Transocean engineers wanted to keep the pressure in the borehole under control with heavy mud while Halliburton set the cement plugs.

Sometimes, though, it comes down to the sort of game where hard grunt is the key - half the season is played in rain and heavy mud and Bath maybe just lack a little bit of dog.
On Friday, one day after announcing it had pinpointed the source of the leak, Total detailed its dueling approaches to stop it: blocking the outflow with "heavy mud" (consisting of a mixture that contains mineral compounds) and drilling a pair of relief wells.
Given the two red flags that had been thrown up previously, one would have expected that as a precaution a cement plug would have been placed somewhere in the wellbore as a secondary pressure seal before this primary pressure control system (heavy mud) was evacuated from the wellbore.
This is what this data is supposed to monitor, but the well flow evidence would appear to have been ignored, because at this point the BP rig supervisors should have gone to a well kill operation and started to pump heavy mud back into the well bore to restore the primary control mechanism.
And following the intersection of the well bore with those relief wells, they will put heavy mud down there to suppress the pressure of the oil coming up from the reservoir, put a cement plug in and effectively do what I would call a bottom kill, as opposed to the top kill, which was not successful a couple of weeks ago.
The solutions for -- the solution with the top kill, first in stabilizing the well with heavy drilling mud, ultimately would lead to the cement capping of that well.
Above it the Q4000 rig and three attendant vessels have 50, 000 barrels of peculiarly heavy drilling mud and pumps capable of providing 30, 000 horsepower with which to muscle that mud into the well.
On May 26th BP, the company responsible for the well that Deepwater Horizon had drilled, started to pump heavy drilling mud into the well's blowout preventer, a set of valves on the sea floor.

Davy Jones was so eager to cough up its bounty from a massive high-quality reservoir 200 feet thick that McMoran several months ago had to control the flow by filling the hole heavy drilling mud.
When the heavy drilling mud that provides the pressure needed to keep things from coming up the well was removed, first as a test, then as part of a procedure for closing down the well and moving the rig, telltale signs that something was wrong were missed.
The French had spent many years and thousands of lives trying to build a canal to connect the Atlantic and Pacific oceans and had been defeated by year-round heavy rains in mountainous mud, deadly diseases, and impossible expenses.

Last year's event was marred by heavy rain, which turned many car parks into mud baths with some festival-goers forced to sleep in their cars as traffic became gridlocked.
Halliburton said that the report "accurately places responsibility on BP as the well owner for its operational decisions, " which included using a heavy fluid designed to keep gas from entering the well, called drilling mud, that was "too light" and probably mixed with the cement at the bottom of the well, and drilling too narrow a well.
This year, heavy rain turned the festival site at Seaclose Park, Newport, into a mud bath, which forced festival-goers to sleep in their cars as traffic became gridlocked.
The explosions were accompanied by heavy rain, leaving the island's roads coated in a thick layer of mud.
Thursday's heavy rain led to the cancellation of two mountain stages, before the fourth was scrapped because of mud on the road and stage five was shortened for the same reason.
