BAKER HUGHES - Drilling Fluids Reference Manual

Baker Hughes Drilling Fluids
Using these screening parameters will yield a designed drill-in fluid that will create a filter cake which
will mechanically seal off all pore openings exposed to the well bore, remain intact during the
completion phase, and be easily removed for the production (or injection) of oil and/or gas.
The Proposed Drill-In and Completion Program
Prior to testing and recommending a drill-in fluid, fundamental details about an operator’s reservoir
must be known. Recording information on the items listed below will assist those involved to decide
what application exists and which fluid should be selected for that application.
Local Environmental Regulations
Reservoir Characteristics
Reservoir fluid composition (oil, gas, or formation water)
Lithology (sandstone, limestone, etc.)
Cementation (consolidated, unconsolidated, fractured)
Quantity and type of clays present
Operator Recommendation/Plan
Slim or large hole
Completion technique (gravel pack, non-gravel pack)
Hole geometry (horizontal, vertical, or high-angle)
Note:
To learn more about the effects of a drill-in fluid on a particular type of completion, refer to
the Baker Hughes Drilling Fluids Drill-In Fluids Manual
As previously listed, the drill-in fluid must be subjected to the following testing to ensure adequate
protection of a producing reservoir.
