Oil‑Base Drilling Fluid Organoclay (CAS 68953‑58‑2) is drilling‑grade organophilic bentonite modified by organic quaternary ammonium salt, designed as viscosifier and rheology control additive for diesel‑based and mineral‑oil‑base drilling mud. Under high‑speed shearing together with suitable polar activator, clay platelets exfoliate and build reversible thixotropic gel network inside continuous oil phase. At static or low‑shear condition, the network suspends rock cuttings and heavy weighting m

Product Detail

Product Overview

Oil‑Base Drilling Fluid Organoclay, CAS 68953‑58‑2, is produced from high‑purity natural montmorillonite through organic cation surface modification. This drilling‑special organophilic bentonite serves as primary viscosifier and gelling agent for diesel‑oil and mineral‑oil‑based non‑aqueous drilling fluids. Unlike coating‑grade organoclay, this drilling grade requires appropriate polar activator combined with vigorous high‑speed shearing in oil‑base mud mixing tanks to realize complete exfoliation of silicate platelets. Exfoliated silicate sheets form a reversible three‑dimensional colloidal thixotropic network in the continuous oil phase of drilling mud. When mud circulation is paused, the established gel network suspends rock cuttings, barite and other weighting agents effectively, avoiding heavy solid settlement at the bottom of mud tanks. During pumping and down‑hole circulation, strong mechanical shear breaks the colloidal network, lowering fluid viscosity to decrease pump load and improve mud flow property. Once pumping stops, gel strength recovers quickly to lock solid particles in suspension. The product retains stable rheological characteristics at elevated down‑hole temperature, helps control filtration loss toward porous formations and suppresses hydration‑swelling of water‑sensitive shale strata. It maintains consistent batch‑to‑batch quality for on‑site oil‑base mud preparation in onshore and offshore oil‑gas drilling projects.

Key Features

‑ Drilling‑special organophilic bentonite, dedicated viscosifier for diesel and mineral‑oil‑base drilling fluid systems ‑ Needs matched polar activator and intensive high‑speed shearing to achieve full exfoliation of silicate platelets ‑ Builds controllable gel strength for suspension of rock cuttings and high‑density weighting agents such as barite ‑ Typical shear‑thinning rheology: reduces pumping resistance during circulation while providing static suspension capacity ‑ Good high‑temperature rheological stability under down‑hole thermal conditions ‑ Assists in reducing fluid loss and restrains hydration swelling of water‑sensitive shale formations ‑ Free‑flowing fine powder, convenient for continuous feeding during on‑site mud mixing operations ‑ Reliable batch‑to‑batch consistency for land‑based and offshore oil‑gas drilling fluid preparation

Technical Specifications

‑ Product Name: Oil‑Base Drilling Fluid Organoclay ‑ CAS Number: 68953‑58‑2 ‑ Appearance: Light off‑white fine powder ‑ Moisture: ≤3.5 % ‑ Loss on ignition: 33.0‑42.0 % ‑ Fineness (325 mesh residue): ≤2.5 % ‑ Bulk density: 0.22‑0.33 g/cm³

Application Scenarios

‑ Diesel‑oil‑base invert emulsion drilling mud for on‑shore oil‑gas well drilling ‑ Mineral‑oil‑base non‑aqueous mud for directional wells and horizontal wells ‑ High‑temperature deep‑well oil‑base drilling fluid formulations ‑ Off‑shore drilling non‑aqueous mud systems requiring cuttings suspension control ‑ Viscosifying and gelling additive for oil‑base drilling fluid service companies

Usage Recommendation

‑ Typical dosage range: 2.0‑6.5 wt% based on total oil‑base mud formula ‑ Slowly add organoclay powder into base oil under vigorous high‑speed agitation, then introduce polar activator to promote platelet exfoliation during mud compounding ‑ Sufficient high‑speed shearing is critical for target viscosity and gel strength; inadequate mixing will result in poor thickening and sedimentation risk of weighting solids ‑ Perform laboratory mud evaluation including rheology, gel strength, high‑temperature aging test and fluid‑loss measurement prior to on‑site formulation ‑ Adjust addition dosage according to target mud viscosity, well depth and anticipated down‑hole temperature; excessive loading may lead to overly high plastic viscosity and poor pump‑ability

Package & Storage

‑ Standard packing: 25kg kraft paper bag with inner PE liner ‑ Store in cool, dry and ventilated warehouse; protect powder against moisture and heavy compression ‑ Keep bags tightly sealed after opening to prevent moisture ingress ‑ Shelf life: 12 months under proper storage conditions

Safety Notes

‑ Avoid dust generation and inhalation during material handling; wear suitable dust mask and safety goggles. ‑ Prevent direct skin contact; chemical‑resistant gloves are required for operation. ‑ Keep away from open flame and high‑temperature heat sources. ‑ Please refer to SDS document for comprehensive guidance on handling, transportation and emergency disposal.
