Directional Drilling - A Step in the Right Direction

Directional Drilling

A Step in the Right Direction

Directional Wells

• Horizontal – Short Radius– Medium Radius– Long Radius

• Slant– Straight, but at a predetermined angle

• Deviated– “S” Curve

Single Wells-Multilateral Wells

Slim Hole Mud Motor with Bent Sub

Monel Drill Collars

MWD Tools

Self-contained Wire Line Unit

MWD - “Measurement While Drilling”

• Real time directional surveys

• Rotational speed of the drillstring

• Mud flow volume

• Downhole temperature

• Torque and Weight on Bit

LWD - ”Logging While Drilling”

• Measures– Formation density– Porosity– Resisitivity– Inclination at the Drill Bit– Magnetic Resonance– Formation Pressure

Horizontal Wellbore

Advantages

• Multiple wellheads on single pad

• Less surface and environmental disturbance

• Less roads and ROWs to maintain

• Drilling and production waste centralized to one site

• Centralization of facilities

• Lower operating costs

Three wells - All directional to the same formation

Four wells - One straight well and three directional wells - Same formation
