Provided is a lateral locating assembly, a well system, and a method. The lateral locating assembly, in at least one aspect, includes a tubular, as well as a bendable deflection tip coupled to the tubular, the bendable deflection tip configured to move between a straight position and a bent position upon the application of fluid pressure thereto. The lateral locating assembly, according to one or more aspects, further includes one or more production ports coupling an interior of the tubular and an exterior of the tubular, as well as a sliding sleeve positioned about the one or more production ports, the sliding sleeve configured to seal the one or more production ports when in a first position and expose the one or more production ports when in a second position.
Gas lift system
A system can include a completion string with a tubing and a dip tube secured in the tubing. A gas is injected into an annulus between the tubing and the dip tube, and the gas and well liquids flow into the dip tube. A method can include installing a completion string including a tubing, a dip tube in the tubing, and a packer downhole of a gas lift valve, and flowing a gas into the tubing via the gas lift valve, into an annulus between the tubing and the dip tube, and then into the dip tube. Another system can include a tubular connector connected between adjacent sections of the tubing, with the dip tube secured in the tubing and connected to the tubular connector. A gas flows from the gas lift valve to the annulus via a gas flow path formed in the tubular connector.
Multilateral acid stimulation process
A main well bore is drilled. The main well bore is completed and stimulated. The main well bore is sealed. A lateral well bore is drilled off the main well bore. A junction that allows communication with the lateral well bore and that connects the main well bore is inserted. The lateral well bore is stimulated through the junction. The main well bore is unsealed, allowing comingled flow from the main bore and the lateral bore.
DUAL WELL, DUAL PUMP PRODUCTION
Methods and systems for producing hydrocarbons. An example method includes producing a non-hydrocarbon liquid from a first horizontal wellbore, the first horizontal wellbore extending from a vertical wellbore and through a hydrocarbon producing formation. The method further includes pumping the non-hydrocarbon liquid with a first pump into a second horizontal wellbore, the second horizontal wellbore extending from the vertical wellbore and disposed downhole and underneath the first horizontal wellbore. The method additionally includes pumping a hydrocarbon liquid uphole to a surface with a second pump disposed downhole of the first horizontal wellbore.
Energy transfer mechanism for wellbore junction assembly
A unitary multilateral junction for deployment in a wellbore, wherein the multilateral junction permits electrical power and communications signals to be established in both a lateral wellbore and a main wellbore utilizing capacitive coupling and a cavity resonator. The unitary junction assembly generally includes a conduit with a first upper aperture, a first lower aperture and a second lower aperture where the first lower aperture is defined at the distal end of a primary passageway extending from a conduit junction and a second lower aperture defined at the distal end of a lateral passageway extending from the conduit junction. A lower wireless energy transfer mechanism in the form of a capacitive coupler is positioned along at least one of the passageways between the distal end of the passageway and the junction. A cavity resonator is adjacent the capacitive coupler to enhance the electric field signal of the capacitive coupler.
Deflector assembly and efficient method for multi-stage fracturing a multilateral well using the same
Provided, in one aspect, is a deflector assembly. The deflector assembly, in one embodiment, includes a deflector body having a deflector window located therein, and a deflector ramp positioned at least partially across the deflector window, the deflector ramp configured to move between first ({circle around (1)}), second ({circle around (2)}) and third ({circle around (3)}) different positions when a downhole tool moves back and forth within the deflector body.
METHODS OF PRODUCING HYDROCARBONS FROM UNCONSOLIDATED SAND FORMATIONS
A method of drilling an uncompleted lateral wellbore in a subsurface formation includes drilling the uncompleted lateral wellbore with coiled tubing in the subsurface formation. The subsurface formation includes unconsolidated sand and the subsurface formation overlays a water-saturated reservoir. The method may further include introducing particles having an average particle size of from 8 mesh to 140 mesh into the uncompleted lateral wellbore, thereby supporting the uncompleted lateral wellbore and avoiding wellbore collapse and installing a screen in a vertical wellbore fluidly connected to the uncompleted lateral wellbore, wherein the screen has a mesh size of from 325 mesh to 1000 mesh. The subsurface formation may include hydrocarbons and the method may further include producing hydrocarbons from the subsurface formation.
Smart completion maximum reservoir contact (MRC) well optimization model
Systems and methods include a method for optimizing maximum reservoir contact wells. For each lateral of a multi-lateral well and using input data for the lateral, a lateral flowrate is determined for each opening position for different combinations of internal control valve (ICV) sizes and target flowing bottomhole pressures. Using a numerical model, an estimated total flowrate is determined for each lateral based on the lateral's flowrate. Options are provided for presentation to a user in a user interface for changing ICV settings of the multi-lateral well. Each option includes a predicted added value to production of the multi-lateral well. The predicted added value includes one or more of an individual lateral production contribution, an enhanced sweep efficiency for one or more laterals, or a water rate reduction. A selection by the user of an option is received. The option is implemented during production of the multi-lateral well.
Travel Joint For Tubular Well Components
An apparatus for downhole connection of well components includes a first tubular component defining a through bore for receiving a second tubular component and a travel joint including an axially moveable inner sleeve and a coupling feature configured for coupling the second tubular component with the inner sleeve when received in the through bore of the first tubular component.
Wellbore sealing system with degradable whipstock
A wellbore sealing system is disclosed. The wellbore sealing system includes a deflection assembly positioned in a main wellbore and a junction coupled to an uphole end of the completion deflector and extending into the lateral wellbore to form a fluid and pressure tight seal. The deflection assembly includes a degradable whipstock configured to laterally deflect a drill bit such that the drill bit drills through a sidewall of the main wellbore to form a lateral wellbore, a completion deflector coupled to and located downhole from the whipstock, and an anchoring device coupled to and located downhole from the completion deflector to prevent the deflection assembly from rotating and moving in an uphole direction and a downhole direction within the main wellbore.
