Experimental Study on the Effect of Temperature on the Mechanical Properties of Unconsolidated Silty Sandstones

Hydrocarbon reservoirs can be subjected to temperature changes due to different processes during production. Heat injection has become an advantageous method to produce heavy oils in Canada and Venezuela because it increases oil recovery. The heat reduces oil viscosity and oil flows easily. Colombia...
