INSTRUCTIONS N.B. Periodically check the calibration of the Marsh funnel by measuring the viscosity of fresh water. The Marsh funnel viscosity of one quart of fresh water at 21 ± 3 C is 26 ± 0.5 seconds. If the funnel is out of calibration, clean it using a pipe cleaner to make sure that nothing is obstructing the outlet. If the funnel continues to give an incorrect reading for fresh water after cleaning, then the outlet tube has probably been damaged, and the funnel should be replaced. INSTRUMENT CARE Follow these suggestions to care for the Marsh Funnel: Clean and dry the funnel thoroughly after each use. Take special care not to bend or flatten the brass outlet tube at the bottom of the funnel. The Marsh Funnel Viscosity readings are computed using the exact diameter of this outlet and if the outlet is distorted the readings will be inaccurate. Mudlogic Fluid Solutions can provide customised fluid solutions to suit particular geological conditions. MUDLOGIC: P.100

INSTRUCTIONS MUD BALANCE INSTRUCTIONS The density or weight of a given volume of liquid is determined by using a mud balance. The arm is graduated and permits accurate measurements to within ±0.1 pounds per gallon or ±0.01 specific gravity. The balance is constructed so that the fixed volume cup at one end of the beam is balanced by a fixed counterweight at the opposite end, with a sliding weight rider free to move along the graduated scale. A level bubble mounted on the beam indicates when the system is in balance. Specifications: 6.5 - 23.0 lbs/gal 0.79 - 2.72 specific gravity 49 - 172 lbs/ft3 340 - 1190 psi/1000 ft EQUIPMENT Mud Balance Lid Fulcrum or Knife Edge PROCEDURE 1. Place the mud balance base (preferably in carrying case) on a flat level surface. 2. Measure the temperature of the fluid and record on the appropriate mud report form. 3. Fill the clean, dry cup to the top with the freshly obtained mud sample to be weighed. 4. Place the lid on the cup and set it with a gentle twisting motion. Be sure that some mud is expelled through the hole in the cap as this will ensure the cup is full and also will free any trapped air or gas. 5. Cover the hole in the lid with a finger and wash all mud from the outside of the cup and arm. Then thoroughly dry the entire balance. 6. Place the balance on the knife edge and move the rider along the outside of the arm until the cup and arm are balanced as indicated by the bubble. 7. Read mud weight at the edge of the rider toward the mud cup. MUDLOGIC: P.101

INSTRUCTIONS 8. Clean and dry the mud balance after each use. Results: Report the mud weight to the nearest 0.1 pound per gallon, 1.0 pound per cubic foot, 0.01 gram per cubic centimetre (specific gravity) or 10 PSI/1000 ft. CALIBRATION OFITE mud balances are calibrated at the factory with the lid included in the mud balance kit. However, the balance should be re-calibrated, if necessary, on site. Any time a mud balance lid, or any other part, is replaced, the instrument should be re- calibrated. 1. The calibration of the instrument may be easily checked by measuring the density of fresh water. 2. Fill the cup with fresh water at around 21°C and set the rider on 8.3 pounds per gallon or 1.0 specific gravity. Add or remove steel shot from the shotwell until the instrument is in balance. CARE OF EQUIPMENT After each use of the Mud Balance, wash the unit thoroughly to ensure no dirt or drilling fluid remains stuck to metal surfaces. Build-up of dried fluid or dirt will affect future balance readings. Mudlogic Fluid Solutions can provide onsite technical support 24/7 with no job too big or too small! MUDLOGIC: P.102

INSTRUCTIONS HALF AREA FILTER PRESS INSTRUCTIONS The mechanism of controlling water phase invasion into surrounding strata is through filtration control which is the creation of an impermheable barrier or filter cake composed of specialised polymers, select products and drilled cuttings. The Half Area Filter Press consists of a modified low-pressure regulator with a CO2 bulb pressurizing assembly and a filtration cell body. A rubber diaphragm boot contains the fluid and separates it from the pressurizing gas. This enables the unit to be operated while inverted, which negates the effect of particles settling on the filter medium prior to pressurization. EQUIPMENT Half Area Filter Press 10 ml graduated cylinder Timer PROCEDURE 1. Unscrew the cell cap from the cell body. 2. Seat the rubber boot inside the cell to ensure a tight seal. 3. Fill the rubber boot with test fluid. Do not fill to closer than 5mm from the top of the boot. Be careful not to spill any fluid on the edge of the boot. Exercise care when handling the cell when it is filled with fluid so that the valve is not accidentally opened before the cell cap is screwed into place. 4. Place a sheet of filter paper across the top of the boot. 5. Hand tighten the cell cap firmly. 6. Mount the cell assembly on a wall or kit bracket and place a 10-mL graduated cylinder under the filtrate tube to catch the filtrate. 7. Push the Relief Valve forward toward the front of the unit. Place a CO2 (sold separately) cartridge into the cartridge barrel and screw it onto the filter press body until the cartridge punctures. 8. Pressurize the cell by pushing the relief valve toward the back of the cell and rapidly screwing the regulator T-screw into the regulator so that 100 ± 5 PSI (690 ± 35 kPa) is applied in 30 seconds or less to the cell body. The test time period begins when pressure is applied. MUDLOGIC: P.103

