A series of reference guides for safe and efficient drilling operations, compiled by drilling industry professionals.

Drilling rigs situated on land, often with permanent or temporary structures.

Drilling rigs tailored for specific environments such as deserts or Arctic regions.

Drilling rigs designed to move from one well site to another, frequently used in multi-well locations.

Drilling rigs operating in marine environments, categorized by water depth and support structure.

Offshore rigs situated on large, bottom-supported structures (jackets) in relatively shallow water.

Offshore rigs categorized by water depth, differing in stationkeeping systems and hull configurations.

MODUs operating in relatively shallow water depths.

MODUs operating in intermediate water depths, primarily using traditional mooring systems.

MODUs operating in deeper water depths, often utilizing dynamic positioning systems.

MODUs operating in the deepest water depths, exclusively utilizing dynamic positioning.

Floating rigs with large deck space and dynamic positioning capability suitable for deepwater drilling.

System of thrusters on a floating rig to maintain position over a well.

Rigs supported by legs that can be raised and lowered independently, typically used in shallow to moderate water depths.

Elevated structures above submersible barges, suitable for shallow water well drilling.

Purpose-built rigs resting on the ocean floor, suitable for shallow water drilling.

Critical equipment at the wellhead used for well control during drilling operations.

A gradual change in the direction of a wellbore, measured in degrees per 100 feet.

The weakening of a material due to repeated stress, often caused by drilling in a dogleg.

The stress level at which a material starts to deform permanently.

A measure of the resistance to flow of drilling fluid, considering the presence of solids.

The percentage of the total fatigue life of drill pipe that has been used up due to stress cycles.

The deterioration of a material due to chemical reactions.

Doglegs create stress cycles on drill pipe, causing fatigue and reducing its lifespan. The severity of this effect depends on the dogleg's sharpness and drilling conditions.

Both are pinned to the ocean floor at their corners.

Both rigs are primarily used for exploratory drilling, typically drilling only one well at a specific location.

A rig supported by legs that can be raised and lowered, typically used in shallow to moderate water depths.

The hull of the jackup is lifted out of the water by a jacking mechanism, typically using pinion drives or hydraulic cylinders, to achieve an air gap above storm waves.

The distance between the mean water level and the bottom of a jackup's hull.

The air gap protects the jackup from storm waves, ensuring the integrity of the rig during rough weather.

The diameter of drillpipe has increased from 5 inches to 5 ½ inches and even 6 ⅝ inches to accommodate ultra-deepwater wells.

Drillpipe joint lengths have increased from 50 feet to 75 feet or longer to reduce the number of connections and save time.

Drillpipe is categorized into API Ranges based on length. API Range 2 (27-30 ft) is common, but some drillers use API Range 3 (38-45 ft) to further reduce NPT.

Instead of pulling single drillpipe joints up the V-door, entire stands of multiple pipes are assembled separately to increase efficiency.

Ultra-deepwater wells require higher hydrostatic pressures, leading to a shift from straight hydraulic BOP controls to multiplex (electronic) control systems.

Using thrusters on a semi-submersible rig to help it move into position and reduce load on moorings.

The maximum weight a rig can safely carry on its deck. Important for drilling in deeper waters.

Drillships designed for deepwater drilling, equipped with dynamic positioning systems to maintain position.

A traditional mooring system for rigs, using eight anchor points to hold them in place.

Traditional mooring systems are not practical in deepwater due to the challenges of long, heavy mooring lines. DP systems offer a more efficient and safe solution.

DP systems use GPS and acoustic systems to determine the rig's position and use thrusters to adjust its position in real-time.

DP systems allow for faster re-positioning of the rig, are more flexible in changing weather conditions, and reduce the environmental impact of mooring lines.

From traditional 8-point moorings to dynamic positioning systems, drillships have become more sophisticated and capable of operating in deeper waters.

Semisubmersibles can turn into the weather, reducing their motions and improving performance compared to drillships with traditional mooring.

A type of jackup rig that utilizes a large, flat platform (mat) to distribute the weight over a wider area of the seabed, increasing stability in soft soil conditions.

A jackup rig with individual legs that can be raised and lowered independently. They are typically used in areas with firmer seabed conditions.

The vertical distance between the ocean floor and the drilling deck of a jackup rig. This is critical for drilling operations and safety, especially in rough weather.

A procedure performed on jackup rigs before drilling to simulate maximum loading conditions and ensure stability. This involves filling tanks with seawater to push the legs into the seabed.

An older type of jackup with a fixed slot on the hull, limiting drilling to only one well per location.

Some early jackups with small air gaps were sheared off their legs during storms due to insufficient vertical clearance and stability. Jackups with larger air gaps experienced significantly less damage.

The preload sequence helps to simulate the worst-case loading conditions that a jackup rig might encounter during its operation, ensuring that the legs are properly anchored and the platform is stable.

A mat-supported jackup distributes weight over a larger area of the seabed through its large, flat mat, making it better suited for softer ground. An independent-leg jackup utilizes individual legs, offering more flexibility in firmer seabed conditions.

A larger air gap provides more vertical clearance for the jackup, increasing its stability and allowing it to withstand harsher weather conditions. It also allows for greater flexibility in drilling operations.

The slot in older slot-type jackups limited the rig to drilling only one well from a single location, significantly impacting drilling flexibility and efficiency.
