... Resistance Modelling, CRM) to analyze inter-well communication using only injection and production data. The analytic initially matches production history to determine a potential time response between injectors and producers, and simultaneously calculates the connectivity between each pair of wells. Based...

... between interwell connectivity coefficients and other reservoir parameters. The analytical approach uses a mathematical model for bottomhole pressure responses of injectors and producers in a waterflood system. The model is based on a solution for fully penetrating vertical wells in a closed rectangular...

... of injected water to associated producers, 2) water loss to the aquifer, 3) percentage of oil produced due to each supporting injector, and 4) amount of water cut attributable to each supporting injector. Since the Well Allocation Factor provides the amount fluid attributed to each injector-producer pair...

... Abstract This paper presents an innovative completion technology, fine tuned by reservoir simulations, for balancing the water injection profile into various sand formation zones in an open-hole completed injector well, increasing sweep efficiency. Traditional injection wells often suffer from...

... p ¯ i where σ 2 ii and σ 2 ij are injector-injector and injector-producer covariances respectively. Thus, a set of I +1 equations and I +1 unknowns must be solved for each producer ( Equations 2 and 3 ). The weighting coefficients ß ij obtained from the solution of the N...

... connectivity between injectors and producers in a mature water flood is proposed. The methodology identifies strong connectivities and potential barriers in the field. The method is validated by applying it to a synthetic as well as to field data. This paper was selected for presentation...

In this study, a numerical simulator is acquired to delve into the effectiveness of horizontal and vertical injector/producer well combinations in waterflooding applications. The effects of various waterflooding fluid parameters together with some operational...

During steam injection, heat convection and gravity effects become dominant in the near wellbore area causing excessive heat losses and poor recovery. We suggest...

..., it should contain a minimum oil-in-place of 300 MSTB per pattern length along the trough between the synclinal axis and the gas-oil contact. Optimum steamflood strategy for such reservoirs includes: (1) placing the injector away from the synclinal axis and gas-oil contact, (2) having a row of producers...
