. Aspects of the disclosure provide a method to determine equivalent skin in hydraulic fractured system through a semi analytical correlation obtained by numerical modeling. Two 3D models are considered: a base case without fracture and a complex case with fractures. The base case is simulated by varying matrix permeabilities while the fractured model is run with different sets of varying fracture's lengths, widths, and permeability as well as matrix permeabilities. The two cases are comparatively analyzed and skin is determined. A generalized correlation for determination of skin is derived through application of multivariate regression technique on obtained skins and their corresponding variables.Type: GrantFiled: April 18, 2017Date of Patent: May 21, 2019Assignee: King Fahd University of Petroleum and MineralsInventors: Rizwan Ahmed Khan, Sami Abdulaziz Alnuaim, Muzammil Hussain Rammay

Publication number: 20170045642Abstract: A method for assessing an inflow performance relationship for a horizontal well in heterogeneous solution gas drives reservoirs. A commercial simulator Eclipse is utilized to develop IPRs for horizontal wells producing oil from solution gas drive reservoirs. Firstly, a simulation model is developed where a base case is considered with typical rock, fluid and reservoir properties using a black oil model. Dimensionless IPR curves are generated by obtaining a set of points relating to flowing bottom-hole pressures to oil production rates. The effects of several reservoir and fluid properties such as bubblepoint pressure, oil gravity, residual oil saturation, critical gas saturation, initial water saturation, porosity and absolute permeabilities on the calculated curves are investigated. A new single empirical IPR model is obtained for horizontal wells producing oil from heterogeneous solution gas drive reservoirs suitable for systems with different reservoir permeability.Type: ApplicationFiled: September 30, 2016Publication date: February 16, 2017Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Muhammad Ali KHALID, Sami Abdulaziz ALNUAIM, Muzammil Hussain RAMMAY

Publication number: 20150199544Abstract: An improved method using fuzzy logic for predicting liquid slip holdup in multiphase flow in pipes. The method improves the Beggs and Brill multiphase flow correlation. Fuzzy sets are defined for all variables in the Beggs Brill liquid-slip holdup equation horizontal multiphase flow. Fuzzy logic is used to calculate the Beggs Brill a, b, and c coefficients from known values for Froude number and the no-slip holdup. Using the Minami and Brill data set and the Abdul Majeed data set the fuzzy logic prediction of liquid slip holdup is compared to the Beggs Brill correlation, the modified Beggs Brill correlation, and several other multiphase correlations. Using a variety of error metrics the fuzzy logic predictions perform better than all other multiphase correlations.Type: ApplicationFiled: January 16, 2014Publication date: July 16, 2015Applicant: King Fahd University of Petroleum and MineralsInventors: Muzammil Hussain RAMMAY, Sami Abdulaziz ALNUAIM
