LiDAR TOOL FOR OIL AND GAS WELLBORE DATA ACQUISITION
In one example, an apparatus includes a TLT (Time of Flight (TOF)/LiDAR tool) with one or more optical transmitters and optical receivers that are operable to cooperate to obtain data concerning a downhole feature when the apparatus is deployed in a downhole environment. This apparatus further includes a first device operable to determine a position, speed, and/or orientation, of the TLT, when the TLT is deployed in the downhole environment, a second device configured to store locally and/or transmit the data to a location on a surface, a power source connected to the TLT, the first device, and the second device, and a housing within which the TLT, first device, second device, and power source are disposed, and the housing includes a connector configured to interface with a piece of downhole equipment.
1 . A method, comprising:
deploying a Time of Flight (TOF)/LiDAR tool including a LiDAR module to a downhole location; and
using the LiDAR module to perform operations comprising:
detecting a downhole feature;
gathering data concerning the downhole feature; and
transmitting the data.
2 . The method as recited in claim 1 , wherein the operations further comprise storing the data, and processing the data.
3 . The method as recited in claim 1 , wherein the operations further comprise mapping, or facilitating mapping of, the downhole feature using the data.
4 . The method as recited in claim 1 , wherein the operations further comprise perforating a well casing, and the downhole feature comprises a perforation in the well casing.
5 . The method as recited in claim 4 , wherein the perforating is performed as the Time of Flight (TOF)/LiDAR tool is being lowered down the downhole location.
6 . The method as recited in claim 1 , wherein the gathering of the data is performed as the Time of Flight (TOF)/LiDAR tool is being retracted from the downhole location.
7 . The method as recited in claim 1 , wherein the method is performed as part of a frac preparation phase for a well and/or surveillance of a disposal/injection well.
8 . A method, comprising:
deploying a Time of Flight (TOF)/LiDAR tool including a LiDAR module within a component and/or at an exterior portion of the component, wherein the component is located on the surface rather than in a downhole location; and
using the LiDAR module to perform operations comprising:
detecting a component feature;
gathering data concerning the component feature; and
transmitting the data.
9 . The method as recited in claim 8 , wherein the component feature comprises one or more of threads, and thread connections.
10 . The method as recited in claim 8 , wherein the component comprises a bottom hole assembly.
11 . The method as recited in claim 8 , wherein the data comprises data about any one or more of: a perforation location; a perforation orientation; a perforation diameter; a penetration depth of a perforation; a casing wall deformity; a collar location; a deviation in a case wall; a casing wall leak; a flow rate through a perforation; a temperature of a perforation; and, an inside diameter of a casing.
12 . The method as recited in claim 8 , wherein deploying a Time of Flight (TOF)/LiDAR tool comprises pumping the Time of Flight (TOF)/LiDAR tool down to the downhole location.
13 . The method as recited in claim 8 , wherein the LiDAR module operates to map an entire wellbore that includes the downhole location.
14 . A method, comprising:
deploying a Time of Flight tool in a downhole environment that includes one or more down hole features;
determining, while the Time of Flight tool is in the downhole environment, a position, speed, and/or orientation, of the Time of Flight tool;
transmitting, with the Time of Flight tool, a first signal;
receiving, with the Time of Flight tool, a second signal that results from transmission of the first signal;
using information from the first signal and the second signal to obtain data concerning one of the downhole features; and
storing the data locally and/or transmitting the data to a surface location.
15 . The method as recited in claim 14 , wherein the first signal is transmitted by an optical signal transmitter, and the second signal is received by an optical signal receiver.
16 . The method as recited in claim 14 , wherein the first signal is transmitted by an acoustic signal transmitter, and the second signal is received by an acoustic signal receiver.
17 . The method as recited in claim 14 , wherein the first signal is transmitted by an electromagnetic signal transmitter, and the second signal is received by an electromagnetic signal receiver.
18 . The method as recited in claim 14 , further comprising detecting, and reporting on, a condition within the downhole environment.
19 . The method as recited in claim 14 , wherein the second signal is a backscatter signal.
