Flood-Injection Models
To return produced water to reservoirs, it must be suitably clean. Therefore, it must be tested and found fit for purpose. A water sample must be drawn and sent to an onshore laboratory for testing. Formation modeling would be based on the results. Unless the water is tested in situ, the values can change dramatically during transport and while waiting to be analyzed. Global Industrial Water designed and built a mobile, high-pressure-test system capable of mimicking the injection site exactly. The Portable Apparatus for Coreflood Evaluation—PACE—system (Fig. 2) is capable of finding the equilibrium between injector plugging and the magnitude of the fracture, defining changing leakoff aspects, and delivering accurate data. The system enables operators to feed test results directly to an on-site/onboard data-collection program producing immediate, accurate, and real-time results for the specific site. The system has been field tested on a rig in the Gulf of Mexico. This testing enabled real-time analyses of flood water with cores from that specific well. The data points were collected and the particle sizes determined by the onboard camera, after which the software analyzed the different filtration anomalies. Filter-cake data then were documented, informing the operator about the effects of that specific injection water on the matrix permeability.

Sulfate Reduction
The Global Industrial Water NFX nanofiltration membrane (Fig. 5) provides high-efficiency liquid separation. These membranes have an approximate molecular-weight cutoff of 150–300 daltons, with an average MgSO4 rejection of 99.3% or higher. This membrane rejects divalent and multivalent ions, while monovalent-ion rejection depends on the concentration in the feed stream. This membrane operates at lower pressures than reverse-osmosis membranes, offering lower energy and equipment costs for applications that do not require high salt-rejection rates. These membranes reduce levels of heavy metals, hardness, nitrates, sulfates, tannins, turbidity, color, and total dissolved solids, including moderate levels of salt, from feed-water streams. In addition, pH is virtually unchanged from the incoming source so that the permeate is not aggressive and will not cause increased corrosion. Field testing has shown possible increases in flux of 70–100% greater than current-industry-standard nanofiltration membranes. Removal of sulfate, which has roughly an 8% concentration in seawater, is key in reducing scaling at offshore platforms. If untreated seawater is mixed with formation water that contains barium and strontium, significant barium sulfate and strontium sulfate scaling and reservoir souring can occur. The use of nanofiltration membranes with high sulfate rejection and monovalent- and divalent-ion selectivity would be a cost-effective method for achieving sulfate removal.

Oxygen-Removal System
Global Industrial Water has developed a system to improve the offshore water-injection process. The Oxygon system uses no chemicals, weighs substantially less than conventional systems, and has a greatly reduced footprint. The membrane technology reduces the oxygen concentration in the water to less than 10 ppb. The system is rated to 300 psi and uses a simple cartridge-replacement process to reduce downtime. The compact skid design has a low total height and weight—30% less surface area than conventional degasifiers. As shown in Fig. 4, gases in the atmosphere dissolve in water until equilibrium is reached. Equilibrium between the liquid and gas phases is offset when a vacuum and/or source of strip gas is applied, thereby creating a driving force to move gases from the liquid phase into the gas phase. The system can be expanded to allow for redundancy with multiple contactors. O2, CO2, and N2 are controlled with one device. The system is environmentally friendly, is safe for employees, and does not require chemicals to operate.
