Paper presented at the SPE Asia Pacific Hydraulic Fracturing Conference, August 24–26, 2016
Paper Number: SPE-181786-MS
.... Interactions between the polymer and divalent cations in seawater inhibit proper polymer hydration, thus preventing generation of an elastic polymer network and potentially affecting the crosslinking mechanism. In this study, concentrations of critical ions in seawater were reduced using a reliable seawater...

... proppant (RCP) was used at a maximum concentration of 720 kg/m 3 in the tail stage. A total of 851 tonnes of proppant was pumped in 3156-m 3 crosslinked fluid. The seawater-based fluid properties present an innovative approach to address the water requirement issue for offshore stimulation operations...

..., at significantly lower concentrations in lab bottle tests. Borate fluids prepared in seawater with the new additive showed excellent rheological properties at temperatures above 300°F on a Chandler 5550 HPHT rheometer. The additive is compatible with fluid additives and is easy to apply. Dynamic tubing-blocking...

Moreover, this system has weak or no acidity at low temperature and slow release of H + at high temperature (120-150°C) in fractures, Its ultimate effective acid concentration is about 8% which is capable of effective acid etching. During pumping, this system shows less corrosion...
