Archive of thin-plate and thin-shell finite element programs written by Peter Bird at the University of California in Los Angeles (UCLA).

Simple program that illustrates the enormity of the Geological Time. Allows the user to enter a date before present (using different units of time) and the program calculates the corresponding date and time using the calendar year as a scale representing the age of the Earth. Available only in Spani ...

As the search for petroleum resources become more extreme in terms of depth, pressure, and temperature (HPHT drilling), wellbore circulating temperature prediction becomes a very crucial process. It has implications for flow assurance (wax, hydrates, and viscosity), stress analysis, drilling tool te ...

Casing strings are an indispensable asset to prevent the borehole from caving in, protect water sands from contamination, and control pressure in the well. They also serve as a path for production tubing, making it essential to determine a suitable casing string that can resist all potential loads w ...

Casing wear during drilling and workover is an on-going concern. It will continue to have an impact on both well path and operation designs because it can cause catastrophic incidents such as oil spills, blowouts or even the loss of a well. PVI has conducted studies on casing wear from both an exper ...

Casing centralization is one of the key elements to ensure the quality of a cementing job. It does so by preventing mud channeling and poor zonal isolation. While centralizers are used extensively, well problems continue to arise due to poor cementing jobs. The challenge that both operators and serv ...

A successful cement job is one of the most important factors for of any well. There are many challenges involving increased reservoir depth, downhole temperature and pressure. Achieving wellbore integrity is more complicated than ever before. To overcome these challenges, PVI developed CEMPRO, an in ...

The ultimate yet most difficult goal of cementing operations is to provide zonal isolation by displacing drilling mud with cement slurries. Incomplete mud removal creates a poor cement seal and non-productive time (NPT). To ensure critical zonal isolation with mud removal optimization, PVI has devel ...

Cementing operation success or failure can potentially make or break the financial viability of a well or project. It is vital to correctly perform calculations and prevent mistakes during the design stage of a cementing job. As new technology evolves, the calculations of various parameters for ceme ...

CEMLab aids experts and technicians in creating globally consistent slurry formulations and in rapidly disseminating cementing techniques. It standardizes the slurry design and provides a common historical support base for multiple cement labs worldwide. Slurry design and testing are integral parts ...

The first step to ensure an optimum completion is to remove leftover drilling fluid residue and casing debris. This requires that the drilling mud be changed out with solids-free completion fluids. Completion fluid displacement involves multiple fluids sequenced in circulation. Varying flow rates, f ...

Cement is fundamental in maintaining integrity throughout the life of the well. Even if the slurry has been properly placed, changes in downhole conditions can induce thermal and mechanical cycling stresses to harm the integrity of the cement sheath. PVI is developing CEMLife, a software package tha ...

At Earthworks we regularly have to load and check 3D seismic cubes and well locations. In order to check the relation between UTM coordinates and Inline/Crossline positions we have coded up a simple LocationCalc routine. This can be used to determine cube corners from an origin and orientation or al ...
