So where are you tonight?

Sorry - I\'ve always had good time in Denmark ....

OK - I have clients there and that sort of influences things when they take me out !!

Tonight ..... listening to my old cassettes (yes ... musicassettes ......... you know those things before CD's ) .... and enjoying Home Brew tasting ...... SWMBO already not "too pleased" ....................
 
Quinta do Lorde, Madeira.

Just heard an old friend is coming out on Monday to join us for the leg to the Canaries. Quiet day, finally started putting the cones on the series drogue.

Thankfully tied up in Bergen, it was 'orrible out there, and the plonkers who thought we could work in it soon realised their dich swinging was getting us nowhere.

life in a blue suit huh I got off a day early last week /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif but my plane got fogged off /forums/images/graemlins/grin.gif nothing easy is it /forums/images/graemlins/shocked.gif

are there many due off then ? mebbe they will shoot you in for crew change /forums/images/graemlins/cool.gif
 
can't believe they have kept us out here for this. They get the same local forecast as we do. We finished the first zone on Thursday and got another to do.
It's costing them a fortune to keep us floating around out here.
We are 3 to go off and 5 to come on this week.
 
All good things must come to an end... our bunch've decided to coast us up to a more sheltered worksite. Only a fully loaded passage to get there. Ugh. And to think I should've been getting off myself this week but asked to extend!

DP- a blessing and a curse.
 
basically, once a well has been drilled, it either flows as required or not. If not then there are certain things which can be done. Oil and gas are generally produced from either sandstone or limestone formations. What we do is one of 2 things.

A Primer of Oilwell Stimulation - by me

1. in sandstone formations, we can pump large volumes of Hydrochloric acid generally reduced in strength to something like 15%, by us and pumped down into the well at high rates and pressures, also by us. This has the efect of dissolving all the crud binding the sand up and filling all the spaces between the grains. Once dissolved and flowed back, then the oil/gas can flow between the grains to the surface.

2. in limestone it is very different as the rock structure is very tight and the oil/gas cannot flow through it. In this case, we pump under very high pressure(up to 10,000psi and higher), and at high rates(1500ish gallons per minute). We pump a heavy Gel like system which can carry various weights of 'sand'(up to around 13 lbs per gallon). These high pressures initiate cracks(fractures in the limestone), and the sand we inject into these holds the formations open, once the pressure is off. The gel then breaks down and flows back to surface followed by the oil/gas through the sand filled crack.

Simple really.

We can currently carry 180,000 gallons of Hydrochloric acid at up to 36%. As strong as it comes.
We can also carry over 2 million ponds of 'Sand'
Plus all the chemicals we need to produce the required highly engineered fluids.

Here endeth the lesson, hope it helps. /forums/images/graemlins/smile.gif
