Kaizen For The Work Over Part In Company CS

After56years development of Chinese Oil&Gas industry, CS, as the biggest offshore Oil company in China, some oil field has fallen into the brown-flied period, e.g. a worsen downhole status, more workover required, unplanned shutdown. The biggest dilemma lay in front of CS is how to make the workover in a more efficient and cost saving manner. This dissertation is based on the Kaizen Theory, to analysis the application of this theory for the Workover of Company CS.First, to analysis the status of workover of CS, chose a fit for purpose strategy for the future development of workover, while try to eliminate the disadvantage. Secondly, to raise the four main issues, Unspecific Target, Influent Process, Uncontrolled Schedule, inefficient Site Management. Accordingly, the resolution which follow the Kaize principle is divided into four parts:Target Management, Work Flow Management, Schedule Management and Offshore Management. For Target Management, by introducing the PDCA circle, to have PDCA time sheet with a specific operation circle, cost for single well and workover duration limitation; for Work Flow Management, by introducing the5W1H(what, why, where, when, who, how) and ECRS (Eliminate, combine, rearrange, simplify) theory, to optimize the workover process, payment process and logistic process; For Schedule Management, to expedite the workover by controlling the5elements, personnel, equipment, procedure, loose items and weather; For Offshore Management, to apply the5S theory according the5elements mentioned above. At last, an execution plan is made for specific management process.
