Downhole to surface data lift apparatus

Abstract

Data may be collected from a wellbore by retrievably deploying a data receiver tool to a location proximate a gauge located in the wellbore, where the gauge comprises a sensor used to collect data from the well and where the location is at a distance sufficient to allow wireless data communication between a first wireless data transceiver and a gauge wireless data transceiver; securing the data receiver tool at that location; transmitting data from the gauge memory to the data receiver tool; and storing the transmitted data in the data receiver tool writeable memory.

Description

FIELD OF THE INVENTION

The disclosed invention related to data acquisition within a wellbore.

BACKGROUND

Data acquisition in a well during production and drilling is known in the art. In the production sector of the exploration and production of hydrocarbons, downhole gauges for production and reservoir evaluation are used with permanent and retrievable systems. The retrievable systems are normally deployed inside production tubing using an electrical cable that transmits information from the well in real time to the surface as the system is pulled from the bottom of the well to the surface, logging the entire well for data.

Permanently and semi-permanently deployed gauges are also used in the wellbore. Permanent gauges use a cable mounted on the outside of the production tubing from the surface to where the gauge is located inside of the well. The gauges transmit data in real time continuously. If the cable is cut, the gauge is no longer connected to the surface and no data are transferred to the surface. Cable deployment is also very complicated and can cause the customer to have to go in the well to fish the system if the cable is not flush to the production tubing. Semi-permanent gauges exist where the semi-permanent gauge seats in a side pocket mandrel inside the well, collects data, and stores the data in memory. When the operator wants data the gauge must be retrieved from the well, typically with specialty equipment to retrieve and install the gauge. There is a potential for the gauge to fall from the retrieval equipment and go to the bottom of the well. Also, the gauge may not come out of the side pocket gauge.

Some systems exist where the gauge does not need to be retrieved from a downhole location where the systems do not use downhole cables. These systems may utilize devices deployed with the use of an electric line or slick line downhole to retrieve desired data from the gauge.

Gauge power supply 234 may comprise a downhole power generator, a battery, a rechargeable battery, or a rechargeable super capacitor.

In the operation of exemplary embodiments, data may be collected from wellbore 101 using data receiver tool 10, as described above, by deploying gauge 50 in well 100, where gauge 50 is as described above, and using one or more sensors 233 to collect data from well 100. The collected data are typically stored in the gauge's writeable memory. Gauge 50 may be deployed permanently or semi-permanently within wellbore 101. In embodiments, gauge 50 may be deployed in well 100 by deploying gauge 50 as part of the casing, liner or production tubing.

At a desired time, data receiver tool 10 is deployed into wellbore 101 and positioner 40 used to maneuver data receiver tool 10 to a location proximate gauge 50 sufficient to allow wireless data communication between first wireless data transceiver 31 and gauge wireless data transceiver 231. Using positioner 40 typically comprises allowing data receiver tool 10 to travel in wellbore 101 such as by using gravity and using catcher assembly 43, which is deployed at a predetermined distance in wellbore 101 such as a location just or somewhat below gauge 50, to stop the travel of data receiver tool 10. In certain embodiments, data receiver tool 10 travels in wellbore 101 to a position within or at least partially within an interior of gauge 50.

Once sufficiently close, data are transmitted from gauge 50 to data receiver tool 10, by way of example and not limitation including gathering data from memory associated with gauge data collector 232 and transmitting that data. Transmitted data, once received by data receiver tool 10, are typically stored in memory associated with data collector 32.

In certain embodiments, transmitting data from gauge memory to data receiver tool 10 may comprise detecting when data receiver tool 10 is located a predetermined distance from the gauge; sending a send data command message to gauge 50 such as from data receiver tool 10 that data receiver tool 10 is ready to receive data; and transmitting the data from gauge 50 to data receiver tool 10 after gauge 50 has received the send data command message.

It may be advantageous to retrieve data receiver tool 10 from wellbore 101 at a predetermined time. In embodiments, once data receiver tool 10 is determined to have completed the data transfer due to a calculation at surface 103 on the time required to transfer the data, fluid flow rate of well 100 may be increased to release data receiver tool 10 from catcher assembly 43 and be sent to a further location. By way of example and not limitation, once released fluid flow within well 100 may carry data receiver tool 10 back to the surface.

It is understood that, as used herein, wireless may comprise using electromagnetic waves and/or acoustic waves.
