Bottom Hole Pressure app for iPhone and iPad

FEATURES
•Calculates bottom hole pressure (BHP) also known as hydrostatic head or hydrostatic pressure
•Displays normal ranges for density and depths for easy reference
•Supports US and Metric units

INPUTS
•Fluid Density (lb/gal or kg/m^3)
•True Vertical Depth (ft or m)

OUTPUT
•Bottom Hole Pressure (psi or kPa)

METHODOLOGY
Bottom hole pressure is calculated based on contributions of all fluids (spacers, weighted pills, etc) in the annulus. To calculate bottom hole pressures, BHP utilizes the standard equation for bottom hole pressure found in API Recommended Practice 10B-2 Second Edition, April 2013:

US Units (Customary)
•BHP(psi) = 0.052 x Fluid Density (lb/gal) x True Vertical Depth (ft)

Metric Units (SI)
•BHP(psi) = 0.00981 x Fluid Density (kg/m^3) x True Vertical Depth (m)

FEEDBACK
As awesome as we think we are, we know we’re not perfect. What you have is our first attempt to address what we perceived the core needs of our target audience to be. As you begin to integrate this app into your work life we expect errors, short-comings and worthwhile enhancements to become apparent.

While we welcome praise, we find constructive (and respectful) criticism to be of more value. Please don’t hesitate to send us thoughts, comments and questions on any of our products or new products you would like to see. [email protected]
