NTL 2012-N01 - Calculating Maximum Anticipated Surface Pressure and Expected Surface Pressure for the Completion Case and Estimated Shut-in Tubing Pressure Prior to Production - February 14, 2012

The purpose of this NTL is to clarify the definitions of the maximum anticipated surface pressure for the completion case (MASPcc), expected surface pressure for the completion case (ESPcc), and the estimated shut-in tubing pressure (SITP) prior to actual production.  This NTL also establishes the conditions when you may use an oil gradient and when you must use a gas gradient to calculate the MASPcc, ESPcc, and the estimated SITP.
