Description
Product Overview
Land drilling rigs are the most common type of drilling platform, designed for onshore oil and gas exploration and production. They are widely used in regions with rich shallow to medium-depth hydrocarbon reserves, where equipment can access reservoirs without the challenges of offshore operations.
A typical land rig consists of a derrick, drill string, mud circulation system, and work floor. Compared to offshore rigs, these units are easier to transport, maintain, and relocate. Their lower installation cost makes them the preferred choice for projects in Texas, the Middle East, Central Asia, and other onshore resource-rich regions.
