Define: Deviation-Well Survey

A deviation well survey is a process used in the oil and gas industry to measure the direction and angle of a wellbore. It helps determine the well’s position and trajectory, ensuring accurate drilling and extraction operations.

A deviation well survey is crucial for several reasons. It ensures compliance with drilling regulations, helps prevent well collisions, aids in accurate well placement, and assists in optimizing production and reservoir management.

The responsibility for conducting a deviation well survey typically lies with the drilling operator or the company overseeing the drilling operations. They may hire specialized surveying companies or have in-house surveying teams to perform the task.

Yes, there are legal requirements for conducting a deviation well survey. These requirements vary by jurisdiction but generally involve obtaining permits, adhering to safety regulations, and submitting survey reports to regulatory authorities.

Yes, a deviation well survey can be challenged legally if there are concerns about its accuracy or compliance with regulations. Parties affected by the survey, such as neighboring landowners or competing drilling operators, may seek legal recourse to address any potential issues.

If a deviation well survey reveals non-compliance with drilling regulations, the drilling operator may face penalties or fines imposed by regulatory authorities. They may also be required to rectify the non-compliance and bring the well into compliance with the applicable regulations.

Yes, a deviation well survey can be used as evidence in legal disputes. It can help establish the position and trajectory of a wellbore, which may be relevant in cases involving property rights, well interference, or contractual disputes.

The frequency of conducting a deviation well survey depends on various factors, including regulatory requirements, drilling operations, and well complexity. Generally, surveys are conducted at regular intervals during drilling and completion stages and may be repeated periodically during the well’s lifespan.

A surveyor conducting a deviation well survey should have relevant qualifications and experience in wellbore surveying techniques. They should be familiar with industry standards, possess knowledge of drilling operations, and be proficient in using surveying equipment and software.

Yes, a deviation well survey can be used to determine liability in case of accidents or environmental damage. By accurately determining the well’s position and trajectory, it can help establish whether the wellbore contributed to the incident and aid in determining responsibility and potential compensation.
