Bottom Hole Temperature
Detailed App Info:
Application Description
FEATURES
•Predicts bottom hole static temperature (BHST)
•Predicts bottom hole circulating temperature (BHCT)
•Depths ranging from 1,000 ft - 22,000 ft
•Calculations utilize methodologies and data found in API Recommended Practice 10B-2 Second Edition, April 2013.
INPUTS
•True Vertical Depth (1,000 ft - 22,000 ft)
•Measured Depth (≥ True Vertical Depth ft)
•Temperature Gradient (0.7 - 1.9 °F/100 ft )
OUTPUTS
•Bottom Hole Static Temperature (°F)
•Bottom Hole Circulating Temperature (°F)
*Currently, this application only supports US Customary units.
METHODOLOGY
The tables in Annex D of API RP 10B-2 are a matrix of predicted circulating temperatures for the following well simulation schedules as a function of true vertical depth and temperature gradient.
•Casing
•Liner
•Squeeze
Temperature predictions are given for true vertical depths ranging from 1,000 ft to 22,000 ft and temperature gradients ranging from 0.9 to 1.9.
To predict bottom hole temperatures, BHT utilizes a standard regression technique. This technique, when used in combination with cited tables in API RP 10B-2 Annex D, allows BHT to predict bottom hole temperatures for any depth-gradient input combination that fall within the bounds of relevant tables.
Smaller temperature gradients than those listed in Annex D have been extrapolated from 0.9 °F/100 ft down to 0.7 °F/100 ft in response to a customer request. Temperature predictions for this gradient range utilize the same regression technique referenced to above.
If the user-defined measured depth value is greater than true vertical depth by 1,000 ft or more, the well is assumed to be highly deviated, lateral, or horizontal and the predicted bottom hole circulation temperature is set equivalent to the bottom hole static temperature value.
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. founders@threeedev.com
