    摘要: A method of optimizing drilling ramp-up is provided herein. More specifically, a method of ramping up a drilling operation from a static condition (0, 0) to optimum drilling parameter values (WOB*, RPM*) is provided. The method includes identifying a set of drilling control variables used in forming the wellbore. Examples include weight-on-bit (WOB) and rate of penetration (RPM). The method additionally includes selecting desired control variable values for a first identified drilling stage. The values may be generically referred to as (V1, V2). The method also includes increasing the drilling control variables from (0, 0) to pre-defined drilling control variable values (V1, V2). Preferably, V1 is a WOB value while V2 is a rotation speed value (RPM). The method also comprises monitoring a performance index (PI), wherein (PI) is a combination of torque (TQ) and penetration rate (RPM). The method then includes determining an optimal path to optimum drilling parameter values (WOB*, RPM*) using the Performance Index (PI).

    摘要: Methods and systems for controlling a drilling operation based on an MSE value calculated for a depth increment are disclosed herein. In an exemplary method, drilling parameters characterizing a drilling operation in a subterranean formation are received in a control system. The drilling parameters are used by the control system to calculate a depth-based mechanical specific energy (MSE) based on some amount of energy expended by at least a portion of a drilling assembly while drilling at least one identified depth sub-interval of a depth interval of a subterranean formation. The control system uses the calculated depth-based MSE to control the drilling operation.

    摘要: A method and apparatus associated with the production of hydrocarbons is disclosed. The method, which relates to modeling of drilling equipment, includes constructing one or more design configurations for at least a portion of a bottom hole assembly (BHA) and calculating results from each of the one or more design configurations. The calculated results of the modeling may include one or more performance indices that characterize the BHA vibration performance of the design configurations for operating parameters and boundary conditions that are substantially the same or may be different. These results are then simultaneously displayed for a user to facilitate design selection. The selected BHA design configuration may then be utilized in a well construction operation and thus associated with the production of hydrocarbons.

    摘要: This invention provides a method for improving oil recovery, preferably a high-viscosity oil relying on gravity drainage, by applying vibrational energy. A fracture is created at a wellbore and a fluid displacement device is inserted at or near the fracture opening. The optimum oil mobilization frequency and amplitude is determined. The fluid inside the fracture is oscillated to a prescribed range of frequency and amplitude to improve oil production. Applications for using the fracture as a delivery device for vibrational energy to enhance performance of the steam-assisted gravity drainage process, vapor-extraction gravity drainage, or cyclic steam process are provided. An application to improve recovery of heavy oil by aquifer drive or peripheral waterflood is also provided.
