Functions of Drilling Fluids

Remove Cuttings from the wellbore

• Drilling and fluid factors that affect

cuttings removal:

• Cuttings (size, shape and density)

• Rate of penetration

• Drillstring rotation

• Annular velocity

• Drilling fluid rheology (viscosity)

Drilling Fluid Properties Affecting Hole Cleaning

Control Formation Pressure

• Have enough fluid density

to control the influx of

liquids and gas

• Have enough hydrostatic

pressure by a static drilling

or completion fluid column .

Control Formation Pressure

Suspend and Release Cutting

Removal Of Cuttings

Cuttings must

be removed

by the solids

control

equipment.

Fluid Selection

• Well Objectives

– exploration

– producer

– injector

• Interval Objectives

• Inhibition level

– previous well data and hole problems

– geology

• Mud Weights

– frac and pore gradients.

– Previous well data

• Temperatures

• Logistics - Storage

• Environmental/Pollution

• Deepwater, ERD, MPD, UBD, ....

RDF Base Fluid Selection

• XRD for overall mineralogy

• Shale stability for inhibition

requirements

• Select OBM, WBM or WBM with

shale inhibitors

End of Drilling

• Wells can be batch drilled

• Wells can be batch completed

• Depending on the exploratory, this will determine the

completion.

– Side tracking

– P&A

– Dry Hole

– Type of Formation

– Formation Data

Completions

• Once the well is drilled,

in the development

phase, a completion

fluid will be spotted in

place of the drilling

fluid. This aids in

improved production.

Types of Completions

• Case Hole

• Open Hole

Cased Hole Completions

• Cemented and perforated

• Perforated/GP

Open Hole Completions

• Stand Alone Screen

• Gravel Pack

• Barefoot

Reservoir Drill-in Fluids

• Compatible with the formation.

• Limit liquid and solids invasion into the reservoir

• Mitigate Formation Damage

• Be compatible with the completion.

Reservoir Drill-in Fluids and Filter cake Breakers

Filter cake Breakers

• Minimize safety and environmental footprint

• Avoid acid handling at surface

• Reduce hazards associated with spills and preventive measures required
