Reservoir monitoring is a key factor in the management of oil and gas resources. With the recent developments of permanent downhole temperature monitoring tools such as Fiber-Optic Distributed Temperature Sensing (FO-DTS), temperature transient analysis has evolved as a new alternative for reservoir monitoring. In this work, different techniques of temperature data analysis are presented for monitoring and characterization of hydrocarbon and geologic carbon storage (GCS) reservoirs. The objective of this study is to present new approaches that enable monitoring injection profile through vertical and horizontal injection wells using temperature warmback analysis. Application of temperature warmback analysis is also extended for …

Development Of Water Coning Control Design Metrics In Naturally Fractured Reservoirs, Samir Prasun
LSU Doctoral Dissertations
Naturally fractured reservoirs (NFRs) with bottom-water are known for their instant water breakthrough and severe water coning that reduces oil recovery. This is because water channels through the highly permeable fractures easily connecting the well to the aquifer bypassing the oil contained in the matrix. Remedial techniques such as producing below critical-oil rate, optimizing the well spacing and installing the downhole water sink (DWS)/ downhole water loop (DWL) technology, have already been successfully tested in single-porosity reservoirs (SPR). However, applicability of these techniques in NFRs are unknown since only a few studies have been performed on their feasibility in NFRs, …

The most recent and currently active delta lobe of the Mississippi River (MR) is the Atchafalaya-Wax Lake lobe, which was initiated approximately 400 years ago as a result of MR stream capture by the Atchafalaya River (AR). This capture process accelerated in the early to mid-1900s but further progress was prevented by construction and operation of the Old River Control Structure (ORCS) Complex. Many recent studies indicate that MR system below the ORCS is on a retreating geologic trajectory due to contributing factors such as sea level rise, subsidence, faulting, and declining hydraulic stream power. Diversions along the Lower MR …

Mass Spectrometric Calibration For Real -Time Hydrocarbon Detection, Makuachukwu Mbaegbu
LSU Master's Theses
Determining gas compositions from live well fluids on a drilling rig is critical for real time formation evaluation. However, development and utilization of a reliable mass spectrometric method to accurately characterize these live well fluids is always a challenging issue because of lack of a robust, quick and effectively selective instrument and method. The primary goal of this research is to understand reasons of such discrepancies in results between “good” spectra, and “poor” ones. The objectives are thus to identify the detection issues, calibrate and QA/QC the instruments, and analyze the results in lab settings. In this study, we used …

The Gas Assisted Gravity Drainage (GAGD) process was developed and patented by Dr. Rao at LSU in the early 2000s. The process involves the use of several existing or new vertical injection wells to inject gas and use the natural segregation of reservoir fluids from the density difference and the gravitational forces to displace the trapped oil and mobilize the oil downwards to be produced by a horizontal producing well. The GAGD process can be implemented as a secondary or tertiary oil recovery method. Several physical model experiments have been conducted to demonstrate the effectiveness of the GAGD process for …
