Definitions

  • the present invention relates to a reservoir monitoring system for use in a downwell environment .
  • Downwell reservoir monitoring systems are widely used in the oil industry to gather information on hydrocarbon bearing formations .
  • WO03 /058282 describes a reservoir-monitoring unit that is operable to collect pressure and temperature data from downwell sensors that are provided within the production tubing of a completed well .
  • the monitoring unit is placed in one well and used to monitor activity in an adjacent well .
  • Data is sent to a surface station using acoustic signals . Whilst this arrangement can provide useful data, a problem with it , and other systems of this general type, is that the production tubing has to be perforated in order for the sensors to be exposed to the hydrocarbon formation.
  • a reservoir monitoring system comprising : means for monitoring one or more parameters associated with a hydrocarbon reservoir, and a transmitter for transmitting monitored data to a monitoring station, wherein the monitoring means is carried on an external surface of a hydrocarbon production pipe, casing or tubing and includes means for forming an opening into the hydrocarbon reservoir without perforating the pipe, casing or tubing .
  • the transmitter may be operable to transmit data without using electric or hydraulic cabling.
  • the transmitter may be operable to transmit data via the pipe, casing or tubing .
  • the hydrocarbon production pipe, casing and/or tubing may be made of metal .
  • the monitoring means may include a pressure gauge and/or a temperature sensor for measuring the pressure and/or temperature of the hydrocarbon in the hydrocarbon reservoir .
  • the monitoring means may include a battery for powering one or more of its components , for example the pressure gauge and/or temperature sensor .
  • the means for forming an opening into the hydrocarbon reservoir may comprise perforation means .
  • the perforation means may be pressure activatable .
  • the perforation means may include a pressure activatable firing gun.
  • a pressure release valve may be provided between the pipe, casing or tubing and the firing gun, wherein release of the valve is operable to activate the firing gun.
  • Each monitoring means may include a radioactive marker. This can be used to determine the depth of the monitoring module by correlating the strength of a signal received at a surface station with pre-determined data in a radiation log.
  • a plurality of monitoring means may be provided on a single length of pipe , casing or tubing. In this way, multiple intervals can be monitored in a single bore .
  • Monitoring means may be provided on a plurality of separate wells . When arranged in this way, the monitoring means allow zonal connectivity between wells to be monitored. According to another aspect of the invention, there is provided a means for monitoring one or more parameters associated with a hydrocarbon reservoir, wherein the monitoring means are operable to be carried on an external surface of a hydrocarbon production pipe, casing or tubing and include means for forming an opening into the hydrocarbon reservoir without perforating the pipe, casing or tubing .
  • a method for monitoring a hydrocarbon reservoir comprising : providing monitoring means on an external surface of a hydrocarbon production pipe, casing or tubing; , forming an opening into the hydrocarbon reservoir without perforating the pipe, casing or tubing; monitoring one or more parameters associated with the reservoir, and transmitting monitored data to a monitoring station.
  • multiple monitoring means are provided so that multiple intervals in a single wellbore can be monitored.
  • Multiple wells in a field may be monitored simultaneously by providing monitoring means in different wells .
  • This provides the ability to monitor zonal connectivity between wells in a field, and provides the opportunity to model well drainage and reservoir reserves . By doing this prior to perforating an interval (s) , real time data can be provided to allow a perforation and/or fracturing/stimulation strategy to be developed.
  • Figure 1 is a cross section through a part of a reservoir monitoring system
  • Figures 2 to 5 show a sequence of steps that are taken in use of the system of Figure 1.
  • FIG. 1 shows a metal production tube 10 on an external surface of which is mounted a monitoring unit 12.
  • the monitoring unit 12 includes a wireless monitoring module 14 for monitoring one or more characteristics or parameters of a reservoir .
  • This has a downhole pressure and temperature gauge (not shown) for measuring pressure and temperature, a battery pack for powering all of the module' s components and a signal transmitter/transceiver for wirelessly transmitting data to a surface station via the metal tubing 10.
  • a downhole pressure and temperature gauge not shown
  • a battery pack for powering all of the module' s components
  • a signal transmitter/transceiver for wirelessly transmitting data to a surface station via the metal tubing 10.
