Wireline Formation Testers have been used in the petroleum industry for decades to provide accurate formation pressure measurements and fluids properties with wide range of applications through all the stages of in the life of a reservoir; exploration,appraisal,development,production and injection. Wireline formation testing done mostly using cable-operated tester and sampling tool anchored at depth while reservoir communication is established through one or more pressure and sampling probes .Traditionally, the selection of the formation pressure and sampling points rely on conventional resistivity and porosity logs. These logs often fail to produce optimal results because of the complex nature of the dual-porosity carbonates in South Iraq. The work illustrated in this paper tried to optimize the selection of formation pressure and sampling points by the utilization of high-resolution azimuthal log measurements such as borehole images. The use of a high-resolution electrical borehole image log helps place the tool probes at optimum depth locations and pinpoint the "sweet spots" suitable to achieve the best results of formation pressure and sampling measurements.

This study deals with a lazy well completed with no packer in place. The main producing formation is showing strong signs of depletion where it lost more 2000 psig of reservoir pressure since the production started. Previous experiences in this well and other offset wells show there is demand for Nitrogen Injection Through Coiled Tubing Unit in the tubing in order to lift the well and bring it online whenever the well is shut-in for any reason. Direct natural gas injection at the casing head is a cost-effective alternative to rigless well lift operations. However, this is a challenging thing to achieve since it requires precise knowledge of injection rates and casing head pressure, additional to that formation fracture pressure and other reservoir characteristics should be taken into consideration. Data were collected and dynamic wellbore is created and linked to near well reservoir model to capture the transient behavior of the reservoir during start-up process. From Dynamic Modeling and simulation of the production system, best injection pressure, production choke, injection time and quantities are estimated and optimized for more efficient lifting process. After Initiating the well, production stability is observed in the transient simulator to ensure the success of the well lifting method. This method of production initiation is cost effective, and if implemented properly should bring the well back in production fast. Successful implementation this method demands a precise wellbore model to be created and shut-in surveys should be used to match the well status when it's not producing to tune the wellbore and fluid parameters.
