78624 results about "Petroleum engineering" patented technology

Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. Exploration and production are deemed to fall within the upstream sector of the oil and gas industry. Exploration, by earth scientists, and petroleum engineering are the oil and gas industry's two main subsurface disciplines, which focus on maximizing economic recovery of hydrocarbons from subsurface reservoirs. Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.

Intergrated reservoir optimization

A method of managing a fluid or gas reservoir is disclosed which assimilates diverse data having different acquisition time scales and spatial scales of coverage for iteratively producing a reservoir development plan that is used for optimizing an overall performance of a reservoir. The method includes: (a) generating an initial reservoir characterization, (b) from the initial reservoir characterization, generating an initial reservoir development plan, (c) when the reservoir development plan is generated, incrementally advancing and generating a capital spending program, (d) when the capital spending program is generated, monitoring a performance of the reservoir by acquiring high rate monitor data from a first set of data measurements taken in the reservoir and using the high rate monitor data to perform well-regional and field-reservoir evaluations, (e) further monitoring the performance of the reservoir by acquiring low rate monitor data from a second set of data measurements taken in the reservoir, (f) assimilating together the high rate monitor data and the low rate monitor data, (g) from the high rate monitor data and the low rate monitor data, determining when it is necessary to update the initial reservoir development plan to produce a newly updated reservoir development plan, (h) when necessary, updating the initial reservoir development plan to produce the newly updated reservoir development plan, and (i) when the newly updated reservoir development plan is produced, repeating steps (c) through (h). A detailed disclosure is provided herein relating to the step (a) for generating the initial reservoir characterization and the step (b) for generating the initial reservoir development plan.

Horizontal well directional sand blasting perforation and fracturing integral tool pipe column and construction method thereof

The invention relates to a horizontal well directional sand blasting perforation and fracturing integral tool pipe column and a construction method thereof. The tool pipe column comprises a safe joint, a first centralizer, a first rotating joint, a hydraulic sand blasting device, a second rotating joint, a second centralizer, a packer, a coupling positioning device and a guiding shoe, wherein the safe joint is arranged at the left end of the tool pipe column; the guiding shoe is arranged at the right end of the tool pipe column; the left end of the safe joint is connected with an oil pipe; the first centralizer, the first rotating joint, the hydraulic sand blasting device, the second rotating joint, the second centralizer, the packer and the coupling positioning device are sequentially arranged between the right end of the safe joint and the guiding shoe from left to right. The horizontal well directional sand blasting perforation and fracturing integral tool pipe column and the construction method provided by the invention have the advantages that the structure of the tool pipe column is simple; the directional san blasting perforation can be realized; the stratum energy is released to the greatest degree; the problem of shot hole compression zone of gunpowder perforation can be solved.
