Mineral Exploration Funds [PDF]

open access: yes, 1968
While independent mineral operators have traditionally been confronted with a scarcity of risk capital for mineral development, willing investors have often experienced equal difficulty in locating responsible mineral operations in which to invest.

Oil well perforation technology: Status and prospects

open access: yesPetroleum Exploration and Development, 2014
Perforation is a key link in well completion. To meet the development requirements of different types of oil and gas fields, after over ten years of research and development, a series of perforation methods and matching processes have been established ...

Significant production improvement using optimization of completion and artificial lift: case studies from South-West Iran

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Productivity of wells in South-West Iran has decreased due to completion and production problems in recent decades. This is a large risk against sustainable production from the fields.

Optimization of Fracture Spacing and Well Spacing in Utica Shale Play Using Fast Analytical Flow-Cell Model (FCM) Calibrated with Numerical Reservoir Simulator

open access: yesEnergies, 2020
Recently, a flow-cell model (FCM) was specifically developed to quickly generate physics-based forecasts of production rates and estimated ultimate resources (EURs) for infill wells, as the basis for the estimation of proven undeveloped reserves.

Vibration Characteristics and Safety Analysis of Completion String in High Pressure and High Gas Rate Well

open access: yesShiyou jixie, 2022
The present research on vibration of completion string in oil and gas wells does not consider the lateral and longitudinal coupling of string induced by gas, however, actually, the string and the fluid in the pipe have lateral and longitudinal ...

Unconventional Oil Reserves Development in the Viking Play (Western Canada) Using Horizontal Wells and Hydraulic Fracturing

open access: yesGeoresursy, 2017
Oil production from the Viking play in Saskatchewan province started in the 1950s and continues since that time. Horizontal drilling and multistage fracturing have caused resurgence in development of this play.

Production system and method for producing fluids from a well [PDF]

open access: yes, 2002
A production system and method for producing fluids from a well are presented. The production system may include a submersible pump and a jet pump. The submersible pump may be arranged within the well.

Determination method for maximum allowable value

open access: yesAll Earth
In recent years, the annular pressure caused by rising annulus pressure in marine oil and gas wells has become an important factor affecting marine oil and gas exploitation, so it is very important to study the maximum allowable value of annulus pressure

Synergetics of geological mediums and its impact on the effectiveness of the exploitation and exploration for mineral deposits

open access: yesМінеральні ресурси України, 2019
The mechanisms of joint influence of mountain and reservoir pressures, saturating fluid, structure elements of rocks and external dynamic effects on their behavior in natural conditions, in particular near of the well, are investigated.

Determination of vertical and horizontal permeabilities for vertical oil and gas wells with partial completion and partial penetration using pressure and pressure derivative plots without type-curve matching

open access: yesCT&F - Ciencia, 2005
 it has been long recognized that in some reservoirs the flow does not follow the expected radial cylindrical pattern. Spherical flow may take place in systems with wells completed in thick reservoirs where a short completion interval is open to flow ...
