Abstract Gas Lift Real Time Monitoring System (RTMS) provides the real-time gas injection pressure, casing head and tubing pressure of lifted wells. This system captures surges in and/or causing chaotic undesirable fluctuations. The production from continuous lift wells can be severely unstable behave as intermittent lift. trend loss is norm for systems. oscillating flow affects processing equipment lead to grid shutdown. Casing heading prominent instability low wells, producing a...

Abstract The paper describes the feasibility of revisiting old sands, for improving recovery factors and enhancing production, which otherwise were already abandoned. also outlines systematic methods predicting onset liquid loading in gas wells, evaluation completions optimization comparison various deliquification techniques. ONGC is operating two fields eastern western regions India. Earlier both fields, many sands had to be closed/isolated after wells ceased flow due absence continuous...

It one few fields world operating entirely on Electric Submersible Pumps with 36 wells 5 wellhead platforms producing 62907 barrels liquid per day an average cut 68%. The performance ESPs being continuously monitored field. With continuous improvement, run life has increased months to 3 years. Despite improvement life, unexpected failures still occur time time....

Abstract This paper aims to elucidate the various benefits of continuous dosage suitable scale inhibitor into reservoir through injection water prevent down hole deposition in offshore development wells. Various consequences inadequate chemical dosing have been deliberated. Detailed description methodology adopted for selection has also elaborated paper. Most oilfields India's Western Offshore region are brown/matured fields which production more than three decades. Reservoir pressure...

Abstract The operation of gas lift valves the systems at field scale is controlled by nitrogen pressure charged in dome. Nitrogen influenced injection temperature and production fluid temperature. In wells completed water drive reservoirs, emulsion flowing with high cut causes an increase opening topmost (GLV). When these are shut or provided low supply pressure, get loaded minimal taking place. depletion lower reservoir a decrease bottom-most valve, causing higher lowers grid pressure....

Abstract The acoustic method with echo sounder is used to determine the annulus liquid level in rod pumping systems installed at different onshore fields of Mehsana Asset. limitation difficulty finding pumped off well among huge population lift on day-to-day basis. motor current sensor RTMS can be real time dynamic level, five cases validating efficacy this innovation. important tool analyzing subsurface pump condition. Real power three phases calculated from current. Power torque...

Abstract Conventionally, a cylindrical channel square-edged port is used to transport the gas from annulus tubing. However, insufficient injection, incorrect diameter size, and injection rate variation generally result in unstable flow condition with such ports. To overcome these problems, multiple Converging Gas Lift Ports have been designed an objective stabilize thus minimizing fluctuation tubing pressures. This technology has applied 13 lift wells resulted liquid production increment of...

Abstract Analysis of recovered scale samples deposited within Electrical Submersible Pumps in offshore wells was carried out. The primary objective includes the identification root cause deposition and suggesting remedial measures for removal prevention. Many an field ONGC are facing acute problem decrease pump efficiency ultimate failure due to inorganic scale. methodology carrying out study consists a detailed Compositional sample retrieved from inside ESP one affected wells. Additionally,...

Abstract Field Alpha is situated about 200 km West of Mumbai city in a Deep Continental Shelf at the water depth 85 - 90 m. The existing facilities consists 5 Well Head Platforms (WHP) connected to FPSO through subsea PLEM and riser system. A total 36 wells from well head platforms field are producing 61348 blpd with an average cut 68%. All these Electric Submersible Pump which one most effective economical means lifting large volumes liquid. current paper attempt address various issues...

Abstract The paper aims to elucidate the process undertaken identify suitable inhibiting chemical prevent down hole deposition of scale in ONGC western offshore wells by means a squeeze job. Detailed description methodology adopted for selection has been elaborated paper. Most fields ONGC's Western Offshore region are brown/matured with depleted reservoirs pressures. Seawater injection is one primary techniques used combat depleting reservoir pressure. This led rampant escalation scaling...

Abstract Multiple ESP wells in an Indian Offshore Carbonate reservoir were afflicted with inorganic scale deposition chronically. Analysis of recovered deposit samples was carried out and the root cause established. This followed by successfully carrying remedial operations for removal prevention. The experience gained from same has been elaborated paper. Inorganic Electrical Submersible Pumps a big concern many carbonate Offshore. Scale ESPs causes decrease pump efficiency sometimes,...

Abstract Analysis of tubing failure SRP wells with respect to uniform corrosion, pitting and mechanical abrasion has been carried out. The primary objective includes the identification root cause suggesting alternate metallurgy. Many in an onshore field ONGC were facing acute problem general rod-tubing wear. methodology for carrying out study consists a Failure retrieved sample failed from one affected wells. This included thorough visual inspection, Scanning Electron Microscope analysis...

Abstract The paper aims to discuss various issues pertaining gas lift system and instabilities in low producer wells along with the necessary measures for addressing those issues. effect of parameters such as tubing size, injection rate, multi-porting valve port diameter on performance analysis integrated flow stability have been discussed paper. Field X is one matured offshore fields India which has producing over 40 years. It a multi-pay, heterogeneous complex reservoir. field through six...

Abstract Objectives In wells which are producing on intermittent gas lift (IGL), the injected cannot sweep entire liquid volume to surface from bottom of tubing as there is continuously some fluid falling back in tubing. The fallback can be described difference between slug at start injection and actual produced surface. This happens due fact that has a tendency flow through letting fall. intensity increases more when increase pressure wellhead. order minimize this lift, sweeping pipe bend...
