... The reservoir fluid, containing significant concentrations of H2S and CO2, necessitates specialized handling to counteract its corrosive nature. Regularly, equipment at the wellhead undergoes wear, especially under high-pressure conditions, indicating the need for continuous technological...

... generally required a rig intervention. This paper summarizes a case study of the first application of water control in Yuralpa field using a Hydro Selective System (HSS) completion. It describes the relevant reservoir characteristics that lead to select this type of completion for Well YCCA-020 in a field...

... Abstract Achieving stable laterals for successful deployment of ICD sand screens with swell packers can prove difficult in Southeast Texas reservoirs due to hole instability, tight ECD margins, high clay content, and varying permeability contrasts. Historically, bore hole instability has...

... around the selection and execution of the drilling and completion fluids. Engineered water-based reservoir drilling fluid and post-drilling chemical "breaker" treatments were utilised for these open hole screen completions. The technology around the use of breaker fluid has evolved in recent years, yet...

... Abstract Water-based drill-in fluids (WB DIF) with high concentrations of lubricants and other materials that assist in reducing the fluid loss are commonly used to drill tight and high overbalance reservoirs in the south-west Persian Gulf. Exposure and damage of the formation by these products...

... Abstract This study investigates the evolution of acid stimulation to remove the near wellbore damage in producers at Penglai Oilfield which is the largest offshore oilfield in China. The near-wellbore plugging has been observed in certain wells within the unconsolidated sandstone reservoir. So...

... have been undertaken in recent years to separate H2 and Sulphur from H2S using various methods. In addition to deep gas reservoirs, hydrogen sulfide may be found in a wide range of other reservoir types. Due to their low use, these gas reserves often have little economic viability. Thanks to novel...

... Summary The objective of this work is to describe the extent of productivity decline due to fines migration during periods of increasing water-cut. Two models are presented which allow for estimating the formation damage due to fines migration in both homogeneous and heterogeneous reservoirs...

... Abstract The efficacy of low-salinity water flooding is attributed to various factors, including rock mineralogy, reservoir fluid composition, and the temperature and salinity of liquid-liquid and liquid-solid interactions. The objective of the proposed study is to examine the influence...

... Abstract To overcome the challenges in drilling, completion and testing for one of the highly fractured reservoir in West Kuwait oil field by intercepting the natural fractures and eliminating the causes of formation damage. An integrated multi-disciplinary study was carried out, to understand...

... water re-injection is implemented but improved predictions for how it will evolve is important for reservoir management purposes. Since such predictions conventionally are generated using simulators, robust and reliable experimental input data is crucial. There are many publications focusing...

... Abstract Polymer injection finds wide application in enhancing oil recovery (EOR) for heterogeneous reservoirs containing viscous crude. While injection of polymer effectively reduces mobility ratios toward favorable levels and enhances sweep efficiency, it necessitates consideration...

... their suitability. Two phases of corefloods looked at the compatibility of drilling mud and displacement fluid with reservoir core, and two further phases considered a range of treatment options. Treatment fluids included different strengths of hydrochloric acid, with and without solvent. The initial phases showed...

... Abstract Under-balanced Coiled Tubing Drilling (UBCTD) is a promising method for the redevelopment of unconventional mature reservoirs through re-entries. Yet, such projects have unique technical, geological and economic challenges. Thus, the commercial value is not fully realized...

...-fluid compatibility tests, and displacement tests were performed under simulated reservoir conditions. The collected data provided insights into the formation damage and the efficacy of the proposed treatment, contributing to a better understanding of the problem and potential solutions. The study...

... Abstract As fields in the Deepwater and Ultra Deepwater areas in the Gulf of Mexico have matured, the frequency of asphaltene deposition within the reservoir has increased significantly. Operators reported that solvent treatments show initial production response but diminishing results...

... Abstract Kuwait heavy oil development target reservoir is a shallow, sub-hydrostatic and unconsolidated sandstone with relatively high porosity and permeability. Due to nature of this reservoir, well intervention operations in North Kuwait Heavy Oil Asset exhibit a higher risk of significant...

... in reservoirs. Standard friction reducers were historically designed for potable water and to carry proppant into the reservoir by pumping fluids at a high flow rate. They were designed to utilize turbulence for transport, however their proppant carrying capacity is limited. To maximize proppant loading...

... treatment fluid reservoir Introduction Formation damage is a concern of exploration and production companies around the world. Irrespective of the damage mechanism – fines migration, clay particle swelling, precipitates, drilling inducted, etc., it is imperative that the damage be successfully...

.... Disadvantages may include: Fines may also plug pore throats in lower permeability strips. Potential formation damage deeper in the reservoir. This paper was selected for presentation by an SPE program committee following review of information contained in an abstract submitted by the author(s...
