... Abstract This report discusses experienced lower C2 / C2+ recovery in NGL recovery unit of Saudi Aramco Khursaniyah Gas Plant Department (KGPD). The experienced lower recoveries were due to the unplanned outage of HP gas and no available HP gas feed to NGL plant. This led to uneven flow...

...). This paper covers two phases of that study; Phase I was the initial high level study of HUS and using CO 2 /N 2 for Enhanced Gas Recovery (EGR) to maximise hydrocarbon recovery and provide a cushion gas prior to storage. Phase II is more detailed and focusses on the store itself as it is slowly ramped up...

... and controlled increase in gas-oil-ratio for most scenarios. AICV used in segmented reservoirs shows the largest potential to reduce unwanted fluids and in addition increase oil recovery. In cases with uncertain aquifer and/or gas cap strength, or large variation in effective permeability, the AICV will make...

... Abstract Oil and gas will be the main part of our future energy sources, despite of emerging and expanding of renewable energies. Enhanced Oil Recovery (EOR) plays an important role in the future oil and gas industry as the conventional oil reserves will shrink. Heavy oil reservoirs...

... = u T f w + K λ o f w ∂ P c ∂ x . Abstract Solutions are presented to predict 1D counter-current spontaneous imbibition oil recovery at early and late times, i.e. before and after the imbibing water reaches the noflow boundary based on knowing the capillary...

... Abstract Among the many parameters needed to optimize a polymer flood is the choice of polymer viscosity, mobility ratio and polymer slug size that should be injected to maximize oil recovery. In this paper, a new polymer flooding experimental study is addressed to answer two questions. Firstly...

... and low total acid number (TAN) crude oil, core mineralogy, and composition of the nanofluid on wettability alteration and recovery. Nanomaterials used in this work employ inorganic nano-sized particles in a colloidal particle dispersion. One nanofluid utilizes surface-modified silicon- dioxide...

... The approach helps to confirm whether the main recovery mechanism of smart-water injection is interfacial viscoelasticity or wettability alteration or a combination of them. Furthermore, an attempt has been performed to confirm if the combination of smart water with polymer flood could sweep...

... models were constructed using data from the Khazzan field in Oman. The impact of layering, permeability and drainage area on well performance is also investigated. The contribution of each layer to recovery and the mechanisms controlling that contribution is explored. The investigation shows...

... an analytical approach to evaluate the recovery from a two-layer porous media system. Their model showed a dramatically decreasing recovery with increase in heterogeneity in the form of the permeability ratio (range of 1.0-10.0) between the two layers of the system. Bahralolom, Bretz [29] witnessed...

... Abstract This work provides an extensive review on Low Salinity Water Flooding (LSWF) recovery mechanisms, as well as an evaluation of its synergies with Polymer Flooding (PF). Thereby, a critical state-of-the-art evaluation on LSWF and PF mechanisms is combined with selective laboratory...

... Abstract Shale gas reservoirs hold adsorbed gas in kerogen. Laboratory techniques have been developed to measure the gas amount in samples. However, adsorbed gas recovery is an unsettled issue. Complexity is mainly due to adsorbed phase having an unknown composition and density, and desorbing...

... and/or fluid injection, in normally consolidated reservoirs; would remove energy from the system and impact oil recovery. However, in an unconsolidated sand reservoir, the real risk is that the reservoir compacts, reducing the porosity and permeability, and risking oil recovery if adequate voidage...

... interactions. Currently, there is limited understanding of how these complicated flow mechanism impact gas flow and the ultimate gas recovery in such reservoirs and what are the parameters that control the production. To improve this understanding, we present in this work a simplistic numerical modelling...

... injection procedure and to investigate the role of core wettability on final oil recovery. Experiments Abstract An experimental study of polymer flooding is here presented focusing on the influence of initial core wettability and flood maturity (volume of water injected before polymer injection...

... Abstract Smart water injection or low-salinity water flooding is an enhanced oil recovery technique for fractured reservoirs. The mechanism of low-salinity water flooding is performed by altering the wettability of rock towards water-wetness. This study presents an evaluation of low-salinity...

... Abstract The high residual gas trapping characteristics of low porosity rock are a considerable challenge for recovery of fields with bottom or edge water. Water lifting and handling is often a practical issue. Perforated intervals may suffer from permanent loss of gas mobility related...

... recovery from methane hydrate-bearing sediments. The recovery of methane gas from hydrate dissociation through pressure depletion at constant pressure was studied at different initial hydrate saturations in cylindrical sandstone cores. Core-scale dissociation patterns were mapped with magnetic resonance...

... of drainage area and fracture interference. Many operators use a method known as parent well protection (PWP) to help mitigate this effect and increase recovery from both parent (delineation) and closely offsetting development (child) wells. This paper presents an analysis of the economic impact of PWP...
