... as, taking real-time actions to increase the production. Background The natural flowing wells, producers of the Vaca Muerta formation, in the Loma Campana field, present several problems associated with paraffin deposition (which causes restriction of production flow in both tubing and choke...

... segment. In front of the pig a slug of paraffin was formed and impeded its passage. During two years the production continued through the still open West segment of the production flowline. A wax mitigation plan was implemented, consisting of continuous paraffin dispersant injection. Meanwhile, low-cost...

... paraffin and mitigating deposition. However, it is a new technology, and there is still much knowledge to be gained about this technology. (3) When the above methods fail, a coiled tubing or workover rig is usually the last resort. Coiled tubing can be used to mechanically remove the plug by milling...

... in a PVT lab, using mixtures of methane and n paraffin based emulsions as unweighted drilling fluids, tested at the temperatures of 158, 194 and 302o F. The pressure, temperature and fluid composition effects on those gas-liquid properties were analyzed and the experimental data for solubility...

... Abstract This paper presents a case history of inspecting, cleaning and re-establishing communication in a deepwater pipeline that had plugged because of paraffin deposition over an extended period. Early mitigation attempts did not remove the solid mass causing the blockage but, rather...

... was only 65%, 50%, and 77% for the chemical, jet, and radial cutting torch cutters, respectively. It was found that some cutting failures could be attributed to specific causes, such as heavy paraffin in the well, improper detonation, low-pressure tool leaks, exceeding tool pressure limits, and improper...

... Abstract The deposition of paraffins was studied in a laboratory simulation of the subsea operational conditions, where the oil pipelines laying on the seabed are subjected to low temperatures. An experimental apparatus was built for a pipe-flow model submerged in a chilling bath of near frozen...

.... It is described how in several operating areas, aromatic solvent usage has been completely eliminated in favor of terpene solvent blends. Solvents are primarily used to clean and remove damaging organic deposits, such as asphaltene and paraffin, from wellbore tubulars and the formation matrix. Paraffin...

... infrastructure. Examples include Pompano Phase 2 1 , which is produced more than 4 miles back to the Pompano host Platform, and Troika 2 , which is produced more than 14 miles back to the Bullwinkle host Platform. Within these offset distances, use of solely theoretical models to make paraffin deposition...

... segregation and vaporization of light hydrocarbons were the main elements of the displacement mechanism. However, well founded arguments have arisen about anomalous interfacial phenomena and precipitation of some oil constituents during the recovery process since the oil was strongly paraffinic...

... Abstract Highly paraffinic crudes were characterized by means of physico-chemical analysis (pour point, cloud point and API gravity) and hydrocarbon analysis (wax content, paraffin class-type separation, gel permeation chromatography and high temperature simulated distillation). Although all...

... describes a six month pilot test for the control of paraffin and asphaltene deposition at the reservoir level using naturally occurring microorganisms. For the course of the paper, paraffin will be defined as pentane soluble hydrocarbon precipitates. Likewise, asphaltene will be defined as hydrocarbon...

... ABSTRACT Five wells with a history of paraffin related problems were selected for treatment with a commercially available bacteria product∙ Wax deposition was so severe in these wells that production was often halted due to stuck rods. Wax deposition was controlled by hot oiling. Some wells...

... ABSTRACT Selection of crystal modifier chemicals to reduce the pour point of paraffinic crude oils and to provide paraffin deposition inhibition has, in the past, been accomplished by laboratory physical testing. This paper presents a method for selection of these chemicals based on a technique...

... ABSTRACT Paraffin and scale deposition in wells at Conoco's Chittim lease has consistently hampered operations. Numerous chemicals were laboratory and field tested to determine the two most cost-effective chemicals for paraffin and scale treatment. These were a paraffin solvent and a sulfamic...

... Abstract Factors that influence paraffin deposition were investigated in laboratory experiments. An apparatus was built that measures the pressure and flow rate changes caused by pressure and flow rate changes caused by paraffin deposition from crude oil in one-half inch paraffin deposition...
