Vigor Gyro while Drilling (Wireline)

Gyro while Drilling (GWD) via wireline involves lowering a gyroscopic survey tool through the drill string to the bit, providing real-time, high-accuracy inclination and azimuth data.

Unlike magnetic tools, it operates independently of magnetic interference from casing or adjacent wells. It is primarily used during top-hole drilling, sidetracking, or in high-congestion areas, providing precise positioning.

Overview of Gyro while drilling

Gyro while drilling, also known as gyroscopic surveying or gyroscopic drilling, is a technique used in the oil and gas industry for accurate wellbore positioning and directional drilling. It involves the use of a gyroscope tool to measure the inclination, azimuth, and toolface of a wellbore.

Here's how Gyro while drilling drilling works:

1.Gyroscope Tool: A gyroscopic tool is used, which contains a spinning gyroscope that maintains a fixed direction in space. It remains aligned with the Earth's true north, regardless of the wellbore's orientation.

2.Running the Tool: The gyroscopic tool is run into the wellbore on the bottom of the drillstring. It can be run independently or as part of a bottomhole assembly (BHA) that includes other tools such as mud motors or rotary steerable systems.

3.Gyroscopic Measurement: As the tool rotates with the drillstring, the gyroscope maintains its orientation. By measuring the precession (change in orientation) of the gyroscope, the tool can determine the wellbore's inclination (angle from vertical) and azimuth (horizontal direction).

4. Surveying Intervals: To gather data along the wellbore, the drillstring is periodically stopped, and the gyroscope measurement is taken at specific survey intervals. These intervals can range from a few feet to several hundred feet, depending on the requirements of the well plan.

5.Calculating Wellbore Position: Using the measurements from the gyroscopic tool, the data is processed to calculate the wellbore's position, which includes its XYZ coordinates (latitude, longitude, and depth) relative to a reference point.

6.Wellbore Trajectory: The collected survey data allows for the construction of the wellbore's trajectory or path. By connecting the surveyed points, operators can determine the wellbore's shape, curvature, and direction.

7.Steering and Correction: The trajectory data is used by drilling engineers to steer the wellbore in the desired direction. Corrections can be made in real-time using measurement-while-drilling (MWD) or logging-while-drilling (LWD) tools to adjust the drilling path and maintain accuracy.

Gyro drilling is particularly useful in complex drilling scenarios, such as directional drilling, horizontal drilling, or drilling in offshore environments. It helps operators maintain wellbore placement within the target reservoir and avoid drilling into undesirable areas or neighboring wells. Accurate wellbore positioning is crucial for maximizing hydrocarbon recovery, optimizing drilling efficiency, and reducing drilling risks.

Vigor's gyroscope series products include a variety of different product types to meet a variety of complex well conditions. The biggest difference between Vigor's gyroscope inclinometer and other gyroscopes is its high durability and reliability, which has been proven at the customer's site. Vigor's gyroscope inclinometer is easy to assemble, disassemble and use, and requires only minimal training to become a skilled worker. At the same time, Vigor can also provide you with gyroscope international field measurement services, if you are interested in Vigor's gyroscope inclinometer and other logging and completion tools, please do not hesitate to get in touch with us, you will definitely get the answer you need in Vigor.
