RXSOL ORG – 15 (Asphasol)

Description

RXSOL ORG -15 (Asphasol)  shale inhibitor is a partially water soluble, water dispersible blend, containing sulfonated organic resins for water-base muds. It aids in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Being partially soluble, RXSOL ORG -15 (Asphasol) has the capability of plugging micro-fractured shales and sealing shales so that the hydrostatic overbalance from the fluid column is not transmitted to the pore pressure network of shale formations adjacent to the wellbore.

Application:

RXSOL ORG -15 (Asphasol)  can be used in most water base muds. It is a free-flowing powder and can be added directly to the mud system through the mixing hopper. Unlike other shale control additives, it is not necessary to premix Rxsol ORG -15 (Asphasol)  with oil and it contains no surfactants. Normal concentrations of Rxsol ORG -15 (Asphasol)  range from 4 to 10 lb/bbl (11.4 to 28.5 kg/m3) for most applications.

In water‐base drilling fluid systems, Rxsol ORG -15 (Asphasol)  inhibitor exhibits the following characteristics:

•     Stabilizes shales.
•     Lowers torque and drag.
•     Reduces high‐temperature fluid loss.
•     Produces thin‐walled filtercakes.
•     Improves bore hole stability.
