Examples
-
Convert 5 psi/1000 feet: 5 × 0.0013333333 = 0.0066666665 oz/in³.
-
Convert 10 psi/1000 feet: 10 × 0.0013333333 = 0.013333333 oz/in³.
Common Use Cases
-
Reporting mud weight or hydrostatic pressure gradients in drilling.
-
Estimating pore pressure and fracture gradient during well planning.
-
Specifying densities of materials like metals and plastics in manufacturing drawings.
-
Converting pressure gradient values to standard density units for engineering calculations.
-
Calculating mass from volume and density in U.S. customary units.
Tips & Best Practices
-
Ensure input values are accurate and reflect correct pressure gradients.
-
Use this conversion to align petroleum-related data with manufacturing density units.
-
Understand the context of fluid properties when interpreting conversion results.
-
Apply consistent unit definitions and consider environmental conditions if necessary.
-
When working internationally, consider further unit conversions beyond oz/in³.
Limitations
-
Conversion assumes standard gravity with no temperature or pressure adjustments.
-
Psi/1000 feet is a derived pressure gradient, so density equivalence depends on fluid context.
-
Ounce per cubic inch is mainly for U.S. customary systems and may not suit international workflows.
Frequently Asked Questions
-
What does psi/1000 feet measure?
-
Psi/1000 feet measures the pressure gradient, indicating the change in pressure per 1000 feet of vertical depth, and relates directly to fluid or mud density.
-
Why convert psi/1000 feet to ounce per cubic inch?
-
Converting psi/1000 feet to ounce per cubic inch allows translation of hydrostatic pressure gradients into density units commonly used in U.S. manufacturing and material specifications.
-
Where is ounce per cubic inch commonly used?
-
Ounce per cubic inch is typically used in U.S. engineering and manufacturing to specify material densities, especially for metals, plastics, and foams.
Key Terminology
-
psi/1000 feet
-
A pressure gradient unit expressing how pressure changes per thousand feet of vertical depth, used to infer fluid density in petroleum and wellbore engineering.
-
ounce per cubic inch (oz/in³)
-
A density unit indicating mass in ounces contained within each cubic inch of a material, commonly used in U.S. engineering and manufacturing.
-
hydrostatic pressure gradient
-
The rate of pressure increase with depth in a fluid column, related to the fluid's density and gravitational force.
