... Abstract Hydrate formation in production and control lines has been a serious issue in the oil industry, especially in the deepwater offshore market. This article focuses on a compact temporary plant designed to be assembled on offshore rigs for heating and injecting high flow rate water...

..., a new coefficient is incorporated into the model to consider the impacts of the disconnected oil clusters during the cyclic injection. In addition, the end-of-cycle residual oil saturation (Som), which was required based on the Stone model, is no longer needed in this modified model. formulation...

... was adapted based on the studies performed by Lie (2013 ) and improved with filling the voids with spheres with controlled grain size to represent a porous medium and increase the permeability and porosity of the fracture. To study the effect of injection of low salinity waterflooding, a forced displacement...

.... To prevent all possible injection issues that were experienced earlier in the industry globally (early 1990's), a novel "design, execute, evaluate approach was introduced, this enables us to deliver reliable, single sourced start to finish solutions Subsurface drilling waste injection has been and continues...

... produced gas was injected into a remote subsea gas well injector to avoid gas flaring, in line with TOTAL's flaring policy. Methanol was continuously injected for hydrate inhibition. Unfortunately, at the end of the operation, a hydrate plug occurred in the 12-inch gas export line. Through a multi...

... Abstract Asphaltenes precipitation during carbon dioxide injection to enhance recovery has been considered as one of the major challenges in the tertiary production phase. How CO 2 would change the asphaltenes structure is still unknown. The present study investigates the effects of CO 2...

... with gas injections are being considered as EOR techniques. For paraffinic oils, such as alkanes, the presence of CO 2 decreases the IFT between oil and brine. However, for Pre-Salt oils with high concentrations of asphaltenes and resins, the effect of CO 2 injection on the oil-brine IFT has not been...

... compatibility with the existing upper completion design. Once the well was completed and the tree installed, injectivity testing was successfully performed confirming ICD functionality was re-established. The ICD completion design saved the operator a minimum of 12 hours online rig time, further simplifying...

The remediation job was conducted through a multi-step process involving a coiled tubing clean out, solvent-soak, and continuous AI injection through downhole chemical injection tubing...

... Abstract Water injection is a traditional method of secondary recovery used in the petroleum industry. Typically, even with the injection of water supplementing the initial energy of the reservoirs (primary recovery), less than 50% of the original volume of oil is produced. By altering...

Our data-driven algorithm learns the underlying reservoir dynamics from 3 sets of time-series, namely, (i) injection-rate, (ii) liquid and oil-rate, and (iii) number of producers. That is all the data we need...

...). Much higher concertation of surfactant than the optimally designed concentration in the EOR formulation has to be injected in order to account for the surfactant losses in the reservoir which often makes the whole EOR process uneconomical. Although extensive research has been performed with surfactants...
