Streamlining and Automating Geological Requirements for Development Wells

Abstract

Development wells are drilled for different purposes that varies based on the business needs. Some scenarios can be for flowing production, power water injector, gas, or to monitor the performance of a well. Coupled with the technology in wellbore drilling activity and the artifacts that are required for the workflow approval. Through evolving technology, the system captures every step of wellbore activity to address the business needs and streamline the approval process. Data fuels Industry Revolution (IR) 4.0 and effective data analytics is the prerequisite for successful implementation of digital enterprise applications. Well approval is an in-house developed system embedded in Petrel application for reservoir characterization geologists. It standardizes well approval documents across the organization. The geologists may generate multiple well approval documents in case a change in the plan has occurred. Different scenarios require geologists to replace the plan that reflects the well approval document. Planning is the main pillar in the process of Well Approval, and automating the planning part simplifies the well approval process. The system automates the generation of three critical documents. First, Integrated Requirements (IRs), which consists of logging and threshold values for each hole section generates the reservoir amplitude impedance and porosity maps, and finally allows the geologist to capture seismic maps from 3D geological models. Second, Prognosis geological horizons details. Third, Location Evaluation. The backbone of this system is that it is integrated with different back-end systems such as corporate database, Petrel, Openwork and Geolog. In addition, geologists are not required to select the offset wells. The offset wells algorithm designates the wells for geologies based on specific criteria that is built in the system such as reservoir type and dynamic log selection. The system tackles both environments 2D and 3D based on the giving parameters such as facie. The system is able to detect the environment and prepare the documents accordingly. Since the system is aligned with the business pattern for well approval process, it significantly improves the time required to create these documents from two to three (2-3) days to less than 1 hour (90%) and the data will be readily available through Real-Time Operations Center Knowledge System (also known as ROCKS) for further analysis and reporting.
