... for this reservoir remained idle throughout the six years of dump-flooding, indicating that crossflow from the dump-flood did not go into the B3 reservoir. Due to these observations, well stimulation through wireline-conveyed shockwave pulsing was selected to stimulate the near wellbore area of the injecting...

... their approach on the fly based on actual downhole conditions. This manuscript presents a detailed case study that showcases the latest advancements in coiled tubing technology and their application in a complex trilateral oil well. The objective was to successfully access and stimulate the well using...

... two active producers with total oil production of around 100 BOPD. Paku field mostly conducted regular well intervention & well service (add perforation and pump recondition) to maintain/improve production, while special well stimulation like hydraulic fracturing was last conducted in 2016 on Paku...

... Abstract HCl based stimulation fluids occupy the dominant space in matrix acidizing of limestone reservoirs. To initiate wormhole propagation at high temperature/low injection rates and provide deeper penetration, the reactivity of HCl is generally retarded by emulsifying it with an external...

... stimulations that can be tracked all the way up to the execution stage. This paper presents the processes of identifying production enhancement opportunities, as well as the methodology utilizes to identify underperforming candidates and analyze well integrity issues. It describes how data science...

... Abstract Low permeability, naturally fractured reservoirs such as coal seam gas (CSG, coalbed methane or CBM) and shale gas reservoirs generally require well stimulation to achieve economic production rates. Coupling hydraulic fracturing and micro-proppant or graded particle injections (GPI...

... characteristics. The fluid will flow into the path of least resistance leaving large portions of the formation untreated. As a result, economic fracturing treatment options dwindle significantly, thus reservoir stimulation results are not always optimum. A multistage fracturing technique using Integrated Dynamic...

.... The initial stage is to select the suitable field for implementation Vibroseismic EOR. Then, the rock & fluid properties of the selected field are tested and examined by vibration and stimulation in the laboratory to obtain optimum frequency of 20 Hz S waves (circular / transverse) and 35 Hz P waves...

... Abstract Oil and gas companies operating carbonate oil and gas condensate fields in Kazakhstan have been carrying out acid stimulation activities leading to a substantial increase in hydrocarbon production. Nearly all treatments were considered a success. Nevertheless, a certain level...

... Abstract Several extended reach-restricted completion-smart wells required matrix acid stimulation using Coiled Tubing (CT). These wells are equipped with Mechanical Formation Isolation Valve (MFIV) in the tubing end which needs to be reopened by using CT to access mother-bore for performing...

... during stimulation. In this paper, we introduce a novel technique; Radial Jet Drilling (RJD) for Injection & Conformance Improvement which is practical & effective and has resulted in injection improvement of greater than 100% and at-least 3x sustained treatment result over conventional...

... Abstract One of the keys to successful and environmentally responsible well stimulation programs in coal seam gas development is to establish consistent procedures for the safeguarding, planning and executing activities across multiple wells. The aim of this paper is to show how a novel...

... Abstract The requirement for appropriate placement in matrix acidizing to achieve efficient, effective stimulation or removal of formation damage has long been recognized. Despite this, assessing the effectiveness of an acid treatment in terms of placement and treatment efficiency prior...

.... Matrix stimulation has been proven to remove the fines blocking the pore throat. The desired solution has been carefully selected to have prolonged well production. Organic clay acid is chosen for to its ability to have deeper penetration and to create a thin coating on the pore surface to prevent fines...

... Abstract When a well has been diagnosed with formation damage, the norm is for operators to propose reservoir stimulation via acid/solvent pumping. In Field T, located offshore Bintulu in Malaysia, mineralogy understanding is limited as cores available only represent a few reservoirs. For those...
