vertical well continuous gyro completed the first uphole test at the customer's site
From July 1 to 12, 2024, the vertical well continuous gyro completed the first uphole test at the customer's site.
This project is designed for 37 main wells and 33 other observation wells, with a design depth of 720 meters, most of the wells are built at a distance of only 1.3 meters, which makes it difficult to control the trajectory of the boreholes, and requires very high accuracy of the gyro instrument.
In more than 10 days, the gyro has completed 7 well measurements, accumulated more than 70 times into the well, the slanting trajectory is accurate and reliable, fully verified the tool's measurement accuracy and reliability.
The following is the horizontal projection of the measurement data of two wells, and the position repeatability error is <0.3‰ (0.3 thousandths)!
Gyrofinder will continue to focus on R & D and innovation of gyros tool, constantly challenge higher measurement accuracy, and provide customers with accurate measurement services with better products.

GyroFinder Work on vertical wells
GyroFinder Work on vertical wells
In the begining of 2021,Gyro finder got an requirement for continuous gyro, which will work on vertical wells. And most gyro in the market only can continuous work at INC>6 deg, in this case, the gyro have to be used as single shot that will waste a lot of time.
Gyrofinder provided a continuous gyro in March and this gyro can run fast even when the wells are vertical INC<5 deg. Gyrofinder can update 3 readings per second and record data in every centimeter, this accuracy is very important in cluster wells and exploration data in mining.
Compared with other gyro tools, gyrofinder have the following advantages:
1、North seeking, no need align at surface.
2、 Run continuous at any inclination.
3、Fast Run 150m/min.
4、FOG sensor, more reliable and accurate
In a recent work, Gyrofinder took 40 minutes in a 585 meters well and got 2 complete RUNIN and RUNOUT data, and competitor took 86 mins for one run only as it have to run as single shot for vertical well. Because the winch from customer only can work as speed 50m/min, and gyrofinder can run as max 150m/min, it can save more time if have faster winch available.
The 2 Gyrofinder runs can match with client data, and the error between RUNIN and RUNOUT is about 0.5 meter, accuracy is 0.1%, which is the equivalent of only 1m of uncertainty in a 1000m hole.
