11865 results about "Oil well" patented technology

An oil well is a boring in the Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released along with the oil. A well that is designed to produce only gas may be termed a gas well.

Integrated reservoir optimization

A method of managing a fluid or gas reservoir is disclosed which assimilates diverse data having different acquisition time scales and spatial scales of coverage for iteratively producing a reservoir development plan that is used for optimizing an overall performance of a reservoir. The method includes: (a) generating an initial reservoir characterization, (b) from the initial reservoir characterization, generating an initial reservoir development plan, (c) when the reservoir development plan is generated, incrementally advancing and generating a capital spending program, (d) when the capital spending program is generated, monitoring a performance of the reservoir by acquiring high rate monitor data from a first set of data measurements taken in the reservoir and using the high rate monitor data to perform well-regional and field-reservoir evaluations, (e) further monitoring the performance of the reservoir by acquiring low rate monitor data from a second set of data measurements taken in the reservoir, (f) assimilating together the high rate monitor data and the low rate monitor data, (g) from the high rate monitor data and the low rate monitor data, determining when it is necessary to update the initial reservoir development plan to produce a newly updated reservoir development plan, (h) when necessary, updating the initial reservoir development plan to produce the newly updated reservoir development plan, and (i) when the newly updated reservoir development plan is produced, repeating steps (c) through (h). A detailed disclosure is provided herein relating to the step (a) for generating the initial reservoir characterization and the step (b) for generating the initial reservoir development plan.

Method and apparatus for autonomous downhole fluid selection with pathway dependent resistance system

An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.

Means for creating field configurable bridge, fracture or soluble insert plugs

A plug for a pipe in an oil or gas well includes a packer, a slip ring and a cone disposable on a mandrel and pressed between an upper push sleeve and a lower anvil on the mandrel. The plug can be field configurable with a frac plug kit, a bridge plug kit and a soluble insert plug kit. A pair of concentric locking rings is disposed between the push sleeve and the mandrel with an outer annular cone with an outer conical shape tapered upwardly and inwardly.

Oil field fracturing pumping remote automatic control system

ActiveCN101414171AMonitor and control operationsOrderly and stable operationTotal factory controlProgramme total factory controlAutomatic controlHuman–machine interface
The invention discloses a remote automatic control system of a fracturing pump skid used in an oil field. The system is used for remote automatic control of a well service pump skid and a truck-mounted skid used in the oil field; the remote automatic control system consists of a field control system which consists of Siemens S7-315 series PLCs which are taken as a core, a Siemens MP370 which is taken as a remote control human-machine interface, and Ethernet which is taken as a transmission media; the system can achieve remote control functions such as start, stop and emergency stop of an engine, gear shifting, braking, turning back to a neutral position and idle speed of a gearbox and the like, and the system can modify field running parameters in a remote manner, thus realizing bidirectional transmission between the pump skid and the human-machine interface (HMI); the Ethernet is taken for communication so that the pump skid can transmit the field data to a remote controller or a server at the speed of 100MB/S; an industrial exchanger is taken to connect the devices such as the PLC, the HMI and the like to achieve more group controls; the exchanger can convert the field data into the data formats such as a standard *.CSV format and the like, and directly transmit the data to the server for data processing.

Pumice containing compositions for cementing a well

A cement composition comprises fine pumice particles, for use in cementing subterranean wells, and oil and gas wells in particular. The pumice containing cement blends feature enhanced compressive strength, and favourable compressive strength to Young's Modulus ratios. Lightweight cement blends containing pumice, and their use in cementing oil and gas wells are also described.

Sleeve valve for controlling fluid flow between a hydrocarbon reservoir and tubing in a well and method for the assembly of a sleeve valve

A sleeve valve for fluid flow between a hydrocarbon reservoir and a well includes a first sleeve and a second sleeve which are relatively movable between a first position in which at least one opening in the first sleeve is aligned or misaligned with at least one opening in the second sleeve in order to admit or shut off the fluid flow. The first sleeve is provided with a radially movable sealing element that has a sealing surface adapted to rest against the second sleeve around the second sleeve opening, and at least one tension element presses the sealing element with its sealing surface against the second sleeve. A method for the assembly of such a sleeve valve includes a sealing element and a tension element placed in the outer sleeve opening and a clamping tool is adapted to the opening in the sealing element and moved outwards together with the sealing element until the sealing element is flush with the inner surface of the outer sleeve. Thereafter, the inner sleeve is inserted into the outer sleeve and the sealing element is allowed to rest against the inner sleeve and the clamping tool is removed.
