In bulk conditions, viscosity and microscopy characterization of tight w/o emulsions (up to 99:1 W/O) highlighted that low shear rate and very low emulsifier concentration in the mud filtrate promote very viscous and thermally stable emulsion. Besides linear coreflood tests proved dramatic permeability impairment when flushing CaCl[2] brine through a mud filtrate saturated core, confirming the formation of a blocking phase in the porous media.A prevention system has been engineered as a peculiar surfactant to be added to completion brine, able to prevent emulsions from forming instead of simply breaking it up.Surfactant selection guidelines have been provided as result of various additives screening being focused on the main characteristics affecting the surfactant efficiency, like HLB and solubility in brine.IntroductionDuring drilling and completion many factors concur to induce severe formation damage, especially in low performance wells producing from depleted reservoirs. A representative case for mature basins is the Adriatic Sea, whose reservoirs present problems and constraints related to the particular formation, characterized by interlayers of overpressured shales and depleted sands.In order to take into account for this differential depletion, drilling mud must be over weighted causing the filtrate to enter the producing sand so deeply that perforations are not able to bypass the filtrate invaded zone.While drilling formation fluids (gas and connate water) and OBM's filtrate invasion may interact giving rise to mechanism that alters the pay zone permeability through wettability change. When perforating, if tunnels do not bypass the near wellbore invaded zone, as previously seen, additional damage may negatively affect rock permeability, through mechanisms related to completion brine and OBM filtrate incompatibility[1].When the completion brine enters the porous media contacting the filtrate front, a blocking and high viscous two phases system (probably an emulsion) may form (Fig. 1), with strong impact on well cleanup efficiency and therefore on productivity.The objective of this paper is to design and select an additive able to prevent emulsion from forming, especially when perforating a well in brine previously drilled with OBM. Additives selection criteria were fundamental for engineering an effective and efficient system, guaranteeing the selected additive to be:soluble in brine;not affected by brine salinity;not temperature dependent;environmental friendly;operationally feasible.Successful field applications of one of the selected products, as prevention jobs, will be presented in this paper to prove that what experienced during lab testing has been also confirmed through operative procedure in terms of feasibility, efficiency and last, but not least, in terms of costs. Moreover these positive results push on for future study addressed to tailoring a system, not just for prevention purposes, but also for remedial jobs.
