Optimisation De Production Dans Un Réservoir '' Tight " Cas Du Réservoir Ordovicien Du Champ Hga

Résumé: Tight Reservoirs are reservoirs with low permeability and low effective porosity, which put production in question. In Algeria, these reservoirs are distributed everywhere taking as an example the field of Hassi Guettar whose central part will be referred to in this memoir where we will approach the interventions carried out in our study area, in order to improve the production of the field. First, the hydraulic fracturing and the three (03) wells which it was carried out on HGA26, HGA38 and HGA40 whose these last two did not achieve unfortunately. Then, the application of Short Radius for the first time in the field of HGA on the well HGA40, where the operation was successfully completed, and the three wells candidates (03); HGA36 which we proposed its recovery in SR if the deepening option will not be helpful. Concerning the other two (02) wells HGA38 and HGA42 they are both canceled, due to the difficulties encountered. Finally, we established an economic study, which serves to evaluate the short radius investment of the well HGA40, which has proved this well as being profitable, and has shown encouraging results for another uses on other wells.
