Definitions

  • the invention relates to resource extraction modelling systems and/or methods for modelling resource extraction.
  • the invention provides a resource extraction modelling system, comprising:
  • This system is particularly advantageous because it allows an improvement in the probability of correctly locating the first drilling location.
  • the drilling of so called dry holes is also minimised if not avoided altogether. It also allows improved accuracy for predicting the levels of extraction from a given site without having to physically drill.
  • As a secondary advantage it also allows the prioritisation of the drilling operation for an entire field. This maximises the likely resource extractable from the field whilst reducing material costs and labour.
  • the system further comprises one or more volumetric displays for displaying a volumetric model representative of the operation of said selected drilling and/or extraction structure at a particular location for resource extraction.
  • This configuration allows the team of drilling experts to visualise the effect of a chosen drilling angle on the exploration. It also allows multiple angles to be assessed by simply changing viewpoint. It also minimises the likelihood of obtaining dry holes.
  • the system is also likely to accelerate the production profile. It also maximises the likely delivery of base reserves and therefore increases recovery. This would also allow engineers to obtain a birds' eye view of an entire operation.
  • the volumetric display is holographic with a portion being representative of a rig. This would allow real time analysis of data. It would achieve next to no carbon emissions. It would allow a method of exploration structure set up which would not optionally comprise the step of having to use an actual rig for drilling. Safety improvement if not complete safety when drilling operations are monitored from the relative comfort of a volumetric display which may be a so called holographic theatre in the drilling operations' office.
  • means are provided to allow an operator to input operational conditions selected from the group comprising: temperature, seabed type, weather, marine conditions, salinity, seasonal conditions and wind direction.
  • two separate volumetric displays are employed: one of the displays being selected for the modelling of said drilling and/or said extraction structure whilst the second display models said region for potential resource extraction.
  • said volumetric display is tower shaped and higher than it is wide. This configuration is particularly advantageous because it marks a complete departure from the prior art display units, which are primarily wider than they are high.
  • said volumetric display incorporates an array of light emitting voxels positioned within a three-dimensional space. This allows the system to be implemented for example every context of a board meeting without requiring special lighting conditions in a given assessment station.
  • the invention provides a method for modelling resource extraction, comprising the steps of:
  • the method comprises the step of displaying on a volumetric display a volumetric model representative of the operation of said selected drilling and/or extraction structure on a particular location for resource extraction.
  • This method is particularly advantageous because it allows the operator to select a drilling and/or extraction structure and assess its effect on a location for resource extraction. It also allows the drilling action to be observed from a plurality of angles.
  • the method comprises the step of inputting operational conditions selected from the group comprising: temperature, seabed type, weather, marine conditions, salinity, seasonal conditions and wind direction.
  • the method comprises the step of calculating and displaying the rate.of extraction for a particular location. This method also allows the operators to prioritise the actual drilling and/or resource extraction operation with both a long-term view and a short-term view.
  • Figure 1 shows a schematic view of the system in accordance with a first embodiment of the invention.
  • Figure 2 shows a volumetric display unit and a controller in accordance with a second embodiment of the invention.
  • FIG. 3 shows a flow diagram of the steps followed in an embodiment of the invention.
  • FIG. 1 generally shows an overview of the system in the form of a volumetric segment generally referenced 1, where a layer of sea 2 is illustrated above a seabed 3 and a potential resource extraction layer 4.
  • seabed 2 a number of seismic cables such as cable 5 are placed. Such cables may be located underneath the upper surface 6 of the seabed in order to protect the cables from damage.
  • the cables incorporate a plurality of regularly spaced sensors 7 which are adapted to receive signals reflected from an underground region 4.
  • a seismic source is fired by vessel 8 as shown by arrows 9.
  • the reflected signals are illustrated by arrows 10.
  • a gas cloud, a gas and/or an oil pocket such as pocket 11 will tend to attenuate or modify in known ways the seismic pressure waves. Some pressure waves will be for example converted into shear waves.
  • the reflected seismic signals are picked up by individual sensors and are then recorded at an off-shore platform.
  • the link between the cables and the platform may be established between a canister 12 located at least in part in the seabed for housing and/or protecting the electrical equipment necessary for driving the sensors and for relaying the information to a platform.
  • the data gathered at an off-shore platform is then transferred to an on-shore processing location through an optical cable which may itself be imbedded into the seabed.
  • a hydrophone may be placed about the seabed to generate a signal in the form of sound waves, which return to a shooting vessel such as vessel 8 and are then relayed to appropriate processing means.
  • the elements of figure 1 can be converted into a volumetric display by for example employing a three-dimensional array of voxels, which may be light emitting.
  • An example of a suitable arrays is detailed in US 5,801,666 which is enclosed by reference.
  • Means may be provided to vary the colour of individual voxels to present the combination of a mapped underground region for potential resource extraction in combination with a drilling rig such as drilling rig 13 in figure 1 which is connected to an oil pocket 11 via a drilling line 14.
  • a controller In order to illuminate individual voxels, a controller is provided in order to drive an optical switch which selectively sends beams of light to appropriate voxels in the array.
  • Figure 2 shows an array 15 with a plurality of voxels such as voxels 16.
  • figure 2 only shows the first of the volumetric displays.
  • the number of voxel selected is sufficient to clearly indicate the three-dimensional size of a given oil pocket and to show its interaction with a drilling rig.
  • the volumetric display is preferably higher than it is wide. It is envisaged that the lower region referenced 17 will depict the potential resource extracting region whilst region 18 would depict the drilling rig and/or alternative resource extraction structure such as a conductor supported well.
  • the system's controller provides means for inputting the three-dimensional resource data gathered through the seismic array.
  • Drilling engineers and/or experts and/or board members would be able to employ the controller to select particular drilling structures from known kind and to view the positioning of the drilling line relative to an oil line in order to view the drilling and/or resource extraction performance for various positions of the drilling line dependant upon the resource data and specific environmental data.
  • This approach will have the particular benefits of reducing substantially the required drilling time and therefore the expense for the drilling since hotspots may be assessed by a reservoir engineer using this method without having to dive under water or send further equipment to drill. There would also be considerable health, safety and environmental benefits due to the reduction in drilling time. There would also be faster and more efficient drilling programs deployed which would resort in an acceleration of the field development. This approach will also allow an improved interface between the off-shore drilling team and the on-shore team to optimise drilling programs.
