Description of Events
BP purchases the mineral rights to drill for oil at the Macondo well at the Minerals
Management Service's (MMS) Lease Sale #206, held in New Orleans. The well is
located in Mississippi Canyon Block 252 in the United States sector of the Gulf of
Mexico approx. 41 miles (66 km) off the Louisiana coast.
BP files a 52 page exploration and environmental impact plan for the Macondo well with the MMS. The
plan stated that it was "unlikely that an accidental surface or subsurface oil spill would occur from the
proposed activities".38 In the event an accident did take place the plan stated that due to the well being
48 miles (77 km) from shore and the response capabilities that would be implemented, no significant
The Department of the be expected.
adverse impacts would Interior exempted BP's Gulf of Mexico drilling operation from a detailed
environmental impact study after concluding the unlikelihood of a massive oil spill.
Mark E. Hafle, a senior drilling engineer at BP, warns of the likelihood of collapse of the metal casing for
the blowout preventer under high pressure.
Schlumberger crew arrives on Transocean Marianas to perform logging, measuring, and drilling services
for BP on Mississippi Canyon Block 252 ("MC252") . Specifically, BP, contracted with Schlumberger to
perform logging while drilling, measuring while drilling, and directional drilling services.
The Transocean Marianas semi-submersible rig begins drilling of the Macondo well.
Schlumberger crew performs logging, measuring, and drilling services for BP.
Schlumberger crew departs Transocean Marianas in advance of approaching Hurricane Ida.
Transocean Marianas sustains damage in Hurricane Ida.
Transocean tows Transocean Marianas to shipyard for repairs. Transocean Marianas does not return to
MC252.
Transocean Deepwater Horizon commences activities in MC252. BP contracted with Halliburton to
perform logging while drilling, measuring while drilling, directional drilling services and cementing on
the Transocean Deepwater Horizon. BP contracted with Schlumberger tOPJ ovide wireline oQen and
cased hole services.
Target date for the completion of the well which had been budgeted to cost $96 million
Well flowed at 13,305 feet. Lost circulation. Stuck drill pipe
Schlumberger crew arrives on Transocean Deepwater Horizon to perform a wireline cased hole service
for BP. Specifically, the drilling pipe in the weUbore stuck during drilling. BP requests Schlumberger to
try to determine where the drilling pipe was stuck in the well bore so the drilling pipe above that point
could be removed. performs wireline cased hole logging service to identify free drilling pipe for pipe

