Paper Number: SPE-192201-MS
... alteration quantification of rock samples. The results indicate that stearic acid stretching vibrational bands decrease with the decrease of brine ionic strength indicating a partial release of adsorbed organic material from calcite surface. Single ion brines impacted the calcite wettability and sulfate ions...

... that emulsified acids require 0.8 PV of fluid compared to 1.4 PV for 15 wt.% HCl acid package. The proposed system was determined to have negligible corrosion rate of 0.002 lb/ft 2 after 4 hours exposure at 300°F. Reaction kinetics study proved the delayed acid reaction with calcite by an order of magnitude...

... Calcium carbonate (CaCO 3 ), or calcite, is one of the most common causes of formation damage in the oil and gas industry. Calcite scale can plug the producing formation matrix, fractures or perforations which limits or completely blocks oil and gas production ( Al-Taq, et al., 2015 ). Calcite...

... from CO 2 -rich crude oil and gas, plays a dominant role in setting aqueous pH and speciation. A simple ion-complexing model predicts calcite surface charge as a function of composition of reservoir brine. The surface charge of calcite may be positive or negative depending on speciation of reservoir...

... of the solutes depends highly on the reservoir permeability distribution; preferential flow paths form in the high permeability layers. At 20 years, up to 11.6% anhydrite scale forms in the mixing zones of injection and formation waters and up to 18% calcite scale forms near injection wellbore (~ 10 m radial...

Paper Number: SPE-149095-MS
... with their cost per mass of rock dissolved, organic acids often have limited use in well stimulations. Recent thermodynamic modeling studies have shown that when an organic acid or a mixture of HCl and an organic acid reacts with calcite, a previously unrecognized reaction occurs. This reaction enhances...

... that the predominant minerals were calcite and dolomite in both samples. Determination of wettability using ESEM method is very cost effective. It is unlike other traditional methods. It doesn't use any chemical or even generate by-products; it is not time-consuming and provides better quality data at much lower cost...
