... Abstract This paper provides a comprehensive overview of the TAML Level 2 multi-lateral well by the Field Operator, which features a permanent limited entry liner completion in both laterals to enhance the reservoir productivity. The well marks a significant technical achievement...

... Abstract This paper aims to analyze the impact of appraising and developing marginal fields with multiple stacked reservoirs which is quite challenging in terms of techno commercial value. The development of such marginal reservoirs using conventional single horizontal wells drilling...

... There were 4 bottomhole and surface samples from those reservoirs to be evaluated. Standard PVT experimental procedures were carried out to measure fluid properties, including expansion and depletion studies (CCE, DLE, separator and viscosity experiments). Fluid characterization using Equations...

... is often considered to prevent reservoir souring over time. Seawater contains organic material which often reacts with formation water that may increase the scaling tendency therefore requires scale inhibitor treatment. This reaction and exposure may introduce oxygen within the water which requires de...

... pressure in oil reservoirs, the high investment treatment costs for produced water with high hydrogen sulfide content, and the compatibility between produced water re-injection and reservoir compatibility have become prominent issues. It is urgent to maximize the economic benefits of oil fields and meet...

... Abstract In a natural dump-flood well that has been progressing for approximately six years, observations were made that only one of the two intended low-pressure oil reservoirs – B2 and B3 reservoirs – is receiving water from the high-pressure aquifer in the same source well. The B2 reservoir...

...Case UGS introduction The study case is XGS UGS, which is converted from a depleted gas reservoir with 34 years of production history, located in the Sichuan fold-thrust belt area of Southwest China. The UGS structure is a steep, narrow, and long anticline, controlled by 5 reverse faults...

... the reservoir's performance, in particular, the production indicator and the decline indicator. The output index is calculated using the average daily oil production in each offset well over the first three months. The water cut in each offset well during the last month indicates that the reservoir is depleting...

... configurations with distinct zones having multiple reservoir layers isolated by packers behind the tubing. The flow events in such cases happen behind the point of measurement and PLT sensors are blind to respond to them. Another technique is introducing tracer materials into injection water to establish...

... on Well Complexity In the late 1990s, the oil and gas industry witnessed a surge in interest towards multilateral completions, spurred by the potential for enhanced reservoir contact and optimized production strategies. This growing focus led to the development of an increasingly diverse array...

... Abstract The manipulation of reservoirs in different energy sectors, encompassing geothermal production, gas extraction, and the storage of gases like carbon dioxide, air, and hydrogen, frequently leads to seismic events and surface deformations as prominent consequences. The deformations...

... with wind and solar power. Jilin Oilfield is characterized by typical low-permeability reservoirs with complex micro-pore structures, poor porosity-permeability correlation, developed micro-fractures, and strong heterogeneity [ 6 ]. The primary development method involves continuous water injection...

... Abstract Rapid screening and optimization of CO 2 enhanced oil recovery (EOR) process in unconventional reservoirs is urgently needed but challenging due to the complexity of this process and poor understanding of seepage in multiscale porous media. To address this issue, an interpretable...

... enhance the utilization of the selected storage site. The methodology of this study involves conducting numerical simulations on a synthetic model that replicates the characteristics of a heterogeneous field with two anticlines. The analysis is conducted on two cases representing a depleted gas reservoir...

... Abstract CO 2 fracturing and flooding have become key technologies for increasing shale oil recovery. However, for shale reservoirs with high wax content, the production data from Daqing oilfield indicate lower later-stage recovery rates and a significant occurrence of wax deposition during...

... seven gas wells and seven oil wells. The field structure is a gently-dipping anticline which is divided into eight (8) main fault blocks (from A through G) out of which only three are developed fault blocks: C1, C2 & B while the other five Fault blocks are remained undeveloped: The reservoirs...

... Abstract Deployment of Autonomous Inflow Control Valve (AICV) technology in a Sabah water field aims to improve reservoir sweep efficiency and increase hydrocarbon recovery by addressing gas and water breakthrough in thin layer oil rim horizontal wells. The automation of inflow control valves...

... over stretching as shown in Figure 1 , where the lower completion ICDs were stuck in the closed position, even with multiple attempts to mechanically shifting the ICDs. This malfunction effectively locked the production potential of the wells, preventing any fluid influx from the reservoir...

...Well test model The well test models targeted are the single model and the dual-porosity media reservoirs with pseudo-steady state model, both at infinity. These models are used to generate the curve to be tested at the input of the SPAIM and the target curve for the self-test within the SPAIM...