retrieval. During the performance of this service, the tool used by Schlumberger becomes lodged and is
abandoned. BP reimburses Schlumberger for the cost of the tool.
Schlumberger crew deports Transocean Deepwater Horizon.
Marvin Volek, a Halliburton employee, warns that BP's use of cement "was against our best practices"
Schlumberger crew orrives on Transocean Deepwater Horizon to perform wireline open hole logging and
testing services for BP. BP informs Schlumberger crew that drilling activities not yet completed and
sends crew home.
MMS issues permit to BP for the well, noting: "Exercise caution while drilling due to indications of
shallow gas and possible water flow."
Schlumberger crew deports Transocean Deepwater Horizon.
Witness stated pieces of rubber returned in mud flow over shakers
Estimated to be from stripping operations during well control event (~1300 ft pipe stripped) Expected
normal wear on lower annular rubber element
Schlumberger crew returns to Transocean Deepwater Horizon to perform wireline open hole logging and
testing services for BP. Specifically, BP contracted with Schlumberger to perform an evaluation of the
formation characteristics for porosity and permeability, and to gather fluid pressures and samples.
BP drills last section with the wellbore 18,360 feet (5,600 m) below sea level but the last 1,192 feet (363
m) needs casing. BP chooses to do a single liner with fewer barriers that is faster to install and cheaper
($7 to $10 million) against Halliburton‟s recommendation of using a liner/ tieback casing that will
provide redundant barriers to flow.
Finish Drilling
9-7/8"x8-1/2" Open Hole
14.0 ppg mud inside and out
Trip out with drilling
Wireline log for 4 days
Annular passed subsequent pressure test on 10 April (250psi/3500psi)
Schlumberger crew performs wireline open hole logging and testing services for BP.
BP drilling engineer Brian Morel, emails a colleague "this has been [a] nightmare well which has
everyone all over the place."
Bp Drilling engineer Brian Morel informs Jesse Gagliano,a Halliburton executive, that they plan to use 6
centralizers for the casing. Gagliano‟s modeling showed that it would require 21 centralizers to achieve
only “MINOR” gas flow problem. Morel„s response in his email was "it's too late to get any more product
on the rig, our only option is to rearrange placement of these centralizers." Gagliano also recommends to
circulate the drilling mud from the bottom of the well all the way up to the surface to remove air pockets
and debris which can contaminate the cement, saying in an email, "at least circulate one bottoms up on
the well before doing a cement job." Despite this recommendation, BP cycles only 261 barrels (41.5 m3)
BP chose fraction a the total mud used in instead
of mud, a to installof single string of casingthe well.of a linear and tieback, applying for an amended
permit on April 15. MMS approves amended permit for BP to use a single liner with fewer barriers on
the same day. crew deports Transocean Deepwater Horizon.
Schlumberger
Run in hole for wiper trip
Circulate bottoms up at TD
Pump high vis sweep
Monitor for gains or losses-none
14.0 ppg mud throughout before trip out
Pump out from 18360'-14759'
Deepwater Horizon completes its drilling and the well is being prepared to be cemented so that another
rig will retrieve the oil. The blowout preventer is tested and found to be "functional." Gagliano now
reports that using only 6 centralizers "would likely produce channeling and a failure of the cement job."
4 flow checks during trip out-no flow
Make trip tp retreive wear sleeve
Retreval successful
Run 7"x9-7/8" production casing
Crossover at 12487
Float collar at 18114'
Shoe at 18304'
56' of rat hole
Laid out three joints of 7" due to damaged threads
Saw 10K weight bobble at 18218
9 attemps to convert float equipment
Gagliano's report says "well is considered to have a severe gas flow problem."
Schlumberger wireline cased hole crew arrives on Transocean Deepwater Horizon. Specifically, BP
contracted with Schlumberger to be available to perform a cement bond log and set a bridge plug and/or
cement retainer, should BP request those services.
Had to pressure up on the cement shoe valves nine times to convert from “filling the casing” to act as a
check valve, per BP morning report
Low pump pressures. Return flow after float shear out appeared to be high
Sheared at 3142 psi vs 500-700 psi design
Circulate 342 bbl before cement job
Pump nitrified foam cement
Estimated TOC at 17260'
Bumped plug with 1150 psi
Cement in place at 00:35
Bled back 5 bbls to 0 psi
Minimal calculated U-tube pressure after (nearly balanced)
Minimal U-tube may have prevented definitive float test
14 ppg mud in rathole with 16.7 ppg cement in shoe track
Halliburton completes cementing of the final production casing string.
BP officials gather on the platform to celebrate seven years without an injury on the rig.
Potential for contamination of cement in shoe track due to density difference between cement and mud
Release running tool
Set seal assembly at 5059' to seal the 9-7/8" casing annulus
Successful pressure test of seal assembly
Setting and testing procedure as per plan
Running string for the 9-7/8 X 7 inch casing pulled wet after the seal assembly test was completed.
Running string pulled three stands wet and so they slugged the wellbore with a 30 bbls - 16.3 ppg pill
Begin tripping out
Run in with tapered string for cement plug
6-5/8"x5-1/2"x3-1/2" drill pipe
Stop at 4700' (above BOP)
Close blind shear rams
At approximately 7:00 a.m., BP informs Schlumberger crew that no wireline cased hole services will be
requested and BP sends Schlumberger crew home.
At approximately 11 :15 a.m., Schlumberger crew departs Transocean Deepwater Horizon on regulorly
scheduled BP helicopter flight.
Positive test casing to 250 and 2500 psi
