Method for integrated enhanced oil recovery from heterogeneous reservoirs

Номер: US20120125616A1
Автор: Arne Graue
Принадлежит: Bergen Teknologioverforing AS

The invention relates to a method of recovering oil from a heterogeneous reservoir, comprising a plurality of permeable porous blocks of rock whose pores contain oil and which form interfaces with regions between the blocks, e.g. fractures, having a higher permeability than the blocks. The method comprises the steps of treating the interfaces such that the wettability of the surfaces of the blocks is in a predetermined wettability range, then reducing the permeability in the highly permeable regions, and finally flooding the reservoir by injecting a chase fluid into the reservoir. With the inventive method water phase bridges are established between adjacent blocks in the reservoir thus allowing a transmission of injection pressure for viscous displacement from one block to the next across the reservoir. The invention also relates to a method for long-time storage of CO 2 by using CO 2 as chase fluid or foaming gas according to the inventive method for oil recovery from heterogeneous reservoirs.

The predictive model is operated so as to generate predicted data indicative of a predicted additional amount of oil, compared to the predetermined volume of oil, that will be displaced by configuring the crude oil displacement system so as to inject the displacement fluid having the chemical characteristics into the one or more reservoirs. On the basis of the predicted data, the one or more operating modes of the crude oil displacement system are determined. A further computer-implemented method employing the predictive model in which predicted data indicative of one or more predicted chemical characteristics of the displacement fluid are generated is also provided.

A harvester ( 10 ) with warm water spray jets ( 11 ) that fluidizes and releases gas hydrates from seafloor sand and soil. The released gas hydrates float into the harvester ( 10 ) and are then transferred through a hydrate slurry pipe ( 14 ) to a separation vessel ( 18 ). Dissociation of the gas hydrates into methane gas occurs in the separation vessel ( 18 ) from its lower pressure than the seafloor and the optional use of heat. The liberated methane gas flows upward in a gas vent pipe ( 27 ) to a topside vessel ( 30 ) for storage from the pressure of the submerged separation vessel ( 18 ). Alternatively, the vent pipe can be fed directly into an available natural gas pipeline. Crude oil collected in the separation vessel ( 18 ) can be separated and pumped to a topside vessel ( 30 ) for storage and use in a refinery. No other processing is required to produce commercial quality natural gas harvested directly from gas hydrates on or near the seafloor.

A fracturing jet nozzle assembly features a series of angles nozzles on a rotatably mounted plate that operates in conjunction with a central nozzle or nozzles. The slanted nozzles are aimed into the perforation where the central nozzle is aimed directly so that the rotation of the nozzle plate from the slanted nozzles results in cyclic impacts in the perforation from where the fractures will propagate. The cyclic loading results in greater fracture formation and propagation. In another variation, relatively movable plates employing slanted nozzles rotate one plate with respect to another to get the effect of cyclic pulses of jetting fluid impingement in the perforation to enhance formation and propagation of fractures from the perforation.

A method of controlling a fluid jet can include discharging fluid through an outlet of a jetting device, thereby causing the fluid jet to be flowed in multiple non-coplanar directions, and the fluid jet being directed in the non-coplanar directions by a fluidic circuit of the jetting device. A jetting device can include a body having at least one outlet, and a fluidic circuit which directs a fluid jet to flow from the outlet in multiple non-coplanar directions without rotation of the outlet. A method of drilling a wellbore can include flowing fluid through a fluidic switch of a jetting device, thereby causing a fluid jet to be discharged in multiple non-coplanar directions from the jetting device, and the fluid jet cutting into an earth formation.

A magnet assembly can be attached to, or placed in the vicinity of, a conventional bell nipple to generate a magnetic field within the central bore of the bell nipple. The magnetic field catches falling metal objects and prevents such objects from passing beyond the bell nipple and entering the subterranean portions of a wellbore. An optional diverter assembly slows the velocity of falling metal objects before reaching the magnet assembly, while also wiping the outer surface of pipe or other items lowered into a wellbore.

Annular Gap Debris Barrier

Номер: US20130032332A1
Автор: Donald T. Heckel, James R. Zachman
Принадлежит: Baker Hughes Inc

A debris barrier snap fits to a tubular groove of one of the tubulars that define the annular gap in which the barrier is to be mounted. It is loosely mounted so that it can center itself in the annulus as the relatively moving members go out of a concentric arrangement. The continuous carbon fiber material used for the debris barrier has lubricious qualities to act as a bushing when the annulus shape changes due to movement of the tubulars out of a concentric relationship. An outer or inner groove on the barrier acts to trap and retain small particles that manage to advance between the barrier and the outer tubular. The snap fit is accomplished with flexible spaced apart fingers with grip surfaces to engage a groove on one of the tubulars. The barrier has low expansion under thermal loads to retain the clearance that acts to stop the entrance of debris.

Method for quantitatively assessing connectivity for well pairs at varying frequencies. A time series of measurements ( 12 ) is chosen for each of the two wells such that the particular measurements will be sensitive to subsurface connectivity if it exists ( 11 ). The two time series may then be pre-processed by resampling to time intervals commensurate with response time between the two wells ( 13 ), detrending the measurements ( 14 ), and detecting and eliminating spiking noises ( 15 ). Then the time series are transformed to the frequency domain where coherence and phase between the two series are compared for varying frequencies ( 16 ). This comparison is used to make a determination of connectivity.

A computer system and method of automatically generating a Local Grid Refinement (LGR) gridded model of a gas reservoir. A geologic file includes information identifying the locations of one or more wells according to root grid cells within a volume of the earth to be modeled. User inputs specify the number of hydraulic fractures from each well, and such parameters as the fracture length, etc. User inputs also specify the number of “splits” of the root grid cells containing hydraulic fractures; those root grid cells are then split into finer resolution grid cells of increasing width within the root grid cells containing the fractures. For horizontal wells, user inputs indicate the number of splits of root grid cells containing the lateral portions of the wellbore. Non-orthogonal and complex fractures are processed by a “nested” LGR approach. Geologic properties are assigned to each grid cell, with a tensorial adjustment included for non-orthogonal fractures, and the resulting model is available for simulation. 1.

Method for constructing a fracture network grid from a voronoi diagram

Номер: US20130138406A1
Автор: Matthieu Delorme, Nina Khvoenkova
Принадлежит: IFP Energies Nouvelles IFPEN

Method for optimizing the development of a fluid deposit using a fracture network grid constructed from a Voronoi diagram. Based on observations of the deposit a discrete fracture network is constructed in which each fracture is represented by an isotropic polygonal finite plane in terms of its dynamic properties, a plane comprising segments of intersection with other network fractures. A Voronoi diagram is constructed on each fracture plane by positioning Voronoi cell centers on the segments of intersection, and the transmissivities are calculated between centers of neighboring cells from the ratio between the surface area of the neighboring cells and the distance between the neighboring cells. The cells and transmissivities can then be used to construct an image of the fluid deposit. Finally, this image and a flow simulator are used to optimize the development of the fluid deposit.
