Mud Sample Analysis
Mud Samples
- Density and specific weight (hydrometer & pressurized mud balance)
- Water loss time using (Ring-apparatus)
- Amount of filtrate, filter cake thickness, filter cake texture (BAROID filter press: room temperature (T=RT; pmax=0.7 MPa) & HPHT (Tmax=200 °C; pmax=4.2 MPa))
- Salt and lime content of the filtrate (burette titration method)
- Drainage time, remaining drainage time
(marsh funnel) - Solid content (sieving and drying)
- Sand content (sieve with 0.05 mm mesh size and evaporation method)
- pH value (pH meter)
- Flow behavior (apparent and plastic viscosity), gel strength (Fann-VG-Viscometer), HPHT Viscometer
- Thermal stress (BAROID roller oven, Tmax=220 °C; pmax=7 MPa)
- Blending (IKA agitator & Hamilton Beach mixer)
Investigation of Dry Residual Sand
- Lime content, clay content
- Natrium and potassium content
Frac Fluid Investigation
- Fluid characteristics (density, specific weight, pH value, flow behavior, gel strength)
- Amount of filtrate (filter press, room temperature, p=0.7 MPa, HPHT (Tmax=200 °C; pmax=4.2 MPa))
