The well locations and targets mentioned in the email are a preliminary plan based on the previous geological results (only structural map, no geological model, 2015) and combined with dynamic analysis. Due to the tight early time and limited understanding of the block, there is still a lot of work to be done in the demonstration of the well location, including which well is used for sidetracking, drilling position, target coordinates of the target layer, well trajectory, etc., all need to be further demonstrated and optimized. <br>At present, we are speeding up various research work. We have completed structural interpretation, stratigraphic comparison, logging interpretation, etc., and are working on geological structure modeling (for details, please refer to the bi-weekly report). Some problems were encountered in the modeling process, such as oil-water contradiction. The next step is to analyze the reservoir connectivity in combination with seismic attributes. <br>From the current understanding, there is still a certain difference between the understanding of the previous results, so there is a greater uncertainty in the understanding of the remaining oil, which will inevitably affect the later well location deployment. Therefore, after completing the geological modeling and reserves calculation, we need to carry out the design of the reservoir engineering scheme, and then redeploy the side well positions and measures wells or other favorable targets proposed in the earlier stage, and hope to get the assistance of on-site experts. Work together to complete the well location deployment. <br>The work schedule is as follows: 2020.9 Completion of geological modeling and reserves calculation <br>2020.11 Completion of reservoir engineering scheme design <br>2020.12 Completion of well location design

The wells and targets mentioned in the email are based on preliminary geological results (only tectonic maps, no geological models, 2015), combined with dynamic analysis of a preliminary plan. Due to the tight pre-time, the degree of understanding of the block is limited, there is still a lot of work to be done to improve the well position, including the use of which well side drilling, drilling position, target coordinates of the target layer, well trajectory, etc. need to be further demonstrated and optimized.<br>At present, we are pressing ahead with various research work, have completed the tectonic interpretation, formation comparison, logging interpretation and other work, geological tectonic modeling work is under way (specific progress can be found in the bi-weekly report). In the process of modeling encountered some problems, such as oil and water contradictions, the next step combined with seismic properties for reservoir connectivity analysis.<br>As far as the current understanding is, there are still some differences with the understanding of the previous results, so there is a greater uncertainty about the understanding of residual oil, which will inevitably affect the later well level deployment. Therefore, we need to complete the geological modeling and reserve calculation, carry out the design of the oil storage engineering program, and then the previously proposed side drilling position and measure wells or other favorable targets for redeployment demonstration optimization, and hope to get the assistance of field experts to complete the well site deployment work together.<br>The work schedule is as follows: 2020.9 Complete geological modeling and reserve calculation.<br> 2020.11 Completion of the design of the oil storage engineering project.<br> 2020.12 Completion of the well level design.