  • To transmit data in this way there has to be some form of electrically conducting path between the transmitter and the tubing 10 , so that an electromagnetic signal generated by the transmitter can be coupled onto the tubing 10. Techniques for doing this are well known in the art and so will not be described in detail .
  • Adjacent the wireless module 14 is a radioactive marker 16. This is provided to allow the depth of the unit to be determined. As is well known in the art , this can be done by correlating the radioactive signal received from the marker with a pre-determined formation log . Also provided is a perforation unit 18 that is operable to perforate material that surrounds the unit and so form one or more openings into the hydrocarbon reservoir. Between the perforation unit 18 and the pressure/temperature gauge in the wireless module 14 is a pressure path so that the gauge can be used to measure accurately the pressure in the hydrocarbon formation.
  • the perforation unit 18 has a perforation gun 20 with a pressure activated firing head 22 that causes the gun 20 to fire when the pressure exceeds a pre-determined threshold.
  • a pressure release valve 24 is positioned between the tubing 10 and the firing head cavity 26. When the pressure in the tubing 10 is increased above the predetermined threshold, the release valve 24 opens and the firing head 22 is exposed to that increased pressure. This causes the head 22 to fire, thereby activating the perforation gun 20.
  • the perforation gun is arranged to fire explosive shots outwardly from the tubing 10 and substantially perpendicular thereto .
  • a debris collection unit 30 for collecting the debris that results when the gun 20 is fired.
  • each length of tubing 10 typically carries a plurality of monitoring units 14.
  • the position of the units 14 is correlated to the required setting depth using the radioactive markers 16 as a guide.
  • the string is cemented in place using standard cementing techniques, see Figure 3.
  • pressure is applied to the tubing 10 to open each pressure release valve 24 , and thereby open a pressure path between it and its associated perforating assembly. In some circumstances , it may be desirable to have different perforation units 18 activated at different time .
  • the relief valves 24 in the units 14 may have different ratings , so that they can be activated in a variety of sequences .
  • the pressure activates each firing head 20 , and initiates an explosive train, which perforates the material surrounding the monitoring unit and forms a plurality of openings 32 into the reservoir/formation 34 , as shown in Figure 4.
  • any perforation debris that is generated is caught by the debris collection unit 30.
  • the formation pressure then enters the monitoring unit 14 and, in particular, the pressure and temperature gauge . Real time pressure and temperature data can then be collected and relayed to a surface receiver via the downhole transmitter, using the pipe 10 as the data transmission conduit .
  • reservoir pressure and temperature can be monitored in real time via metallic connections to the wellbore tubulars or surface equipment, without " wireline intervention and without breaching tubing integrity.
  • data signals can be collected, be transmitted further along pipelines to the collection point, or indeed stored and collected later by, for example, dropping a sonde . Intervals can then be monitored and selectively perforated as required, as shown in Figure 5.
  • the wireless reservoir monitoring system in which the invention is embodied is able to establish communications between a wireless downhole gauge and a reservoir section in order to monitor reservoir pressure and temperature remotely via a surface read-out . This can be done throughout the lifetime of the well .
  • the system uses the wellbore tubulars , as well as any other metallic structures connected to the wellbore or surface equipment, as the conduit for bi-directional data transmission .
  • Providing access to real time pressure and temperature data enables decisions to be made regarding perforating/stimulation strategy and intervention, workover and field development planning.
  • Single or multiple strings can be positioned in a single well in series , allowing many formations to be monitored individually without breaching tubing integrity. Equally, strings may be positioned in different bores holes to allow inter-zone activity monitoring.
  • the firing mechanism described is pressure activated, as an alternative, a wireless receiver and trigger device could be used.
  • the string of monitoring units could be used in conjunction with a tubing barrier and sliding sleeve in order to selectively fracture/stimulate zones .
  • the unit can be used in conjunction with other downhole completions equipment that can be activated hydraulically, mechanically or by electromagnetic signals in order to shut off the tubing below a zone of interest , open up a flow path to that zone, shut off the zone on completion of activities , and subsequently re-open the tubing path.