Finish RIH to 8367'
15 bbl gain in the trip tank after the casing test pressure was released, this seem a little large for pressure
bleed back for fluid compression and would expect 5 bbl gain.
Hard to track fluid volumes in the wellbore when you are pumping mud to boat (if from pits) and also
pump saltwater into the hole (from sea chest)
Mud transfer to boat begins at 13:28
Displaced booster line w/ seawater
Displaced choke line with seawater
Displaced kill line with seawater
1200 psi trapped in kill line
Pump 454 bbls LCM spacer (16.0 ppg)
Form-a-Set + Form-a-Squeeze combination
Viscous, solids-laden fluid
High u-tube pressure on DP of 2324 psi. Calculated u-tube should be 1628 psi.
Flow out exceeds flow in indicating the well is possibly flowing (per electronic data). Note the electronic
data shows increased gas units during this time period.
Kill line pressure holds at 1200 psi
Pump 352 bbls seawater
Not enough to get spacer above BOP
2325 psi static pressure after pumping
Calculated U-tube is 1628 psi
Shut annular
Bleed drill pipe pressure from 2325 psi to 1220 psi to equalize with kill line
High bleed back volume. Suspect the Annular Preventer is leaking at this point. Discovery Wells data
shows mud being transferred into the trip tank from the mud pits and 50 barrels of mud coming out of the
trip tank. Both Kaluza and Lambert statements confirm the rise was topped up at this time. Lambert
statement also indicates that the Annular was leaking. BP Trainee WSL (Lambert) on floor. First time
well temporarily underbalance when bled to 251 on the DP. First time well temporarily underbalance
when bled to 251 on the DP.
Pressure building drill pipe.
Open kill line
Pressure equalizes
Drillpipe pressure goes to 1400 psi
Kill line pressure drops to 645 psi
Bleed pressure to 273 psi on drillpipe as kill line pressure drops to zero
DP pressure never gets to zero
First time well is under balance
Observed that fluid level in the riser had dropped
Set up for negative pressure test began
Suspect the annular is leaking
Shut in drillpipe
Pressurer builds to 1250 psi in 6 minutes
Filled the riser with 50 bbls from trip tank
Mud offload to Bankston ends at 17:17
Performed first negative test down the workstring, had 1250 psi on the work sting. Some employees
recalled a disagreement between Transocean and BP on the rig floor about the negative test and pressure
on the work string.
60 barrels of spacer moved below annular
Increased annular activating pressure from 1200 to 1900 psi
Set up fluids through crew handover at 18:00
Under-displaced 16 ppg spacer
Spacer was not in MMS permit
Position under annular led to confusing pressure reading
Float equipment under tested by 285 psi
Mudloggers not informed that offloading had ceased
Bleed drillpipe from 1202 to 0 psi
An additional 15 bbls of fluid bled from DP.
IBOP is then closed
Pressure monitored through cement unit quickly rises to 790 psi and falls
Fluid bled from kill line and continues to flow. Opened kill line to Halliburton cement unit, had 700 psi
and bled 3 to 15 bbls. Flow did not stop and spurting could be indication of kill line plugging. Flow shut
in at cement unit at approximately 1759.
About fluid volumes due to movement below annular and line up for monitoring –either from drill pipe
(normal procedure used by rig) or kill line (MMS permit)
Either line up is appropriate and will correctly monitor well
Took about two hours for the company man to confirm a good second negative test due to 1400 psi on
the cement pump / displacement string.
Pressure slowly builds from 0 to 1400 psi over 31 minutes
Drillpipe pressure (monitored at Haliburton) stays steady at 1400 psi
Pumped on kill line to ensure full
Bled off 0.2 bbla to trip tank
Monitored kill line for 30 minutes
DP pressure builds to 1400 psi Kaluza and Vidrine arrive at rig floor together at approx.1910. Discussion
again about DP pressure anomaly. Apparently explained by TO personnel as 'bladder effect' or 'annular
compression'.
DP pressure stable at 1400 psi and no flow from kill line.
Prepare to displace with seawater
Pumped 1304 bbl seawater
Using rig pumps and booster
Shut down for sheen test - spacer back
1017 psi on DP when shut down
Sheen test passes
Mud circulation out prior to second plug –well reaches highest underbalanced pressure to this point.
Electronic data shows pit gain of approx. 40 bbls.
Flow out exceeds flow in indicating the well is possibly flowing (per electronic data).
Trip tank being discharged to pits through flow line (normal procedures ahead of change from oil to
water mud in active system) Start dumping of Trip Tank to flow line; Driller expects to see flow increase
(Gain 15.4 bbls)
At same point pumps ramp down for stop at static sheen test
Increased flow out due to discharge of trip tank
Driller expected to see flow increase
Flow returned near pre-tank discharge level when trip tank pump stopped, THEN increased
Potentially masked the gain
Flow out exceeds flow in indicating the well is possibly flowing (per electronic data).
Shut down for static sheen test to begin going over board with water-based spacer.
Pressure on drill pipe when shut down and flow from well. DP pressure increased from 1000 psi to 1250
psi during sheen test.
Sperry Sun sensors failure to record a flow out after 21:1021
Crew instructed to divert to divert returns overboard
Pumping stopped. Problem observed by rig floor and pumping is stopped. Possibly report from mud pit
room that mud returning and being sent overboard. Had pumped 265 bbls since sheen test.
Time taken to get well shut in.
Gas, oil and concrete from the Deepwater Horizon explode up the wellbore onto the deck and then
catches fire. One hundred twentysix people were on the Deepwater Horizon drilling rig when the incident
occurred. 11 remain unaccounted for; 17 were injured, 3 of them critically.

