  1. API 16TR2 now 16TR1June 2017 • Shear Ram Performance Test Protocol • Update

  2. API 16TR1 Scope • This document outlines the standardized test protocol, including data and reporting requirements, for performing a BOP shear ram performance test • Measure the BOP operator force required to shear drill pipe and tubing. • Measure the BOP operator force required to seal after a shear. • The objective of this protocol is to standardize the execution of shear testing and recording of data related to the test. 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  3. API 16TR1 History • Developed a protocol under IOGP with 9 drilling contractor’s and operator’s company shear test procedures • Stress Engineering put together final procedure working with the Task Group • Protocol was put into API format (16TR2) and released for Comment Ballot in April 2016 • Comment Ballot closed June 2016 • Addressed all comments and redrafted protocol – sent to API June 2017 (16TR1) 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  4. API 16TR1 History • API 1st Ballot results: 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  5. API 16TR1 History • Comment Ballot received 304 comments • Duplicate comments: 83 • Total original comments: 221 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  6. API 16TR1 New Addition • Protocol to shear AND seal • Document required shear force • Document required seal force • Achieved by three shears: • Test 1 - Shear with full RWP of hydraulic system, pressure test • Test 2 - Regulate hydraulic pressure back to the shear pressure of the first test (plus 5%), pressure test.  If a seal is not successful, adjust hydraulic pressure by +200 psi increments until seal is achieved. • Test 3 – Regulate hydraulic pressure to the highest of the two previous shears (plus 5%), pressure test.  If a seal is not successful, adjust hydraulic pressure by +200 psi increments until seal is achieved. 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  7. API 16TR1 Path Forward • Document submitted to API June 2017 • 6 week Comment Ballot • Address comments and revise if necessary • Goal to send to API for publication 4Q17 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org
