daily drilling report造句

• This chronology is built from daily drilling reports and well-site reports and is the first to highlight and document the numerous inconsistencies between papers and reports.
• These include the claims that losses occurred seven minutes after the earthquake ( when drilling data actually suggests losses preceded the earthquake ); that losses at total depth occurred immediately after major aftershocks ( whereas total losses occurred over 1.5 hours after any aftershocks ); that losses at total depth were cured ( whereas there are multiple reports of ongoing losses over an 18-hour period whilst pulling out of hole ); that the drilling kick was killed within 3 hours ( whereas drill pipe pressures fluctuate repeatedly for 24 hours after kick, indicating ongoing cycles of downhole influx and losses ); that there is no evidence for downhole losses ( that would indicate fracturing or fault reactivation ) during the drilling kick ( yet mud engineer reports state that over 300 barrels of drilling mud was lost downhole during the kick ) and; that there was no connection between the mud flow and wellbore ( yet the daily drilling reports state that mud flow activity noticeably decreased when dense drilling mud was pumped down the well during attempts to stop the mudflow ).
