A solution for funding the development of technology in oilwell drilling

This article proposes a novel methodology to solve an existing gap in benchmark definition by the adoption of statistically defined benchmarks as references to test products or technical procedures. In a win–win partnership, remuneration is made upon realistic bases of comparison being proportional to existing risks. However, establishing values for benchmarks is rarely unanimous if asked to different persons involved in drilling analysis. Conventional benchmarking, which enhances few results and leaves aside poor operational performances, produces references that do not properly represent the geological environment. Nonetheless, when testing new products, it serves as reference to remunerate suppliers. The review of an optimization program, which resulted in a world record of drilling rate of penetration, reveals the financial magnitude of the savings produced, proposing the method discussed as a reliable solution to the development of technology.publishedVersio

New Industry Standards to Increase the Reliability of Drilling Operations

Design engineers select drilling bits based on their professional experience and knowledge about the area of the upcoming wells. Due to the absence of widely accepted algorithms for this task, diverse performance projections can come out if prepared by different persons. By selecting bits to withstand ranges of parameters similar to the used in offset wells, less failures and longer runs can be expected. In deeper wells, a slow increase in the modes of string harmonics makes well planning complex, becoming crucial for the endurance of drilling bits to avoid resonance. Two new standards are proposed to the Oil & Gas industry in this article, created to make well planning more effective and to increase safety in selecting drilling parameters at the rig. An environment of higher drilling efficiency will result in more reliable operations and lower operational costs