Risk Based Decision
Variable Bore Ram changed to Test Ram – acknowledged risk conversion will reduce built in redundancy

Centralizers – Halliburton proposed 21, BP went with 6.

Well Design –
a. Long string vs. tieback (provides additional barriers)
b. 7” from Nexen at last minute
c. Change of connectors
Circulate Bottoms Up – gas cut mud w/ cement (channeling)
Circulated bottoms up only to the wellhead rather than to the surface

Cement Bond Log – Schlumberger personnel on rig to run CBL and set bridge plug with equipment (4/18-4/20)
Schlumberger sent home due to interpretation of cement “analysis”
Not to run the OD lock ring and/or lock down sleeve – timing w/in procedure - BP elected to defer installation
of the lockdown sleeve until after the well had been displaced with seawater
Pumping mud to boat while displacing riser – unable to accurately monitor volume in-out
LCM Spacer – pumped 450 bbl LCM as spacer across BOP/choke-kill lines
Negative test interpretation and proceeding forward – lack of define procedure and successful test

Timing of setting the surface plug
Cement designed for balanced not overbalanced
Deviating from own recommended practices – API RP 65
Continuing operations w/BOP leaks and yellow pod functions being locked out
Cut back on cement to have enough room to run CBL
Decision to forgo drilling survey /ABS since 2005
Utilization of nitrogen foamed cement at this depth - use of Foam Cement a Poor Choice?
- May be uncommon at this depth
- Typically used for shallow conductor casing string
Did the operator give the cement enough time to cure? (from Halliburton lab test reports)
- Test on 3/29 of 9-7/8”liner slurry (previous casing): 15 hours needed to reach 2100 psi compressive strength
- Test on 4/12 of 7”casing slurry : 0 psi compressive strength after 24 hours; needed 48 hours to reach
compressive strength of 1590 psi
o Negative test started ~18 hours after pumped

Was the volume for 7”production casing cement job appropriate?
- 60 bblspumped (requested third party caliper logs to determine if adequate)
- 16.7 ppgcement in shoe track over 14 ppgmud in open hole beneath the 7”shoe
o could fall out into the open hole
- Estimate of 2 bblsnitrogen cement in shoe track –normally would pump all into annulus

Wiper plug was run through two casing internal diameters

1st positive test on casing against wiper plug at 10 hours set time

Was outer lock ring run on assembly?
- Need to understand rating or tolerance for pressure on annulus side

Running production casing that was pre-doped shoreside & probably no inspection on rig floor.
Positive pressure tests on cement and casing too low.
Circulated out riser with no pit level monitoring at any point.
Ignored pvt indications of excess flow while circulating out riser first hour and 10 minutes-to 21:10 hours 4-20-
10.
Bypassed pvt flow-out indicator after 21:10 by putting returns directly overboard.

Ignored drill pipe pressure with pump off at 21:20 and 21:30 with seawater most all the way around.
Not watching for riser flow with pump off at those times or not responding to an apparent flow
Not closing bop and diverter at 21:20 to monitor pressures and divert flow overboard.
Outcome
Failure to Activate BOP

Due to model
i. <10 suggested
“moderate gas possible”
ii. 6 suggested “SEVERE”

Insufficient barriers

Potential cuttings in well
