OBM CHEMISTREY & SOLIDS ANALYSIS – GEL MUD CHEMISTREY
OUTPUT
MISCELLANEOUS CALCULATIONS
1- INCREASING MUD WEIGHT BY USING BARITE
2- EXCESS VOLUME DUE TO ADDING BARITE
3- INCREASING MUD WEIGHT DUE TO ADDING CaCo3
4- EXECSS VOLUME DUE TO ADDING CaCo3
5- REQUIRED BENTONITE FOR GEL MUD
6- EXECSS VOLUME DUE TO ADDING BENTONITE
7- FINAL MUD WEIGHT DUE TO MIXING TWO DIFFERENT MUD WEIGHTS
8- DECREASING MUD WEIGHT BY USING WATER
9- DECREASING MUD WEIGHT BY USING OIL
10- SOME CONVERSIONS
11- EFFECT OF TEMP. ON DENSITIES OF CaCl2 AND NaCl SOLUTIONS
OIL-BASED MUD CALCULATIONS
1- Ca Cl2 CONTENT IN OIL-BASED MUD
2- OIL/WATER RATIO
3- BRINE CONVERSIONS
4- BRINE ACTIVITY (Aw) CURVE FIT EQUATIONS
5- INCREASING BRINE SALINITY
6- DECREASING BRINE SALINITY
7- INCREASING OIL/WATER RATIO
8- DECREASING OIL/WATER RATIO USING WATER
9- DECREASING OIL/WATER RATIO USING BRINE
10- SOLID CALCULATIONS
11- BRINE SALINITY
A-SINGLE-SALT SYSTEM
CaCl2
NaCl
B-TWO-SALT (BINARY) SYSTEM
TO CALCULATE THE EXACT AMOUNTS OF EACH SALT PRESENT IN AN EMULSION SYSTEM
CONTAINING BOTH CAL. AND SOD. CHLORIDE, THE CA.++ CONTENT MUST BE TITRATED
IN CASE USING LIME , THE SOURCE OF CA++ WILL BE DUE TO LIME AND CaCl2
HYDRAULICS AND SURGE-SWAB CALCULATIONS & BIT OPTIMIZATION
1- ANNULAR VELOCITY
2- OIL/WATER RATIO
3- BRINE CONVERSIONS
4- BRINE ACTIVITY (Aw) CURVE FIT EQUATIONS
5- INCREASING BRINE SALINITY
6- DECREASING BRINE SALINITY
7- INCREASING OIL/WATER RATIO
8- DECREASING OIL/WATER RATIO USING WATER
9- DECREASING OIL/WATER RATIO USING BRINE
