The invention relates to a method of performing production operations of an oilfield having at least one process facility and at least one wellsite operatively connected thereto, each at least one wellsite having a wellbore penetrating a subterranean formation for extracting fluid from an underground reservoir therein. The method steps include receiving a number of steps each from at least one of a number of collaborators, specifying an automated workflow including the number of steps and for generating a first well plan, obtaining first data associated with the production operations, applying the automated workflow to the first data to generate the first well plan, adjusting the production operations based on the first well plan, and modifying at least one of the number of steps based on input from at least one of the number of collaborators to generate an updated automated workflow.

System and method for performing oilfield simulation operations

Disclosed is a system and method for directing data representing well operations (drilling and producing) through the Internet or similar wide area network. The instant invention comprises a system and method of installing sensors at the well to provide technical information to remotely-located Internet users who provide services to the well owner. The service providers may be observers, who may then advise the well owners and operators as to actions to take to increase or optimize well performance. Service providers may also be data storage companies, who clean and store the data from the well. Service providers may then be paid from a portion of the well revenues or a portion of the incrementally-increased revenues.

Well data collection system and method

A method is disclosed for generating a wellsite design, comprising: designing a workflow for an Earth Model; building an initial Earth Model based on the workflow adapted for modeling drilling and completions operations in a hydrocarbon reservoir; calibrating the initial Earth Model thereby generating a calibrated Earth Model; and generating the wellsite design using the calibrated Earth Model

Method and system for designing and optimizing drilling and completion operations in hydrocarbon reservoirs

A system and method is provided for optimizing production from a well. A plurality of sensors are positioned to sense a variety of production related parameters in a well having a gas lift system. The sensed parameters are used in creating measured data that can be applied against a well model. Discrepancies between the well model and the measured data are used to determine factors contributing to sub-optimal well performance.

System and method for optimizing production in an artificially lifted well

A wellbore pressure isolation apparatus is deployed in a wellbore and has a sealing element that can be activated to seal against an interior surface of a surrounding tubular. Once set, a ball valve in the apparatus restricts upward fluid communication through the apparatus, and another ball valve in the apparatus can restrict downward fluid communication through the apparatus. These ball valve can have disintegratable balls intended to disintegrate in wellbore conditions after different periods of time. To facilitate deployment of the apparatus in a horizontal section of the well bore, the apparatus has a plurality of rollers positioned on a distal end. In addition, the apparatus has a ring disposed about the body between the distal body portion and an adjacent body portion. The ring has an outside diameter at least greater than that of the adjacent body portion to facilitate pumping of the apparatus in the wellbore.

Remote control and monitoring of oil and gas production wells

A method for plugging wells for use in connection with extraction of a fluid. Above a leakage site in the well, from which the fluid flows into the well from a subsurface formation surrounding the well, there is a set a seal (20), which seals the well, and on the bottom of which is a sensor device (22) for measuring well data. On the top of the seal (20) is a connecting part (24) which is connected to the sensor. Above the seal (20) the well is filled with a temperable, liquid sealant (32), into which is lowered via a cable (38) a connecting device (40) with a connecting part (42) until the connecting parts (24, 42) have been connected. Both the lowering and this connection are provided by means of the weight of the connecting device (40). The cable (38) is connected to a logging device (50) outside the well opening and the sealant (32) is set.

Method for installing a sensor in connection with plugging a well

The invention relates to a switch device (1) which sequentially conducts one hydraulic fluid stream (2) to two or more independently operated hydraulic units, where the switch device (1) with one or more channel throughputs (11, 12, 13 and 14) travels helically in a holding cylinder and transfers pressure streams in rotational sequence via fixed channels (8 and 8') in the holding cylinder to separately operated hydraulic devices. With activation and deactivation in succession with alternate pressure and pressure relief combined with corresponding spring device (4), the switch device (1) in the surrounding cylinder is simultaneously forced to perform a one-way helical and axial forward and backward movement, resulting in altered fluid communication. Full switch rotation is achieved with, for example, six equiangular waves, each at 60°, or with six different angular waves, such as 90° + 60° + 45° + 60° + 60° + 45°.
