4 The Darcy Difference COMPLETION STRENGTH AND CONTROL Positive Wellbore support preventing mobilisation of problematic sands, shales, coals etc. Mechanical strength and collapse resistance for high geo-mechanical loads and extreme conditions Conform to the borehole whilst maintaining base pipe geometry Premium sand control combined with ICD capability and zonal isolation Selective production, injection and shutoff with maximum ID Independent ISO Collapse Testing achieving 6,000psi and Mechanical Crush Testing beyond API base pipe ratings OPERATIONAL EFFICIENCY Minimise exposure to operational complexity, risk and cost Eliminate specialist pumping crews or additional downhole tools Easy integration with standard completion equipment Realise logistical savings on transportation, boats, helicopter, deck and bed space Environmentally neutral, no pumping equipment or fluid disposal Integration to standard completion equipment and rig practices Run in Activation Wellbore Support Control, Selectivity and Shut off Copyright Darcy 2015, CONFIDENTIAL 4

5 Explore New Possibilities Application Types Our environmentally neutral system lends itself to even the most remote or sensitive locations Mature & low pressure reservoirs Endurance hydraulic screen is the ideal solution when, in a low bottom hole pressure environment, circulating a gravel pack is not an option. HPHT Stimulate the filter cake ahead of activation and benefit from completion strength that is not subject to mechanical failure when the reservoir is depleted over time. Injector wells Maintain borehole support and near wellbore stability throughout injection and shut-in. Protect injection performance by effective placement of filter cake treatment before screen activation. Zonal selectivity and ease of well intervention for added assurance. Horizontal & Multi-lateral wells Complete more complex wells with greater ease and less risk, when gravel packing isn t an option. Deep water and Shallow Reservoirs Eliminate the time and complexity of gravel packing, removing pumping operations in wells with small pore pressure / fracture gradient window. Heavy Oil applications Benefit from completion strength, preventing the loss of sand integrity when greater drawdown loadings occur when extracting hydrocarbons with high viscosities, especially under ESP conditions.
