Drilling Survey Management: Strategies for… | Helmerich & Payne, Inc.

Drilling surveys are a critical component in the exploration and production of oil and gas resources. It encompasses the techniques and processes used to measure the trajectory of a wellbore, the narrow shaft drilled into the earth. Accurate wellbore surveys are necessary for ensuring that the drilling process adheres to the planned path, which maximizes hydrocarbon recovery and minimizes risks associated with drilling.

Wellbore placement is a strategic operation that involves positioning the wellbore within a specific segment of the reservoir to optimize production. This requires a thorough understanding of the subsurface environment, which is informed by geological and geophysical data. The data collected during wellbore surveying are vital for making real-time decisions about drilling direction and for subsequent well planning and development.

In the oil and gas industry, precision in drilling and well placement directly correlates with economic efficiency and safety. Advancements in survey technology and methodology continue to enhance the accuracy of wellbore positioning. The integration of real-time data with sophisticated software allows for precise control over the well trajectory, reducing uncertainties and the potential for non-productive time (NPT).

Fundamentals of Survey Management

Survey management is a critical process in the exploration and production of oil and gas. It involves the collection, analysis, and application of data to guide the drilling of wellbores in a manner that optimizes resource extraction while ensuring accuracy and safety.

Data Collection: The initial step in drilling surveys is the acquisition of precise data. This includes parameters such as:

Directional data: The azimuth and inclination of the well path.
Tool-face orientation: The orientation of downhole tools in relation to the high side of the borehole.
Location data: The geographical positioning of the wellhead and the subsequent path of the wellbore.
To maintain accuracy, frequent measurements are taken using tools like Magnetic Directional Sensors and Gyroscopic Sensors.

Data Analysis: Survey data are then analyzed to:

Assess the current trajectory of the drill bit.
Compare the actual path to the planned trajectory.
Make necessary corrections to keep the wellbore on course.
Analysis is done using various software tools that can visualize complex data sets and predict the well path using advanced algorithms.

Survey Management Tools: To ensure precision and efficiency, specialized survey management tools are utilized, such as:

Measurement While Drilling (MWD) systems: For real-time data transmission.
Risk Mitigation: An integral part of survey management is the identification and mitigation of risks, which include:

Collision avoidance: Ensuring the new wellbore does not intersect with existing wells.
Wellbore stability: Avoiding trajectories that may cause instability in the surrounding formations.
Documentation: Finally, all survey activities must be documented accurately to provide a clear record for future reference and regulatory compliance.
