Plaster and composites made up of gypsum have been extensively used in building for various purposes. This work aims to study the use of polypropylene (synthetic polymer), Alfa (Stipa tenacissima ) and plastic waste as fiber in the manufacture of plaster and mortar plaster . In this study, a Superplasticizer was used to improve the fluidity of the plaster grout and mortar plaster. The optimization of the dosage of superplasticizer of plaster grout without fiber was determined based on the mechanical strength tests...

Many oil and gas low permeable reservoirs have been stimulated to enhance productivity. Acid fracturing is one of the commonly used well stimulation treatment in carbonate formations, such as limestone, dolomite, and chalk. Carbonate reservoirs are good candidates for acid fracturing since strong acids such as hydrochloric acid react easily with carbonate. The acid reacts within the fracture to create a differentially etched surface that will maintain a conductive pathway. Habitually, a pad fluid is injected ahead...

The interpretation of well tests is a tool for the detection of well and reservoir problems, which based on the determination of several parameters such as permeability, skin, average reservoir pressure, flow capacity (kh ), effective length, boundary reservoir, and type of wellbore storage, etc. The knowledge of these parameters will allow us to make the production forecast and the resolution of production problems. For this, We have chosen six production wells located in the Haoud Berkaoui oil field, the interpr...