INSTRUCTIONS 9. Record the volume of filtrate collected to the nearest 0.1 cm3 as the API filtrate. Correct the filtrate volume collected to a filter area of 7.1 in² by multiplying the volume by 2. Also record the temperature of the fluid, the time of the test, and the pressure used. 10. When the test is complete, release the pressure inside the test cell by unscrewing the T-screw on the regulator. When the pressure gauge reads 0 PSI, push the relief valve forward. 11. You can now remove the end cap. Save the filtrate for chemical testing. 12. Be very careful to save the filter paper without disturbing the cake. Gently wash the filter cake on the paper and measure the thickness to the nearest mm. Report cake characteristics as hard, spongy, firm, etc. 13. To perform additional tests, simply refill the rubber boot with new test fluid and tighten the cap in place. 14. Then, push the relief valve toward the back of the unit to pressurize the cell and initiate the test. 15. When you are finished testing, unscrew the cartridge barrel and discard the spent cartridge. CARE OF EQUIPMENT If the pressure gauge registers insufficient pressure after the T- screw has been screwed into the regulator, the CO2 bulb is probably exhausted. Push the relief valve toward the front of the cell and return the T-screw to its maximum outward position. Remove the barrel from the pressure unit and discard the spent bulb. Place a new CO2 bulb into the barrel and screw the barrel back into the puncture assembly. Do not over tighten, as this will result in a loss of CO2 gas. Thoroughly clean and dry the filter press unit immediately after each use. Protect CO2 bulbs from sunlight and other sources of heat. Lubricate the bleeder valve O-rings with a film of silicone grease for extended life. MUDLOGIC: P.104

INSTRUCTIONS SAND CONTENT INSTRUCTIONS One of the primary functions of a drilling fluid is to carry drilled solids from the well bore. These solids are a contaminant, and if left in the system, can lead to numerous problems. The Sand Content Kit determines the volume percent of sand-sized particles in the drilling fluid. API defines sand-sized particles as any material larger than 74 µm (200 mesh) in size. The test can be performed on low solids fluids as well as on weighted fluids. The kit consists of a glass tube graduated to read percent (%) by volume, a funnel, and a 200-mesh sieve contained in a cylindrical shaped holder. EQUIPMENT Wash bottle Sieve, 200 mesh (75 µm) 2.5” Diameter Funnel, plastic Graduated Tube, Glass 0-20 PROCEDURE 1. Fill the sand content tube to the indicated mark with mud. Use the wash bottle to add water (or diesel oil for oil-based drilling fluids) to the next mark. Close the mouth of the tube and shake vigorously. 2. Pour the mixture onto the clean screen. Discard the liquid passing through the screen. Add more fluid from the wash bottle to the tube, shake, and again pour onto the screen. Repeat until all the drilling fluid has been washed out of the tube. 3. Flush the screen with fluid from the wash bottle to free the sand remaining on the screen of any remaining mud. 4. Fit the funnel upside down over the top of the screen. Slowly invert the assembly and insert the tip of the funnel into the mouth of the glass measuring tube. Wash the sand into the tube by spraying a fine spray of fluid from the water bottle through the screen (tapping on the side of the screen with a spatula handle may facilitate the process). Allow the sand to settle. 5. Using the scale on the graduated tube, read the volume percent of sand. Report this along with the source of the mud sample (above shaker, suction, pit, etc.). MUDLOGIC: P.105

INSTRUCTIONS Coarse solids other than sand (lost circulation material, coarse barite, coarse lignite, etc.) may be retained on the screen. The presence of such solids should also be noted. CARE OF EQUIPMENT 1. Thoroughly wash any sand or drilling fluid from the screen, funnel, and tube after each use. Dry all equipment. 2. Refill the wash bottle. Mudlogic Fluid Solutions can provide a comprehensive range of analytical and laboratory support services upon request. MUDLOGIC: P.106
