ORCA for OBM – Control your cleanup


Uniformly remove oil-based mud filter cake damage in long horizontal sections and deviated wells to optimize productivity.

ORCA for OBM treatments provide the industry with an engineered, highly effective, dual attack on oil-based mud filter cakes in a single treatment. Single step hydrocarbon solubilization with speciality surfactants combined with unique in-situ acid generation to dissolve carbonate achieves a uniform treatment along the whole wellbore to optimize zonal coverage, regain and improve permeability, minimize the risk of water or gas coning and avoid the creation of thief zones. The fluid’s benign chemistry is low hazard for users and the environment and therefore compatible with complex and expensive completion hardware and ‘jewellery’. Generally, complex completions are incompatible with many harsher chemical treatments so a gentler but effective alternative is required.

ORCA for OBM ensures uniform wellbore cleanup, the cleanest wells and maximizes well production to deliver significant financial benefits. ORCA for OBM remedial treatments of a series of wells in Asia drilled with an OBM and completed with standalone sand screens delivered increases in production of up to 1,400 bopd or 500%.
