Abstract: An apparatus may include a tubular, a first isolator connected to the tubular and configured to engage an interior surface of the wellbore, a first pressure gauge connected to the tubular and configured to take multiple pressure readings over a period of time, and a first perforation gun connected to the tubular without compromising the communication of fluid through an inner flow channel of the tubular. A method may include placing the apparatus in a wellbore, and actuating the isolator to provide isolation of a first zone in a formation. The method may include activating the perforation gun to provide fluid communication between an annulus of the wellbore and the zone in the formation. The method may include allowing the pressure gauge to take a plurality of pressure readings over a period of time. Based on the pressure readings, the method may include determining a formation characteristic.

Abstract: A method of producing hydrocarbons from a tight formation includes injecting a fluid, such as a miscible gas, and retrieving the hydrocarbons. The fluid may be injected into an injection fracture via and retrieved from a recovery fracture. The injection fracture and recovery fractures may be in the same wellbore, the injection fracture may be in a first wellbore and the recovery fracture in a second wellbore, or the injection fracture and recovery fracture may be in a first wellbore and additional injection or recovery fractures may be in a second wellbore.

Abstract: Methods for treating a tar sands formation are described herein. Methods may include heating at least a section of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. The heat may be controlled so that at least a majority of the section reaches an average temperature of between 200° C. and 240° C., which results in visbreaking of at least some hydrocarbons in the section. At least some visbroken hydrocarbon fluids may be produced from the formation.
