By | | ,
Leave a comment

The second part of unit conversion is the conversion for  Length,Mud Weight and Power specially used in the oil field.

The RED number is the conversion unit.

Length

Feet x 0.305 = Meters

Inches x 25.4 = Millimeters

Inches x 2.54 = Centimeters

Centimeters x 0.394 = Inches

Millimeters x 0.03937 = Inches

Meters x 3.281 = Feet

Mud Weight

Pounds/gallon x 7.48 = Pounds/cu ft

Pounds/gallon x 0.12 = Specific gravity

Pounds/gallon x 0.1198 = Grams/cu cm

Grams/cu cm x 8.347 = Pounds/gallon

Pounds/cu ft x 0.134 = Pounds/gallon

Specific gravity x 8.34 = Pounds/gallon

Power

Horsepower x 1.014 = Horsepower (metric)

Horsepower x 0.746 = Kilowatts

Horsepower x 550 = Foot-pounds/sec

Horsepower (metric) x 0.986 = Horsepower

Horsepower (metric) x 542.5 = Foot-pounds/sec

Kilowatts x 1.341 = Horsepower

Foot pounds/sec x 0.00181 = Horsepower

Oil Field Conversion Part 1 – Area, Circulation Rate, Impact Force

Working in the oil filed, you may need to convert some unit values to another unit valves.  I have some conversion unit specially used in the drilling and working over industry.  I have 3 parts of the oil field conversion unit. This is the first part which is the conversion of Area, Circulation Rate, Impact Force.

The RED number is the conversion unit.

Area

Square inches x 6.45 = Square centimeters

Square inches x 645 = Square millimeters

Square centimeters x 0.155 = Square inches

Square millimeters x 0.00155 = Square inches

Circulation Rate

Barrels/min x 42 = Gallons/min

Cubic feet/min x 0.000472 = Cubic meters/sec

Cubic feet/min x 7.48 = Gallons/min

Cubic feel/mm x 28.32 = Liters/min

Cubic meters/sec x 15850 = Gallons/min

Cubic meters/sec x 2118 = Cubic feet/min

Cubic meters/sec x 60000 = Litres/min

Gallons/min x 0.0238 = Barrels/ruin

Gallons/min x 0.134 = Cubic feet/min

Gallons/min x 3.79 = Litres/min

Gallons/min x 0.00006309 = Cubic meters/sec

Litres/min x 0.00001667 = Cubic meters/sec

Litres/min x 0.0353 = Cubic feet/min

Litres/min x 0.264 = Gallons/min

Impact Force

Pounds x 0.0000445 = Dynes

Pounds x 0.454 = Kilograms

Pounds x 4.448 = Newtons

Dynes x0.00000225 = Pounds

Kilograms x 2.2 = Pounds

Newtons x 0.2248 = Pounds

I hope this conversion unit will be advantageous for you.

Latest information about West Atlas and please find the media release from PTTEP t from the link below. You will see the photos of West Atlas after well control situation burnt the rig and the platform in Timor sea.

http://www.coogeeresources.com.au/uploads/MediaRelease96_23-11-09.pdf

From “Upstream Online” 23/11/09.

Crew Boards Crippled Montara Platform

A three-man team has boarded the Montara wellhead platform for the first time since a blowout at the Timor Sea installation on 21 August.

The crew, from Alert Well Control, are evaluating the damage to the Seadrill-owned jack-up West Atlas and the platform, PTTEP said.

The evaluation will also include a safety assessment as PTTEP considers how best to plug and fully secure the Montara H1 well.

PTTEP said the wellhead platform and blown-out H1 well remain stable after the leaking bore was successfully killed on 3 November.

Company director Jose Martins said a preliminary assessment of the rig shows extensive damage to equipment from a fire which erupted on the wellhead platform on 1 November.

He said the reboarding team were surveying the structural integrity of the West Atlas’ cantilever which buckled in the platform fire.

“PTTEP will ensure everything possible has been done to assess the risks before undertaking the plugging operation. The safety of personnel remains our first priority,” Martins added.

clay stone and shale=Clay Stone & Shale (Clst&Sh).

Clay Stone & Shale are formed from accumulation of clay minerals and silt particles. Its grain size is less than 4 microns.

 

 

marl= Marl (Mrl).

Marl is formed from accumulation of clay minerals and calcium carbonate (calcite) and its grain size is less than 4 microns.

 

sand stone= Sandstone (Sst)

Sandstone is formed of accumulation of mineral grains (quartz) and its grain size is from 60 microns to 2 mm.

 

silt stone= Siltstone (SLst)

Siltstone is formed of accumulation of mineral grains (quartz) and its grain size is from 4 to 60 microns.

 

conglomolate= Conglomerate (Cgl), its grain size is greater than 2 mm.

Conglomerate is formed from accumulation of primarily granule, pebble and boulder size particle.

 

fault= Geological fault

It is very important to understand what geological description used in oil filed business. Hence, I collect the geological description from the book in order to be your reference and you will be able to understand meaning of each photo describing type of rock.

lime stone = Limestone (Ls)

dolomite and shalk = Dolomite&Chalk (Dol & Chk)

chert = Chert (Cht)

Limestones, Dolomite and Chalk are formed from large deposit of calcium carbonate (calcite) and calcium magnesium (dolomite).

gypsum = Gypsum & Anhydrite (Gyp & Anhy)

salt = Salt (Sa)

Gypsum, Anhydrite and Salt are composed of minerals precipitated from solution during evaporation of water.

basement = Basement (Bm)

volcanic = Volcanics (Volc)

Basement and Volcanics are formed from the cooling of molten magma.
