Drilling & Completion Chemistry

Objective: To establish and secure a hydraulically and mechanically competent wellbore that provides zonal isolation and preserves reservoir deliverability.
This phase employs formulated fluid systems to achieve core operational goals: the drilling fluid maintains wellbore stability, controls subsurface pressures, transports cuttings, and minimizes formation damage, while the cement slurry provides structural casing support and permanent hydraulic isolation between geological zones. The principal engineering challenges involve managing fluid loss and rheology under high-pressure/high-temperature (HP/HT) conditions, mitigating reactive shale interactions, preventing gas migration during cement curing, and ensuring compatibility between all fluids and the reservoir to safeguard initial productivity. Success is measured by achieving a gauge hole, competent cement bond logs, and minimal skin damage.

BRITOLY SI 9020

High-Calcium Completion Fluid Protector

Description:
BRITOLY SI 9020 is a specialised, high-strength scale inhibitor engineered for completion brines with extreme calcium content. This robust chemistry prevents both sulphate and carbonate scaling during the critical well suspension and initial flow back phases, ensuring formation integrity is preserved from the moment production begins.

• Application Summary:

  • Primary Use: Protection of completion fluids and near-wellbore area in high-TDS, high-calcium environments.

  • Ideal For: Wells requiring dense completion brines where scaling could damage screens, gravel packs, or formation permeability.

  • Key Benefit: Superior calcium tolerance that prevents inhibitor precipitation and formation damage in the most challenging brine conditions.

BRITOLY SI-400

HP/HT Completion & Squeeze Inhibitor

Description:
BRITOLY SI-400 is a premium, high-concentration cyclic phosphonate designed for thermal resilience. Engineered for stability above 120°C (250°F), it delivers reliable scale inhibition where conventional chemistries fail, protecting wellbore equipment during completion and providing long-term reservoir defence.

• Application Summary:

  • Primary Use: High-temperature downhole squeeze treatments and HPHT well completions.

  • Ideal For: Protecting screens, liners, and the formation in thermally challenging reservoirs during and after completion operations.

  • Key Benefit: Exceptional thermal and hydrolytic stability ensures performance integrity in the most severe downhole environments
