Memory casing collar locator-gamma ray tool carrier for coiled tubing applications
Apparatus and method for a carrier sub for a coiled tubing in a well including an outer housing coupled to the coiled tubing, an inner housing disposed inside the outer housing defining an annulus between the inner and outer housing, and a sensor tool including a casing collar locator and a gamma ray tool inserted into the inner housing. The sensor tool is removable from the inner housing and is integrated with a memory system within the casing collar locator and the gamma ray tool for data storage of data measured by the casing collar locator and the gamma ray tool. The carrier sub further includes at least two flow ports in the inner housing to direct fluid flow out of the inner housing, into the annulus, and toward an exit of the carrier sub. The sensor tool is isolated from fluid communication with the well.
1 . A carrier sub for a coiled tubing in a well comprising:
an outer housing coupled to the coiled tubing;
an inner housing disposed inside the outer housing defining an annulus between the inner housing and the outer housing;
a sensor tool comprising a casing collar locator and a gamma ray tool inserted into the inner housing of the carrier sub, the sensor tool configured to be removable from the inner housing,
wherein the sensor tool is integrated with a memory system within the casing collar locator and the gamma ray tool for data storage of data measured by the casing collar locator and the gamma ray tool; and
at least two flow ports disposed in the inner housing configured to direct fluid flow out of the inner housing, into the annulus of the carrier sub, and toward an exit of the carrier sub,
wherein the sensor tool is isolated from fluid communication with the well, via the at least two flow ports.
2 . The carrier sub of claim 1 , further comprising:
a first threaded connection disposed at a first end of the sensor tool and a second threaded connection of the sensor tool disposed at a second end of the sensor tool configured to hold the sensor tool in place in the inner housing,
wherein the sensor tool is configured to be inserted and removed within the inner housing by screwing and unscrewing the first threaded connection or the second threaded connection.
3 . The carrier sub of claim 2 , wherein the first threaded connection is an inner threaded connection and the second threaded connection is an outer threaded connection.
4 . The carrier sub of claim 2 , wherein the first threaded connection and the second threaded connection comprise a seal.
5 . The carrier sub of claim 1 , wherein the at least two flow ports each comprise a flow nozzle.
6 . The carrier sub of claim 1 , further comprising:
a first end of the carrier sub comprising a third threaded connection to couple to a first tool joint of the coiled tubing.
7 . The carrier sub of claim 6 , further comprising:
a second end of the carrier sub comprising a fourth threaded connection to hold the sensor tool in place and be coupled to a second tool joint of the coiled tubing.
8 . The carrier sub of claim 7 , wherein the fourth threaded connection is slimmer than the third threaded connection.
9 . The carrier sub of claim 1 , wherein fluid flow is continuous through the carrier sub.
10 . A method for carrying a sensor tool in a coiled tubing in a well, the method comprising:
inserting the sensor tool comprising a casing collar locator and a gamma ray tool into an inner housing of a carrier sub;
running the carrier sub with the coiled tubing into the well, wherein the carrier sub comprises an outer housing and the inner housing disposed inside the outer housing defining an annulus between the inner housing and the outer housing;
measuring data, via the casing collar locator and the gamma ray tool;
storing measured data, via an integrated memory system within the casing collar locator and the gamma ray tool;
directing fluid flow, via at least two ports disposed in the inner housing, out of the inner housing, into the annulus of the carrier sub, and toward an exit of the carrier sub; and
isolating the sensor tool from fluid communication with the well by directing fluid flow via the at least two ports.
11 . The method of claim 10 , further comprising:
securing the sensor tool in place in the inner housing via a first threaded connection disposed at a first end of the sensor tool and a second threaded connection of the sensor tool disposed at a second end of the sensor tool; and
removing the sensor tool from within the inner housing by unscrewing the first threaded connection or the second threaded connection,
wherein inserting the sensor tool comprises screwing the first threaded connection or the second threaded connection.
12 . The method of claim 11 , wherein the first threaded connection is an inner threaded connection and the second threaded connection is an outer threaded connection.
13 . The method of claim 11 , wherein securing the sensor tool comprises sealing the first threaded connection and the second threaded connection using a seal.
14 . The method of claim 10 , wherein directing fluid flow comprises directing fluid flow via a flow nozzle.
15 . The method of claim 10 , further comprising:
coupling a first tool joint of the coiled tubing, via a third threaded connection, to a first end of the carrier sub.
16 . The method of claim 15 , further comprising:
coupling a second tool joint of the coiled tubing and securing the sensor tool, via a fourth threaded connection, to a second end of the carrier sub.
17 . The method of claim 16 , wherein the fourth threaded connection is slimmer than the third threaded connection.
18 . The method of claim 10 , wherein directing fluid flow comprises continuous fluid flow through the carrier sub.
